I have a sub-3-minute sequence in Premiere CC, containing a single 4k DCI 23.98 AVC stream from a Sony FS7, with a couple static PNGs and 29.97 Quicktime Animation lower thirds.
I need to export to a quicktime wrapper around some sort of mpeg-4 codec; I've tried several configurations of H.264 and MPEG-4 with the same result.
My timeline plays and looks normal, but after export, I see the following result via Imgur videotogif:
Because I know some of you will ask, here is a screenshot of my export settings:
Changing resolution, codec (within variants of Quicktime), with/without previews, max render quality - all has no effect on the strobing issue.
Anyone have any thoughts on what the problem might be here?
I'm having the same issue with a visually similar sequence in the same project for the same client, and had it once before as well (you guessed it, same client, same content specs). I've never experienced this ever before so I'm inclined to think there's some little gremlin in there somewhere - but I'm dashed to figure out what it is.
I've also verified that the issue occurs when exporting to P2/MXF as well as ProRes.
Per @Mulvya's question about source properties, here's a screencap of the properties window on one of the clips. All the footage was shot in the same session, same camera, etc, and should be completely identical:
