I have an image sequence to move composition which is creating inconsistent results. Generally the results are good but occasionally the last one or two images have longer frame durations which creates a stuttering effect on playback. The sequences are all 16 png images long so its easy to compare the results and spot the stuttering clips.

The video demonstrates the inconsistency, the first 16 frame loop stutters on the end frames, the second loop is smooth.

Is there a recommended workflow or strategy to feed images to Save Frames to Movie (vuo.video.save2) for consistent results?

Thanks in advance.
