Lagarith VS UTVideo

[Kawatta-kun]

I read that this new one, UTVideo, is better than Lagarith. In what way/ways?
Thanks.

[Zarxrax]

Its way faster.

Also, more stable with apps like premiere pro.

And about compression sizes? I'm doing one right now, and it seems to be smaller... I think lol .

And I still didn't got right, about the diferences between the four types of UTVideo.
I0ve read about RGB and YUV at the guide, and in another topic, but still, if I have to choose one or another, which one's the "best"?

Lagarith is smaller than UT, but not by much

You should generally always be compressing to yv12, which is the 420 option in utvideo.

If you are exporting from an editing application for import into another editing application, you should probably use the rgb option.

Just tried both at VDub, both gave me wrong. In the mediaplayerclassic it plays either bad (can't go further) or too fast.

I handle my stuff similar to how Zarxrax does. If I have to run a slow script on anything or otherwise need a large chunk of ripped footage for w/e reason, I'll compress to YV12 (420 option). I do it a little differently though in that, when I make clips for editing, I will always convert to RGB in AviSynth and make my clips in virtualdub, exporting with an RGB UTVideo format. This is because of the way Vegas handles video; as far as I'm aware, it will pass unprocessed YUV (no fades, no effects, just straight cuts) through, only changing colorspace on final export (and only if changing to an RGB colorspace on export), while converting anything in YUV that needs effects or any processing to RGB beforehand. It probably doesn't make any perceptible difference, but due to how conversions happen, it could introduce image problems if everything isn't converted the same way (one example would be color shades flickering between sequences with and without effects applied).

Aside from specific reasons for having a specific colorspace like the one I explained above, to maintain full quality you will want to keep your footage in the same colorspace as it already is. In AVSP, hit f5 to preview and it will show you the colorspace at the bottom. YV12 is 420, YUY2 is 422. I do not know how to find colorspace information in virtualdub.

Just another note: At least on my system, UTVideo doesn't work well with anything other than mod16 resolutions (as in, resolutions evenly divisible by 16, such as 720x480, 848x480, etc.)

Just tried many things about it x)
Every thing seems the same quality, tho yeah, diferent sizes.

You're telling me so that, choosing YUV420, is the best one, right?

And thanks!

In nearly every case as far as AMVs go, that is the correct option.
