Fuji big sensor 4k & 8k

Howard-Vigorita wrote on 9/20/2023, 4:11 PM

Been testing some clips in Vegas from a Fuji GFX100. 4k @ 60p and an 8K @ 30p. They're both hevc 4:2:0 10bit and I can't seem to play them well in Vegas without proxies. Ordinary Vegas proxies work fine on my 11900k system with Amd 6900xt . And on my laptop with Nvidia 3060 . But not very well on my Xeon with Amd 5700xt. On the Xeon it took using the Swap Video Files function in Project Media to play full speed. I swapped to a folder with 30p proxies I made myself using the Vegas Xdcam preset set to 1920x1080 30fps-progressive.

If anyone wants to try them out, the 2 clips and the proxies I made are in a zip:

It's 2gb so I'll probably only keep it up for a few weeks.

It's Vegas's implementation nothing wrong with your Nvidia GPU or it's decode. Interesting to see the Arc decoder working better on Vegas though.

You can see by the decode graphs what it should look like when working correctly in Resolve, in comparison with those jagged lines in Vegas which happen when Vegas can't process all the frames and drops them instead

@Former user I just tried in in Resolve and there are allot of settings to get it to match Vegas... had to change the timeline and display resolution to 8k. Did that and then disabled Proxies. Playback performance was very similar to Vegas without proxies. Enabling proxies gave it pretty smooth playback as in Vegas. Tried Prefer Camera Originals and it played as poorly as No Proxies.

It's interesting that Resolve defaults to an HD timeline and HD playback for high res clips. I think that's conceptually similar to using proxies in Vegas except you can choose the resolution. That makes it more like the Vegas Swap Video Files feature except that Resolve somehow does it more automatically and transparently. Maybe Vegas would also benefit from frame-size and frame-rate options specific to the Preview screen and independent of the project and render format.

What's also interesting is that the default Windows 11 Media player somehow plays this clip without much cpu utilization and no gpu utilization showing up in Windows Task Manager.

Yes Capcut does the same, you can change those defaults but it only matches frame rate, not resolution, but potentially unfamiliar users doing comparisions between Vegas/Capcut/Resolve could be comparing 4K/8K Vegas timelines with 1080P Resolve

What's also interesting is that the default Windows Media player somehow plays this clip without much cpu utilization and no gpu utilization showing up in Windows Task Manager.

Did you possibly play the proxy you created for your 8K30 instead of the actual 8k30 file?

My GPU decoder use in the media player is slightly higher than Resolve for the 8K30 HEVC

edit: Actually tried the default windows media player(windows10), I get an out of memory error for the 8K30, even though it had 20GB of ram to use. That is strange

Out of curiosity, I bought the Video Pro X14 from Humble Bundle for $25, sale about to end. I dropped the 8k footage on the timeline, and it played back smoothly right away on my computer (see signature).

I made sure that proxies was turned off. Now... what resolution is the playback, I have no way of knowing since I am new to the program. I haven't done anything with it yet to see what the performance is either, so can't comment if you grade/fx the clip how playback will be.

There is a lot of marketing talk on their website about the performance of the Infustion Engine 3.

@Reyfox

Hi, I've always updated MMS because I like it simplicity & stability, it'll do what i want with 4k AVC 8bit clips without a prob & the Infusion Engine did make it a whole lot faster, so sorry to be negative, I tried it on MMS (Same with VPX14.), I got the same result, initially really good playback but for me as soon as you started doing anything with it the performance slowly decreased to the point of stalling & making like an echo type noise. @browj2 knows VPX better.

I've always thought if the Lightening symbol bottom right of the Preview is off then it's playing the orig at full res, the help menu isn't clear about that, On this PC both this lightning symbol & the prerender often make things worse rather than better.

@Former user I checked to make sure Reduce Resolution and Playback were not check marked and the 8K clip played back fine once all the thumbnails populated the clip.

As for doing anything with that clip, I didn't. I kinda figured, once something was done to it, smooth playback would be lost. But using Ignite Pro 5 Cine Style, playback was smooth, along with using SeMW Auto Levels.

@Former user Same here on my Xeon with 128gb ram as well as my 9900k with 32gb, both win10. That same media player shows up in win11 as Windows Media Player Legacy and does the same thing there. The default win11 media player seems to be newer: Version 11.2308.3.0. So I went to the Microsoft Store and downloaded its free Media Player and it turns out it's the same version and works fine in win10.

Curiously, I just updated my 9900k machine to win11 but it didn't get the new Media Player. Had to download it from the store.
