YouTube-ready editor # YouTube Video Editor Online 1920x1080No uploadPrivate YouTube expects 16:9 landscape at either 1920x1080 or 4K. The platform's ingest pipeline re-encodes every upload to a standard set of resolutions on the server side, so the goal when editing is to hand YouTube a clean high-bitrate source in the right aspect ratio and let the server-side encoding handle the rest. ## Project picker Multi-track editing with WebCodecs · Frame-accurate seek · Source monitor ### New Project ## About YouTube Video Editor Online The reason to edit in the browser rather than uploading raw footage straight to YouTube and using its built-in editor is the browser gives you a real timeline. YouTube's own editor is limited to trimming, cuts, and basic transitions on already-uploaded videos. Anything involving multiple clips, B-roll, text overlays, or precise frame-accurate in/out points needs a real editor before the upload. Doing that in VidStudio rather than a cloud editor like Kapwing or VEED keeps the raw footage on your device until you decide to publish. For unreleased trailers, tutorial recordings under embargo, interview footage where the guest has not yet approved publication, or anything corporate-confidential, the no-upload architecture avoids a meaningful category of risk. Click New Project to start a 1920x1080 timeline. ## When to use this editor #### Longform tutorial edits Cut an hour-long screen recording into a 12 minute tutorial with multi-track B-roll and text overlays, then upload the finished MP4 to YouTube. #### Vlog assembly Merge a week of clips into a single vlog episode. Frame-accurate seek picks exact edit points, multi-track handles music under voice-over. #### Channel trailer production A 60 second trailer cut from highlights across the channel. Works well in the browser and stays private until you upload to YouTube. #### Shorts from longform Pull a 45 second highlight from a longform episode, keep it at 1920x1080 landscape, then use VidStudio's resize tools to create a 9:16 Short version. #### Podcast-to-YouTube repurposing Convert a podcast audio file into a YouTube video with a static image or a talking-head camera angle, both browser-local. ## How to Edit a Video for YouTube in Your Browser #### 1 Click New Project Opens a 1920x1080 landscape timeline ready for source footage. #### 2 Drop your footage onto the source bin Drag clips into the bin. Mark in and out points against the source monitor before placing them on the timeline. #### 3 Edit and arrange the timeline Cut, rearrange, add B-roll on a second track, overlay text, apply transforms. #### 4 Export to 1080p or 4K MP4 Final MP4 saves to your device. Upload it to YouTube Studio as a normal video upload when the edit is done. ## Frequently asked questions ### Can I edit YouTube videos in my browser? Yes. VidStudio runs in any modern browser and handles multi-track editing for YouTube-ready 1920x1080 or 4K output. The raw footage stays on your device; you only upload to YouTube when you publish. ### What resolution should I export for YouTube? 1920x1080 at 60 fps is the safe default for most YouTube content. 4K (3840x2160) is worth it if your source is 4K and your audience skews toward large screens. YouTube transcodes every upload anyway, so export at the highest quality your source justifies. ### Can I edit long YouTube videos in the browser? Yes, up to the RAM limit of your device. A modern laptop handles 30 to 60 minute 1080p edits comfortably. For feature-length content, a desktop app like DaVinci Resolve or Shotcut may still be the better fit because it can page memory to disk more aggressively. ### Is there a file size limit on exports? No arbitrary cap. The practical limit is browser memory, which caps longform 4K edits before 1080p edits. YouTube's own upload limit is 256 GB per video, which is beyond what the browser can produce in one pass anyway. ### Does VidStudio have the YouTube editor's blur and end-screen features? No. YouTube Studio has specific features (auto-blur faces, built-in end screen authoring) tied to its platform. Export your edit from VidStudio as an MP4 and then apply those features inside YouTube Studio as a second step. ### How do I add captions for YouTube? Upload the MP4 to YouTube first, then use YouTube Studio's auto-caption tool or upload an SRT file you authored separately. VidStudio does not generate captions today; the recommended workflow is to let YouTube's caption generator run on the final MP4 after upload. ## Your video never leaves your device All processing happens locally in your browser, and your files never leave your device. The editor reads your video file through a standard browser file input, holds the bytes in memory, processes them in a Web Worker against WebCodecs and FFmpeg WASM, and writes the final MP4 back to your disk. No upload, no cloud rendering, no external copy. ## Related Tools and Resources #### [Resize for YouTube Shorts](/resize-video-for-youtube-shorts) Quick 9:16 1080x1920 resize for Shorts variants of your longform edit. #### [Trim video](/trim) Quick trims without loading the full editor. #### [Compress video](/compress) Reduce file size if your upload is timing out. #### [Video editor](/video-editor) The general editor landing. --- Source: [https://vidstudio.app/video-editor-for-youtube](https://vidstudio.app/video-editor-for-youtube)
