Wrong render settings?
I am having troubles with the end result from a render in AE. I have a person on a blue screen and keyed it out to a nice animated background. The background is 24fps and my blue screen footage is 29.97. I used a plugin from videocopilot to change the fps to match 29.97. I have set the field settings to lower and render out to Quicktime animation. I also changed the PAR to conform to DV widescreen (16:9 (1.2)) because all my footage is 1920×1080. After the project renders it plays fine for about a second until my person on the blue screen starts talking and moving his arms. The video seems to stop and then plays very slow. He is stationary and was off-center so I adjusted his body. Is there a small setting I am missing? Very new at this and gaining grey hair by the render. Any help would be appreciated!

This might just be because you are using the QT animation codec which is an intermediate lossless codec: I assume your final vid is many GBs in size? This is a good format for archiving or if you’re going to do further processing on your footage, but not for final delivery or even watching on your computer. It’s just too big. Try rendering out a compressed QT – e.g. h.264 – and see if the problem persists.
By the way, you may not need to go through all the rigmarole of using Andrew’s preset, depending on the nature of the naimated bg. You could just interpret the footage to play at the correct frame rate for your comp. If it’s going to fast / slow, enable time remapping and drag the keyframe at the end until you’ve got the speed you want.

Thanks for the response. The footage I am working on will be imported into Premiere but will be delivered on DVD for cable access TV as well as regular dvds. I thought about just burning it anyway to see if the DVD player would handle it. The files are indeed several GB’s in size for a 30 seconds. I will try a small size to see if it works, thanks.

Yeah, your dvd software will compress the animation to mpeg for the dvd and, assuming your footage has no other problems, it will play fine. However, if you’re delivering via a playable dvd (as opposed to a data dvd) you’re going to want to downgrade the dimensions of the movie. DVD only supports standard definition (720 x 576(PAL)/480(NTSC).

Thanks for the advice. I tried a different render, I used mpeg2 at 720×480 and it plays perfect. I cannot import this into Premiere and load it onto a timeline with 1920×1080 footage though can I?
Should I just convert my hd footage to 720×480? The footage will always be delivered in an SD format I guess. Seems like a lot of work to get footage to match. Hopefully the quicktime animation will just work on dvd.

You should be able to import it, but you’ll have to scale it up to fit to the width of the screen. It’s a shame to have to downgrade your other footage, but if you’re only going to output to SD it’s not too much of a loss.
By the way, in case you don’t know, you can match the scale etc of a number of clips in prem by setting one how you like it, copying it, then selecting the other clips, right clicking, and choosing paste attributes (I think that’s what it’s called).
The quicktime animation from AE works fine on DVD in my experience.

I’ll try to strectch the footage and see how it plays on DVD. Why do you suppose I can’t play the HD comp without smoothness? I have a quadcore/4gb memory/ geforce 9800. HDD too slow? I thought about purchasing a raptor drive but not sure if it would help. I guess I don’t realize how demanding multiple HD streams are. Thanks for the help though. I can at least get my project finished now.

I just think animations aren’t supposed to be watchable. But if it’s your final render before compression, there’s no need to watch it!
Remember though that DVD won’t support high def footage. You’ll have to downgrade to 720 x 480 (or x 576 for PAL) if you’re planning on Encore (or whatever software you’re using to make DVDs) allowing you to import it.
