Glad you found that, but I think that is a short-term solution. For example, the FXAA/TXAA shouldn’t cause such a big change in the DOF.
I suggest… For one thing if you set it to TXAA in a Post Process Volume and set Screen Percentage to 150% or 200% you’ll find a nice blend of crispness and softness. You should also tweak the DOF in the Post Process Volume (make sure it is “Unbound”) and Matinee should render it accordingly (unless there is another Matinee overriding it).
Hence, I propose the “Master Post Process Volume” technique.
Firstly check that the “Engine Scalability” in the Editor is always set at Epic. UNCHECK the “Monitor Editor Performance” as it can suddenly turn down the quality settings.
OK, now what I like to do is turn OFF all the default Post Process in the Project Settings.
Then I set a new Post Process Volume and set the Priority of that very high (100 or 1000, say). Make sure it is Unbound.
This way I know it will be the “Master” Post Process Volume and I go there to tweak all the settings like DOF, TXAA, etc.
Be sure to also set the Screen Percentage to 150% or 200% if possible (A kind of SSAA (Super Sample Anti Aliasing)). I find that TXAA with SSAA gives some superb results.
TRY: When exporting out of Matinee ensure you export out of Matinee to PNG frame-by-frame (preferred) or to movie at the proper specified resolution.
TRY: Exporting PNG from Matinee at 4K then create MP4 using FFMpeg, downscale to 2K, 1080p, etc.
TRY: Use Nvidia Shadowplay to record with suitable TXAA and SSAA settings.
I don’t mean to blow my own trumpet but I am passionate about rendering the best out of Unreal Engine 4, check out this DX12 4K export from Matinee (scene by Liam Tart from Marketplace):
For the “Showdown VR” from Epic Games from Marketplace, I went in and re-lightmapped the scene and added a “Master” Post Process Volume (and tweaked a PPV in a Matinee Actor that was causing overexposure). I imagine for motion graphics the “Master” PPV will be crucial in getting the scene you want, including as I suggest SSAA+TXAA if possible, FXAA will still cause antialiasing issues. I’m only on an Nvidia 660M and this is a screen capture so it’s only 1080p, you can download the higher-quality 1080p MP4 in the video description:
If any experts can sound in, that would be great. Cheers.
