Re: how to improve video quality of .mp4 file
In general you cannot really 'improve' the quality of a file that has more than likely already been transcoded from an original source. Your best options are to either:
- Find the original source and make a direct copy of it, retaining its original specifications.
- Transcode the original source to the codecs and specifications of your choice. This will downsample the original quality but with skill this will not really be noticeable.
You think that's air you're breathing now?
