About DAT to MP4 (H.265)
Convert DAT to MP4 (H.265). DAT is the Video-CD sector dump wrapping MPEG-1 streams. MP4 (H.265) stores HEVC video, cutting bitrate roughly in half versus H.264. HEVC decoding needs newer hardware and encodes more slowly..
Why convert DAT to MP4 (H.265)?
- Smaller files with MP4 (H.265) lossy compression.
- Keep animation and transparency where supported.
- Private, no upload - runs in your browser.

| Typical use | DAT is the Video-CD sector dump wrapping MPEG-1 streams. | MP4 (H.265) stores HEVC video, cutting bitrate roughly in half versus H.264. |
When not to convert DAT to MP4 (H.265)
- Skip MP4 (H.265) for archival masters: lossy compression discards detail, so keep the DAT original.
- Keep a master copy: repeated exports stack small losses, so archive DAT before batch MP4 (H.265) shares.
Limits
Starting point: DAT - DAT is the Video-CD sector dump wrapping MPEG-1 streams. Rip sector headers first; raw sector dumps may fail to open. HEVC decoding needs newer hardware and encodes more slowly. Encode MP4 (H.265) (H.265 / AAC) from DAT at a bitrate near the source, and confirm the audio track before converting.
How conversion works
Conversion runs entirely in your browser with FFmpeg WASM. Files never leave your device.
