Exporting Still TIFF with Straight Alpha causing weird reposition to upper left

[PaulK_]

So I have some toolkits that render still frames as TIFFs for Avid edits. The Avids like straight alphas. They all render out pushed to the upper left. Seems to crop to wherever the rgb data ends, but still maintains the full frame size, so it is like the element is completely repositioned up to the left. Strangely, this doesn't happen with premultiplied alphas, only Straight (try one quick, it's crazy). And it doesn't matter if LZW compression is chosen or not, etc.  

Btw, these toolkits worked fine with older After Effects (15 and below).

The solution is to render out TGAs, but I've always liked TIFFs.

Why did they change this? And can they put it back plz?

Hello, this does seem hardware specific, didn't happen on my laptop, so, hmmm...

Here are specs and screenshots:

After Effects Version 22.2.21
HP Z840 Workstation
NVIDIA Quadro M6000 24GB VRAM
Intel(R) Xeon(R) CPU E5-2660 v3 @ 2.60GHz 2.60 GHz (2 processors)
128 GB Ram
Windows 10 Pro (Version 21H2)

Any chance you've accidentally messed up the import settings on one system? I vaguely remember Avid having some weird import options. From the looks of it, it is cropping the visible content, which would confirm my suspicion.

Thank you, but this is a grab of the rendered tif file imported back into After Effects. It also looks this way in image viewers, photoshop etc. AE seems to be cropping it on render, but only for tif files.

Apparently this has been mentioned in other posts here as well, for tifs.

Ah, I see, so perhaps it's really a genuine bug. I guess TGAs it is then for a while now until this gets fixed...

Hi, just figured something out with this in case someone still has issues- when the project has CUDA graphics card accelerartion on the error happnes. When I go to File>Project Settings>Video Rendering and Effects>Software Only (turn off CUDA acceleration) the problem goes away and tif files are back to their regular placement.
