Ah, sorry!

Should have been more precise. I’m not after doing AUDIO noise reduction, rather VIDEO noise reduction.

Any tools for that in FCP? 🙂

There is a video noise removal filter in the Filters Pane in Compressor.

I think I would encode at full frame size, rather than throw away any more data.

[Niklas Wikman] “I’m also thinking of encoding MPEG-2 with 352×576 resolution, instead of 702×576. Then the DVD player will automatically scale the picture. Since it*s VHS, I figure there’s no point in encoding at 702×576 anyway. “
To clean the noise of a movie is a waist of time when you intend to do such destructive capture.
When I work with a low quality source I try, at least, don’t degrade it more.

You misunderstood me.

I capture at DV25 720×576.

My idea was to encode MPEG-2 with 352×576 instead of 704×576. There’s really no need for full resolution since you have already lost that much from the original VHS footage.

I’ll have a look at Video Purifier and the free Noise Reduction suggested here.

I think that what Rafael was trying to point out is that you’re converting a low quality analog format to a highly compressed digital format with low color sampling- DV. You’re only going to add compression artefacting to whatever other problems you already have. It would be better to capture it to an uncompressed or less compressed format like ProRes or DV50.

Hi Arni,
Niklas want to make a ‘half size” DVD because he thinks that the source is already of low quality.
In the other hand he want to de-noise the movie.
For me, sorry, this makes no much sense. He cares about the noise but not about the picture being blow-up by a DVD player.

[Rafael Amador] “Is like if you brush the hair of your dog but you don’t feed him.”

That’s a great analogy! I’m in complete agreement. If he want’s the best quality, he can start with a better capture and should end with a full height DVD. It won’t be the same quality as a studio picture, but I don’t see the point of putting all that effort into NR when you capture as DV and end up as half height.

FWIW, I’ve made half height DVDs when I needed to fit around 4 hours on a disk, and it did look better with that much compression than the full height did. But at more reasonable (and typical) compression levels, the full height is waaaay better.
