Premiere won’t read HEVC with AIFF audio

This entry was posted in H.265/HEVC Converter HEVC/H.265 in Premiere on by

So you just failed to import HEVC H.265 files with AIFF audio into Premiere for further editing? Couldn’t figure out a way to solve the issue? Actually, HEVC files have to be encoded with AAC audio to be usable in Premiere. If your files were HEVC with AIFF audio, Premiere will refuse to open them. In that case you need to convert the HEVC AIFF files to an edit-friendly format first before bringing them into Adobe Premiere.

Can’t import AIFF HEVC-videos to Premiere Pro (2018)
“Hi guys, I have issues working with HEVC-videos in Premiere Pro (2018). I understand the HEVC format only works on the paid version of the Adobe Premiere, meaning you have to do the signature with the Adobe so that the suite imports the HEVC format natively. Unfortunately, my Premiere Pro CC 2018 (12.0.1), the paid version, still won’t open my HEVC files for unknown reasons. What a frustrating thing! Does anyone have any ideas on this? I would really appreciate any help. Thanks!”

Currently, Premiere Pro supports HEVC + AAC audio, and HEVC + AIFF audio is not readable. To be able to make HEVC + AIFF usable in Premiere, you need to convert it to a compatible format first, such as DNxHD or Apple ProRes. Here’s a guide telling you how to do this step by step.
