Output file is a mess - judder & interlaced....

[The.King]

Hi,

OK, so I have a wedding video (source file was a .vob) which I extracted/ripped with dvd decrypter and then edited with Adobe Premier Elements 7 to change a lot of footage, add soundtracks, etc.

A few weeks later, I have the finished product, but no matter how I encode and save the output file (I've tried PAL DVD to keep it the same as the source, I've also tried NTSC DVD, MPeg2, .avi, 720px25fps & 1080ix25fps, and a few others) the resulting file is dire.

I end up with either what looks like a interlaced/combed (jagged edge) type-picture or, I have no jagged edges at all - everything is fine, but as soon as the camera moves/pans - everything in view is very jumpy (like the frames are on top of each other in the wrong sequence or something?)

I can run the interlaced/combed - type file through Staxrip and re-encode with H.264 and change the container to MP4 and everything is fine - which is great for me as I have a TivX media player which will play anything. But for giving a copy of the video to people to play on stand alone DVD players, I need a .vob or iso file image to burn to a blank disc.

I'm sure avisynth has a written code to figure this out, but I can't get my head around that program at all.

Do anyone know of a program to use to obtain a judder-free, de-interlaced .vob file that I can burn to a disc? Pleeeaaaassseeeee.

Thanks in advance.

Make sure PE is correctly detecting that your source is interlaced and which field order it is.

If, during movement, like the panning shots you described, it kind of goes 2-steps-forward-1-step-back, playing very jerky, then most likely you inadvertently switched the field order somewhere along the way. There's a chance you can fix it without starting all over by taking the video (M2V) and opening it in ReStream to change the field order. If it's already only in DVD format, you'll have to demux first. It can work only with the elementary streams (the video alone). Then remux/reauthor it.

And you can't resize interlaced video (to 720p and 1080i, like you mentioned) unless you know what you're doing, or make it progressive first by deinterlacing it.

Hi and thanks for replying...

"jagabo: Make sure PE is correctly detecting that your source is interlaced and which field order it is."

It is.

"manono: If, during movement, like the panning shots you described, it kind of goes 2-steps-forward-1-step-back, playing very jerky, then most likely you inadvertently switched the field order somewhere along the way."

I haven't. I've just triple checked it and the field order is correct - lower first. I've even tried it the other way around - it makes things worse.

"And you can't resize interlaced video (to 720p and 1080i, like you mentioned) unless you know what you're doing, or make it progressive first by deinterlacing it."

I know. This is one of my points. If I make it progressive and change the container when encoding it, everything is fine - the initial point was I can't get the original outputted MPeg2 or .vob file progressive without encoding it again - and with the field order correct, the image is all judder-like?

I can't help you with Premier Elements settings but I can tell you that DVD players and televisions fully support interlaced video. So if you get your video encoded properly, interlaced with the correct field order, no vertical resizing (unless you use an interlace aware resizer), you shouldn't have any problems.

How about a short sample from one of your encodes that shows the problem?

Run the source .vob file in GSpot and post a screenshot.
