Problems finding HOW to do a 16bit export.

[Chris Wright]

trillions of colors is 16 bit/channel or

16×4=64bits in the tiff, and turn lzw off too, its lossy.

[Michele Poggi]

I did put Trilions of colors in the export that gave be (in the Tiff) 24 and 32. That’s my issue.. I’ll keep testing and trying though.

[Michele Poggi] “The TIFFs I then open says “24bits for channel””

Exactly! 24 bits per channel: 24 bits for the red, 24 for the green, 24 for the blue. You could even go higher than 16 bits and the 24-bit setting would be able to handle it!

Thanks for the support guys, I talked with the VFX Supervisor and he told me this (ours) was not the case.

He’s using XnView to check the depth because it seems that XnView shows the TOTAL even if it shows “per channel”, so showing 24 it means 8 per channel. That’s why in the first post I was talking about “8×3”. I know it’s weird, but since he’s actually using that as official test, maybe my AE is indeed making errors or is this program somehow the fault?

Is there a way to fully be sure about the color depth of the TIFFs I’m exporting.

As always, thanks, and I hope to be as useful as you to this community, asap. 😉

[Chris Wright] “turn lzw off too, its lossy”

Really? I think LZW compression is lossless [link], and a quick test render of noise as TIFFs with and without LZW compression shows no difference for me.

XnView downsamples TIFF files to 8-bit RGB when it opens them, but it does correctly report the bit depth when browsing.

If your output module is set for Trillions of Colors or Floating Point, you should not be getting 8-bit files.

You could try re-importing your TIFF files into AE, then selecting one in the project panel. If it says Millions of Colors next to the thumbnail, it’s 8-bit. It should say Trillions of Colors.

Otherwise, maybe if you post one of your TIFF files, one of us could check it for you?

Sure, here it is: 3629_00043.tif.zip

The VFX Supervisor began having doubts because of the circles of contrast that are around the sea. And then checking on XnView he said that since it was showing “24” the files were 8 bit. Then forcing in the output module the 16 bit export (though it should have been already ok since the project IS 16 bit and by standard there is “current settings”) it showed “32”.

Looks good here. Here’s a screenshot of XnView showing 48 bits (per pixel):

I usually don’t use XnView, but I downloaded it now to discover what in the world my supervisor could have done. Of course I confirmed what you said, so it IS 16 bit, indeed. Exactly as you said if you open it it downs it to 8-bit, so maybe my supervisor missed this thing and looked at the wrong properties. I’ll warn him.

Thanks for the extremely fast and professional support, really.

You’re welcome — and good luck with the project.
