Local WebM export
Canvas, Web Audio and MediaRecorder assemble the output on your device.
Bulk-ready intake
Open multiple source clips together and apply one crop mode across the batch.
Important browser warning
Your source files live only in this tab. Do not refresh or close it before exporting, or the current media session will be lost.
Before you export
Build a reliable browser editing workflow.
Organize source clips
Use clearly named files and place them in story order before importing. Cutroom keeps references to local files only for the current tab, so moving or renaming them during an edit can interrupt playback.
Set the frame first
Choose the intended aspect ratio before adjusting crops and captions. A vertical social edit, square post and widescreen video need different safe areas, especially when platform controls cover the edges.
Mix speech and music
Keep voice intelligible by lowering music during speech. Use playback speed and tone controls conservatively, then listen through headphones and ordinary phone speakers before accepting the mix.
Review transitions
Hard cuts preserve timing and usually encode fastest. Fades and slides can clarify a change of scene, but too many transitions distract from the footage. Preview every boundary before the final render.
Browser export has practical limits
Long projects, high-resolution clips and many overlapping audio layers require more memory and processing time. Keep another copy of every source file, export a short test first, and leave the tab open until the download is complete. Cutroom does not claim full Premiere Pro compatibility or project interchange.
