after effect jittery video
I made an AE 6.5 animated video using combination of still photos from photoshop and JPGs. I have rendered it in AE and it looks great. I tried to edit the video and add audio on it in Premier Pro and after I render the final version on premier the video becomes jumpy every one or two seconds and I can see the interlacing lines when it jumps. I have tried several settings on Premier pro without any success. I re-edited the original AE footage on Final cut pro and I get the same thing. after I render the edited video on final cut it will become jumpy and I can see the interlacing lines. I have spent almost a month rendering using different settings on premier and final cut and get the same result. Can some one please help me I will be glad to send a portion the video for you to see what I mean. Thank you in advance.
he AE comp settings is as follows:
Preset= NTSC DV 720×480
pixel Aspect ratio= D1/DV NTSC (0.9)
Frame rate= 29.97Premier Pro settings:
Time base code = 30fps
NTSC = (Drop Frame) -

Have you checked field order?

Everything (settings) should match between Premiere’s timeline and AE’s comp.
codec: DV-NTSC
size: 720×480
field order (not “dominance”!) lower field first
frame rate: 29.97Do not scale the movie in AE’s Output Module if you’re rendering interlaced.
Does that help?

Hi steve
Thank you for your help. could you please tell me what you mean by not scaling the video down in out put module.here are the
AE render settings:
Quality =best
resolution = full
size = 720 x 480
frame blending = On
field render = off
pull down = off
motion blur = on
frame rate = 29.97
out put module = loseless
format = video for windows movie
out put info = no compression. -
Thanks for the specs.
1. An AVI with no compression will not play back on your computer without skipping. Low/no compression is for transfer between apps for further processing, not for playback. You should have rendered to a codec such as DV or Photo-JPEG if you expected to play it back in Premiere.
2. As for scaling, it looks as if you didn’t scale, so that’s okay. It’s in the output module settings under “stretch”. My warning was based on the fact that AE renders interlacing at the comp size and res first, then it scales down the interlacing. So you’d get a mush of lines of different sizes, which is irreparable, requiring access to original material.
3. I don’t think you saw interlacing, since you’ve rendered with field render off… unless you’ve used interlaced shot footage and did not separate fields for it. Interlacing is a series of 1-pixel high horizontal lines seen on fast motion. You might be seeing tearing on your monitor, which can’t keep up with the display.
What are you doing with your premiere movie? Going to tape? Going to web? Going to DVD?
