Heads up before converting to MP4
What this specific conversion changes about your video.
Lossless when the codecs already fit
If your MOV uses codecs MP4 accepts, we remux (rewrap) it losslessly and instantly. A codec change re-encodes, which recompresses slightly.
Best practices for MP4
Small choices that keep your output sounding right.
- Play the MP4 result back before deleting your original MOV.
- Pick a preset (Web, Mobile, High quality) to balance size and quality for your MP4.
