Properties

bitrate

Desired bitrate of the output stream, in bits per second. If only a number is specified then it defines the average_bitrate. The max_bitrate is then set to 1.25x this value.

• Type: number | { average_bitrate: number; max_bitrate: number; }
• Default value: Constant quality mode with crf value based on resolution. Visit FFmpeg docs to learn more.

Properties

average_bitrate

Average bitrate measured in bits per second. Encoder will try to keep the bitrate around the provided average, but may temporarily increase it to the provided max bitrate.

• Type: number

max_bitrate

• Type: number

---

keyframe_interval_ms

---

pixel_format
