[FFmpeg-user] need help with making an "in sync" screen recording.

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.

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.

i'll keep that in mind.

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.

OK, i'll be trying out this command that you have suggested. i'll report back when i'm done.
