Compositing Mode to Eliminate VHS noise

johnmeyer wrote on 10/1/2003, 5:23 PM

I have captured a VHS tape twice and saved into two separate files. I put these above each other on two tracks, and align them exactly. Thus, I have two separate versions of the exact same tape.

Why?

Each time an analog tape is played, the random noise ("snow") is in different places. What I am trying to do blend two versions from two independent captures in order to get video that has less noise. What I want to do is come up with a composite that is the exact average of both videos, and which ends up at the same intensity level.

Any idea of how I can do this?

Did that. I see the Satish Pluginpac when I open Vegas, but I am not sure how to load the Virtual Dub filters. They aren't listed.

You need to use the Add button within PluginPac to tell PluginPac where to look for the filters.

I actually tried that before I posted the above and it crashed. I think I'll start from scratch and download the plugins again. Thanks for all your help John.
I am curious to see how this works since my source was not VHS, but rather DV to begin with. Completely black backgrounds with spotlit singers moving around amidst the black background is a nightmare that only artsy stage lighting people can appreciate. Then they expect a VHS copy to look the same as the naked eye sees it live. It's been a lifetime battle, but I do love shooting stage productions because I love theatre. My proc amp works well much of the time placed between my duplicating rack and my source deck or computer. There is a lot to be said at times for knob twisting, but I would like to compare the two so thanks again for your help.

There are a few plugins that will cause PluginPac to crash (SpotRemover for example).

Also, temporal plugins (that require more than one frame of video) will not work.
