Frequently Asked Questions
CRF (Constant Rate Factor) controls video quality. Lower values mean higher quality but larger files. Values between 23-28 are recommended for most uses.
Depending on the CRF setting, you can achieve 30-80% file size reduction.
No, compression reduces file size by adjusting quality parameters, not resolution.
If compression fails: (1) use a file under 500MB, (2) try a lower quality setting (higher CRF = faster processing), (3) convert to MP4 first, (4) refresh the page and retry.
