> I don't know what you want to achieve... i want to make a high-quality screen recoding using MPEG2 video codec. so i can use it for editing stuff through an editing program of choice. to that end i had to ensure the GOP number (-g command) is set to 1 while also attempting to raise the quality of the recorded video, hence why i had to use -bitrate parameter. > Are you sure that you want to use pcm_s16be? > It might reduce compatibility of your output file. i mean, i *could* use something like AC-3, MP2 or even MP3 but when i use those codecs i get some intense hissing from them *not* during recording but from the recorded file *after* recording. compatibility is not something i usually think of when recording MPEG stuff. in fact the only way i could get to check if my file is compatible with other programs and devices and whatnot is through ffprobe, i could try to check if my recording is compatible with VirtualDub2 as that is all i have right now but i tend to focus on recording stuff first and then worry about compatibility stuff later. > Use -q 2 instead of -q 1, -bitrate has no effect afaict. i'll keep that in mind. > It is not possible to synchronize these two streams as they have very > different start-times. damn... the closest thing i've ever managed to do such a thing was to apply an "adelay" filter and do some guesswork with it. turns out even that isn't feasible. > I don't know if "use_wallclock_as_timestamps 1" helps in your case. OK, i'll be trying out this command that you have suggested. i'll report back when i'm done.
