Export With Transparency ERROR

[Diogo3296508465lf]

i, Im having trouble exporting and rendering with transparency, I did it as I always do, with QuickTime in Animation RGB+Alpha, but it's not working, i've tried AppleRes4444 i've tried GoPro12 +Alpha, nothing works!

When I try to open it with VLC it either doesnt show or the colors are completely glitched and off, when i send it to iphone it doesnt open the file.

Can someone help with this?

This is how it looks when i see it in VLC, but It doesnt open in Iphone Quicktime

I hope that this isn't a silly question but have you double checked with the transparency grid button that it is surrounded by transparency?

Try using the Render Quque/Output Module/High Quality with Alpha preset. 

The Animation Codec is deprecated and no longer supported on many platforms. Unless you have a lot of experience with video formats and compression rates, it is always a better idea to use the Presets in the Media Encoder and the Render Queue than fiddle with settings if you don't know exactly what you are doing.
