Hi, I need help. I have HVEC video files that will not play in Quick Time and, therefore also are causing me issues in Avid Media Composer. I have converted to MOV in multiple converters but then the file plays with no video. I am on Windows 11. Anyone know how to get these files working in QT? I feel like that will solve it in Avid. Thank you.
Codec Long Name H.265 / HEVC (High Efficiency Video Coding)
Profile Main 10
You can check the movie codec details with MediaInfo (Mac and Windows) or Invisor (Mac).
YMMV because you are using Windows. AFAIK Windows needs HEVC add-ons to support it. Or convert HEVC H.265 to H.264.
On the Mac HEVC plays OK in macOS 10.13 High Sierra or later but there is a little catch:
macOS 15 Sequoia QuickTime Player does not play HEVC H.265 if it happens to have Codec ID hev1 instead hvc1 (ffmpeg defaults to hev1).
macOS 10.14 Mojave QuickTime Player does not play H.265 with Chroma subsampling 4:2:2 (Bit depth 10 bits).
ffmpeg can losslessly and very fast fix that H.265 with Codec ID hev1:
You can run ffmpeg via Shutter Encoder GUI. Browse... or drag and drop the input movie to select it. In the "Choose function" field instead of selecting anything, paste the code below, then [-> to the right of that] select .mp4, and if needed Change the Output folder [by default it is Same as source]. Then click "Start function". (About the same output via Rewrap as .mp4).
ffmpeg -c copy -tag:v hvc1

Or the same ffmpeg command via the Terminal:
ffmpeg -i input.mp4 -c copy -tag:v hvc1 output.mp4
