Reducing Video Noise (colored grain)

Is there a way to reduce video noise in FCE and if so, how?

I'm a little surprised since it is such a common problem in video taken in low light. I currently use Pinnacle studio on the PC side, which is a little more robust then imovie but far from FCE, and it has a pretty nice noise reduction filter which cleans up the video considerably. I took a poorly lit video clip which I was able to easily clean up in Pinnacle, into an apple store yesterday to see if I could clean it up equally or better in FCE and could do quite a bit except for the noise reduction. I'm doing this test due to my interest in switching to a Mac, mainly for video reasons. Are there plugins that could help with noise?

Reducing Video Noise

I have a short clip that was shot in poor lighting. Is there something in video effects that will allow me to reduce the graininess?

Hi Sheldon,
You can remove the video noise using Remove Grain effect.

Hope that helps!

Reduce video noise -Final cut pro x

Hello People,
I filmed some clips in low light conditions... so the footage has some video noise.
Do you know a method to remove the noise?
I have Final Cut Pro X and Motion 5...
Please write me soon, Matteo.
PS: I'm Italian and I don't understand Englishe very well..... sorry!

Ciao Matteo,
The best video denoiser I've used is Neat Video:

It's really quite magic!
According to their website, it works in Motion 5, and there's even a free demo you can try.

Can I reduce video noise in iMovie 11 (a.k.a. random pixels)?

My video has a bunch of random pixels, and can I get rid of them using iMovie or other free software!

In Final Cut Pro X, you can do this automatically through the multicam feature. You can also adjust the audio to the 1/100 of a frame.
In iMovie, you should turn on the wave forms of both the movie track and the Zoom track. You should be able to visually see the spike of the clapper sound. You can manually drag the audio track so it lines up with the video track. In iMovie, you can adjust to the nearest frame (not 1/100 of a frame).

How can i reduce the noise on this video?

I have used Keylight to key some chromokey footage onto a white background.
However, I still have a lot of noise on the video, by this I mean fuzzyness, instead of good rich colors - you can see for yourself if you download a sample of the file which I have linked to here:
http://www.youtube.com/watch?v=-MmBGI-JUMk
Obviously the actual file has proper dimensions unlike the YouTube example! This example also doesn't show the noise quite as well as the actual Flash file, it's a little more intense than it looks here.
How can I make the video fuller in color, to reduce the noise....?
Thanks.

The noise looks like genuine camera noise from poor lighting with ramped up sensor sensitivity. Therefore, as a start, I'd run the clip through a pre-comp and use the Remove Grain effect or tools like RevisionFX' DE:Noise, Red Giant's Key Correct Pro and so on. If it's DV/ HDV or similar, some de-blocking by ways of similar tools is also recommended. This should already improve matters notably. Then, as Sébastien said, study the super tight junk matte tutorial and apply the technique to your footage. The less pixels to key, the more efficiently the keyer can expand its range on the remaining ones. If you then still experience jaggy/ noisy edges a second application of the aforementioend plug-ins might do the trick. Other options include tools like Twixtor, SmoothKit, RSMB, RE:Fill etc. to mend holes and smear gaps. also, since the person is wearing dar clothes, the old trick of using a dark Inner Glow might also be applicable.

Video noise / grain reduction

There was a previous discussion on grain and noise reduction but I believed it expired. What filters/ plug ins/ other apps have people used successfully in reducing grain and video noise?
thx

There's some great thoughts in this thread:

Video noise reduction software?

Sorry... but I've asked this question in the Tiger OS forum about video noise reduction for iMovie HD 6 and/or QT files but haven't got far with it.
If anyone on this forum has any suggestions about what I could use to reduce visual noise - basically transferred film grain in digitisation, I'd really appreciate it
(better still a free software download or trial would be even more appreciated)?

I'm not aware of any free good denoiser.
Neat video has a trial, but I think it's either watermarked or limited to SD. But it is really good and the trial will give you an idea of what iyt can do and whether it's worth the outlay for your purposes.
Another option is Adobe After Effects. A bit of a learning curve, but they have a trial.
Good luck.

Adjust Video Noise

So I would like to adjust some video noise of a clip recorded in low light. Any suggestions? I searched and found an addon called neat video but not working correctly. Any info greatly appreciated on how to adjust this video noise. Thanks

Actually I am looking at answers for both. When I posted this topic, I was originally looking to adjust video noise to several clips recorded in low light. Then I came across once clip, where the background audio noise is too loud where you cannot hear the person speaking. It happened to be when I responded, I was so caught up on the audio noise reduction search that I forgot what my original topic was all about. So yes I am looking at adjusting both, video noise recorded during low lights and reducing background noise on a clip.Thanks again and I apologize for the confusion... I can post a new subject for audio noise...

Video noise in exported blu-ray

Hi - I don't know where to start with this one. I exported a project from PPro to Encore for menus, etc, and built a blu-ray ISO image. So far, so good. I burn a BD-R from that image using imgburn, then I took the disc upstairs to watch it on the big screen, and YUCK!
Before I go on, here's the details:
Win 7 Pro SP1
Core i5
8GB memory
200 PATA for OS, programs,
500GB SATA for media
500GB for scratch disc, etc
1TB e-sata for backups
Production Premium CS5.5
PPro 5.5.2
i have CS6 waiting, but I want to finish this project before installing CS6.
~2 hour film of a stage musical production, plus a bit of behind-the-scenes/backstage stuff
Footage from 2 x Sony Z1P cams (1440x1080 1.33 HDV), and 1 x Canon XF300 (1920x1080 1.0 - I think it uses XDCAM)
Due to the nature of the stage lighting, i.e. lots of deep colours, this footage needed a great deal of colour correction and frequently needed big boosts to brightness. I mainly used the RGB colour corrector, as it was easy to boost or reduce the red, blue and/or green gain to get a reasonable result. I was mostly trying to return skin tones to something resembling human, and leave the rest of the colours alone. Sometimes I needed to use "Change to colour" because the lighting crew used a different colour backdrop from one night to the next
I used brightness and contrast adjustments to start, and played around with gamma and overall gain to fine tune the brightness. Also had the reference monitor on display - mostly RGB but also YC waveform.
Anyway, playback in PPro looked OK, I thought it was as good as it was going to get, so I added chapter markers, exported to Encore, built the menus, FINALLY got a clean bill of health from "Check project", built a blu-ray ISO image on the hard drive, then burnt a BD-R for testing.
Took it upstairs to the lounge room (where the blu-ray player, big screen and audio systems live), loaded and started to play. The menus look and work OK (buttons, scene selections, etc). Here's the strange parts:
1. the footage from the Canon and ONLY the Canon, appears to have had a lot of noise ADDED (video noise, not audio). This was the first time I used this camera, and I noted that when light levels got really low, the auto gain control kicked in, but it also got very noisy, so I had to decide to limit the AGC, take underexposed footage and "fix it in post". Now it looks OK on my monitor (ASUS 24" 1920x1080), only a little bit of noise that I can put up with but when played back on the blu-ray player and big screen, it looks ridiculous.
2. some footage from one of the Sony cams is way over-bright - that's something that I can easily correct.
I matched brightnes and colour from the 3 cameras as best I could, and it looks OK in PPro on the program monitor, but looks awful when exported and played via the blu-ray player to the big screen. I put the same disc in the blu-ray drive on my computer and watched the film on my monitor, and it looks OK. I mounted the ISO as a disc, and watched that with VLC, and it looks OK.
I took one section of "noisy" video, approx 60 seconds, and exported it 3 times, playing around with bit rates and noise reduction settings. The uncorrected export was very noisy, and each of the 2 "corrected" versions are improvements, but all of them are very noisy compared to the same footage previewed in PPro.
The export setting "use previews" was unchecked, so presumably it re-rendered everything for the build.
Where should I look to identify the place where the video noise is being added or exacerbated? It's ONLY on the Canon footage, so could it be a codec issue? I started to play with the footage in After Effects, but I haven't had a lot of experience with AE yet.
cheers

Have you calibrated the HD system in your lounge with something like
Amazon.com: Spears & Munsil High-Definition Benchmark Blu-ray Disc Edition [Blu-ray]: Stacey Spears, Don Munsil: Movies & TV
or
Amazon.com: Digital Video Essentials: HD Basics [Blu-ray]: Joe Kane: Movies & TV?
If not, then do that before making any judgments. I personally like the Spears & Munsil disc.

Neato Video Noise Reduction Filter

Merry Xmas
A fellow filmmmaker has used the 'Neato Video Noise' plug in with pretty good success. Was wondering if anyone else out there has tried it?
I have some underexposed footage shot on a DVX100, (low daylight footage), which I tried tweaking with the FCP HSL Filter. But as you may know, the HSL Filter must be used carefully (sparingly), or it will cause grain.
Anyone know if Neato's Noise Reduction Filter works more efficiently?

Thank you

No, there are no built-in noise reduction filters.
There are a number of free and commercial solutions out there ... the free ones are obviously worth checking out but less capable (try TMTS Noise Reduction and Smart Noise Reduction), of the commercial filters http://www.neatvideo.com/ and http://www.revisionfx.com/products/denoise/ seem popular.

Video Noise plugin

Ive "aquired" soem hdv footage that was shot inside with very high GAIN ergo there is lots of grain/video noise.
Im trying the Neat plugin for Pr which seems decent. Anyone have experience with any other noise reduction techniques?
IN DV world i could get away with stacking copys of clips, bluring the top one and applying screen with low opacity. But with hd the grain seems a bit harder to hide.

Hello,
i work often with remove grain filter in After Effects and like it.
But since i work with HD i have noticed several time problem. My problem comes when i downscaling my HD footage to SD with after effects. When i try to apply remove grain filter on my new SD footage (downscale HD with After fx) nothing change. i tried several codec (.avi, .m2v even images sequences) for my downscaling without have change when i apply remove grain filter. When i apply remove grain filter on one image (still picture) of my sequence image i exported that run ! Could someone explain me what the problem ?
We can notice in CS4 that filter "remove grain" disapears in Adobe media encoder. Now the only one filter is gaussian blur.... bad new.
Thanks and sorry for my english.

How do I deal with a lot of video noise in underexposed aeras. This also happens at low ISO

I seem to have a lot of high video noise in underexposed aeras. This is specially visible in the blacks, it shows more because of the blacks and happens at all ISO values. On other forums I read this can be caused by camera been used a lot and or to much ISO. What do you recommend so I can have less noise in the videopicture?

Some users had reported a similar issue in 3.3Beta2, but it was resolved for them in 3.3Beta3, but it seems like that didn't work out for you.
Can you share a small project that reproduces the issue at [email protected] and [email protected], so that we can look at the issue?
Thanks,
Neha

HDMI/DVI video noise when running with 9400M

I have a late 2008 MBP. I connect it to my Sony 52W3000 using Apple's mini DisplayPort to DVI adaptor and a DVI to HDMI cable. When I use the Nvidia 9400M (Better Battery Life in Energy Saver system preference) I get lots of video noise in the form of little red pixels. When I switch to the 9600M (Higher Performance in Energy Saver) the image is beautiful and without noise.
Is this problem inherent with the 9400M? Is it Apple's DisplayPort -> DVI dongle? I would rather conserve battery AND have a decent video image. I'd also like to get a Mac Mini to as an HTPC but don't want the terrible noise I get from the MBP when using the 9400M. I somehow doubt it's an Nvidia problem.

I have a UniBody MacBook (before they were re-branded as PRO), with a GeForce 9400M. I get nasty white noise when using the Mini-DisplayPort to DVI cable, connecting to a Samsung 2333HD monitor via DVI (no HDMI involved here). I put a video on YouTube to document the issue. Quality is not great, but you can clearly see the white pixel noise on a black background. Looks like the sky at night. I'm wondering if this is a case for my AppleCare Protection...

Can't see video in Color

Hello there. I am using an iMac 17" with an ATI Radeon X1600 video card. When I import a video to color from FCP, I can't see any type of preview. I can see the video in the time line, however I can't see any scopes or waveforms. I already thought it was a problem because "Update UI During Playback" wasn't checked, but after I checked that, nothing changed.
Thanks in advance for any help you can provide!

Not sure if this helps, but I had two NVIDAI GeForce 7300s installed. On a hunch, I pulled one out and the video and scopes suddenly appeared.

HP Z400 600W PSU, reduce the noise?

Hello, i bought the 600W psu a few months ago because i wanted to have a great graphic card.
But i think the noise from the computer is way to loud. Im verry sure its the PSU since the 475W version was verry quiet when i tried it.
Can i do anything to reduce the noise from this thing? Open it, replace the fan to a better one perhaps?
I know there are some people who have managed to get a ATX PSU into their HP z400 using a "HP Z400 PSU to standard atx adaptor" but i dont really know how to build a cable like that... Its probably easy but i have no knowledge about things like this.
https://plus.google.com/photos/111388964237560787781/albums/5362166283613539361
If anyone could buid this cable for me and i could buy it i would really appreciate it! Becuase then i could use whatever ATX PSU out there?
