DV avi export issues at DVinfo.net

Clint Comer · August 22nd, 2005, 01:47 AM

Hey guys, do search on this and didn't really come up with what I was looking for. I am using 24p, 16x9 footage shot with my XL-2 in Premiere Pro 1.5. My issue is after I render out a my avi and play it the image bounces. All the settings are correct, 720x480, 16x9, 24.976 frame rate. Is there something I am missing? Does something need to be checked, unchecked?

Clint,
Not sure what you mean by "the image bounces." Can you either describe in more detail what's happening, or post a short clip, and also some more information on your rendered AVI settings? (Also, presume that you typo'd and meant "23.976" rather than "24.976" for the frame rate?)

Clint Comer · August 22nd, 2005, 10:34 PM

Yes 23.976 and by bounces I mean that it litterly bounces up and down. or the bottom and top keep moving up and down. As for settings I don't really mess with the setting too much. just make sure that its the right frame rate, aspect ratio, that sort of thing.

It sounds like a field order problem but I am not sure how it should be set for 23.976.

Anybody else ?

Hmmm, not much info to go on. Two guesses:

1. Windows Media Player does not handle 24pA exported AVI's properly. See the clips at my web site (http://www.geosynchrony.com/scratchpad.htm) and scroll down to the section titled 24p Advanced Anomaly in Adobe Premiere Pro 1.5.

2. Perhaps the wrong 24p project or export settings (24p vs 24pA)?

your footage looks similar to mine but I didn't shoot in 24pA mode. Still haven't solved this one. I wish I had more time to play with it. But I have about 3 other problems at the same time.

I had to deinterlace the footage for some reason. But once I did everything was fine.

Clint,

Oh, you didn't deinterlace in Premiere, did you? The quality of Premiere's deinterlace is quite possibly the worst of any method available. You should be seeing a rather obvious drop in quality. You should never have to deinterlace 24p footage. Some other project property or export setting must have been set wrong. Just because it fixed the problem, doesn't mean it's the way to go.

I agree with that, but it was the only thing that seemed to solve it. I ran 10 test renders and it was the only one that didn't bounce like that.

You could try changing the 24p Pull-Up method. To do this, go to Project>Project Settings, under General click Playback Settings, and then under 24p Pull-Up Method choose whichever is the opposite of the one currently selected. In mine the default is "Interlaced Frame (2:3:3:2), and the other choice is "Repeat Frame (ABBCD).

I noticed the same effect when exporting 24P footage from Premiere. I don't have a 24P-enabled camcorder, but I composite 24fps animations elements in After Effects, and output as 24P DV-AVI to edit in Premiere.

I had this similar problem but when I imported the footage as an asset in Encore it simply went away.
