Frame order - jerky motion on TV

[mharney]

I asked this elsewhere and thought I might try here as well.

I am new to video encoding and have had the jerky motion problem with my DVD's and my TV set.

Here is what I do:

VCR Tapes input through Hauppauge WinTV PCI card (composite) using VirtualDUB

Use TMPGEnc 2.57 Pro to encode to MPG (I do use source ranges to edit beginning and end)

DVDit! LE (came with my DVD-RAM/R drive) to author


What happens:

I author a disk with a simple menu with buttons referencing two roughly 30 min long videos.

It appears so far that the first video on the disk is flickery. The second is not.

I am not sure it it is just coincidence that this happens (guess I could swap the videos and see if they correlate, thus wasting ANOTHER DISK) or what, but I have some questions.

1.) I assume that VirtualDUB is making sure that the field order is A first (top) when it captures the video, and I guess the way I understand it, every other frame is top field. If I use TMPGenc to decode to MPG, and I choose a source range, will TMPGEnc make sure that the field order does not swap, no matter what frame number I choose, or is it a matter of me having to adjust for odd or even numbered frames specified as start frames? Am I ignorant or is this a reasonable line of thought?

2.) Should I TRUST TMPGEnc to judge field order or should I assume that the process prior to it is always right about the field order?

3.) What role if any, does DVDit! LE take in arranging frames during disk build?

4.) What can I do to determine the field order of an MPG video I have completed, to make sure before I write the DVD? I've wasted more disks than I care to discuss, just getting to this point of understanding.

Thanks to anyone that can help me.

I figured it out. I had some settings wrong in TMPGEnc.

[CryptKeeper]

which settings were wrong?

Source video should have been interlaced. Field Order should be (in my case) A. Just have to make sure that TMPGEnc is set right for source and target types.
