Frequently Asked Questions
Are all videos supported?
No. Even if the extension is the same, this browser may not be able to read it depending on the internal codec. If an error occurs, check the source code created with a supported codec or another browser.
Is it always smaller than the original?
No. It may be larger if the original is already heavily compressed or has high settings. GIFs are also often larger than short videos, so compare the resulting files.
