How to Use Blastr

Overview

Every blast goes the same way:

1. Connect your socials. Link your YouTube channel, Instagram and Facebook Page, and TikTok account to a workspace. You only do this once per workspace.
2. Start a blast. Press New blast on the home screen, or drag files onto any page of BLASTR. You can add several videos and photos at once.
3. Fill in one page. The composer holds everything: the cover, the caption, and a row for each platform. A checklist at the bottom tells you when it's ready.
4. Send it. Blast now, or pick a time from the arrow beside the button. BLASTR shows live progress for every platform.

On a computer, the sidebar on the left takes you everywhere: BLASTR (the rocket), Connections, BOOSTR, Library, Sounds, your workspace's settings and your account. On a phone, the same places are in the bar at the bottom of the screen, and your account sits behind your picture at the top right.

Connect Your Socials

Open Connections from the sidebar or the bottom bar. Each platform connects through its own official login, so BLASTR never sees your passwords.

Each card shows a status line in plain words: Connected. Renews by itself., Expires in 5 days. Reconnect to keep posting., or Needs reconnecting. Posts here would fail. Use Reconnect to refresh a login and Disconnect to remove one. If posts are already scheduled for that platform, the confirmation tells you how many.

Your First Blast

Press New blast and pick your files, or drop them anywhere on BLASTR. Everything happens on one page, the composer. Uploading and converting start the moment a file arrives, so you can write while it finishes.

1. Pick a video. The row at the top shows every file in this blast. Tap a tile to work on it, + to add more, and × to take one out. Each tile carries a badge: a green check when it's ready, a ! when something is worth a look, or a red count of things to fix. With more than one video, Copy settings to all copies the platforms and their settings (never the caption, cover or time).
2. Check the cover. BLASTR picks a frame from the middle of the video automatically. Change cover lets you scrub to a different frame or upload your own image, and Go back to the auto pick undoes it. The cover is used on YouTube and as the Instagram Reel cover. Preview shows the cover with each platform's caption cut off where that app cuts it.
3. Write the caption. One caption goes to every platform. See Captions for the YouTube title, handles and snippets.
4. Choose platforms. Each platform has a row with a switch and a one-line summary of its settings (Everyone · comments, duet, stitch on). Tap a row to open its options. A platform that isn't connected shows Connect instead of a switch.
5. Send. The big button at the bottom says what it will do: Blast 2 · all now, or Blast 1 · and schedule 1. The arrow beside it opens the time menu (see Scheduling).
6. Ready for launch. Pressing the button shows every video, where it's going and when. Tap a video to change it, Edit to go back, or Ignition! to send.

The checklist

The pill at the bottom left reads Ready, 1 to check or 1 to fix. Tap it to see the list. Each item has a button that jumps straight to the field it's about.

• To fix stops the blast. Examples: no platform picked, TikTok's Who can view not chosen, a scheduled video with no time, or an upload that failed. Pressing the send button anyway shakes it and opens the list.
• To check never stops anything. Examples: no caption, a YouTube title over 100 characters, a clip too long for an Instagram Reel, a photo that isn't 1:1, 4:5 or 9:16, or a connection that needs reconnecting.

Captions

Write one caption and it goes everywhere. Under the box you'll see a running count of characters and hashtags, with buttons to copy or clear the caption.

• The YouTube title. A blank line splits the caption: everything above it becomes the YouTube title (capped at 100 characters) and everything below becomes the description. Instagram, Facebook and TikTok always get the whole caption. The line under the box shows exactly what YouTube will use.
• A different caption per platform. Tap Different caption per platform to give each platform its own box, for example different hashtags on TikTok.
• @ for handles. Type @ at the start of a word to pick from your saved people and every account you've mentioned, tagged or collaborated with before. Press Enter or Tab to insert one.
• / for snippets. Type / and a shortcut (like /tix) to drop in saved text such as a ticket link or your hashtags. Enter, Tab or Space inserts it.

Handles & Snippets

Your drummer is @drummerdude on Instagram but @drummerdude_official on TikTok, so which one goes in the caption? With handles, both: save a person once and BLASTR swaps in the right handle for each platform when the blast goes out. Open Handles & snippets from the sidebar's workspace section (on a phone, from your profile menu), or from the Manage handles and Manage snippets links under the caption.

The page has three tabs:

• Names aren't case-sensitive, and dots and underscores don't matter: @BowlingForSoup and @bowling_for_soup find the same person.
• Handles work in captions and in the YouTube title and description.
• Handles, snippets and posting times all belong to the workspace, so each band has its own.

Platform Settings

Tap a platform's row in the composer to open its options.

Length & Caption Limits

Each platform has its own rules. The composer's checklist flags anything that breaks one before you blast, so nothing fails as a surprise. The platforms that can take the post always still go out.

Photo Blasts

Photos work like videos. Add a JPG, PNG or WebP and blast it to Instagram, Facebook and TikTok. YouTube doesn't take photo posts, so it's switched off automatically.

Aspect ratios & the crop tool

Platforms want photos in 1:1 (square), 4:5 (portrait) or 9:16 (full-screen). If yours is something else, the checklist says Photo may get cropped and its Crop button opens the crop tool (also under the photo as Crop photo). Pick a ratio, then drag to position and pinch or scroll to zoom. Rule-of-thirds guides help you line up the shot, and BLASTR never stretches a photo beyond its real resolution.

Scheduling

Press the arrow beside the send button to choose when each video goes out:

Whatever you pick shows on the video's tile and on the button. Save your usual times under Handles & snippets → Posting times (the menu's Change link goes there too). Open slots skip times already taken by other scheduled posts, and roll into the next day when today is full. To batch a week of posts, add seven videos, pick Spread across your posting times, and you're done.

How each platform schedules

• YouTube & Facebook schedule natively on their own servers.
• Instagram & TikTok have no built-in scheduling, so BLASTR's servers hold your video and publish it at the exact time you chose. You don't need to be online.
• Facebook needs about 10 minutes' notice. Schedule something sooner and BLASTR moves only the Facebook post to the earliest time Facebook accepts. The card says so (Facebook needs 10 minutes' notice — this one posts at 3:11 PM). Your other platforms still go out on time.

Changing a scheduled post

• Edit opens the post in the composer, where you can change the caption, cover and settings, then Save changes.
• Reschedule moves it to a new time. This moves Instagram, TikTok and Facebook. YouTube holds its copy on its own servers, so change a YouTube time in YouTube Studio.
• Editing the caption of a scheduled or published post updates it on the platforms that allow edits. If a platform can't be updated (YouTube can't), BLASTR tells you which.

Your Posts & Drafts

Everything you've blasted lives on the BLASTR home screen, in four tabs:

The ⋮ menu on a post offers Blast again (a new blast with the same caption and settings), View in Content Library, Download video, Edit in YouTube Studio, and Retry for any platform that failed.

Add a platform to a post you already blasted

Forgot TikTok? No need to re-post everything. Open the post, switch the missing platform on, set its options, and save. BLASTR blasts only the new platform and leaves the rest untouched. The post stays one card with all its links.

Your blasts are kept

On Cadet, Voyager and Interstellar, every blast is saved to your Content Library in a category called Blasted, and kept for as long as it's there. That copy is what lets you retry a failed platform, add a new one, or blast the same clip again later, from any device. Blasting something that's already in your library doesn't make a second copy; it adds to that clip's Blasted 2× count instead.

If your library is full, or you've switched off Save blasts & BOOSTR videos here, a blast keeps a short backup instead: Cadet 1 day, Voyager 3 days, Interstellar 5 days, shown as a green Backed up · N days left chip. After that you'd need to re-upload the file to post it somewhere new.

On Rookie (free) there is no backup of a published video. As soon as every platform goes live, BLASTR deletes its copy, so download anything you want to keep from the ⋮ menu right after posting. A blast that fails is different: we hold that video for 7 days so you can retry it.

Notifications

Blasts run in the background, and scheduled posts can go live hours after you've closed the app, so BLASTR can tell you the moment a blast publishes.

1. Open Profile → Account Settings and find Notifications.
2. Press Turn On and allow notifications when your browser asks.
3. Press Send a test notification to confirm it works.

You'll get one notification per blast: published, partially published (some platforms worked, some didn't), or failed. That covers immediate blasts and scheduled posts that go live later.

Save as Defaults

Once a video's settings are how you like them (which platforms are on, YouTube visibility and audience, Instagram collaborators, tags and share options, TikTok privacy, all of it), press Save these as defaults under the platform rows.

• Every new video in that workspace starts with your defaults.
• Defaults are per workspace, so each band or brand has its own.
• Captions and locations are deliberately not saved, because those change with every post.

Content Library Paid plans

The Library tab is your band's media drive: every clip and photo you shoot, sorted the way you think about it, one tap from a blast or from BOOSTR. Add files with the + button or by dropping them anywhere on the page.

Finding things

• The left side is where things live. Recently uploaded (your newest 24), Videos, Photos and All media, then your categories. Categories can have one level of subcategories (Fall 2026 Tour › September, October), and opening a category shows everything in its subcategories too. Drag a card onto a category to move it; double-click a category to rename it.
• The right side is what you're looking for. The Filters panel has search, sort, Tags (match all or any), Shot by, Blasted, Shape, Length and Added, plus Clear all. Each choice shows how many items it would leave. On a phone, the same panel opens from the Filters button.
• Two views. The button at the top right switches between Preview (cards, Regular or Compact) and List, grouped by Category, Shot by, Month added, or not at all. Your choice is remembered on that device.
• Quick look. On a computer, press Space to open the card under your pointer (or the selected row), the arrow keys to step through, and Space again to close.

Using your media

• Each item's ⋮ menu has Send to BLASTR, Blast again, Send to BOOSTR, Quick look, Edit details… (name, category, shot by, tags, notes), Download and Delete.
• Select several items to Send to BLASTR, move, tag, download or delete them together.
• Credits. Everything you add is credited to the handle in Account Settings → Instagram handle, shown as @handle on the card. Change it in Edit details to credit someone else, like the photographer who shot it. A clip sent to BLASTR arrives with that credit already at the end of the caption, after a blank line, where you can keep or delete it.
• Saving to your iPhone. Download gets the file ready, then Save opens the iPhone share sheet so you can save to Photos or Files.
• Save blasts & BOOSTR videos here (under the categories) files every blast and every BOOSTR export in the library automatically, in the Blasted and BOOSTR categories. It's on by default and applies to the whole workspace.

Storage is pooled across your workspaces: 50 GB on Cadet, 200 GB on Voyager, 500 GB on Interstellar. The meter under the categories shows what's used. See Plans & Billing for what happens if a plan ends.

Sounds & Records Paid plans

The Sounds tab (the headphones) holds your music: albums, EPs, singles and loose sounds, with a player and pages you can share. Records are grouped the way a discography is: Albums, EPs, Singles, Mixtapes, Compilations and Live albums, then Loose sounds. Album art and List switch the view.

Making a record

• Drop the whole thing at once. Drag the audio files and the cover art onto the Sounds shelf together and they become one record: cover on, tracks numbered, titles read from the files.
• From sounds you already have. Select loose sounds and choose New album from N sounds…, or add them to an existing record.
• From scratch. Press New album.

BLASTR reads titles and the running order from each file's tags, or from filenames like 01 Neon Highway_MASTER.mp3, tidying up words like "final mix" and fixing ALL-CAPS titles. It never overwrites a title you typed yourself. Read the files again in the record's menu runs it again.

Inside a record

• Play and Shuffle play the whole record. On a computer, double-click a track to play it and click its title to rename it. On a phone, tap to play and rename from the track's ⋮. Drag the grip to reorder.
• Edit sets the title, artist, release type and date, genre, record label (printed as the ℗ line), cover art, liner notes and credits. Pick a role for each person, or + New role… for one of your own. Credits print together: "Mixed by Ari Lin and Dana Park".
• Add files adds tracks, or a new cover, from your phone or computer. Dropping files onto an open record does the same.
• Deleting a record keeps its tracks as loose sounds.

Sharing

Share… on a record (or Share this song… on a single track) gives you a link to a page with the cover, the player and the credits. Choose Public (anyone with the link) or Private (only signed-in people with access to your workspace), and turn Allow downloads on or off. Reset link makes a new link, and the old one stops working immediately.

BOOSTR — Make the Video Paid plans

BOOSTR is BLASTR's video editor. Drop in a clip and lay a tour poster, timed lyrics or captions over it, cut it together on the timeline, pick a look, and export a finished MP4 that goes straight into a blast. Open it from the BOOSTR tab, or send a clip from your Content Library with Send to BOOSTR.

What it costs

Making a video

1. Start. Press New BOOSTR video (or drop a clip anywhere on the page). MP4 and MOV both work, including video straight off an iPhone.
2. Choose what goes on it. Open Text and pick a tab: Tour Poster, Lyrics or Captions. New projects start blank, with a prompt in every field.
3. Pick a look. The Looks tab has thumbnails of every built-in look, painted with your mode's words.
4. Cut and style. Trim and split the footage on the timeline, add effects and text, adjust any block on the picture.
5. Export. Press the download button at the top right, name the video, and it renders.
6. Send it. Send to BLASTR drops the finished video into a new blast with no re-upload. Or Download MP4.

Find your way around

The toolbar holds Text, Captions, Timing (when the text comes in and goes out), Logo, Trim and Video (Change video…, with the choice to keep your look or start fresh). Text has seven tabs: Tour Poster, Lyrics, Captions, Looks, Font, Transitions and FX.

• On a computer (1024px and wider), the tools stay open in a panel on the right, and the picture never moves.
• On a phone, each tool slides up as a card. The picture stays the same size and the words lift above the card so you can still see them.
• Quick tools (top left of the picture) put sliders right on the block you've picked: block size, line spacing, text size, letter spacing, rotation and opacity. Drag a block to move it. Double-tap a block to open its settings.
• Safe zones (top right of the picture) overlays Reels, TikTok or Shorts' own buttons and captions, so you can see what they'd cover. Fit text inside pads your text into the safe area in one move. Guides are preview only and never appear in the export.
• Undo and redo sit beside the play button. The workspace switcher stays in the top bar, so you can change band without leaving the editor.

Tour Posters

The Tour Poster tab has six blocks: Headlines, Subhead, Tour dates, Legend, Footer and Layout. Tap a block's name to open it. Each one has its own on/off switch, colour, alignment, text size and a Style button.

• Headlines: add more than one and they take turns across the clip while the dates carry on underneath.
• Legend: an emoji and a band name per line (🎸 The Sun Machines), matching the emoji at the end of a date.
• Layout: how the dates move (below), plus row style (Columns or Stacked), the overall text size, line gap and tracking, padding, the export shape's crop, and a backdrop behind the words.
• ALL CAPS at the bottom of the tab capitalises everything when the video is drawn, without changing what you typed.

Pasting tour dates

One show per line. Columns split on tabs, |, - , — , or two or more spaces:

JUL 12 — BROOKLYN, NY — Baby's All Right
JUL 14 | PHILADELPHIA, PA | Johnny Brenda's
JUL 16   WASHINGTON, DC   Black Cat SOLD OUT

• One column becomes a single line, two become date + city, three or more become date + city + venue. Lines with no separators at all still work: 9/17 Pittsburgh, PA Thunderbird Music Hall.
• Ticket notes like SOLD OUT, LOW TICKETS, ON SALE, CANCELLED, POSTPONED, NEW DATE or JUST ADDED are recognised and hang at the end of that show's row instead of being read as the venue.
• A trailing emoji marks a support band and pairs with the Legend.
• Import CSV… on the Tour dates block (or drop a .csv/.tsv): columns are date, city, venue, status, emoji, with the last two optional. A header row is detected and skipped.

Layout modes

Style

Every block's Style button gives it its own Gradient, Stroke, Glow, Drop shadow and Extrude (a solid 3D side, with an optional Block outline around the whole shape). Apply to all copies one block's style to every block. Follow the look hands the block back to the current look.

Lyrics & Captions

The Lyrics and Captions tabs put timed lines on the video, one at a time. The tour poster steps aside while you're in either one and comes back when you return to Tour Poster. Lyrics and captions each keep their own words, timing and look.

Timing lyrics

1. Paste the words, one lyric line per line. A blank line is a line too: it clears the screen, which is how you leave room for a musical break.
2. Press Time the lyrics. The song plays; press TAP (or Space) as each line starts, and END (or E) where the screen should go empty. Your reaction time is taken off every tap automatically.
3. Fine-tune. Each line gets a pin on the film strip. Drag a pin to move its line, hold one still to zoom in for frame-exact timing, or use − / + on the line's row. Letting go of a pin plays from a second before it so you can hear whether it's right.

• Fix a typo by tapping the words in the list. The line keeps its timing.
• A line clears after (5 seconds by default) stops a line hanging on the screen through a long break. Lines it shortens are marked clears. Set it to 0 to turn it off.
• Each mode has its own Text size, alignment, line spacing and Nudge all to shift every line at once.

Generate Captions

On the Captions tab, Generate Captions listens to the speech in your edit and writes the captions, already timed. Everything after that works exactly like lyrics: fix any word, drag any pin.

• Only the sound of your edit is sent to our speech-to-text provider, never the picture. It isn't kept, and it isn't used to train anyone's AI.
• It reads the edit as you've cut it, so footage you trimmed out is never transcribed or charged.
• One run can be up to 15 minutes of audio. Your allowance is in What it costs, and the note after each run tells you what's left.
• Prefer to type them? Write one caption per line and time them with TAP, just like lyrics.

Looks, Fonts & Motion

• Looks. 33 built-in looks in three groups (Tour Poster, Lyrics and Captions), each shown as a thumbnail. Save look keeps your own; saved looks belong to your account, so they're on every device you sign in on. Each mode remembers the look it was wearing, so switching between Tour Poster, Lyrics and Captions never mixes them up.
• Font. 54 typefaces, from clean sans to hand-drawn, western and horror.
• Transitions. 17 entrances (Fade, Slide Up, Slide In, Punch, Drop, Blur In, Wipe, Typewriter, Glitch, Flicker, Tracking, Squash, Cascade, Wave, Scramble, Word Pop and Karaoke), each shown playing on its tile. The exit can match or differ, and In, Out and Stagger set the timing. Karaoke fills each line as it's sung; pick its Unsaid and Said colours.
• FX keeps words moving while they're on screen: Pulse, Float, Boil (a hand-drawn wobble), Neon breathe, Shimmer and Flames (pick the flame colour), with a strength dial.
• Logo. Add a logo (a PNG with transparency works best) and show it at the beginning, the end, or both, with its own size, position, transitions and FX. Hide dates while the logo is up gives the logo the frame to itself; turn it off to keep the logo up as a watermark.

The Timeline

Under the picture, the timeline shows your footage as a film strip. Pinch or ⌘-scroll to zoom. Tap the strip to pick the footage up: yellow handles appear at each end to trim it, and a toolbar shows what you can do to it.

• Cut it up. Split cuts at the playhead, and the left half stays selected, ready to delete. Shots can be copied, pasted, duplicated, deleted and slipped (moving which part of the footage plays without changing the shot's length). The track closes up behind every cut.
• Effects & filters. Effects (Shake, Pulse, Push in, Pull out, Sway, Flicker, Glitch), Filters (Mono, Noir, Warm, Cool, Vivid, Faded, Bleach, Night, Crush) and Opacity lay an effect clip on its own lane above the footage. Drag or stretch it across as many shots as you like, and use Strength to dial it in. Stack adds another lane above it.
• The + at the end of the strip adds Text (words on the picture, with their own font, colour and style), or a photo or video overlay.
• On a computer, drag a clip to move it. On a phone, press and hold a clip first, then drag.

Exporting

1. Press the download button at the top right. Name this video is filled in for you; the name becomes the file name and the Content Library title.
2. A progress bar shows the render, with Cancel.
3. Your video is ready: Send to BLASTR, Download MP4, and the Content Library button. It reads Saved to Library when the video was filed automatically, or offers Save to Library when it wasn't. ← Back to the editor keeps working on the same video.

The chip beside the download button (it reads HD, 2K or 4K) holds the export settings:

• Shape: match source, 9:16, 4:5, 1:1 or 16:9 (move the crop under Tour Poster → Layout).
• Frame rate: match source, 24, 30 or 60 fps. Resolution: match source, 720p, 1080p, 1440p or 2160p (4K).
• Quality is automatic, picked from the size and your source's own quality. There's no bitrate slider on purpose: the only thing a manual setting could do is make your video worse.
• Keep source audio carries your clip's sound. If BOOSTR can't carry a clip's audio, it says so when you open the clip, not after the render, and asks before you send a silent video to BLASTR.
• Save to Library files every export in the Content Library's BOOSTR category. It's the same switch as the library's Save blasts & BOOSTR videos here, on by default for the whole workspace.

Your videos

Finished exports are listed under Your videos on the BOOSTR home screen. Each card has Send to BLASTR, a status chip (Saved in your Content Library, Backed up · N days left, or On this device only), and a ⋮ menu with Download, View in Content Library, Reopen look and Delete.

• Every video is kept on the device that made it, so playback and download are instant.
• On Cadet, Voyager and Interstellar it's also saved to your Content Library (when Save to Library is on), so it's on every device. Otherwise its cloud backup lasts 1, 3 or 5 days, depending on your plan.
• On Rookie, a video lives only on the device that made it. Download the MP4 if it matters.

Workspaces & Teams

Workspaces

A workspace is a complete, separate identity: its own connected socials, posts, drafts, defaults, handles, snippets, Content Library and Sounds. Manage one artist on Rookie or Cadet, up to 5 workspaces on Voyager, or 10 on Interstellar, perfect for managers running several acts.

• Switch workspaces from the bar under the top of the screen. Everything on screen switches with it, in BLASTR and in BOOSTR.
• Rename, create or delete workspaces from Manage workspaces (in the sidebar's workspace section, or your profile menu on a phone).

Teams Voyager+

Share a workspace so a bandmate, editor or manager can post for that act, and only that act.

1. Open Manage workspaces and find the workspace's Team.
2. Choose Invite by email, enter their email, and pick Can edit (upload and blast) or Read only (view).
3. Press Send Invite. The invite is pending until they accept it from the email. They don't need a BLASTR account first; they can sign up from the link.

They get your plan inside your workspace. A teammate works at the level of whoever owns the workspace, so everyone you share with gets your Content Library (it counts against your storage), your backup window and Save draft in that workspace, even on a free account. Their blasts and BOOSTR videos there don't count against their own limits. Their own workspaces stay on their own plan.

Security & Appearance

• Two-factor authentication. Under Profile → Account Settings, turn on 2FA and BLASTR emails you a 6-digit code whenever you sign in.
• Appearance. Pick a theme: Blastr Neon, Blastr Light, Boring Monday, MySpace Classic, MySpace Coded, Windows 95 or Macintosh.
• Take the tour. The help menu in the sidebar replays the quick tour of BLASTR, and links back to this page.

Plans & Billing

BOOSTR is included on every paid plan. Rookie gets 4 to try in the first 30 days; see BOOSTR for how they're counted and for the Generate Captions allowance.

Content Library and Sounds come with every paid plan: 50 GB on Cadet, 200 GB on Voyager and 500 GB on Interstellar, shared across all your workspaces. We email you when it's 90% full so you can clear things out or move up a plan. Nothing in it expires while your plan is active. If your plan ends, the library turns read-only for 30 days so you can download everything, and after that it's removed from our servers. Renew within those 30 days and nothing is lost. Moving to a smaller plan never deletes anything; new uploads just pause until you're under the new limit.

Upgrade, downgrade, or manage your card any time from Profile → Billing. Payments are handled securely by Stripe.
