Ask, and Claude now builds 3D scenes too. Alongside flat titles and diagrams, you can bring depth into your video with words alone.
NewClaude can build 3D animations with three.js: extruded lettering (Japanese included), logos, shadows, glow and camera moves
NewMore GSAP effects to ask for: long captions, cards, re-sorting rankings and roulettes that spin to a stop
ImprovedMore reliable Claude integration: Claude can check its work with images in Safari too, fonts stay correct in text-heavy Japanese animations, and older extensions are told when a new version is available
Animations Claude makes with GSAP now look better. Claude checks frames as images and refines them before creating the clip, and you can ask it to revise a finished one — "change the colors," "make it 2 seconds longer."
ImprovedIn GSAP animations, Japanese fonts, counting numbers and letter-by-letter effects now render correctly, and long renders no longer get cut off
NewAsk Claude to revise an animation it made. Split clips are all updated together, and a single Undo brings back the previous version
ImprovedClips on higher tracks now appear in front in the preview and export (existing projects look the same)
FixedMoving a clip or changing its speed no longer shifts other clips
FixedMore reliable exporting and saving: linked audio is no longer doubled, and edits made right before closing the tab are saved
ImprovedStorage files for media you no longer use are now cleaned up automatically, saving disk space
VideoBuff now loads about 70% less data when you open the site or the editor, so pages appear faster.
ImprovedOpening the home page, guides, or the editor now loads about 70% less data, so they appear faster
FixedIn English, the export and Claude connection screens, error messages, and the "page not found" page now appear in English
FixedSwitching a text's font no longer briefly shows a different font
VideoBuff now works in Safari 26 or later on Mac. In every browser, exports are now less likely to fail: if your computer can't use a format, VideoBuff automatically switches to one it can. Importing media and the timeline display have also been improved.
NewSafari 26 or later on Mac now supports everything from importing to editing and exporting (auto captions require Chrome or Edge)
ImprovedIf your computer can't use a format or save location, exports now automatically switch to one that works
FixedMedia restored with Undo after being deleted now exports correctly
ImprovedYou can now drop files anywhere in the editor to import them
FixedVideo files without a video track (such as audio-only MP4s) are now imported as audio
FixedTimeline thumbnails now display correctly after you change a clip's length
You can now export videos with audio on Chromebooks and similar devices, and exporting also works in Firefox. Projects that use WebM or MKV videos, including screen recordings, can now be exported too.
FixedVideos with audio can now be exported on Chromebooks and similar devices
NewExporting now works in Firefox
NewProjects that use WebM or MKV videos, including screen recordings, can now be exported
FixedSome video formats now export correctly instead of coming out black
ImprovedVideos in formats the browser can't open (such as AVI) are now flagged when you import them
Zooming is now faster and lighter, even on long timelines. Memory use during exports and after removing media is also lower, and the Claude integration is more reliable.
ImprovedFaster zooming on long timelines, with lighter clip moves and trims
ImprovedLower memory use during exports and after removing media or resetting a project
FixedResuming playback with keyboard or headphone media buttons now correctly updates the playhead and play button
ImprovedMore reliable Claude integration: clip positions you adjusted in the editor are handled correctly, and preview images and bulk edits respond more efficiently
Importing and exporting large media is now faster and uses far less memory, and working in the timeline and Inspector feels lighter. Claude can now use the media you imported in the editor and check its edits by viewing preview images.
ImprovedFaster import for large videos with much lower memory use; thumbnails and waveforms also appear sooner
ImprovedFaster exports — up to about 30x faster for videos with color grading or perspective correction, and almost no wait before an export starts
ImprovedSmoother timeline scrolling and zooming, clip moves and trims, and Inspector edits
NewWhen the export frame rate is higher than your footage, the Export dialog now notes that motion won't get smoother — only export time and file size increase
NewClaude can now work with media you imported in the editor, look at preview images to check its edits, and import files by path
ImprovedClaude integration tool definitions use about 15% fewer tokens, and the connection is more stable
Your export settings now carry over to the next export. With "Cut here" in the right-click menu, a line shows exactly where the cut will be made. We also improved export quality for scaled-up clips and the quality of timeline thumbnails.
NewExport settings (resolution, frame rate, codec, quality, loudness) are remembered and reopen with the same values next time
New"Cut here" in the right-click menu now shows a line at the cut position
ImprovedScaled-up clips now export sharply
ImprovedHigher-quality timeline thumbnails, and clips created by a cut now show frames from their own section
We added "Auto" to the audio settings — it analyzes the clip's audio and applies a gentle EQ and compressor adjustment. We also improved how the preview and timeline look when a project has many tracks.
NewAdded "Auto" for audio — it analyzes the clip's audio and gently adjusts EQ and compression; fine-tune with each slider afterward
NewDragging a clip up or down now auto-scrolls the timeline vertically at its edges
ImprovedText in the preview now keeps the same proportions as the export, whatever the window or preview size
ImprovedAdding tracks no longer makes the timeline grow until it squeezes the preview; with many tracks, the timeline scrolls vertically
FixedEQ and compressor settings now apply to a video's built-in audio during preview playback
We moved color grading (saturation, sharpness, and more) to WebGL, dramatically speeding up exports that use it, along with faster exports for clips with subtitles or text and for timelines that reuse the same audio asset in multiple places. We also added vertical/horizontal keystone correction to the Transform panel — perspective correction similar to photo-editing apps — and text clips now show the same center-alignment guide as images and video when dragged.
ImprovedMoved color grading (saturation, sharpness, and more) to WebGL for dramatically faster exports
ImprovedFaster exports for clips with subtitles or text (layout calculations are now cached)
ImprovedFaster exports when the same audio asset (e.g. background music) is used in multiple, non-adjacent places
NewAdded vertical/horizontal keystone correction to the Transform panel — perspective correction similar to photo-editing apps
NewText clips now show the same center-alignment guide as images and video when dragged
We added "Auto" to the color tools — one tap analyzes the clip and applies an optimized color adjustment. We also fixed subtitle generation to show real model-download progress and to work correctly for audio-only clips, and reworked the timeline zoom bar so zooming feels smooth and lands where you aim.
NewAdded "Auto" to the color tools — it analyzes the clip and automatically optimizes brightness, contrast, saturation, and more. Pick it like any preset, and fine-tune afterward with the sliders
FixedFixed subtitle generation appearing stuck at "preparing audio 100%" while the model was downloading — it now shows real download progress
FixedFixed audio-only clips (WAV / M4A) producing garbled or empty transcriptions
ImprovedImproved the timeline zoom bar — the handle now tracks your cursor precisely, fine control and both zoom directions feel natural, and you can double-click the bar to fit the whole timeline
ImprovedCtrl/⌘ + wheel zoom now zooms in and out centered on the cursor
Master volume is a preview-only volume control, independent of each clip's own volume and export output. Adjust it anytime from the speaker icon in the transport bar — your setting is remembered. We also added a "Search commands" button in the header, so the ⌘K/Ctrl+K command palette can now be opened with a click too, plus an M key shortcut to toggle mute.
NewAdded master volume for preview playback — independent of each clip's own volume and does not affect exported output
NewAdded a "Search commands" button in the header — click it to open the command palette (⌘K)
NewAdded an M key shortcut to toggle mute
Clicking anywhere on the timeline while playback is running now moves the playhead there, instead of appearing to do nothing. In the preview, content that overflows the export frame after scaling a clip up is now hidden entirely instead of showing faintly outside the frame — selection handles still extend past the frame edge, so repositioning stays just as easy. Timeline track sizing is smoother when resizing the panel, and empty-track auto-removal now covers video/audio tracks as well as text/image. We also fixed an issue where playback could freeze or jump back to the start of that same clip instead of advancing to the next one. We've also cut stutter in several places — dragging clips during playback, zooming, resizing panels, and how quickly thumbnails and waveforms appear after reloading the page.
NewYou can now click anywhere on the timeline to seek there even while playback is running
ImprovedContent that overflows the export frame after scaling a clip up is now hidden instead of shown faintly — selection handles still extend past the frame so repositioning stays easy. When a clip is scaled down, the export frame boundary is now clearly visible against a gray background
NewResizing the timeline panel taller now scales track height proportionally, making thumbnails and waveforms easier to see
ImprovedEmpty-track auto-removal now also applies to video and audio tracks
FixedFixed playback sometimes freezing or jumping back to the start of that same clip instead of advancing to the next one
ImprovedReduced UI stutter during timeline operations (playback, dragging/trimming clips, zooming, resizing the panel)
ImprovedSignificantly reduced the wait for timeline thumbnails and waveforms to appear after reloading the page
Dragging an image or video clip in the preview now snaps to the frame center with horizontal/vertical guide lines, just like Google Slides (hold Alt to disable snapping). Also improved thumbnail rendering for vertical/square video, reworked the waveform renderer to better reflect the actual audio, fixed a couple of bugs when dragging images around, and added per-asset deletion in the Media Browser.
NewCenter-alignment guides while dragging in the preview — image and video clips snap to the frame center with horizontal/vertical guide lines, just like Google Slides. Hold Alt to temporarily disable snapping
ImprovedImproved timeline thumbnails — vertical, square, and other non-16:9 video now renders center-cropped without distortion, at a sharper resolution
ImprovedOverhauled waveform rendering — switched from peak-only to an RMS-based analysis so the shape actually reflects volume changes and beats, at higher time resolution and with a taller audio track
FixedFixed images layered over a video clip jumping to the wrong position when dragged instead of following the cursor
FixedFixed playback starting on its own right after repositioning or resizing an image
NewYou can now delete individual assets from the Media Browser — assets still in use on the timeline are protected from accidental deletion
Toggle "Place as karaoke captions" in Auto Caption to generate captions that highlight each word as it's spoken. Both preview and exported video include the karaoke effect. Pick from Classic / Pop / Glow / Bar styles and set a dedicated accent color per clip.
NewNew karaoke-captions mode in Auto Caption — each word lights up as it's spoken
NewFour karaoke style presets — Classic (sung words stay colored) / Pop (active char briefly enlarges) / Glow (accent-colored halo on the active char) / Bar (a progressive underline under sung words)
NewInspector exposes dedicated karaoke fields (accent color / style preset) — set once at generation time, fine-tune per clip
Generate captions automatically from any video or audio clip and drop them onto the timeline as text clips. Transcription happens entirely in your browser — audio never leaves the device. Japanese and English are supported, with optional translation of Japanese audio into English captions. See the auto-captions guide for details.
NewAuto-generate captions from any video or audio clip and place them on the timeline as text clips
NewChoose between Fast and High Quality models. Models are downloaded once into the browser cache and run offline thereafter
NewTranslate Japanese audio into English captions — pick "Translate to English" in the subtitle-language selector
NewLive preview of captions as inference progresses, inline text editing, and SRT / VTT / TXT downloads
Added a Cmd+K (Ctrl+K on Windows/Linux) command palette and a ?-key cheatsheet listing all keyboard shortcuts. Type what you want — like "cut", "split", or "undo" — and run it straight from the keyboard without hunting through menus.
NewCommand palette (Cmd+K / Ctrl+K) — type to run any timeline action, tool toggle, or playhead jump
NewKeyboard cheatsheet (`?` key) — every available shortcut grouped by category
Short animated clips (up to 30s) — fading-in titles, word-by-word kinetic typography, lower thirds — can now be added to the timeline by simply asking Claude in chat. Not intended to substitute for After Effects-level work; see the Animations by Claude guide for capabilities and limits.
NewClaude can now build animated clips and place them on the timeline — prompts like "a 3-second opener with the title flying in from the left" produce a usable animated clip in place
NewPre-check mode for animation prompts — iterate on variations before any encoding, catching issues like text overflow or empty animations cheaply
Reworked the tool schemas around Anthropic's MCP best practices, making Claude operating VideoBuff noticeably faster end-to-end.
