How to restore the timecodes in RAW h.264 and AAC without transcoding?

There is a program, which will affix the correct DTS/PTS (or whatever instead?) in RAW video format h.RAW 264 and AAC audio *without* conversion? Or, even better, would premaxilla TS -> MP4 (video format h.RAW 264 and AAC audio), putting the correct values for DTS/PTS.

Almost does not change the bitrate if you change the size of the video. How to fix?

Use for example this command to change the size of the video: ffmpeg -i 1.mp4 -c:v h264_nvenc -c:a libmp3lame -vf scale=-1:480 2.mp4 Codecs initially the same, but the bitrate and the size of the video is almost constant, although initially it is really good quality HD video. In what side to dig, prompt please.

So, if there is a preset Medium, then everything seems to be fine (though the quality leaves much to be desired), but if you put at least Slow, then...
