clean text for video post production
Hi,

I have a problem with aliased text that I want to overlay over my video sequence in Blender. In the blender forum, they told me that the png file I created in Gimp has a 'far from being acceptable' alpha channel. (please have a look at attached png)

to be honest, I don't even know what does it mean?
all I did is to type some text and export it. and as a newbie, I have no idea what can it be done plus that....
what should I do more in order to get anti-aliased, clean text(and simple graphics in order to use in full HD resolution video)??

thank you very much.

RE: clean text for video post production
anti-aliasing is a boundary of semi-transparent pixels used to give a 'smooth' impression

Maybe try Layer -> Transparency -> threshold alpha and knock the value down a bit.

something like this, top is before, bottom is after.

RE: clean text for video post production
thanks for the replies.
I kinda found a work around. I first make text/logo on the white background then replace white with alpha before exporting. this gives a better result. I have no idea why but well...
