Free · Editable preview
How it works
- 01
Choose a short MP4, WebM or compatible MOV.
- 02
Select an output ratio, framing mode and crop position.
- 03
Preview playback, then export MP4 or WebM with supported audio retained.
Why it helps
Make a bounded video variant with the framing you actually previewed.
For example: A creator reframes a landscape clip for a portrait story while keeping its original audio.
Good to know
Uses your browser’s media codecs. Unsupported tracks produce an error; audio is not silently discarded. Clips are limited to 60 seconds, 100 MB and 4K input. Select the clip again after reload.
Continue with the relevant website, design, content or customer workflow in Automyc. See the platform.
Questions
Is the clip uploaded?
No. Video resizing and export happen locally in your browser.
Why might an export format be unavailable?
Encoding and decoding depend on your browser and the source codecs. Try the other output format or a standard H.264/AAC MP4.
Where is my work saved?
When browser storage is available, editable drafts stay on this device for up to seven days. Clearing site data removes them. Video clips must be selected again after reload; temporary processing results have separate limits shown in the tool. Download important work.
Does this start an Automyc trial?
No. Using a free tool, or creating a free account from one, does not create a workspace or start a paid trial.
