FAQ
Will compression affect quality?
Lower resolution/bitrate or lossy compression (low CRF) reduces quality. Increase bitrate or choose higher quality profiles to balance size and clarity.
How to choose CRF vs bitrate?
Lower CRF → higher quality/larger size; common range 18–28. Constant bitrate fits fixed-size needs; CRF allocates bitrate adaptively to preserve quality.
What if the file is too large to upload?
Reduce resolution or bitrate before upload, process in segments, or choose a more efficient codec like H.265 to shrink size.
