I’m having trouble getting the Video Sequence editor to properly overlay an image on top of a movie strip. I’m just trying to put some explanatory text on a little educational video.
I’m putting the text (saved as PNG from GIMP with an alpha) and putting it above the movie clip. When I select “Alpha Over” on the image strip the movie shows through, but the text isn’t properly anti-aliased (the text isn’t as sharp as it appears in GIMP).
So I suspected that I wasn’t saving the PNG correctly, so I thought - I’ll just render something simple using RGBA from Blender itself and give that a try. I used the default scene and just rendered it to PNG with RGBA and then tried it. I could see the underlying movie clip, but it was washed out.
It appears that the “color” in the alpha area is somehow bleeding into the “color” in the underlying strip.
I can’t imagine there isn’t a way around this issue, but I haven’t been able to figure out how to do this. It would seem anytime someone wanted to add some rendered material to a live action clip they would run into this problem, so I’m sure it’s just something I’m doing wrong.
Thanks for any help.
BTW I first noticed this on 2.59, so I upgraded to 2.61 and had the same problem.
