I just rendered it without the effects and just the affected part and found there to be no change.
Any idea on what could be causing this?
Do you understand and have a thorough knowledge of video formats and compression? If the problem is not a frame rate mis match then either an effect applied to the composition is the problem. Without details it's impossible to tell what is going on. Also, video can be 29.97 fps, or 30 fps. Do you know exactly what your footage and what your composition frame rate is?
The other problem could be your cache. You should purge the cache before rendering.
Hi, thanks for the reply.
I have enough knowledge on the subject I feel. I have rendered other videos with no problems. The source frame rate is 30 fps, but I tried to render in 30 and 29.97. The rest of the 3 minute video is using the same source footage, it is just a specific 15 second segment at the beginning. I tried rendering with the effects removed to no avail. If I render the initial footage in Premier with the same settings(H.264, 1080pHD) it is smooth, but if I transfer that segment from AE back to Premiere after adding effects, it isn't smooth anymore with the exact same render. It just seems to be that one area. I'm doubting it is the effects fault as the problem persists even when the effects are removed entirely.
Try flushing all caches in After Effects. Make sure both Premiere Pro and AE are up to date.
I tried clearing the cache and again, the problem was still there. I seemed to have managed to work around the problem though by completely starting over that segment of the clip. I imported the raw footage into After Effects and cut it down to be perfectly in line with the old one. My test render of just that part seemed to come out good, effects and all, so now I'm rendering the full thing with high hopes. The rest of the clips are untouched imported straight from Premiere still. Perhaps that clip got corrupted somehow?
Thanks for your input nonetheless.
