Canon HEVC playback video issues M4/M5?

[macman4789]

Hi,

I’ve recently been delving into some video work and specifically Clog3 shot on a Canon R50 V. I have chosen to shoot in XF-HEVC S YCC 422 10-bit.

The issue I’m having seems to be whenever I try to get the files off the SD card, MacOS just doesn’t like it at all. It either hangs and just doesn’t even show up when I connect the card reader or I insert directly into the Mac studio. Eventually, it does show up and it shows the files which are .mp4 but they are white generic icons with ‘.mp4’ on them. When I try and open them and choose quixktime, after a long time of waiting the first frame shows but it’s like not even the full file and you cannot scrub or anything. If I then try and drag them onto my desktop, it just comes up with a generic error saying could not complete operation. I’ve tried this both on an M4 Max Studio and an M5 Pro MBP which should both have absolutely no issues with reading HEVC files I thought?

The weird thing is, when I plug the same SD card reader and SD card into my much less powerful i5 10th gen Windows laptop, the computer can read and launch playback of the files straight away off the card and has no issue copying them off the card. It just plays the flat profile video in Windows Media Player.

So my question really is am I missing something? I would have thought the most recent Mac OS with Apple Silicon wouldn’t break a sweat reading this? Or are there known issues with this sort of Canon footage?

Thanks for any ideas

On first thought it sounds like the SD card is dying. Have you tried a different SD card on your new Mac? You might also consider reformatting the SD card.

After copying them off with the Windows machine, can you copy the file to your mac and see if it plays? If it doesn't, there's probably something up with the video files themselves.

Or, if you are using an SD to USB adapter, the adapter could be dying. That is what happened to me a while back. It seemed to be some kind of Heisenbug, and then, I suddenly noticed the object I was holding in my hand.

Hi, yeah the thing is it’s a brand new card. I thought at first it would have been the card but the fact it seems to work perfectly fine on the windows machine makes me think it’s a macOS thing seen as it’s the same on two different macs. I put the card in straight away and formatted it in camera straight away.

Yeah, when I transfer them to a Mac they play fine. It’s just the messing around of having to put them from a windows laptop to an external drive and then to a Mac.

Thanks for the input

Yeah I was using a usb c UHS II reader but that seemed to work on my windows laptop. Also, to rule out the reader, I took the sd card and put it directly into the Mac studio’s sd reader and got the same outcome. Thanks for the suggestions!

There's your answer.
The solution is "in there".

It’s not a solution though is it. Not being able to play HEVC files on an M4 Max or M5 Pro isn’t a solution. It’s a problem, hence my post… to try and solve the problem….

Having to use Windows laptop to get them off the SD card, then copy them to a drive then copy them over to a Mac is a ‘workaround’ but one that I shouldn’t have to do….

Thank you to those who have tried to contribute to the problem I have constructively so far.
