What to expect
- Re-encoding is mandatory: AVI does not support H.264 or HEVC, so the video must be decoded and re-encoded to Xvid or MPEG-4, which always causes some quality loss.
- Output files are usually larger than the source because Xvid is less efficient than H.264 at the same visual quality level.
- Audio is re-encoded too: AAC from
MOVis converted to MP3 insideAVI, adding a second quality step.
Frequently asked questions
Does converting MOV to AVI lose quality?
Yes - there is no lossless path from MOV to AVI for H.264 or HEVC video. Using a high quality setting such as
-q:v 3 in FFmpeg keeps the loss minimal for typical footage.Why is the AVI file larger than my original MOV?
Xvid is less efficient than H.264 at the same perceived quality, so a larger output is expected. Lowering the quality setting is the only way to reduce size.
Does this work with iPhone MOV files?
Yes. Both H.264 and HEVC iPhone footage can be converted, though HEVC sources from iPhone 7 and later take longer to process.
Is there a 4 GB size limit for AVI files?
The original AVI spec caps files at 4 GB; modern encoders use the OpenDML extension to go beyond this, but some older players may reject files over that limit.
