EOS R5 Mark II RAW Video Glitches with Vintage/Non-Electronic Lenses

Greg_S — Wed, 04 Sep 2024 23:51:34 GMT

Hi everyone, I just got an R5 Mark II and am having issues with RAW video shot with vintage manual lenses. I have several old lenses in my collection that don’t communicate electronically with the camera. I’ve tested them alongside newer lenses, and every other file type works beautifully— no problem with RAW stills and MP4 video. RAW video files work fine with new lenses, but the only RAW playback that works when shot with a non-electronic lens is on the camera itself. Once I transfer the files, they’re loaded with glitches in Cinema RAW Development and they’re actually crashing both DaVinci Resolve and Premiere Pro. There are dropped frames, changes in brightness/color, glitch frames, and occasionally frames that almost look like academy leader. It's pretty messed up. Attaching images.

Has anyone else experienced this? Is there a camera setting or decoder plug-in I’m missing?

Greetings,,

It sounds like you have a decent setup. Are you certain your system meets the minimum requirements for RAW video playback? I believe you indicated that raw files recorded with newer lenses plays normally on a computer, correct? Are you using the latest version of Cinema Raw Development?

How are you transferring the captured video from the card?

Are you using a Canon brand EF to EOS R adapter?

Hi there, great questions, thank you for responding.

I have a Mac Studio with an M1 Ultra card. I’m a commercial video editor and regularly work with 6K/8K files from ARRI, Red, Sony, etc. The Canon RAW files shot on the newer electronic lenses play back flawlessly in all my apps.

I installed all the latest Canon software just a few days ago. I’m connecting the camera directly to the Mac and transferring via EOS Utility 3.

I do have the Canon EF to EOS R adaptor, but the old lenses are M42 mount so I also have a Fotodiox adaptor disc in the mix as well.

Hey Greg!

oh my god this is bad! it's happening to me as well and today we shot a whole fashion project on vintage glass and canon adapters, have you figure it out?

this is a big big problem now

Greetings ,

Since both of you are able to reproduce this behavior consistently, I think it would be a good idea to contact Canon support.

Really sorry to hear you're having the same problem too... no solution yet as far as I know. Definitely contact support.

Thanks Rick. Been waiting to hear back from support for days.

The same error happens for me. With manual lens, RAW video glitches (concentric black rings, green glitch, crash) and crashes windows and resolve. But it plays back fine on camera. With an RF lens, raw video plays back fine on windows or resolve.

Thank you for posting. Have you reached out to Canon Support? I'm still waiting to hear back and am going to contact them again and reiterate that it's not a localized problem. I'll post with any updates.

Haven't yet

I think the footage itself is OK, ie not corrupted, but obviously uneditable at the moment.

I’m still waiting for Canon to answer, in the meanwhile I had to go and rent an Atomos and record all the clips one by one to salvage the footage, since the client obviously couldn’t wait for the problem to be solved

Wow— that thought had crossed my mind but just seemed like such a crazy workaround... glad you were able to salvage the shoot!

Quick question— did you transfer the raw files by connecting the camera via EOS Utility, or did you use a CF card reader? I have a dialog going with support and I can only attest to the direct connection, as I don’t have a reader for CF Express.

I transferred everything with the CF reader as this is what I do for all my sessions. Even right now I’m shooting RAW videos with RF lenses and all is good

Same problem. Music video all shot on vintage lenses, playback is fine on the atomos. Shot a whole music video with it. Transfered everything with a card reader. Neither Davinci resolve or Premiere pro can read those files. I am getting pretty nervous. I'm glad you're in a dialog with Canon because here in Canada there is no way to be able to have someone helping you out.

Thank you for posting. Support has passed the issue along to their engineers to replicate and identify the issue. They said it may take up to five days to get a response. I'll post when I hear back.

By the way I think I was also able to open a support ticket without opening a repair demand here in Canada (so I was probably incorrect by saying we can't get help here in Canada). I might actualy have help, and will come back here with developpement if there are any.

Huge update : if I try to read the file FROM the card through the cf express card reader, my computer can ready the footage fine.

Oh wait... it was working until I imported more files in Davinci. This is getting weird.
