CCE encoded progressive video playback issues

[tedkunich]

Hi all,

I just finished burning a LD capture and the playback on my Pioneer DVL-919 looks like crap. There are heavy interlacing artifacts on pans in the video. I almost looks like the field order is reversed, but should not be the case as the video source is pure progresive.

The source material is 16:9 anamorphic, 23.967 fps encoded with CCE (2.67) @ CBR of 8100, authored with Maestro. I applied pulldown to the .mpv and everything looks fine on the PC, but screwy on the SA player. Also, when looking at the top and bottom boarders it looks like the field pairs are offset by a large amount - after the very first line of video, it looks like the next one is black, as if the next frame has been shifted down a line or two. I can see this as I single step frame by frame, the picture shifts up and down a line or two. Oh yea, this is NTSC land.

Has anyone seen of anything like this before? I know I have played "progressive" DVD's in this player before without problems, but I'm at a loss to explain what is going on as the PC plays back the DVD fine, the VOB's when opened in VirtualDub look fine....

Any thoughts would be greatly appreciated.

A little update, the same source encoded with the trial TMPGEnc does not exhibit this jumping phenomena. I selected the pulldown within TMPGEng and it plays back perfectly on a progressive scan player. The CCE encoded w/Pulldown jumps with the 3:2 pattern. I would go the TMPEG route, but I am unaware of a way to set Iframes at specific frames like CCE can. I really do not want to manually place 80 odd chapters by hand. ;)

Make sure the "Offset Line" setting is set to zero on CCE's video settings.

Thanks RB, but it is already set to zero. If it would help, here is my .ecl file:

Does anything look out of place? my avisynth script simply trims and adds a short message at the end to "change discs".

I can definitly see the frame jump up and down a line in the 3:2 pattern on the DVD playback - very visible at the the top and bottom borders of the leterboxing. If it matters, the source has been sized to anamorphic (720x360) with a 60 pixel top and bottom border added. Playback of the avi and the mpeg on the computer (in VirtualDub Mod) do not show this jumping.

OK, I feel like an idiot... found that the jumping line thing was really an artifact of my player. Setting it to display 16:9 output vs. letterboxed solved the problem - my TV will take a 16:9 input and appropriatly scale it.

Still does not explain why the tmpgenc versions did not exhibit this phenomena, but at this point, the issue is moot.
