Issues regarding to working with HEVC MP4 footage in Premiere Pro
“I am shooting 4K video with a Google Pixel 2 XL using Filmic Pro. In the interest of utilizing the best compression methods I utilized HEVC. Unfortunately, when I try to import these 4K HEVC MP4 files to Premiere Pro CC 2018, it only reads audio, there’s no image. How can I solve the issue?”
“I recently updated to Premiere Pro CC 2018 the most recent version. After the update, my Samsung NX1 HEVC MP4 files are no longer supported natively as it previously was. I can only hear the audio but cannot see the video. Is there an update coming that will support .mp4 video files that are HEVC? What should I do to go through this?”
If you are experiencing the same thing as mentioned above, we would recommend converting your 4K HEVC MP4 files to an edit friendly format first, such as DNxHD or ProRes. Here’s the workaround.
