Problem with multiple alphas in Arena 7

Post by Gustavo »

Hello,

I use Arena 7.13.2 and I export my videos with Alley.
I have a problem when I place more than five layers with alphas (add mode with 50% opacity). The clip below seems deteriorate as if the alphas of the others layers add up. With arena 6 and exactly the same video, I never had this problem !
With Arena 6, I used to add up animation clip with black background (without alpha) and using the add mode, I was able to add up more than 20 layers without problem. With Arena 7, the black background appears if I add 3 layers !
I don't understand what have changed beetween arena 6 and 7 with the alpha interpreting ?

Any clues ?

Thanks you !

Hello Zoltán,

Thanks for reply.
I send a very simple composition with 2 columns with 6 layers :
In the first column, a clip with alpha. When I activate all the layers, the clip on the layer 1 is deteriorate. Why ?
In the second column, a clip without alpha. When I activate all the layers and I change the opacity ( always under 50%), the black background of the clips appear.
Why ?
With the same video, no problem on Arena 6.

Please help me !

Interesting,
Try adding a Solid color effect to the bottom layer, with Show Image enabled.
