Some x264 codec encoding features

[LeoKac]

Please, answer these several questions: (NOTE, I am the guy who doesn't care about encoding speed, just need highest quality)

1) What is "DPB (Decoded Picture Buffer) size", and which value is the best to adjust? (The value is from 0 to 16)

2) Enable or disable Intra refresh? (This diasables IDR-frames)

3) Enable or disable Weighted B-frame references?

4) (This is from H.264 codec) Which value should I adjust on "Mark Every * I-frame as IDR" (The value is from 0 to 100'000)

5) Enable or disable "Fixed I-Frames Distance"?

6) Enable or disable "Adaptive B-Frame Placement?"

Thanks....

I don't understand why you keep posting these questions!?...

On the one hand, you state you don't know what these things mean and don't care to understand the whole reasoning behind what each item means. On the other hand, you state that you want the best possible quality, regardless of encode time. WHICH IS IT?

There is no magic wand, or BIG RED BUTTON, that automatically gives everything the best quality.

You either:
A) Have to understand about what the codec is doing to the video, and what various kinds of videos properties are, so that you can MANUALLY TWEAK the controls for best quality, or
B) Have to go with simple preset options that give above average quality (though NOT the best), to be used as general purpose encoding for those who don't have the time, or don't give a SHIT, or
C) Have to spend time trying each option, encoding a small segment and comparing them all to find out how each option affects the quality, so you end up with the best quality regardless of not knowing WHY it is that way

And until you are able to explain these and willing to provide info about type of content and type of intended display/audience, I'm not allowed to divulge my answers to these questions.
