non-continuous logo removal (VirtualDub)
Posted: Sat Apr 02, 2005 6:04 pm
When I'm archiving old tapes I'd like to keep the channel-logo (mainly for nostalgic reasons), but I don't want to waste image-bandwidth on it.
I was able to remove the logo completely, but I wanted it to appear at the beginning of the movie, just for a short time so it can be seen - but NOT during the whole movie length.
Here's how to do a nice fade-in/fade-out logo:
1) get the filter "region remove v1.1" by Shaun Faulds.
2) Write down the frame number for the logo to appear
2b) Write down the frame number of the logo to disappear
3) Add the region-remove filter and adjust location & size.
4) Enable "Soft Transition" with 10 frames.
5) In the "Frame ON/OFF" field enter the frame-ranges like this:
If you want the logo to appear from frame 321 to 369 and your movie has 79000 frames, type:
voila!
PS: Due to missing documentation of this Frame ON/OFF feature, I had to read the sourcecode to find out the syntax - see? this is OpenSource in action!
