Does Visualize 2017 professional have the ability to output Alpha Channels in movie files? Tried MP4 but After Effects does not see the Alpha.
Hi Jonas ,
I have also attempted this and the Alpha option is able to be selected when creating an animated movie in visualize , this is a great question for Bastian Krueckberg
I just noticed that, it creates a separate folder with a Tiff sequence of the animation. The Tiffs have a transparent background but still no Alpha channel. It workable for me, but not ideal.
I have not tried this in Visualize but I assume if you save your animation as a sequence of images (not a video file) and choose a format that includes alpha (png, tiff) then AE will use the alpha channel in the image. This is the way it works in many other rendering packages.
we currently do not support alpha transparencies in movie formats. I'll note this as a requirement/feature request.
As mentioned here already, the workaround would be to render the animation as an image series, choose a file format that supports alpha channels (i.e. PNG or TIFF), check "Inlcude Alpha" and then encode the movie in another application.
Also, I am unsure though about what @Jonas Concepcion is saying when his Tiffs' have a transparent background but no Alpha channel. How is that possible?
It's possible @Bastian Krueckeberg. This is how Photoshop and after effects interpret the Tiff straight out of Visualize
The confusion is that under the output tools when rendering a movie. The image format option is greyed out with Tiff selected. I understood this as that was not an available option. Instead the software creates a separate folder with an image sequence.
the "Include Alpha" options is respected even if you render out a movie. Now unfortunately, this movie won't be transparent but the series of TIFF images, that the movie is based on, will include an alpha channel.
Your screenshot of Photoshop puzzles me. If there is a transparency in the image, this information must have been taken out of the alpha channel within the TIFF. Maybe there is an option in Photoshop to change its alpha/transparency handling?
I checked the same with Gimp and Photoshop myself and I am seeing the result as expected (see screenshots):
Yup your screenshots are what I would expect to see and is what I get when Tiffs or Targas are saved from Photoview360.
Would you mind sharing this TIFF file with me so I can take a look at it?

Thanks Jonas. This image looks OK to me. It has 4 channels (RGBA). See following screenshot...
Top: Alpha channel enabled
Center: Alpha channel disabled
Bottom: Alpha channel only
That is odd. It may be as you say that there is issue with Photoshop handling the image. It's the only editor I have at the moment and like I mentioned. Files from from PV360 would come in just fine. It's not a roadblock at the moment so I can't spend too much time digging into it. Thanks for reviewing.
I installed Photoshop CC and got some more background info on this. It looks like Adobe has decided to change the way it is interpreting and displaying transparency information and alpha channel data.
You should be able to workaround this in the following way:
1) Open image in PS
2) Select Layer in Layers window
3) Choose Menu > Layer > Layer Mask > from Transparency
4) In Layers window, select and right-click on Mask and choose "Disable Layer Mask"
See following article on this from Adobe:

This relates to Alpha channels on a static render. This is my first render since I upgraded to Visualize Professional 2017 SP3.
I saved as PNG and as TIFF. When I view the files in windows picture viewer, the "include alpha" renders have NO background.
But if I view the files using Irfanview64, the TIFF "include alpha" file does show the background.(I do not have Photoshop.)
My understanding is that the Alpha option just allows the background to be turned on & off. But that both settings should still display the background.
Did something change with SP3 or is this the first time I have noticed this?
Confused (so what else is new?)
TIFF versions are too big to upload and Zip only compresses them to 99%. I can share via Dropbox if anyone wants to see them.
