There are three possible modes: - "abr": encode in average bitrate mode, specified in kilobits/sec (note, 1 kilobit is 1000 bits). You can make use of the vbv settings to control the bounds on how much the actual bitrate can fluctuate within the bounds of the average - "cqp": encode in constant quantizer mode. In general, crf will give better results, although cqp can be faster to encode - "crf": encode in constant rate factor mode. This will give a constant 'quality' to the encode, but with a variable bitrate |
