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:

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?

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 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.

Is there a video noise reduction facility on final cut pro x?

İs there a video noise reduction facility or plugin on final cut pro x?

I appreciate this is an old thread and things have moved on but...
I have just been given a whole load of GoPro footage to work with that is very noisey (video noise) and needs some work.
FCP X still doesn't seem to like 'Neat Video' which works well (at times) but apart from the hang-ups takes a lifetime to render. The 'FxFactory' module isn't really doing it for me... Has anyone tried the 'Pixel Studios' plug in contained in their ProLens offering?
Thanks

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?

Video Noise Reduction

Does anyone know what filter I can use in timelin to replicate this video noise reduction?

OK.
My personal choice would be Dark Energy for After Effects. It's amazing! But it's also pricey at $500
Neat Video also makes a plug-in for noise removal, and while many people swear by it, I found it somewhat...'incompetent' for the task compared to Dark Energy. At least with the couple of clips I tested with.
Red Giant's DeNoiser is also an option, but I have no experience with that one.

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.

Grain Reduction

I'm one of what appears to be thousands of people who have had trouble with grainy video. I know the best solution is to re-shoot, but I don't have time. I've been all over these boards (and others) trying to find the second-best solution. I've read that the 3-way Color Corrector in FCP can help. I've read that plug-ins such as CHV and Nattress are good. And I've read that the Grain Reduction FX in Color can work. My ideal solution is not to spend any money, but not being very proficient with Color yet (and without time to learn before this project needs to be complete), I haven't had a lot of success using it. The CHV demo seems to work the best for me. I want to know what YOU think is the best of the bunch. Is it worth it to spend the money or is it possible to get similar results as CHV using Color or FCP's color corrector?

GRAIN IS ONLY CAUSED REALLY BY FILM. NOT SURE IF YOU ARE USING FILM AND THEN WORKING OFF OF THE FILM TRANSFER TAPE MASTERS. IF YOU ARE USING A VIDEO CAMERA. WELL THEN IT IS REALLY NOISE NOT GRAIN THAT YOU MIGHT BE SEEING. YES I UNDERSTAND THAT YOU DON'T WANT TO SPEND THE MONEY ON PLUGGINS. SPECIALLY WHEN YOU MIGHT USE THEM JUST FOR GRAIN/NOISE REDUCTION. THE ONES YOU MENTIONED ARE GOOD. THEY ARE REALLY JUST SOFTENING THE IMAGE. IN FCP YOU SHOULD TRY THE GRAIN OR NOISE REDUCTION FILTER. YOU WON'T BELIEVE HOW POWERFUL THEY MIGHT BE. AND JUST FOR THE LITTLE REDUCTION YOU MIGHT BE WANTING. ITS FREE ITS ON YOUR SYSTEM ALREADY AND COULD PROBABLY MAKE A HUGH DIFFERENCE. NEXT TIME JUST REALLY TAKE THE TIME TO SET UP THE EXPOSURES. IT REALLY COMES DOWN TO HOW THE ORIGINAL CAMERA MASTERS ARE EXPOSED. GIVE IT A SHOOT AND CREATE GREAT MATERIAL

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.

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!

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...

Premiere Pro CS6 - video noise in the exported file

Hi everyone,
Im trying to make the transition from FCP7 to Premiere Pro CS6. I edited my first project with Premiere Pro and exported the sequence. However I noticed that the exported file had more video noise than the original clips.
The material is shot by Canon 5D Mark III and edited natively in the Premiere's timeline. Then they are exported to ProRes 422. After noticing the noise I exported the sequence as "match the sequence settings" and it created the .mpeg file. Same thing, there was noise. I then tried another other formats of that same clip and transcoded the Mark III footage to Xdcam EX 1080p before sending to premiere. Same thing, no matter what I did.
The only way i got the exported file to look the same as original file, was to convert the files before sending to ProRes 422, then edit those files in Premiere in the sequence thats settings are XDCAM EX 1080p and then to export it to ProRes422.
Do you have any thoughts for this. The noise I'm talking about is not a huge amount of noise but definitely noticeable if you look the FULL-HD material.
I really hope there is some setting I missed. Im using Mac pro 2009 and Macbook pro 2011.
Thanks

Hi Thomas
Try exporting by enabling "Render at maximum depth" and " Use maximum render quality" in the export dialogue window.

Imported animations from SolidWorks have video noise at top

New problem with my proof-of-concept video at work...we are intercutting short animation sequences with "live" video clips to create a sort of "how-to" video for employees. The animation sequences are rendered in SolidWorks Composer as *.AVI files, and then imported into Premiere Elements 12 (all of which is done on a Win7 machine). The entire sequence is then published from Premiere.
The problem is there is a thin line of "video noise" across the top of the animation sequences. It doesn't interfere with the content of the video, but it's annoying as heck, and we can't figure out what's causing it. We've tried:
Changing aspect ratio on animation export (from within SWC) to match the size of "live" video clips in Premiere project.
Changing aspect ratio on animation export (from within SWC) to match final published video size of Premiere project (i.e. 720x480 30fps 4:3).
Turning off display of background "paper" from within SWC.
Running auto-analyze on imported animation clips within Premiere.
Exporting from Premiere in several different formats (i.e. *.wmv, *.mpg, etc.).
Exporting the animation sequence as a series of high-res images (from SWC) at 30fps, importing images in Photoshop and rendering as Quicktime video at 30fps.
None of these has solved the problem. Interestingly, we have yet to find an export setting in SWC that causes the animation sequences to be the same size as the Premiere video. Neither setting the aspect ratio to 1920x1080 (the size of the "live" video clips in the project) nor setting the ration to 720x480 (the Premiere-exported size of the video) causes the animations to be the same size as the video on either side of it.
Anybody have any ideas here?

CanrigTW
Great news. Thanks for the follow up. Good job.
Did you ever say what computer operating system your Premiere Elements 12 is running on?
Were you in the Expert workspace when you were seeking the Crop Effect?
And then when you edit the Crop Effect
Just in case screenshots.
But, the Scale worked great for you.
Best wishes
