I have problems with my Premiere Pro. It is first time this has happened, and I cannot understand why.
I am creating a timelapse from my images. When I want to export media, I choose format H.264 (not H.264 Blu-ray), dimensions 1920x1080. Output name is visible as "Sequence02.mp4".
After export is finished, there is a file "Sequence02.m4v" on disk. Why? What causes Premiere to change file format by itself? I used Premiere before and this never happened. Maybe I'm using some different setting, but what could cause this change?
m4v
is just an alternate name formp4
(it can sometimes indicate the presence of drm, but that shouldn't be a problem here), so you should be able to simply rename the file.
