xtra's play jerky on standalone but powerdvd plays them nice

[MicroMij]

Hi, I'm backup up some dvd's of mine and I stumbled upon a problem today. It's a (pal) dvd of buffy with 3 episodes and a couple of extra's. I downsampled the episodes (bitrate 3300) and extra's (bitrate 3200) with DoItFast4U, ReAuthorist, DoCCE4U, Scenarist and ifoupdate.

All went well. I tested de final files with powerdvd and all works great. Menu, extra's look great and and the eps also...

One last test was to burn it on dvd and watch it on my tv. The episodes and menu all play well but when playing the extra's the image looks terrible and play verry jerky.

Anyone got an idee what's wrong here?

(xtra's are 4x3 and the eps are 16x9.)
(eps and extra's set to TopField first and Alternate scan in DoCCE4U (checked it with Bitrate Viewer and it should be right))

Sounds like you have field order problems, top field first when it should be bottom field first, or vice versa.

[MicroMij]

and to set it to bottom field first I only have to disable the tob field first in DoCCE4U?

read the cce faq. Especially Q10:

Top-Field First and Alternate Scan is needed when you deal with bottom field first interlaced which is very rare, so it's no wonder your video came out shaky. You can also read that in the CCE FAQ influenza mentioned.

Regarding BR Viewer there's IMO one important rule: never trust BR Viewer! :D (at least not on PAL sources, dunno how reliable it's on NTSC)

Maybe your setting didn't make the episodes shaky, 'cause they're progressive anyway.

Bitrate viewer reports almost all PAL main movies as being interlaced. I allways encode them as being progressive though ;)

Open your source in for example virtual dub to see if you're not sure.

And for the field order: you can translate Q10 to almost never check top field first!
And I always use deinterlacing on my PAL extras. I like the result (although some people do not like deinterlacing, but I think that applies to NTSC)

thanx all, I'll look into it!

[MicroMij]

it worked! thanx

I'm quitte new with these terms (tff/bff), but how do I set the extra's to deinterlacing in DoCCE4U? Is that the Alternate Scan option?

And how should I encode the episodes from now on? progressive or alternate scan?

[influenza]

The interlacing you set up in your AVS script. If you use dif4u you can check the checkbox and the script will be generated for you automatically.

What works for me for most movies is:

main movie progressive, top field not checked, scanning zigzag or alternate depends on bitrate viewer outcome
extra's (with deinterlacing lines in avs script!) same as main.

You encode it as being progressive since it's deinterlaced in the process (that's why encoding will be slower)

Well, it depends. TV Series are very often interlaced. I know that the first seasons of Buffy (german PAL) were interlaced, but the higher seasons with anamorph 16:9 picture are maybe progressive.

You could check with your eyes when opening a titleset in DVD2AVI and see if you find the so-called "interlaced combings" in the stream.

Have a look at a titleset in where you meanwhile know it's interlaced in dvd2avi. I think you'll know then what I mean with "interlaced combings".
