I need to put over the video prepared png text label. As far as I know I can use fade in/out filters with Adjust opacity button selected. I would like to use bar horizontal transition to animate the label. I tried to paste transparent clip before my text label and make transition but unfortunately only dissolve transition works on transparent clips. Lauren found a workaround with chroma key described in this thread:
But when I use chroma key it doesnt look that good and also its quite complicated way. Maybe it would be useful if you can set any transition at the beginning of the clip in similar way like you can create fade in/out filters - maybe just the possibility to change behaviour of the fade in filter? What do you think about it? Will it be possible?
