Masks Not Transparent in Render? (Or other issue)

[NewYears1978]

This is a weird one. I am using AE CC for creating some simple text and line animations for use in Pro Presenter.

At Church we use iMacs but here at home I am on PC. So I am rendering with Quicktime, ProRes 4444, RGB+Alpha.

Now I was using Color: Premultiplied (Matted) and it was working fine. I could preview my videos in Quicktime or on the web and they imported in my PP6 just fine. But using Premultiplied as most know causes many issues (transparency weirdness etc)

So I switched to using Straight (unmatted) but now it seems all my videos are jacked up or the masks are showing colors or something on the web player or Quicktime.

however imported into PP6 they look fine. It's only local video playback or online playback. Makes no sense to me..cannot figure it out. Maybe it's a Windows issue?

Here are too examples - the first one you can see a white box that should not be there:

Dropbox - Worship Starts Soon - BOX REVEAL (Small).mov - Simplify your life

This one is ALL messed up, it should show animated lines and trans bkg but the lines are not showing up and everything is white:

Dropbox - Worship Will Begin Soon - ANIMATED BOX (Large).mov - Simplify your life

Here is the same one rendered just now with Premultiplied and you see it works fine:

Dropbox - Test.mov - Simplify your life

Super frustrating, any help appreciated.

this is normal. when you render straight alpha, the use is not for playback but for further editing or use in another editing or compositing software. what you are seeing is the RGB image that is then cropped by the alpha channel. it will look weird and that's o.k.

Thank you so much! I was confused. Now I know I am not doing something wrong

Appreciate it!
