Container format | MP4、FLV、HLS、MOV、TS、WEBM、MKV |
Configuration items | Video and/or audio parameters |
Video codec | H.264, H.265, H.266, VP8, VP9, AV1 |
Video bitrate | 0 or [128, 35000]. 0 means to use the original video bitrate. |
Video resolution (px) | 0 or [128, 4096] for either dimension. 0 means to use the original resolution. |
Frame rate (fps) | [0, 120]. 0 means to use the original frame rate. |
Audio codec | AAC, MP3, Opus |
Sampling rate (Hz) | 32000, 44100, or 48000 |
Audio bitrate (Kbps) | 0 or 26-256. 0 means to use the original audio bitrate. |
Sound channels | Mono or dual |
Templates created are displayed in the template list. You can view, edit, or delete custom templates, but preset templates can be viewed only, not edited or deleted.
