Lagarith RGB or YV12???

[sungod93]

I i was just wondering which do you think is the better format i should encode in? YV12 or RGB??


As i plan to edit the Lossless videos and then export it to a MPEG-2 file on a DVD.



Although i just need to know before i start ending what footage does my videos have to be in before i edit.

As there like 4 options in Lagarith RGB, YV12, etc

thanks

if you want a true lossless encoding use RGB unless your source is already YV12... or another colorspace.
In that case use the source colorspace (if supported by lagarith) to spare some diskspace without loosing quality.

YV12. RGB wastes space unless you'll be doing more color correction later on. All DVDs are in YV12, so more than that is a waste.

And in fact storing YV12 source as RGB forces a lossy color conversion as well.

Semi-related question: is there a quick way to determine what color space a Lagarith file was encoded with? The Adobe apps don't correctly show what mode is active, so I always worry I'm exporting to the wrong Lag mode from After Effects.

One quick useful way I can think of is open the AVI in VirtualDub, and render it, check the log and see which colour-space is being decoded.

Alternatively, a simple AviSynth script with:
AVISource("file.avi").Info()
should suffice also.

that's basically what i already said, uaing different words.

The OP needs to state the original colorspace of the material. Just because the final colorspace is going to be YV12, doesn't mean it should be used for the lossless file - that could ruin any hope of properly deinterlacing.

Edit: This was also implied by Sharktooth's original comment :)

i didnt thought at interlacing at all, however yes, reading again my answer, it implies that too.
