On the HAP website are instructions for transcoding media files using our free batch exporter, QuickTime, FFMPEG and other conversion utilities:
Here are some useful tips:
- Video codecs are typically a trade off between quality, file size and playback efficiency. The HAP codecs are optimized for low CPU usage during playback, at the expense of quality and file size, to handle extreme situations that traditional codecs can not handle.
- For the best playback results, make sure to use an SSD or other high speed drive.
- Use HAP Alpha and HAP Q Alpha for media files that contain alpha channels / transparency.
- When encoding media files in HAP Q / HAP Q Alpha, some software will offer an option to specify the number of chunks:
- For SD and HD sized media, use the default setting of 1.
- For ultra-hd content, eg 4k and larger, you can set this value up to the number of cores in the system that will be used for playback to further optimize playback performance. Usually a setting of 2 or 4 is appropriate.
