Frequently Asked Questions
Does the audio stay in sync?
Yes. The audio track is time-stretched to match the new video speed.
What speeds are supported?
0.5×, 0.75×, 1.25×, 1.5× and 2× on this site.
What is the maximum file size?
500MB is a refusal limit, not a guaranteed processing limit. Files over 500MB are refused. A file at or below 500MB is not guaranteed to process successfully. Reliable processing limits vary by tool, file, and device, and have only been verified for the cases in the test record (for example, trimmer segment processing at 492 MB and full audio transcode at 99 MB). A full-video re-encode at 500 MB has not been tested.
Does my file get uploaded anywhere?
This build is designed so processing runs in your browser, without sending your file to a server. In testing, tool runs made no requests outside this site. When you first use a tool, your browser loads the processing engine from this site itself; your file itself is not sent anywhere.
