| Frame-type options: | |
| • --keyint <integer> (x264) | |
| • -g <integer> (FFmpeg) | |
| • Keyframe interval, also known as GOP length. This determines the maximum distance between I-frames. Very high GOP lengths will result in slightly more efficient compression, but will make seeking in the video somewhat more difficult. Recommended default: 250 | |
| • --min-keyint <integer> (x264) | |
| • -keyint_min <integer> (FFmpeg) | |
| • Minimum GOP length, the minimum distance between I-frames. Recommended default: 25 | |
| • --scenecut <integer> (x264) |
