I use PE13 on a Win10 box with the HEVC codec installed. Of course, any HEVC video will come into PE13 as audio only (can be converted in Handbrake). I bought PE21 but I need to make blurays so I reverted to PE13. I have used a gopro 8 with the video compression set to H.264 + HEVC successfully in PE13. The gopro 8 will output H.264 on 1080 30, 1080 60, 2.7K 60, 4K 30 and 4K 60. I just bought a gopro 10 and set the compression to H.264 + HEVC and found that this gopro version will still only output HEVC only when set to 1080 24 and 1080 30 and 4K 60 but will output H.264 when set to 1080 60 and 4K 30. There is no warning that this will happen even when the video compression setting is H.264 + HEVC. I contacted gopro to inform them of this deficiency but I won't be holding my breath for their fix.
You certainly won't see a "fix" for version 13. But since version 2020, you can edit HEVC video at 30 fps in Premiere Elements.
Yes, but I need to burn blurays so I can't use my PE 21. It would be nice if Adobe continued support for bluray burning in PE then I wouldn't need to be so concerned about gopro's inconsistent output (and their fix). Not looking for a fix for PE 13.
Since you have version 13 for burning Blu-Rays and it works for you. There is a solution.
Create your project in your version 21 and output a complete, high quality MP4/H.264 intermediate video. Open version 13 using the newly created output as the only media. Then, burn the Blu-Ray. If you need menus, you should be able to create them in the second project inside version 13.
That's good to know if I ever mistakenly record in HEVC.
