Two Videos Over Top of Eachother (Transpose, Overlay)??

[christopheramos]

Hello,

This is kind of a hypothetical and a question at the same time. Say:

1. A person has a TV show with logos at the bottom that they want to remove (I know, it's almost impossible to do without making the video look smudgey),

2. The person had two versions of the same show. One with the logos only on the bottom, and one with logos only on the top,

3. Wouldn't it be neat if a person could transpose those two videos together, and sync them up, so in the end there are no logos. In other words, overlay the top half of the one without the top logos with the one without the bottom logos.

Would that work???????

Thanks!!!
Chris

Easily done in almost any .AVI editor..If you don't have the money for the higher end NLE's, then you could learn AVISynth, to do the same thing...

I must admit, i've never seen anything in your instance..It's quite odd...

Hi Pijetro,

What's odd about it? The fact that this is a different way of trying to remove logos, or the fact that I have two different video sources with logos in different places?

Thanks!

as long as it's the exact same video it should work without a problem. hopefully both are in the digital domain and one is not slightly slower than the other. provided this is the case you should easily be able to sync them up, strip away one of the audio tracks..then use the top of one and the bottom of the other..i believe virtualdub would do this...

[christopheramos]

Wow. So my next step is to try to figure out which program to use to do the job. If I have to spend a lot of time getting to know a program, I hope will do the job. Otherwise I'd just be wasting a ton of time. You know? So virtualdub and AVISynth ????? I am not familiar with either of them. So I don't know which way to go.

If you're not familiar with scripting, I'd suggest the Vdub and see how it goes.
An easier way would be just to cover the existing logo with another.

yep...there was a guy who actually did sort of what you are wanting to do in virtualdub but he split the screen down the middle vertically. He basically wanted to make a video of him talking to himself. So he stationed a tripod somewhere..shot both takes then combined the left and right side together.

Yeah, that's the one...

What other software do you have in your arsenal??

Well, I have DVD Lab Pro, but I'm still trying to learn the very basics of it. I'm still a newbie, unfortunately. Would DVD Lab Pro do the trick ????

There is a program called VideoEditMagic that might do what you want. You would need to put a blue screen on the top of one video and then overlay it on the other video and use chroma key view through the blue screen to the bottom video.

There is a 30 day free trial...

I used an older version for a while and it had alot of useful functions like joining different file types and resolutions to the same project.

Well, that will compile your assets together. It's an authouring program. Basically it puts all your Lego blocks together to make a building...
Unfortunately, that won't help you.
You still need to use an .AVI editor to do this task...

It's a pretty simple matter when using AviSynth to frameserve to an encoder. Say you have one video with the logo at the top, and another with a "clean" top. You want to crop away the bottom part of the second one and then use it to covers the logo of the first one.
If both are AVI:

main=avisource("C"\Path/\o\Video1.avi")
pip=avisource("C"\Path/\o\Video2.avi").Crop(0,0,0,400)#Adjust if necessary
Layer(main,pip,"add",255,0,0)#0,0 are x,y coordinates. Adjust if necessary)

I called it pip because the effect is similar to a Picture-In-Picture. If they're MPEG-2s, then you make D2Vs with DGIndex first and use MPEG2Source instead.
