NextPreviousHomeLow Quality with Alpha Render



EricB | 2 years ago | 6 comments | 384 views

When I include alpha channel, the resulting image looks blocky and pixelated, but the preview is totally fine.

What could be causing this?

I tried updating the Nvidia drivers for the Super 2060, uninstalling and reinstalling Blufftitler..

The only render that seems to look proper with alpha channel is Prores 4444. BMP pictures and PNG image sequences are blocky.

I converted the example to jpg in order to upload it here. But it's from a png with alpha channel.

Does this look right? I must be missing something.

Thanks

Here is what a 4K super high quality looks like on export (from screen capture). But the preview is super smooth. I though perhaps it wasn't saving enough bits for the alpha channel, but it seems to be 32 bits..

A quick update, I had some minor improvements with various settings in the NVidia panel. It seems also this may not be as related to alpha channels as I thought.

I'm still finding it impossible to get a render that looks as good as the preview.

During export it looks bad in BluffTitler because the export resolution rarely matches the resolution of the render window. The goal is to generate the picture/video as fast as possible in the highest quality without wasting precious time and memory to make it look good in the render window of BluffTitler as well.

After clicking the OK button in the "Picture successfully created!" dialog in your screenshot, the jaggies will be gone in the render window of BluffTitler and also not visible in the generated picture.

Thanks Michiel for explaining that. It definitely had me confused haha.

The renders look great, here is an example at 4K 60P.
