You don't need to do this in two steps. > after analyzing both of videos with a tool named SpecialVH264, several > parameters differ between both videos, i.e: > constraint_set0_flag in the original video is 0, but in the one that im > generating the value is 1. You should also show us the difference of the console outputs of $ ffmpeg -i inputvideo $ ffmpeg -i outputvideo You should also show us the complete, uncut console output of your conversion. > is there a way that i can manipulate that constraint_set0_flag parameter? If I understand correctly, the flag says something about the profile. Indeed, libx264 has these code lines: https://github.com/mirror/x264/blob/d4099dd4c722f52c4f3c14575d7d39eb8fadb97f/encoder/set.c#L129 > sps->b_constraint_set0 = sps->i_profile_idc == PROFILE_BASELINE; > sps->b_constraint_set1 = sps->i_profile_idc <= PROFILE_MAIN; So it seems your video is created with the Baseline profile. (We would be able to see if you provided those outputs.) Basically, choose a higher profile, e.g. by adding the encoder option -profile:v Main or -profile:v High (It depends what you want constraint_set1_flag to be.)
