video from image source playback quality issues in packaging

I am attempting to package a video game for distribution. This game makes strong use of animations created by image sequences fed into image media sources fed into media players which are then played in widgets. When playing the game through the editor everything runs perfectly, but when I attempt to package the product suddenly the animations become choppy and stuttery. I’ve looked into scalability and everything is set to epic, all of my image media plugin settings should be right and nothing obvious jumps out that could be an issue in the packaging settings. Has anyone else encountered this? sorry if programing is the wrong place for this question.

update: No solution yet. For a time it seemed like ticking the “Full Rebuild” setting within packaging settings had an impact but if it did there is still a discrepancy between how the packaged project and pre packaging project run
