Psnr : Error variables will be set during encoding. Obmc : Use overlapped block motion compensation ( H.263+ ). Mv4 : Use four motion vector by macroblock ( MPEG-4 ). croptop : Set top crop band size ( in pixels ).Īic : H.263 advanced intra coding / MPEG-4 ac prediction.Īlt : Enable alternate scantable ( MPEG-2/MPEG-4 ).īitexact : Use only bitexact stuff ( except (i)dct ).Ĭbp : Use rate distortion optimization for cbp. cropright : Set right crop band size ( in pixels ). cropleft : Set left crop band size ( in pixels ). cropbottom : Set bottom crop band size ( in pixels ). Vlc ( 0 ) : Variable length coder / huffman coder. W97 ( 12 ) : 9/7 wavelet ( only used in Snow ). W53 ( 11 ) : 5/3 wavelet ( only used in Snow ). Nsse ( 10 ) : Noise preserving sum of squared differences. Vsse ( 9 ) : Sum of squared vertical differences. Vsad ( 8 ) : Sum of absolute vertical differences. Rd ( 6 ) : Rate distortion optimal, slow. Psnr ( 4 ) : Sum of squared quantization errors ( avoid, low quality ).īit ( 5 ) : Number of bits needed for the block. Satd ( 2 ) : Sum of absolute Hadamard transformed differences.ĭct ( 3 ) : Sum of absolute DCT transformed differences. Sad ( 0 ) : Sum of absolute differences, fast ( default ).

cmp : Full pel motion estimation compare function. bufsize : Set rate control buffer size ( in bits ). b_strategy : Strategy to choose between I/P/B-frames ( 0 = off / 1 = on ). bf : Set number of B-frames ( supported for MPEG-1, MPEG-2 and MPEG-4 ). b : Set video bitrate in bit/s ( default = 200k ).

async 1 is a special case where only the start of the audio stream is corrected without any later correction. The parameter is the maximum samples per second by which the audio is changed. Audio will be stretched or squeezed to match the timestamps. ar : Set audio sampling frequency in Hz ( default = 44100 Hz ). Pcm_s16le : Uncompressed 16-bit PCM Audio

ab : Set audio bitrate in bit/s ( default = 64k ). Each occurrence is then applied to the next input or output file. Therefore, order is important and you can have the same option on the command line multiple times. Note : As a general rule, options are applied to the next specified file.
