Tool to reduce interference lines

Hello,

I'm looking for a tool which will enable me to get rid of interference lines. I am currently editing a 1hour DVD that includes a lot of in-car (F2, F1 etc) camera shots. However some of the footage I have been given has Interference lines caused by the engines electronics.

Does anyone know of a tool that will reduce the interference.

Any help appreciated!

Cheers,

No takers?

I have been playing around with virtual dub, but thus far its not worked. Got a feeling that this won't be possible, unless itís done by some kind of professional video restorer.

If anybody knows of any filters for Virtual Dub, plug-ins for Premiere, After Effects or any other program please let me know.

Cheers,

Keyframed color correction (you would need to make a mask, of course) or rotoscoping would be my approach. I know of no specialized plug-in.

What you are looking for would be the equivilant of an impulse noise reduction filter for video. Sadly, I know of no such tool. They exist for audio. You might hunt down Graham Nattress. He's a filter guru for FCP. He might have an idea for you.

I'll be trying RE:Fill by RE:VisionFX. I'm downloading the demo tonight. It is only $99 and is a plug-in for After Effects.

I'll be trying it on old analog footage that has dropouts. You might want to try it, too.

Check it out here:

Hi Guys, thanks for your replies!

I had a go at using RE:fill, but it seems to use mattes as a way to determine where the scratch is. As interference lines appear all over the screen randomly, and so quickly, itís near on impossible to reduce the appearance of the interference lines.

Thanks again.

I haven't been able to use it too much but I got to a point where I was able to just get the white lines from video dropout and the blownout highlights to show up on the screen. If I had saved this as a video, I could've used it as a matte to fill the same glitches in on the actual video but I was pressed for time and I was using it on someone else's computer.

You can also try AVISynth's Convolution3D filter.
