PAL DVD FLICKER

[Rafael Amador]

Hi Uli I need your adviced. I film a lot of images of trees and jungle and plenty of foliage. I use a Sony PD-170, sdo I get a lot of noise in this class of shots. I;ve tried the Boris CC3 noise filter but its mudds the image a lot. I’ve also tried when exporting to Compressor (the most of my jobs I finish as DVDs) the noise reduction filter (RGB and all channels) but even if I set it to the mininum the picture loose definition. What would you recommend me. As I told you I shot in DVCam but I color correct in FC and I also apply some chroma sweetening or deartifacter (MagicBullet) then I export from a 8b or 10b Unc time-line).
Thanks in advance for your help.
Cheers,
Rafael

Well, I’m surprised when you mention a lot of noise with a PD-170, from my experience it is a very low-noise camera. If you are talking about compression artefacts from DV, well, that’s another story. Hard to get rid of, if Magic Bullett doesn’t cut it, you might give Graeme Nattress’ film tools a try, but don’t expect miracles. Don’t forget to set the timeline to a better format than DV25 when trying such things, or you’re going to loose any improvement on export.

If we are really talking ’bout noise as in low-light situations, you could try two things:
– After Effects has a very good de-noiser starting from version 6.5 (ex Grain Surgery), slow, but powerful.
– BitVice, a MPEG encoder from http://www.innobits.se has a temporal de-noiser called DVNC, give it a try with a setting around 3.

Both are available as demo versions.

Good luck,

Uli

Hi Uli thanks for the suggestions
I have actually applied a gausian blur of 3 to it and seems to help a bit while making it broadcast safe. which obiviosly changes the colors of the logo a bit.
Is there a way of applying a vertical blur?

I covert it to a mpeg2 using compressor (for working on DVDSTUDIOPRO) and this I directly export from the time line of fcp. Do you suggest that I compress it to PhotoJpeg first and then take it to compressor?

thanks

In FCP 5.1.2 there’s a new filter that does a directional blur. A value of 3 sounds pretty high, BTW, but then I never use Gaussian blur for this purpose.

No, you don’t need to go the save as QT route, you can switch your timeline for a better codec and go directly into Compressor. But give those demos a try, there are better encoders than Apples.

Regards,

Uli

Uli,
Yesterday I had not Internet so I couldn’t tell you thanks. I ‘ve got a couple (many) questions to ask you, but not time in this moment.
Cheers,
