I'm currently encoding my dvd collection for convenience.
Before encoding this particular title of DVD, I've made some samples and when playing them at TV I noticed that upscaled (with ffmpeg) videos looks better than the original VOB (upscaled by TV).
I assume it's because the media player of the TV applies less efficient scaling compared to ffmpeg's scale filter.
I don't know if it will be always the case, so I decided to keep the original scale for now.
Maybe in the future I'll end up scaling the encoded (x264, mp4) video, am I losing quality doing this? Should I apply the scale filter while encoding the VOB to MP4 or scaling the MP4 will give the same quality?
While watching the samples I didn't saw any diference but maybe I missing something since comparing videos is very difficult.
