Hello everyone, I am trying to rip an old dvd(480p SD quality, VOB files) in mkv but I'm having a few questions regarding deinterlace, detelecine and other settings. I want to achieve high quality and small file size(~1300 avg kbps but using CRF for better quality) by using the slow or slower x264 preset, High Profile. My questions are the following(hope the mediainfo code below helps)(in descending order of importance if you dont have the time to answer them all):
1) is it better to leave video interlaced and the simply let vlc/mpc automatically deinterlace or should I encode with deinterlace?
2) Does the video need deinterlace and if so is decomb good at default settings? I want to achieve high quality and wouldn't mind using a slower but higher quality option. Should i use the EEDI2bob preset for decomb or something else or should i use yadif and if so which preset offers best quality?
3) does the video need detelecine?
4) when hoping for small file size should i use level 3 or 3.1 for small file size but high quality?
5) Is there any meaningful difference in quality when using slower instead of slow preset?(despite the lower encoding speed)
6) should i set it at constant or variable frame rate mode (same as source)?(will be using PC for playback so probably wont have compatibility issues)
7) Will the encode benefit(or worsen quality)by using a x264 tune(film)? It is an old 90s movie, real life footage with no CGI and moderate grain.
what audio mixdown should i choose in order to maintain original channels(at AAC 192 kbps)?
9) do general HQ and super HQ presets produce better results than MKV presets(modified to match preset and CRF value as general HQ preset)? Does the extra options: "ref=5:bframes=5" offer better quality in the super HQ preset?
Thanks for your help and I'm sorry for the inundation of questions.
