problems with 24p footage

I shot some material for a short film a few months ago using a DVX100B camera and the 24P feature. I then edited the footage with Premier and burned it to a DVD with DVDit 6. Once on the DVD, the footage looked choppy, with horizontal lines showing up when the camera was panning. Does anyone know if this is a problem with the encoder used to burn it to a DVD, and if so, how to fix the problem? Thanks.
 
Sounds like you have interlaced video. There are few things that can add interlacing to your progressive video. In premiere you have to set up the project as a 24p project.

You probably did that and are thinking - thanks, but I did that. But wait, there's more.

After you capture the video from the dvx, you probably need to use the "interpret footage" function in premiere. In the project pane (list of files), right click on the video and select "Interpret footage." You will than have some options for frame rate and removing the pulldown. I can't recall the exact setup in this box since I'm not in front of Premiere, but change stuff and you will see the difference. I think you just need to check "remove 24p pulldown... Premiere will then see your video as 24p and not converted 60i. You should then see no interlacing....

Let me know if that worked.
 
It also depends on how you exported from Premiere and if DVDit is capable of making a 24p DVD.

If you exported the video as 29.97, you added interlacing back to it even if you removed the pulldown to begin with.

If you exported the video as 23.976, but DVDit isn't capable of making a 24p DVD, then it probably re-rendered the video to 29.97 and thus re-added interlacing.
 
I just put my 24p footage into a regular 29.97 timeline and the pulldown does the rest and the footage look badass.*I do export it as progressive footage. Encore does a fine job makin it into a dvd and it looks like "Head Trauma."


The only reason I found that out was that I would use the 24p timeline was for 24padvanced footage and if u wanted a film print.

This is also in premiere pro 1.0, 1.5 screw with my stuff and makes it for 24pa footage.
 
If you have 24p footage, you want to edit in 24p. If you edit in 29.97, all of your transitions, text, any motion you add, will be rendered at 29.97 and can badly mismatch your footage.

Premiere Pro 2.0 is like Vegas in that it makes editing in 24p a very easy choice, whether you shot in 24pA or standard 24p, so I don't understand why you wouldn't just edit in 24p every time you're editing 24p footage. Whether or not you're going to actual film, it's still 24p. You should match your timeline to the timebase of your footage.
 
I'm having the same problem in FCP.
I edited both 24p and 60i in 29.97 mode, it looks fine
Export via compressor M2V and Dolby for DVD Studio Pro
Burn a regular, non 24p DVD. The footage looks like ****.

How do I burn a DVD with both 60i and 24p without having the 24p be all jittery?
 
You should render it as a 23.976p MPEG-2 and make sure you don't re-render it as 29.97 anywhere along the way (in Compressor or DVDSP).
 
I'll try to phrase this question semi competently, but please forgive me if I screw it up. I am pretty new at this. I think I understand the difference between 24p and 24pa, sort of. And I know that Vegas 7 will do the pulldwn so that I can edit in 24p or 23.976p, so I'm not worried about that.

Here is my question (scenario): I want to shot 24pa to get the film look and also preserve optimal data. I am planning on rendering out for DVD, but I would also like the option of doing a film-out if the opportunity arises. I also want to intercut stock and historical footage into the timeline, some of which wasn't shot in 24p or pa. As I understand it, if I shoot in 24p, I can edit in a 29.97p timeline, which wouldn't affect the stock footage, but If I pull that non-24pa footage into the 23.976p timelime, I could get some noticeable motion artifacts. Is this true, and what is the best way to handle these scenarios?

I hope some of that made sense.
