I am desperate to find a preferably free download of software for video noise reduction in iMovie 6 or Quicktime dv or mov files. This must be useable on OS X 10.4.11.
Can anyone come up with an answer or suggestions?
Many thanks

I've asked the hosts to move your post to the 10.4 OS area so it will be read by people actually using the older software.
When you say 'video noise', do you mean pixelation from low-light photography?
iMovie 6 has a number of video effects, listed in Editing. Fiddling with the brightness and contrast can sometimes improve matters if you darken it a bit.
What is the source of the video? What do you actually see in terms of noise?
The iMovie forum would have been fine. I am not the only iMovie 6 fan posting there! 😀
The post originally was in the Intel iMac forum...... and I couldn't make up my mind if it should be in Tiger or iMovie, it was a dead heat.... 😀

Terrific discussion so far! Sorry if I didn't plant this in exactly the right place.. (there's so many options!)
OK, the problem I have Klaus is film grain. The piece I'm working on was originally shot on high speed 16mm film stock (20 years ago) to give slo-mo.
I've now made it even slower using iMovie 6 fast/slow/reverse effect, but this unfortunately enhances the grain problem as every speck moves slower..
I used the bright/dark to darken it for other reasons which again made things worse.
I've used 'Neat Image' to great effect on static pics but all I can find by them for video ('Neat Video') has to work through either Premiere or FCP.
So...I'm hoping someone has an idea how I can clean this up in iMovie 6 (or a QT file?), without losing definition.
...and PS, yeah, I think iMovie 6 is terrific.

😮 Well. Really. Hmmm. I see.
(Getting even will be so much fun!) 😁
@ prof d hall:
I use iMovie HD as well, but it does have its limitations as far as editing/enhancing possibilities are concerned, but maybe Klaus has an idea.
As I see it nothing can be done about the quality of the original film stock (short of re-processing and feeding each frame through Photoshop!), but much depends on how it was digitised, which for movies is an expensive excercise. We are not talking about analogue video-8 here.
Digitising movies is an art form. Ideally each frame has to be digitised one at a time so that the settings can be 'individualised'. Digitising old commercial movies for DVD distribution costs millions.
As for iMovie 6 and its successors it is a question of 'GIGO' - Garbage in, Garbage out.
How was the 16mm film digitised? Was it done to your satisfaction? Could doing it again improve matters?
Thanks Klaus
Not surprised by what you say, a pity. The original film was grainey but not so apparent. When transferred/digitised it was still apparent but as explained:- having slowed it down further recently (and intentionally) it seems to show up more. I dont think re-digitising would help.
I would really appreciate hearing if anyone else has any ideas/views on this..
Yes, slowing it down even more will do that, as you are looking at each frame for longer.
Video noise reduction for iMovie 6 or QT files?
