Here it is!

I'll test the footage on my computer listed in my signature below.

@RogerS Just uploaded the files for the two of you

Alternate download just in case

@MarkAnthony121 Downloaded your clip and get pretty decent igpu decoding in an 11900k. Won't play at 60p smoothly in vp20 but I made a proxy manually by right-clicking on media in 16 seconds. Decoding activity showed on the igpu in Task Manager. To use the proxy effectively for edit I temporarily set the project to 29.97 fps and the preview screen to preview-full. Played very smoothly and looked reasonably decent on my 4k monitor. A 13th gen Intel desktop cpu will likely be quicker.

If you want to go with a Ryzen or an Intel X-series with no igpu but more cores, an Intel Arc as a 2nd gpu could probably work as well if not better than an Intel igpu, so long as you don't implement devices that steal pcie lanes from gpu slots or shut them down... device trade-offs depend on specific motherboard/chipset design.

It's doubtful a 13900 would make a difference. My 12900 barely runs it without proxies. Most people I've run into have told me it's simply a Vegas optimization issue. The thing is I don't know if it's a strictly Vegas thing or a Vegas/Intel optimization situation. I'll know once I get a couple people testing this on their Ryzen systems. I'll literally switch to an AMD system if I'm able to play that footage on my timeline smoothly. Creating proxies works but doubles my workload. When I have 30 weddings to edit transcoding each one takes hours lol.

Running a 12900KS with 32GB RAM and a Radeon VII. Downloaded your clip - with AMD selected for decoding under File I/O it barely hit 2fps. Flipped over to the Intel GPU, and it played back in 4K at about 30fps full resolution. Dropped to Preview/Half and it played at 60fps.

Regardless, HEVC is not an edit-friendly codec. There's a lot of math happening in camera to compress that stuff down, and it requires a huge amount to decode it. I'm fairly sure if I threw one more layer of video in the mix Vegas would drop that framerate in half again. The HEVC thing has been debated endlessly elsewhere, and there's really zero reasons to use it especially if you can shoot all intra frame (which I believe you can on the R5 in 10bit 4:2:2). And yes, it will take up more card space and you'll need more media on set to deal with it, and cards are 'expensive' but you'll make that up and then some over a few months not wasting time waiting for proxy's and transcoding footage.

Wait, are you telling me if I switch to all-i in the R5 it should play back better and I just have to put up with the file sizes? Can't believe I didn't try this before. I don't believe it'll work but let me test and report back.

Don't see any indication of long gop in the metadata of your clip that I downloaded...

If you don't want to use proxies, suggest you consider shooting 29.97. I happen to be working on a wedding myself shot that way on a single xf605 and it edits and plays fine without proxies. And I was able to frame-grab better candid stills than the wedding photographer though his posed shots were much nicer. Just finished a music video project with two 4k cameras at 60p but had to use proxies for that... only shot it at 60p for some fast fingers on the keys which might actually have looked more impressive with a little blur... but no fast motion at the wedding with a dj. And video on the dance floor in low light was definitely better than possible at 60p.

Other things can help performance. Such as 3840x2160 framing. Also, most gpus can decode 4:2:0 in hardware. Intel definitely does 4:2:2 on 11th gen and later as well as Arc, but is still quicker at 4:2:0. I prefer to shoot 4:2:0 hevc on my cameras but I don't know if the r5 has a codec update for that yet.

What's long gop and why should I know about it? lol sorry not familiar

I think of it as the opposite of intra which compresses each frame independently. Usually the metadata tells you if the gop size is greater than 1. I just ran the clip through ffprobe and got 484 frames and only 17 IDR packets... I think that means it's not intra after all. Intra or N=1 is easier and quicker to edit but larger in size.

Correct, I always have been filming in IBP mode vs ALL-I. Last time I remember testing it, I couldn't even open ALL-I files in vegas for reasons unknown but I haven't tested in a while. I'll test over the next 48 hours how recording the exact same footage in ALL-I turns out. (Need to get a CF Express card as I can't record that mode on my SD)

Thank you @fr0sty for uploading that YT video - what a great overview/explanation about containers and codecs and ease of editing on the timeline. I've now subscribed to that YT channel.

It's also why investing in larger hard drives and some atomos recorders that you can connect to your cameras to record to prores is a better investment than dumping thousands into a new computer, assuming you already have something that is at least mid-range with a decent GPU. Not to mention the capture quality gains that make your video look better.

Yeah man, if I just learned that my 10bit CLOG3 60fps footage is going to play smoothly just by shooting in ALL-I vs IPB i'm gonna flip a table for not doing this for the past 2 wedding seasons lol. I'm over anxiously awaiting a CF Express card to arrive. I'm not holding my hopes high, but we'll see.

I would still consider eventually upgrading to atomos external recorders and shooting in prores, it decodes even easier than all i, is 10 bit 4:2:2, and has far higher quality than AVC or hevc because it is far less compressed. It should still support CLog and all that.

Not to mention the atomos ninja V also supports prores RAW recording out of some cameras, like Panasonic S1.

I'm pretty sure shooting prores for wedding is going to be unsustainable. I don't charge enough to buy a new drive each wedding lol. BUT....

@Howard-Vigorita It works!!! I turned off legacy AVC and HEVC, then for my dynamic ram preview I set it to 40% and turned off GPU acceleration. Slices through the CLOG3 10bit 4:2:2 ALL-I footage like butter at its max cap of 59fps. And about 45fps with a LUT applied. It only works if my hardware decoder is set to QSV on Intel UHD graphics 770, not my 3080ti or OFF. While it plays I see about 30% 12-900K usage, 30% 3080ti usage, and from 0-100% Intel UHD 770 usage. Rendering is WAY slower than before with the same settings but maybe I can tweak that. I certainly prefer a smooth stable editing experience. But it sucks taking 35 seconds to export a 15 second clip when previously with the IPB footage it would take 15 seconds. I will play around with it.

The Vegas video prefs setting should not affect decoding if you pick Nvidia. And should speed up editing, fx and lut processing. But Vegas behavior might be altered by a Windows setting in Windows/System/Display/Graphics. I add the Vegas app there and select high-performance gpu (Amd or Nvidia) rather than letting Windows decide... Windows usually picks Intel for power-saving.

Yep I've had my graphics settings for Vegas already set to high performance. But basically anything but these settings decreases editing performance. Everything is pretty flawless aside from the slightly slower rendering of my ALL-I file vs IPB. But yes, all those settings greatly affects performance. Changing to GPU acceleration with the 3080ti slow performance a bit. And selecting 3080ti for hardware decoding makes it almost unusable. The way I have it now is pretty much butter smooth full 60fps preview

I try your Canon R5 media, and playing the source media directly is ineditable, too much struggle (in my System 5-2021 - look in my Signature):

And create proxy is the only way:

We are almost in 'similar trouble' over here, as I currently need to rent the A7mkIV due to client's requirement of 4K-60p.

And, after looking several opt of recording format choices based on record data times in memory card and record setting quality, I ends up selecting XAVC HS 4K 100Mbps (it is H265 HEVC based as well).

XAVC S-I 4K choice? This is the intra-frame format - but overly-high bitrate🙈. not efficient in term of storage.

Quick test, had sluggish playback on the source 😵 - but after create proxy - much better. Hopefully during 'full-scale' editing, no much issue on the performance.
