avisynth histogram , histogram("color")
ffmpeg/ffplay -vf histogram, either colors, waveform, levels modes
mm thanks, but how is the commandline to generate a video file with "overimpressed" vector/waveform?
ffplay -i "barsSD.MXF" -vf "split[a][b];[a]format=gray,histogram=mode=waveform:waveform_mode=column,vflip,split[c][d];[b]pad=iw:ih+256[padded];[c]geq=g=1:b=1[red];[d]geq=r=1:b=1,crop=in_w:220:0:16[mid];[red][mid]overlay=0:16[wave];[padded][wave]overlay=0:H-h"
mmm I think is beautiful with ffmpeg, only I cannot see the "scale" in volt, for example my analog waveform indicate the 1Vp/p on the blank bar, whit this commandline seems similar but have not the scale that indicate level in millivolt, is there a way to see it? thanks
