First, thanks for the reply. Regarding your points:
1: I skipped the TIF export from Camera Raw and just opened the NEF files as a seqence in AE. So far it works...but why do you think the writer of that video tutorial had us do this? What would be the point? After the video is rendered, it wouldn't matter if the photos were TIF, JPG or NEF right? A rendered video is a rendered video...or am I wrong about this?
2: I started using Media Encorder to do the rendering. Seemed pretty straight forward however my initial problem hasn't been fixed. The video is still choppy. I did a bunch of research on timelapse since my original post and have isolated some possibilities related to exposure time and interval of the photos when shot. However I'm not yet convinced that this is the issue. I've also read up a bunch on bitrates for video codecs and containers. Have a pretty firm grasp of the concepts and have selected values for all that should work.
3: The AE composition is virtually barebones, simply adding the photos into 1080p 24fps. No editing.
Anyways, Im rendering a video right now. If its choppy, I'll put up a youtube link and hopefully can get some more input.
K yeah, here it is....how do I improve this?
