Hello, do someone knows a way to uncurve ( and or remove flicker ) from this knid of video taken off a Nipkow disc ?
I mean in order to have straight lines but not curved lines.

Thanks

I think a bendable perspex mirror could change the aspect ratio // it might uncurve a line .

The flicker your stuck via a nipkow .

Are you asking about how to do this to this particular video, or how to avoid it when constructing a televisor?

I just wanted to get some videos off youtube, and convert them for watching on the televisor. But if the picture is curved, and if I watch with a Nipkow disc, it would be curved again.
I wanted to know if a video-software can do somthing for it.

Well I suppose you could flip each frame horizontally, then when it is played back the two curves will cancel out (I think) and the curve will be straightened out - VirtualDub can do that for you.

edit: In fact a quick test on my MUTR shows that it does do so.
