unable to load *.mov file w/ alpha in v2.0

[hazardman]

as per title, i am unable to load quicktime files that has an embedded alpha in 2.0...i get a dialog box stating " Invalid File: [path\filename]"...

i would like to carry forward these projects in 2.x...other non alpha *.mov load without issue...

Hmm that's strange, because nothing has changed with the VideoFile module in 2.0.

Would you be willing to contact us on our contact page (https://magicmusicvisuals.com/contact) and send us a link where we can download and test your video?

Eric,

I did some further investigation. It appears the alpha support is broken with version 1.64, and 1.65.

The alpha works fine in version 1.63 (the version I originally used) and below.

I know for sure that alpha support is working overall in 1.65 and 2.0, because I've tested with many alpha videos.

It just seems to be the particular codec you are using. Not sure why it worked in 1.63 but not in 1.64, so I will investigate .

I created/embed the alpha data using AfterEffect but I don't recall the exact setting I used when I exported as a quicktime but I believe I used *.png.

If it helps any, here's the detail info of the video file I was able to get from Premiere:

eric, i did some tests and going with the "animation" codec instead of "PNG" did the trick (albeit creating a much larger video file)...

all i need to do now is to re-encode with the former codec setting...still, a bit strange that "PNG" works on the earlier versions but at least I know how I can move forward

Yup it is certainly strange. I'll have a look.
