Which Codec UT Video Codec RGB vs RGBA / YUV420 vs YUV422

[Toshi.des]

So I have installed the UT Video Codec from the AMVapp but I have no clue which one to use when exporting from PPRO or VDUB.

When Exporting in PPRO I have these options:
Ut Video Codec RGB (ULRG) VCM x64
Ut Video Codec RGBA (ULRA) VCM x64
Ut Video Codec YUV420 (ULY0) VCM x64
Ut Video Codec YUV422 (ULY2) VCM x64

in VDub I have the same but the end in x86 so I am guessing VDub will not take advantage of 64 bit systems?

Anyway if someone could provide some info on which one is best for what or point me in the direction where I could find more info I would greatly appreciated it!

To the 1st question, YUV420.

To the 2nd: It will if you have a 64bit version of Vdub.

Great thanks!

Anything I should know about the others or YUV420 is the best choice for everything?

For anime you'll generally want to use YUV420 for reasons that explaining is a bit of a tl;dr you most likely won't care about. However you might need/want to use RGBA depending on the situation (for example, exporting effects from after effects or something and overlaying them on your footage in your timeline in your main NLE), but unless needed for such specific situation it's not something you should generally go for.

For any none anime related projects is YUV420 still the best choice?

No, you use what your source material is. Every DVD you find will be I420 so using YUV420 makes sense, regardless of actual content. If your source is I422 though, you use YUY422, or if it's RGB, you use RGB. You just use what your source is (unless you have a reason to change it.)

What Mister Hatt said is right, however consider that DVDs and Blu-rays and, hell, even Transport Streams you'd record from TV or any raw you'd find around is yv12... hence why I said for anime you'll generally want to use YUV420.

[Mister Hatt]

I was addressing his question of content other than anime though.

How do you find which codec your source is using, DG index doesn't seem to display that information when I preview it.

Mediainfo. Check what says for format under video.
