Bitrate Encode
This flow element will ALWAYS encode a video to the quality level and codec specific.
Codec
The codec used to encode the video.
| Name | Notes |
|---|---|
| H.264 | Older codec, wide playback support, but larger files |
| HEVC (Automatic) | Often called H.265, newer codec, about 30% the size of H.264 with same quality. Automatic will using 8-bit or 10-bit depending on the source video |
| HEVC (8-Bit) | Forces 8-bit HEVC video, this has wider support than 10-bit |
| HEVC (10-Bit) | 10-bit color depth produces more colors and better quality, but has less hardware support. Sometimes called main10 |
| AV-1 | New codec, smaller than HEVC, but not many devices support this codec yet |
| AV-1 (10-Bit) | 10-bit color depth produces more colors and better quality |
| VP9 | Googles codec, similar to HEVC, with better browser playback support, but only QSV can hardware encode this codec |
Encoder
The encoder to use.
You can specific a specific encoder or let the system test to see which hardware encoder is available.
But specific a specific hardware encoder, this will by pass any changes and force it to use this encoder.
If you specify a hardware encoder that is unavailable, the encode will fail.
Automatic
When automatic is set, FileFlows will test to see if hardware encoders are available on the Node and if so will use hardware encoding, otherwise will fallback to CPU encoding.
Hardware encoder order:
- Video Toolbox (Mac Only)
- NVIDIA
- QSV (Intel)
- AMD (AMF)
- VAAPI
- CPU (fallback)
Bitrate
The bitrate in Kbps to encode the video in.
Depending on the video encoder, this bitrate will be used, or if the source video's bitrate is less than the desired, then the source bitrate will be used.
For example, NVIDIA will not use a higher bitrate but CPU and QSV will.
