EOS R5 Mark II video codec not supported

JuGreaves — Tue, 08 Oct 2024 18:45:12 GMT

Hi to all in the community. I sure hope someone can help!

I have an R5 ii. I have captured video clips in CLOG2.

I can't get anything to play them and they wont work in the free version of DaVinci Resolve.

Everything just says something like "codec not supported".

I'm new to video. Can someone please explain to me in non-technical language what I need to do?

Many thanks,

Julian

The free version of Resolve is limited in various ways, so that you would have a reason to buy the Studio version. One limitation is that it doesn't support advanced codecs, like the 10-bit video your camera is probably recording.

Various things you could try:

set your camera to record 8-bit
transcode your video to 8-bit, for example using Handbrake
buy Resolve Stiudio

Which you do is up to you. For people doing advanced video, buying a full video editor (like Resolve Studio or Premiere Pro) would be considered pretty basic. If you're not doing serious video, then 8-bit should be fine.

Many thanks. I'll give the 8 bit resolution a try. 🙂

I don't think it's a great idea to shoot CLOG 2 at 8 bits on a R5 ii.

Also you should keep in mind that the "bit number" is not the resolution of the video, but the color depth.
8 bits video won't look great after color grading, which is actually a fundamental step when working with clog footage.

To give you a tase of the issue, 8-bit videos can represent up to 16 million colors, while 10-bit videos can reproduce 1,073,741,824 colors, which is 64 times of the colors of the 8-bit. It's a HUGE difference.

Normally, you either shoot videos in a standard color profile (not log) at 8 bits, or you shoot log at 10 bits or higher.

Clog 2 is also the "hardest" log profile to grade, so definitely not a good idea for starting out.

If you have a R5 ii in your hands, you might want to use it right and with the right software.

Hi Atticus,

I've tried all of the above, including splashing out for the paid version of DVR Studio.

I'm still getting the same message "codec not recognised". I'mrecording in Clog2.

Any other ideas?

Thnx, Julian

Thanks for the advice.

I've splashed out on DVR Studio but I'm still getting the same message 😞

Sorry, no idea! I don't have an R5, so I can't check this myself (my cameras have Canon's video OS), but it seems to me that it should certainly work.

Are you sure you're using DVR Studio (not the free version)? In the title bar it should say "DaVinci Resolver Studio!, and likewise in the "About" box. Sounds like a dumb suggestion, I know, but I've upgraded software in the past and found myself still running the old version.

Greetings ,

Can you please provide all of the details about the shooting modes you are capturing in.

How are you transferring your clips to the computer?

DaVinci should be able to support most anything. The free version supports 4k up to 3860 x 2140 60p

Studio support 4K 4096 x 2160 > 32k.

Hi Rick,

Many thanks for your reply.

I'm shooting clog2 XF-HVEC S YCC422 and simply copying to my pc from the CF Xpress reader.

Regards, Julian

Thnx,

Yep. Just checked. Definitely DVR Studio!

XF-HEVC is a pretty new thing; it's possible that Resolve doesn't support it yet...? Having said that, their list of supported codecs does list XF-HEVC, as of August 2024.

https://documents.blackmagicdesign.com/SupportNotes/DaVinci_Resolve_19_Supported_Codec_List.pdf?_v=1723705210000

And XF-HEVC S? I don't know what that is. Maybe that's an issue.

Unfortunately I don't have a camera that can record XF-HEVC. For the record, though, XF-AVC 4:2:2 10-bit does work in Resolve.
