What lossless codec do you prefer?

[System25]

I want to make a little poll. With only 5 questions:
1.- What do you prefer in lossless video compression ¿compression speed or compression ratio?
2.- Which colourspace do you use more (RGB, YUY2, YUV12) ?
3.- What kind of video do you code with lossless codecs (anime, real video movies, flash to avi, 3d animation)?
4.- What is your favourite (most used) lossless codec?
5.- Why do you prefer this codec?

Thank you for participate!

I think these kinds of threads are all over the place, but I'll go along with it.

1. I consider speed and compression about equal importance.
2. YV12 mostly, RGB sometimes.
3. I often compress anime or custom-made graphics.
4. I use Lagarith for everything.
5. I primarily use it for being able to edit the video later. Since all frames are keyframes, it is very suited to this purpose. For archiving footage, it is simply "good enough" that I don't bother using anything else.

1.- I require speed more - as it must be fast enough for Full PAL or NTSC capture without framedrops on my system, but compression ratio is quite important

2.- YUY2

3.- AVI to DVD (usually MPEG2)

4.- I end up going back to HuffYuv or the ArithYuv derirative, but I am very interested in trying new lossless codecs, Lagarith is looking very promising and I might well end up switching to it when I upgrade to a P4 3.2ghz prescott (from my P3)

5.- HuffYuv / ArithYuv is most suited for using on my system for my captures at this time.

if you plan to do a dvd as final purpouse then you don't need yuy2, yv12 is enought as mpeg2 dvd standard is yv12....

for my analog to dvd caoture i use vble a beta codec codded by marcfd there's no setting, the encoding is fast (when i had a PIII 900 i caputed 720*576 vble+pcm without a frame drop), the decoding is slower than the encoding but it's loseless, compress much more than huff and is realy easy to use....

Heck, this comes up when I capture most! :D

1) Speed and compression are both important, speed for the capturing, compression for the archiving.

2) YUY2 and YV12, YUY2 for the capture and filtering, YV12 for DVD authoring.

3) VHS stuff

4) I use 3, HuffYUV, Lagarith and FFV1

5) HuffYUV and Lagarith for the speed, FFV1 cause it compresses good.

Me... I would like to use MPEG-4 AVC lossless ;)

I think although I am not sure, but my BT878a chip of my capture card is supposed to support YUY2 as how it works - can't remember where I read that, Then I convert to YV12 when encoding to MPEG2 for the DVD. Should I be better capturing in YV12 (or attempting to) with my board? I want to aim for best quality by the 'preserving' methods (least loss ways during sll the steps, no filtering etc)

Whether you capture directly into YV12 or convert to YV12 right after you capture shouldn't matter, either one should result in the same output.

If the material you are capturing is interlaced don't use YV12, use YUY2.
