What SpeedPlayer is built for
- Reviewing your own videos and audio files
- Slowing playback down to a precision review mode (0.01x–0.24x, muted)
- Speeding playback up to 4.00x in continuous mode (audio preserved)
- Repeating a clip with A-B loops
- Resuming the same playback context later
Review access
- No login or account is required for the core workflow or App Review
- SpeedPlayer does not provide general web browsing or a public content feed
First checks
- Make sure the media format is supported
- Video: MP4, MOV, MKV, M4V, HLS streams
- Audio: MP3, AAC, M4A, FLAC, WAV, AIFF
- If a local file no longer exists, remove the record and import it again
- If a direct media link stops working, confirm the source still serves a playable asset
- SpeedPlayer relies on the system media framework for format compatibility — if a file doesn't play, it may not be in a compatible format
