Hello, I am using the twixtor plugin in after effects. The RAM preview that displays is smooth, however, when I render the video, and i have tried several times with different settings, the playback is choppy. It appears that the media player cannot continuously play the video because the time cursor actually stops when the video does, causing the choppy playback. The video is about a minute long, but it rendered to be 10.2GB somehow. Is the large size the problem? Should I let After Effects guess how to interperate the footage? I have read on one somewhat related forum that it is a graphics card issue. Any help would be appreciated.
