Then I rendered out a new 1920x1080 reference video.Īfter that test, it was obvious that After Effects did not automatically conform the 30fps JPEG sequence to 29.97 when dropped into a 29.97 composition. Then, I dropped in my JPEG sequence and audio as before. So, instead of creating an After Effects composition with the same specs as the JPEG sequence, I manually created a new composition and set the frame rate to 29.97fps. Upon further study, it was noted that the JPEG sequence was a full 30fps, which didn't match the 29.97fps project. So, the problem was with the JPEG sequence. The results were good: the audio was in sync. When I noticed the audio issue, I went back to my Master composition and spot-checked all audio, to make sure the audio of individual elements within the comp lined up with the final audio mix.Ĭonfident that all video was in sync with the audio inside of my Master composition, I rendered out a short 10-second sample from the Master composition. I rendered my ProRes file from the JPEG sequence, rather than from the Master composition, because it wouldn't take near as long. I rendered that out as a 1920x1080 ProRes file for review. I dropped in the audio from the Master composition. I re-imported my JPEG sequence and created a new composition based on those specs. I took my Master composition and rendered it out as a JPEG sequence. I'll spare you the details of every troubleshooting step I took in this process and skip right ahead to the solution that was discovered.Īll of the audio sync issues were due to the JPEG sequence itself. The only realy problem? The audio slowly drifted out of sync with the video. Afterwards, I was able to get a better sense of flow, pacing, and transitions. So, to see the video, I had to render it out as a 1920x1080 ProRes 422 file. A RAM preview would take forever (The JPEG sequence took roughly 20 hours to export). Now, with a project that large, I couldn't preview the video in real-time within After Effects. So, I delivered the entire video as a JPEG sequence with the audio as a separate WAV file. A ProRes file at that frame size was too large, but an MPEG4 at half the frame size was too compressed, and the final video looked pixelated when scaled. I just wasn't able to render something that large with a codec that could bring the file size down to a real-time, playable video. The reason? An A/V company we were working with for a live event planned on handling all of the compression for us, since the composition was a whopping 15,000 pixels by 3,000 pixels. After completing a recent project in After Effects, I rendered out the entire 8 minute video as a JPEG sequence.
