Hello! Second time posting but with new information. I have a two minute experimental microfilm and I lose important material when exporting to Vimeo. I've played around with all of the different formats and extending the lost clip times and taking general advice I have found in these forums, but I am still not finding the answer. Basically, the clips are a collection from a ipad, an iphone, and my dell computer's internal video recorder, and is a combo of mp4 and mov files. It looks like the Dell video clips are the ones not getting transferred. The Dell clips are in mp4 and are unsuccessfully transferring; the ipad/iphone clips are in mov and seem to transfer correctly. What is odd is I am also using audio from the mp4 clips, and those are converting successfully. It is just the visuals that are getting lost.
I tried saving the film and putting it through Handbrake, but Handbrake rejected it too. Has anyone experienced anything like this and what are your ideas? I tried pulling the clips through Handbrake pre-compilation but it did not work then either, and I elected to just go with the files I already had saved. Advice appreciated!!
