I have some programs taped from DVB-T, which bear a rather intrusive logo, as seen here: http://img8.pixa.us/60a/19143931.jpg Above, in the top left-hand corner of the screen, is the old logo (the green one), which I would like to edit out, and replace with the new, less intrusive one, seen here: http://img8.pixa.us/405/19143930.jpg Is there a way to replace the logo on all of these programs (which I taped from this particular channel) with the one in the second screenshot? I'm looking for free software that can do this well, and hopefully keep the FFDShow codecs when the video gets saved (all have bob as part of the FFDShow codec). Sorry if this seems a bit long-winded, I'm new to video-editing! *edit* - images linked to since they are large, and they are only here for fair use/commentary purposes.
Depending on the video format, sticking another image over the logo is simple enough. If it was an .avi file I would use VirtualDub and the Logo 1.7b2 filter then recompress the file. If the source video is mpeg, it's not so easy.
The videos are stored in MPEG format (MPEG-2 to be technical), and what I'm trying to do is make the logo in the first video look like that of the second via some fade effect. I was trying to avoid the 95-07-20 part of the clip and any other date/time at top of screen being obscured by the green logo. Thanks for your help on the Logo filter, attar, it worked with avi files for me, I've tried that once before and it worked, but since it won't for MPEG files, I need to find another solution. Basically, it's fading the digital on-screen graphic (or some similar effect as seen in the second image that I linked to) that I'm trying to replicate. Sorry if this sounds a bit wordy but I'm new to this!
If you want to keep the mpeg2 format, I think you would have to use an Avisynth script in VirtualDub, then frame serve the output to an mpeg encoder (like Hcenc) - that's supposing that you could find a filter that would remove the original logo before applying the new one. It's beyond my level of support, but I would canvass around the Videohelp site and see what the experts there come up with.
