Motion will not show alpha in my 4444 file, I'm frustrated by motion....

The thing is, it seems to work on my MBP, but when opening the same project on my big MacPro, with ATI 4870 CARD, the alpha will not work at all. I get an almost black background.

No matter how I try the settings for file, it will never show me transparency/alpha. But it does it in the small preview thumbnail, but not in my canvas.

So what is wrong with motion and my ATI Radeon 4870 card....

Are you viewing properly in the canvas? Hitting SHIFT+T will make the background transparent for all layers containing an alpha. SHIFT+A shows black and white alpha channels, and SHIFT+C shows RGB color and is the default view in motion.

I found that sometimes on different computers I have different results with 4444. So my workaround is to render in Animation codec with Alpha + when this happens.

Yeas, I know the file will be bigger but, it will help you do what you have to do, without being IT technician....
I hope this helps...

Thanks for the tips, but going to Animation codec, well I would rather not... it slows everything down. The ProRes 4444 is made for more realtime, more moders codec and is much easier on my mac...

Hopefully the new Motion 5 will fix all this....:)

Yes, I view the file in the right manner... I can set all channels etc... and it works on my MacBookPro.
The file is made in shake, for a exr sequence, and works perfectly in final cut pro.

It's possible that the alpha was not interpreted properly by Motion. What do you get when you select SHIFT+A (show alpha only) in your canvas?

Here's something you can try:

Select the layer in the layers pane. Hit SHIFT+F to show media file. Go to the media tab in the inspector and look at what it says for alpha.

If Motion misinterpreted the alpha info, it might say none/ignore. You can try choosing Straight from the drop down and see if that does the trick.

Hi andy, It looks right in the inspector, with alpha and everything, but when put in the canvas/comp, it does not work, no alpha is shown...

But as I said earlier, it works on an other machine... but not this on... strange...

I found the bug....!!!!

My ProRes 4444 file only shows alpha/tranparency when canvas is set to best and NOT normal...!

When watching the alpha channel, all looks good in best mode, but when switching to normal, it all goes white....!

So here is what I know:

This BUG is on the following machines:
MacPro Model 2,1. Graphics ATI, Radeon X1900XT
MacPro Model 4,1 ? . Graphics ATI Radeon HD 4870

But works on these machine...
MacPro Model 3,1. Graphics nVidia GeForce 8800 GT
MacBook Pro Model 5,2. Graphics GeForce 9400M and 9600M GT

So what is wrong on my setups?

[Helge Tjelta] "My ProRes 4444 file only shows alpha/tranparency when canvas is set to best and NOT normal...!"

Thank you for that tip.

MacBookPro 2.6 GHz Core 2 Duo
Running FCS 3
OS 10.5.8
QT Player 7.6.4

When I drop my ProRes4444 movie file onto a track in a FCP 3 (7.0.2) timeline, the movie keys just fine as expected.
When I do the same in Motion (4.0.2), I just get black as the background. UNTIL I set my Render/Quality to "Best", then it keys just fine as expected.
