A simple question - no knowledge of codecs, etc. necessary. I've labelled the two versions as "A" and "B", with the order determined by a coin flip, to remove bias. It's just a still scenery shot so don't expect to see the hot chicks or scary monsters.

Which do you prefer? All opinions welcome, and please say why.

AVI file of "A" vs "B" Blu-ray sources (35.1MB, 1020x630 YV12 encoded with Lagarith lossless video codec)

This is a direct crop from the same section of each 1920x1080 video. Play it at 100% (DO NOT ZOOM OR FULL-SCREEN) and you'll get an exact reproduction of a part of the video played on your display.

Video creation method:
- DirectShowSource into AviSynth using ffdshow
- Crop(200,300,-700,-150) used on both videos
- Subtitle filter used to overlay "A"/"B" text
- no colorspace conversion
- synched to same start frame, 50 frames saved
- losslessly compressed using Lagarith with YV12 setting
- AVIs appended into one file using VirtualDub's Direct Stream Copy

EDIT: Or not... I hit the post button too soon. There's no way to delete your own threads? Mod? I guess it's a poll without the poll.

I downloaded but unfortunately Windows media player won't play it back and encountered a problem.....I guess i don't have the codec to play it installed on my system.

Still with fast broadband it only took 90 seconds to download so no harm done.

See the link to the right of the video to download the codec required.

Does it really matter? The MPEG2 version I have looks great.

Still shots in the other thread suggest that the original AVC encode provides a noticeably superior image, so the blind comp is worthwhile.

So what's your opinion of the video?

B looks better to me but you have to take into account i'm using a 19inch 1280x1024 monitor to view it.....Hope i picked the AVC encode....The A pic had very distracting problems on this monitor anyways and was looking poorer because of it.

I have to say though that i recall mentioning that particular shot on another thread as looking poor ( when i thought there was only one version that existed - now i reckon the poor shot is MPEG2 and the other is the AVC which i have picked out as looking good )

Would be interesting to see another shot perhaps in the darkness of the underground caves.

Since it's a "manual" poll now I can add the second video to this same thread instead of starting a new one.

Flicking around later in the movie I decided upon this nice green-bathed shot. Or did you want one with less light?

Coin flipped again so the order may or may not have switched - different symbols as a result.

Clip A is quite clearly DNR'ed to heck. Clip B looks miles better and must be the AVC. I'm watching on a Hitachi old-schhol CRT PC monitor. The differences are rather obvious.

I'll check that out tomorrow....Going to bed now...I was hoping you could put some clips in the caves with a lot of darkness as generally dark shot scenes will have more grain just because of the way 35mm and camera's work thus i also imagine more smoothing would be on the MPEG2 clip if you could find one to do for the thread....I'd like to see just how bad/good the MPEG2 edition looks in the dark cave scenes.

Yeah, I think I can pick these out very clearly. There's enough grain, especially in the second shot where I'd understand people finding it distracting and wanting it removed (even if I could never agree with them, I'd understand)... but the DNR that's been done just provides dancing clumps that are more distracting than the even veil of grain that's present in the other encode.. Shots B and 2 are the non-DNR'ed AVC encode and shots A and 1 are the DNR'ed MPEG-2 encode.

Edit: I will say that at 100% video size on my 22" 1680x1050 monitor, the DNR is not as bad as what's present on some titles. It's obvious that it's been used but the faces in that second shot haven't yet taken on that hated wax museum appearance. Of course, I might have an entirely different opinion watching it on my 92" FP setup.

Without a shadow of a doubt i prefer clip 2....clip 1 looks much worse and background details are worse.

Grain is more consistent in clip 2 and is clumpy and messed up in clip 1....Not even close to my eyes and it's clip 2 all the way.

I added the poll (you can edit the thread and add a poll). You should be able to modify the selection text if you want. If not, tell me what it should read and I should be able to change it.
