MPEG4 quality saved in MATLAB

Question

I need to get an mpeg4 file to use in another application, from an original mpeg4 video I loaded into matlab and edited (frame by frame). To do so, I tried using VideoWriter, se

Answer 1

MPEG-4is a compressed format so there is information loss when you save it in this format. Quality is the quality of the compression but you do not want any compression. To force Matlab not to use compression my guess is to use the statement below as the default is H.264

    newVid.VideoCompressionMethod = 'none'
