Even though under the transparency bar the value changes from 0 to 52 when you move the red cursor line in the effects animation window, in terms of visible effect, the value of 0 remains unchanged from start to finish.
Let me try to explain what I was trying to do. I have used a still and set the duration to 10 seconds.
I have applied a rectangular mask (with Mask inside unchecked, and a high feathering value)
Then I applied transparency which I wanted changing from 0 to 52 over the 10 second duration (key frames being the first frame and the last frame).
Basically, the value of transparency you set in the first key frame remains unchanged and the rest of the keyframes settings are not reflected.
If you are able to do it, can you please share the final video?
Sorry for bombarding you with messages...This is not working in v11.22 either. So my memory can't be trusted. https://content.invisioncic.com/r33241/emoticons/default\_smile.png
