+Vegan Pop Tarts Virtualdub. I'm using a filter called logoaway. It does a pretty good job but unfortunately all it does is blur out the section where the logo is. If I REALLY wanted to put in the effort I could do a close to perfect removal but it would be quite a bit of work.
+Uncutcartoons247 I guess what you could do is if it's just a sort of white transparent logo text, you can make an effect that's traced to be only over the text that darkens it back down.
I did a logo removal on Impatient Patient with Daffy Duck before. I used PowerDirector 13. I put an image of a frame without the logo into MS Paint and cut out the area of the frame where the logo would appear in a few seconds. Then I pasted it onto the movie clip as a Pip object. The finished product is hard to notice, but it kindof looks like a moving box sometimes because the cartoon is a little shaky. The whole thing took about 2 hours to finish for a few seconds of film. :/ I tried to use a trial logo removing program for it, but it just screwed it up. I can't even tell where the logo was for this Blackie Lamb cartoon you fixed here, so I'll have to look into those programs. Many thanks for the info. ^^
