AVS720 is a known P2P/internal release group focusing on high-quality 720p encodes with sensible bitrates. Their AVS720 tag refers to the encoder/source team, not codec specs.
The x264 encoder is the workhorse of high-quality video compression. It is an open-source library that, when tuned properly, delivers transparent visual quality (meaning indistinguishable from the source) at half the bitrate of older codecs like XviD or MPEG-2.

| Issue | Fix |
|-------|-----|
| Subtitles not showing | In VLC: Subtitle > Add Subtitle File (if external) or enable Track if internal PGS |
| Audio sync off | Remux with mkvmerge delay option: --sync 0:-200ms |
| Color banding | Slight chance due to 720p compression. Use MPV with --deband filter |
| Letterboxing not exact | Normal for 2.35:1 within 16:9 container. Nothing wrong. | mkvmerge -o output
