Bit rate control
: ABR (Average BitRate, average bit rate), VBR (Variable BitRate, dynamic bit
rate), NearCBR (Near Constant BitRate, near constant bit rate), CBR (Costant BitRate, constant
bit rate)
Bit rate (Kbps)
: Video encoding bit rate.
Keep Resolution
: If the checkbox after "Keep Resolution" is checked
☑
, then the following
input box need not be filled, the system will keep the source resolution unchanged when
transcoding, otherwise you need to customize and fill in the desired resolution.
GOP
: It is mainly used in the case of HLS multi-rate output stream, generally set to off.
Scale
: When you need to stretch the source video from 4:3 to 16:9, you can choose to
automatically add black borders or intelligent stretching, the proportion of the source video has
been guaranteed.
Audio codec
: Supports aac, amr, ac3, mp2a and transparent, among which transparent is
transparent transmission, that is, no transcoding is performed on the input audio, and the default
format is commonly used.
Sampling rate
: The default is automatic, the system automatically obtains the audio sampling
rate of the source, and the supported sampling rate Rates 48000, 44100, 32000, 24000, 22050,
16000, 11025, 8000 etc.
