Dave Matthews Band interlace lines

[framerman]

I have done many movies, but this one stumps me. NTSC Dave Matthews Band Listener Supported on dvd comes out real jerky with some interlace lines. I used CCE to encode. I have checked with bitrate viewer as to what encoding settings I need, and I have rechecked again. I have the settings right. I have also set my max bitrate lower. This is my first concert movie. I don't know if there are different settings on these or not. I'm wondering if I need to check progressive instead of interlaced in CCE or not. Has anyone done concerts and succeeded, or even better the DMB concert? Can anyone give me a direction to go in?

Edit:

One thing I noticed that is deffinitely different is when I encode the concert, CCE goes much slower. I'm used to 1.35 to 1.45 consistently. Concert is at best 1.05. I'm thinking I need to change the settings in CCE.

Maybe your source is telecined. Or worse: plain interlaced. In such case, no matter how you setup the encoder, you will not succeed if you don't apply some preprocessing.

To check which case you are facing, take a look at this excellent tutorial:

Hope this helps.

I've done this DVD and many, many other concert DVDs. Most concert DVDs are interlaced 29.97 fps source. Assuming your outputing to a DVD then you do not need to deinterlace, CCE & MPEG2 handles interlaced material just fine. If your going to a VCD that is a different matter that I have no experience with. Important things to remember.

1. In DVD2AVI, DO NOT check the force film mode (you want to leave it at 29.97 fps).

2. In CCE, do not check the progressive box (your source is interlaced). Also, do not check the top field first box (search forum for many discussions about this).

3. DO NOT use avisynth (or anything else) to do a IVTC, it's not needed.

4. Burn a small sample to a DVD+/-RW disk to check out the result on a TV, if it looks jerky then the field order must be reversed. This problem will not reveal itself on a computer monitor. You can use the pulldown utility to switch the field order (but make sure you don't add the pulldown flag).
Ex: pulldown src.mp2 dst.mp2 -nopulldown -tff even


That's it, it will be perfect.

The only one that I haven't tried yet is your #3. I'm a little rusty at different encoding methods because I've gotten in a good groove. I use avisynth exclusively, but you say not to. I am putting this on a DVD and I use CCE to encode. Could you please tell me what method I use to encode on CCE without the .avs script. Do I drop an mpeg file directly to CCE? Thanks.

Edit:

I think I misread your statement wrong. I thought what you said was not to use AviSynth. I assume you mean not to do an IVTC in AviSynth, but still use AviSynth. What I'm trying now is to reverse the field order in DVD2AVI. I'm not forcing FILM, so it will stay at 29.97fps. I have Progressive unchecked in CCE, and also top field first unchecked.

You were correct, I was saying that you do not need to use Avisynth (for anything).

If you prefer (and your using an older version of CCE that will accept .avs files) then you can use Avisynth with mpeg2dec.dll and CCE should run a little faster. This is only a preference (for a faster encode time) and not a requirement.

The alternative is that when you use DVD2AVI you create a .d2v file. Then use the VFAPI converter to create a .avi file from the .d2v. Use CCE (any version) to load the resulting .avi file and encode as interlaced.

I think there are some tutorials that describe this.
