C-log (Canon) footage from EOS R5 crashes Vegas Pro 18

Christopher-Frost wrote on 8/17/2020, 4:41 AM

Just bought a new Canon EOS R5. 8k and 4k normal video (IPB and ALL-I) works fine in Vegas Pro 18. But 8k RAW and any kind of C-log footage (8k or 4k) crashes Vegas (MP4 file). I can play back the footage in VLC player (albeit at a surprisingly slow frame rate). But when I import the media file into Vegas, and it sits in the media bin (although with a corrupted-looking thumbnail) and when I click on it or try to move it into the timeline, Vegas freezes and crashes without and error message. I haven't adjusted anything in the internal options in Vegas, and no plug-ins installed except the effects ones that come with Vegas, so I'm working in 'vanilla' mode here. Working on a powerful new computer here, specs below. Any help appreciated!

 

AMD Ryzen 7 3800X

Asus Prime B450-PLUS (DDR4, USB 3.1, 6Gb/s)

32GB Corsair VENGEANCE DDR4 3200MHz (2x16GB)

4GB NVIDIA GEFORCE GTX 1650 SUPER - HDMI (latest drivers updated)

Vegas installed onto 500GB Samsung 970 EVO M.2 drive, media stored on 2TB Seagate Ironwold 7200 RPM 128MB CACHE

Windows 10 Home 64-Bit

RAW video isn't yet supported in VEGAS, but it is high on the priority list. ProRes RAW support is awaiting Apple's green light, and I'm sure other formats will follow soon. No idea why CLog isn't working., though even if it does, there is no view transform built into the ACES setup for that, that's something they need to update.

Can you upload a sample clip if this incompatible media (The CLog, not RAW, we already know it won't work) and post a link to it here?

That's HEVC 4.2.2 (5.1) Vegas is not compatible. It's quite ridiculous in my opinion that they didn't see the 4.2.2 HEVC wave hit, and didn't have VP18 ready for all the cameras's using it. The other editors may not be able to practically edit this format either due to lack of GPU decode for 4.2.2, but they don't crash and corrupt the video, and with enough CPU, could still make it work, although you just need compatibility then create the proxy.

Thanks so much for your help - I'll give Premiere Pro a try. Thanks again

Or maybe (just a guess) they did, but got hit with another wave called COVID-19, which set some features that were meant for launch back to be included with future updates instead. Some of that format support was held up by third parties not responding in time for release, as well. That said, expanding format support is one of the key goals for VEGAS currently.

Could you possibly give me some ideas for transcoding the footage? I'm having trouble finding suggestions online. What I want to do is to try transcoding that HEVC 4.2.2 so that I can work with it in Vegas. I'm happy to transcode it to a much bigger format (plenty of hard drive space)...but I want to keep hold of the extra colour depth and dynamic range of the 10-bit c-log footage for colour grading. I've heard that transcoding to MPEG2 is a possibility. I use Any Video Converter at the moment.

VP18 canot read your video file. I import your video file into Davinci resolve studio 16 edit and play back nicely.

Use Happy Otter Scripts to convert it to Magic YUV.

I was going to suggest sony catalyst as sony have a hevc 4:2:2 10bit codec. I just tried it, and it can't read the sony variant, so that's no good. Then I thought davinci resolve would be ok to make the transcode with but apparently the free version can't read 10bit files. I know ffmpeg can do it via command line, but ideally there would be a simple free gui app. Handbrake doesn't have the ability either. Are you in an R5 users group, this must come up all the time, although with other NLE's they can turn on proxies/optimised media from within their editor

TMPGEnc Video Mastering Works 7, they have a free trial version you can download and see if it helps your particular issue. Here's the product homepage for you to look it over: Pegasys Software Video Mastering Works 7 

Hope it helps.

I'm in the same boat. Did you find a proxy workflow that allows you to keep CLog?

Christopher-Frost wrote on 10/26/2020, 3:07 AM

My wife has Adobe suite (I cant be bothered to learn Premiere, though), so I used Adobe's video processing program to process the C-Log footage into Prores 422, and that seems to work well.

j.razz wrote on 10/26/2020, 1:47 PM

Thanks Christopher. I too have Adobe Premiere. I'll give their processing program a look as I don't use it, but I do use AE.

I've been transcoding my R5 footage to standard H.264 with HandBrake (free software). Not only are the files then smaller (depending on quality you choose), but Vegas can actually open them without crashing or choking on unsupported codecs/standards. This works for 4K120 and Log footage for sure. I have not tried transcoding Raw or 8k yet. After using Vegas since version 1.0 I almost switched over to Davinci Resolve due to these issues but HandBrake has kept me with Vegas for now. I really don't want to leave but come on, Magix!

@Christopher-Frost You can rewrap it into a mov to keep your 10-bit video and pcm audio with VirtualDub2 which can function as a gui for ffmpeg without any scripts. Vegas supports that fine but gpu's dont... so better if you also transcode the chroma subsampling to 4:2:0 in the process. If you shoot c-log you'll still need to use the appropriate Canon lut.

No need for vdub for such a case.

Download ffmpeg. Put the ffmpeg.exe into the same folder where your video is. Press and hold 'Shift' and click with the right mouse button into empty space in the folder. Select Command Prompt (if you still have it) or PowerShell. There you can easy use this command 'ffmpeg.exe -i SOURCEVIDEO.XXX -c copy OUTPUT.MOV'
If it is a .mov container compatible codec it will work like a charm. If not try .MP4 instead in the output.
