We do a lot of virtual production and we would really like to testdrive UE5 for some simpler composure comps because of the better lighting, performance etc. with UE5.
We got every plugin in beta for the UE5 we need to accomplish great results but unfortunately the MEDIA_BUNDLE is not working properly.
We are using a Decklink 8K Pro - the SDI-IN is a stable FullHD Video. If we than drag&drop the MediaBundle somewhere in the scene, it stops playing afer 10 seconds, somtimes after 2 minutes and sometimes if we click somewhere in the UE window.
We tried different PCs with different Decklinks - we always got the trouble, that the SDI-Input-Video stops playing after a random amount of seconds or after we do some actions in the gui.
If you like to debug and recreate this bug:
To speed up the effect, so that the video stops earlier, than try to use 2 MediaBundles with 2 different Video-Inputs via SDI. One or both of the Videos freezes after a certain time.
Is this a Plugin-Problem of the Blackmagic/UE5-Plugin or is this a UE5 Problem?
We can run 4 different 4K Videos with 4 different MediaBundles without such freezes in UE 4.27.1.
Please check this one - otherwise UE5 is currently not suitable for virtual productions with live video-inputs via SDI.
PS: We use the 1st SDI-IN for the Color-In of a green-screen live recording and the 2nd SDI-IN
is the ultrafine matte coming from an ultimatte live-keyer.
Either the ColorIN stops playing or the MatteIN.
Hi @JerryDOCK11,
You may find you need an upgrade to your PC.
The minimum spec is
8 GB of VM, and 32 GB of RAM. 12-core CPU at 3.4 GHz for 30 frames per second, Nvidia RTX 2080 or AMD Radeon 5700 XT, and 64 GB of RAM are estimate
The PC which will run 4.27 will not usually run UE5
you MUST have an 0.5GB SSD/NVRAM boot drive to stand any chance of using the UE5-release. This is more critical than a super RTX graphics card.
If you cannot complete this on your current PC may need an update/replacing and it’s the test Epic used to test UE5. I added a 64GB page file.
This is just my opinion but I have built and used the * Virtual Studio learning example easily, but In-Camera VFX Production Test took a long while to get working.
Binary 5.0 EA2 may not work and that’s why you need to build the source.
I assume as a company you want a stable release, well this was sort of stable on 30th October, but later releases are more unstable, they won’t build! sometimes.
Your PC Spec seems to meet the requirements
I really don’t know what to say its a moving target! with UE5 and the only official version is 4.27
I’m having this exact issue with an AJA to usb3 right now. The video in will just randomly freeze. I’m still in 4.27 as I’m just testing. It’s been a couple of years so surely someone has found a solution?
