When I try to import an MP4 file into Premiere Pro 15.0, the progress bar freezes and will not load the files. They are MP4 files from After Effects that are 7 seconds long. I have tried many different problem solving techniques but nothing seems to fix the issue and I am at a loss of what to do.
Please use the image insert button, otherwise we have to download your images to view them. We don't like doing that. 😠
Are they files you have exported from After Effects yourself? Firstly I would try another format rather than MP4 which is likely 'lossy'. Try ProRes or DNX.
I exported from After Effects to Media Encoder to save as an MP4.
Maybe try Mike's suggestion as a test. What happened? Let us know.
I'm having the same issue as well.
