What changes when you convert MP4 to OGG
- Both formats are lossy. Re-encoding adds a second generation of loss, so keep quality high (80+) unless size matters more than fidelity.
- MP4 video animation cannot be expressed in OGG audio; the first frame is converted as a still image.
- The video’s audio track is extracted and re-encoded to OGG audio; video frames are discarded.
- OGG audio encoding exposes a quality control; around 80 is the usual sweet spot.
