00:00 Windows desktop app

Your VOD has the highlight.
InkBurst finds it in seconds, not hours.

Drop in a stream or recording and InkBurst detects the Clutch, Epic, Chaos and Finish moments on its own — then cuts Shorts, Highlight Reels and beat-synced Montages ready to publish.

Docs & setup

Getting started

  1. Install InkBurst and open it — it's a standalone .exe, nothing else to set up to start cutting Shorts.
  2. Drop in a VOD. Any length works; very short clips automatically use a finer detection window so the tone pills still find distinct moments.
  3. Run detection, then scrub each candidate in the preview and hit Set Start Point if you want the clip to begin at an exact frame instead of the auto-detected one.
  4. Export, or move into Montage/Highlights if you're on a tier that includes them.

Connecting YouTube

InkBurst uses a "bring your own API credentials" model for publishing — the same pattern Google requires of any desktop app that uploads on a user's behalf. This keeps your uploads tied to your own Google account, with no shared key and no InkBurst-run server in the middle.

Set it up once

  1. Create a free project in Google Cloud Console and enable the YouTube Data API v3.
  2. Create an OAuth client of type Desktop app, then download its JSON file.
  3. In InkBurst, go to Settings → YouTube and click Import Client Secret JSON — pick the file you just downloaded.
  4. Click Connect YouTube and sign in. You're done — InkBurst remembers the connection.
No Google OAuth client file found This means step 2–3 above hasn't happened yet — it's not related to your API project being in Testing vs. Production. Use the Import button in Settings to fix it in one click.

Publishing checklist

A couple of things are easy to miss the first time:

Treat as Short Ticking "Treat as Short" now auto-selects YouTube for you — you no longer need to separately tick the platform checkbox for it to actually upload.
Why didn't my upload land in Shorts? YouTube decides Shorts vs. regular Videos purely from the clip's own duration (≤3 min) and aspect ratio (vertical or square) — not from the Shorts tag. InkBurst checks this before uploading and will tell you exactly which condition a clip fails, so you can re-render it instead of it quietly landing in Videos.

FAQ

Does InkBurst collect any of my data?

No. The only automatic network call it makes is to verify your Patreon tier/license key — no analytics, no tracking, nothing running in the background. Detection and rendering happen 100% locally with ffmpeg. The only other outbound calls are ones you trigger yourself — your own YouTube/TikTok upload, or AI Tag Gen's call to Anthropic using your own key. Nothing goes anywhere unless you click the button that sends it.

Windows Defender flagged the installer — is this safe?

Yes — it's a false positive, and a common one. InkBurst is built with PyInstaller, which packages a full Python runtime into one executable; unpacking a bundled runtime at startup looks behaviorally similar to how malware droppers work, even though nothing hidden is going on. The app also isn't code-signed yet (an individual certificate now runs £300–500+/year) and is new enough to have no SmartScreen reputation built up. If Defender blocks the install, click "More info" → "Run anyway," or add an exclusion for the folder. Signing is on the roadmap once the Patron base can support the ongoing cost.

Why is a long VOD slow to upload or render?

Expected for very long sources — a 2hr+ VOD takes longer to upload into the app, and anything 5+ minutes takes longer to render (depending on your machine). The app hasn't hung, it's just working through more footage. A ~30-minute VOD uploads noticeably faster.

Can I use this on more than one PC?

Each Patreon pledge includes one license per device. If you need it on a second machine, that's a separate license.

What happens if I cancel my pledge?

The app keeps anything you've already rendered. Features above your remaining tier (or all features, if you cancel entirely) lock again until you resubscribe.

Why does a 1-minute clip behave differently from a 10-minute one?

Moment detection scales its analysis window to the clip's length, so even a very short source still gets genuinely distinct Clutch/Epic/Chaos/Finish picks instead of the same timestamp repeated under different labels.

User manual

The full walkthrough, tab by tab, with real screenshots from the app.

Getting Started

Installing. InkBurst Auto Shorts is a Windows desktop app. Download and run the installer you get access to through Patreon — no separate setup needed beyond that.

Logging in. Click 🔑 Login with Patreon in the top-right corner. This opens your browser to Patreon — log in there if you haven't already, then approve the InkBurst Auto Shorts access request (your email, Patreon identity, and pledge info). A "Login complete!" page confirms you can close that tab; switch back to the app and the button updates automatically to show your active tier.

Patreon access request

Patreon's access request — review it, then Allow.

Login complete confirmation page

"Login complete!" — close the tab and switch back to the app.

If login doesn't finish within about two minutes, the button resets to Login with Patreon — just try again.

Tiers. Your Patreon pledge unlocks features cumulatively — each tier includes everything below it. A locked tab shows a lock icon and a short note on which tier unlocks it — click it to jump to Patreon.

The five tabs, top to bottom: ✂️ Shorts Creator (your main vertical-clip tool), 🎨 Layout Editor (fine-tune your 9:16 crop — any paid tier), 📝 Montage, 🎥 Landscape, 🖼️ Thumbnail Creator.

Shorts Creator

This is where you turn a VOD into a batch of vertical (9:16) Shorts. The sidebar has three stacked groups: Source File, Setup, and Generate.

Source File

Drop a VOD onto the dropzone, or click to browse. If you've used this VOD before (or it's already on the server), you'll see "already on server, no upload needed" or "local file, instant" instead of an upload step — a brand-new VOD still gets copied to your Uploads Folder first, with its own progress stage, before analysis starts.

Source File dropzone

The Source File dropzone.

Setup — Trim

  • Trim start / end (h:mm:ss) — cut the VOD down before any analysis runs.
  • Resolution — 640p Draft, 720p, 1080p (default), 1440p, 4K, or 8K.
  • Quality — Draft (fast), Balanced, or High (default).
  • Mix background music (beat-synced) — on by default.
  • Mute gameplay audio — strips the original audio entirely.
  • Game audio / Music sliders — relative volume mix (defaults 70% / 50%).
Trim, Quality and Audio panel

Trim, Resolution, Quality, and the audio mix.

Setup — Music

Point at a Music folder (the app scans it and auto-matches a track to each clip's energy) or set one exact track to use every time.

Music folder picker

Pointing the Music folder.

Setup — Layout

Apply a saved Layout Preset (built in the Layout Editor tab) to control how game/cam footage is cropped into the 9:16 frame.

Layout preset picker

Applying a saved Layout Preset.

Generate — Shorts

  • Clip Length Mode — Fixed, Up To, or Between.
  • Num shorts — 1–30 clips, default 5.
  • Tone / Energy Mode — Hype, Chill, Varied, Clutch, Epic, Chaos, Late Game, Finish, or Random.
  • Smart stop point — nudges a clip's end to a nearby quiet moment instead of a hard cut.
  • Clip Effects Full tier — Speed Boost, Zoom In, Flash, Shake.

Hit ▶ Process VOD to start, or ⏹ Stop Generation to cancel mid-render. Finished clips land in the Generated Clips grid below.

Highlights Reel & Manual Stitch £17.99+

Still inside Shorts Creator's Generate group, two more tabs sit beside Shorts.

Highlights

Builds one longer 9:16 reel instead of several short clips, analysed independently of your Shorts settings.

Highlights Reel panel

The Highlights Reel panel.

  • Tone pills (same set, minus Varied).
  • Clips in reel (2–30, default 8) and Secs per clip (1–120, default 5) — live total reel length readout.
  • Clip Distribution Zones — split the VOD into 2, 3, or 4 zones so clips are pulled evenly across the whole video.
  • 📌 Lock first/last clip, 🔀 Random mix, 🎯 Cut to the Beat (needs music on).

Hit 🎬 Generate Highlights.

Stitch

Manually glue clips you've already rendered into one reel, in whatever order you pick.

Re-render Clip dialog

The Re-render Clip dialog.

Layout Editor

Available to any paid tier. This is where you tell the app how to crop your game footage and webcam into a 9:16 frame — and save that as a reusable preset other tabs can apply.

  • Crop boxes: Game, Cam, Extra 1 (e.g. a chat box), Extra 2.
  • Split slider (30–90%, default 70/30) — vertical space for game vs. cam.
  • Presets — Default, Big Cam, Small Cam, or your own saved layouts.

Getting a frame to work from

Either Grab Frame from VOD — pick a video, type a timestamp, click Grab This Frame — or Load Screenshot to drag a file in directly.

Analysing and picking clips

Set Moments to find, Clip length, and Trim start/end — a live Total readout updates as you adjust. Click 🔍 Analyse VOD first — this is required before you can render.

Clip Settings panel

Clip Settings, including the Trim fields and live Total readout.

The Detected Moments list shows each clip's thumbnail and timestamp, with Start/Dur fields you can nudge, a per-clip Cut transition dropdown, and a preview button. Scrub the preview to the exact frame you want, then hit 📍 Set Start Point Here to lock a clip's start to that exact point instead of the auto-detected one.

Detected Moments and Generated Montages results

AI Tag Gen £34.99

AI shows up in two places once you're on the top tier — metadata for Publishing, and layout suggestions for Thumbnail Creator. Neither one touches your clip or your render until you review it.

Metadata — in the Publish Clip modal

Open Publish on any clip, then use the Tell the AI about this clip box to give it context — a line like "this is the boss fight at the end" or "keep it low-key, not hype" — before hitting ✨ Generate with AI. It fills in the Title, Description, and Tags fields for you, which you can still edit by hand before you hit Publish.

Publish Clip modal with AI metadata generation

The Publish Clip modal — Tell the AI about this clip, then Generate with AI fills Title/Description/Tags.

Thumbnail layouts — in Thumbnail Creator

On the Overlays & Text step, the AI Suggestions panel looks at the frame you've picked and proposes overlay text and color settings to match it. Add a line in Tell the AI about this image — e.g. "this is the final boss kill, want it hype" — and hit ✨ Generate with AI. Nothing is applied to the export until you review the suggestion and hit Export yourself.

AI Suggestions panel in Thumbnail Creator

AI Suggestions — proposes overlay text and color settings from the frame; you review before exporting.

Before you start AI Tag Gen needs your own Anthropic API key, added once under Settings → AI metadata — see the Settings section below.

Logo Watermark

Upload a logo once and it's baked into every new Shorts, Highlights, Montage, Stitch, and Landscape (Highlight Reel/Intro + Outro) render automatically — re-rendering an older clip reapplies it too. Swap the file any time to change it everywhere at once.

Logo Watermark panel

The Logo Watermark panel, with separate 9:16 and 16:9 previews.

  • Enabled — turn the watermark on or off without removing the uploaded file.
  • Upload logo… / Remove — swap or clear the active logo image.
  • Two live previews — Shorts / Highlights / Stitch (9:16) and Montage / Landscape (16:9) — so you can see exactly where it lands on each aspect ratio before rendering anything.
  • Position — pick a corner: top-left, top-right, bottom-left, or bottom-right.
  • Opacity — 0–100%, default 85%.
  • Size — a percentage of video width, default 35%.

Click Save to apply it everywhere, or Close to discard changes.

Settings

Open via the ⚙ Settings button in the header.

Settings panel

The Settings panel.

Theme

Seven complete visual restyles — Dark, Light, Fun, Bubbly, Nova (the default), Brutal, Glass. Click a swatch to apply it instantly; your choice is remembered.

Rendered Videos Folder

Where finished shorts, highlight reels, montages, and outros are saved after rendering. Point this at a folder you can easily find and clear out when you want to free up space.

Uploads Folder

Where source VOD files are copied before processing starts. Point this somewhere with enough free space for your raw recordings.

Changing a path Only affects new files going forward — anything already saved in the old folder stays there and won't be moved automatically. Delete or move old files yourself if you want to clean up.

YouTube

Connect the channel clips get published to. Needs a one-time Google OAuth client (see Connecting YouTube above) — then a one-time Google sign-in in your browser. Use Import Client Secret JSON to pick your credential file, then Connect YouTube to sign in.

TikTok

Authenticated separately — run tiktok_auth.py once from a terminal to connect. Posts from this app are private (only visible to you) until it's been through TikTok's own app audit — that's a TikTok restriction, not something InkBurst controls.

AI metadata (Anthropic API key)

Used to generate a clip's title, description, and tags on demand. This is your own key, billed to your own Anthropic account — get one at console.anthropic.com. Paste it in and hit Test key to confirm it works right now, then it's saved for every AI Tag Gen call from then on.

Why "Test key" instead of a balance check Anthropic doesn't offer a way to check a personal key's remaining balance from inside an app like this one — only an org-level Admin key can see historical spend, which this app has no business asking you for. Test key sends one real, tiny request to confirm the key works and has credit behind it, for a near-zero cost. To see or top up your actual balance, go to console.anthropic.com → Billing. A title/description/tags generation costs a small fraction of a cent per clip — see anthropic.com/pricing for current rates.

This feature calls the Anthropic API directly using the key you enter above. InkBurst Ltd is not affiliated with, sponsored by, or endorsed by Anthropic; "Claude" and "Anthropic" are trademarks of their respective owner.

Tips & Tricks

  • Reuse your Layout Preset everywhere. Build it once in Layout Editor, then pick it in Shorts Creator, Montage, and Landscape.
  • Trim dead air before you analyze. Cut loading screens and menus before the app scans for moments.
  • Don't worry about re-uploading. A VOD processed before is recognised and skips straight to analysis.
  • Changed Montage's zone pills? Re-analyse. Switching zones flags settings as changed but won't re-scan on its own.
  • Mix weights don't need to add up to 100. They're just relative ratios.
  • Scan once, reuse forever. Star good frames in Thumbnail Creator's Saved Frames tab.
  • Cut to the Beat needs music on. It's a transition style, not a standalone toggle.

Troubleshooting

App window never opens, no error shown You likely need the Microsoft Edge WebView2 Runtime. Windows 11 ships it built-in; on Windows 10, download the WebView2 Runtime installer from Microsoft directly if it hasn't arrived via Windows Update.
A tab shows a lock icon You're not on the Patreon tier that unlocks it — click the lock badge to see which tier you need.
A render fails partway through Check the log box under the progress bar for the actual error text. If it's unclear, note the exact wording and when it happened before reaching out for help.
Montage's zone pills seem to give the same clips either way Make sure you click Re-analyse VOD after changing zones — switching a zone pill doesn't re-run analysis on its own.

If something still doesn't make sense, message on Patreon with: which tab you were on, what you clicked, and the exact text of any error message or log line.
