How To Avoid Noise In Your Video - My Most Asked Question Answered

[@HarvVideoAudioStuff]

Enjoy all, please add your tips for avoiding noise below so it becomes a treasure trove of knowledge! :)

[@thokeJackass]

This is actually almost the opposite BUT I see a lot of aspiring cinematographers shooting at the lowest f/stop possible to make sure to get as little noise as possible BUT they don't consider, that they will be moving around all the time with a depth of field that is so small that their subject's eyes is almost never in focus - that means you won't have a sharp image for most of the time and then what good does the noise reduction do? TL:DR - Focus/sharpness is more important than avoiding noise - at least in my opinion.

[@SBBLURAY1]

Missed your videos. More content, please. I know it is not easy.

[@HarvVideoAudioStuff]

Many thanks, I’ve got loads in the pipeline :)

[@SeanBrown23]

You're using a mirrorless camera? No offense; but there's still a bit of noise in the video. One the problems I find with mirrorless cameras is the noise from their high ISO. Full body cameras are preferred in this situation because they allow one to lower the ISO to 200, and almost completely eliminate noise.The only thing that would need to be improved upon would be the lighting and pulling focus.

[@HolyChristianFellowship]

Thanx a Lot

[@christianhotter]

All good tips. I know you mention not wanting to tell people to get lights, but as an event shooter, they cost less than upgrading a camera or lens and can be rather essential for some shots. Small light panels can be pretty cheap (even ones with remote controls and phone apps). Toss one (or two since you have a remote to turn them on) on a light stand or hold it in your hand (above the subjects eye level) when you find yourself in a situation where the room is too dark to get a good shot. I went with a couple cheapo lights from Yongnuo that have worked well for the last few years.

Harv, I like the way you tell us what you are going to cover in the video in just the first few seconds.

[@HarvVideoAudioStuff]

Thanks Jacob 😉

I reached most of these same conclusions about noise, but was curious if other people felt the same way, so thanks for making this video! I pretty much do exactly the same except I prefer false color to waveforms. Thanks brother, just subscribed!

Great recommendation re prefering a higher ISO over cranking up light in post. The technical reason behind is quite simple, but nobody talks about it: The absolute level of the noise floor from the sensor is always (nearly) the same, but far below visibility in the lights. So, when cranking up the shadows in post, the noise floor gets amplified, too - that's where the ugly noise in the shadows comes from. Regarding your general recommendation regarding "always overexpose Log-footage" I would not fully agree with. Here my thoughts, backed from some experience: Indeed, Log profiles add a bit more headroom towards the lights (lets say up to 2 stops) - but this comes from how the camera SW encodes the sensor readout, assuming the sensor provides the exposure headroom in the lights. Good sensors tend to offer more dynamic headroom than linear readout and processing of the readoud in the camera (limitation of 8 or even 10 bits). That's why encoding the sensor readout with a Log-curve adds some headroom in the lights. But once you overexposed the sensor in the highlights it does not matter which picture profile you are in - the highlights are flat white, and no Log-curve will help any longer. So, my recommendation from some poor experience with just overexposing by 2 Stops in Log is - and, here we're getting in sync again: - Prefer higher ISO, especially when the camera has dual ISO - Watch the highlights, e.g. with false colors, histogram, wave form monitor, zebras. - If you need to expose for some 42 IRE (e.g. for getting a face exposed correctly), then give up the highlights A common mistake when using Log-profile on the camera is to set the HDMI output that goes into the monitor at a Rec709 conversion LUT and forcing the monitor to analyse the Rec709 HDMI output with its built-in exposure tools - this automatically leads to overexposed shots with the highlights gone. Instead, you need to set the HDMI output to native (here Log) and select the Rec709 conversion in the monitor. Another great help is to crank camera exposure up and watch the histogram, zebra, or waveform monitor and watch out when it start clipping. For example, my S1H clips slightly above 90%, and not at 100%. Hopes this helps to get clean and nicely exposed footage.

Excellent expansion to a very useful video. Thank you!

[@maoraharon21]

this is a great video I learned more than just avoiding noise. thank you!

Your channel content is absolutely amazing!!! Never got to comment because I mostly watch on Tv! I picked up my phone just to comment! Keep it up🙏🏾

Means a lot to me, many thanks 😄

[@VentusMedia]

Pretty much knew all this but still enjoyed watching you confirm it 😬

[@waophotographyfilms924]

But I wanna more about the relation of noise and iso because when I increase the iso , my footage get noise

[@kenshiromilesvt.7037]

ISO is the sensor sensitivity and there’s a lot of interference in light. So when you increase the sensitivity you increase the interference because everything is amplified

[@Scorpion_007]

Reduce you ISO and increase your room light as much as you can.

[@Scorpion_007]

A Bonus tip... Use dimmable LED lights for long-term ease and smooth experience. Else you will end up moving lights around your studio. Trust me this experience is not good. If you don't have the money wait for some time but invest in something which will add value not pain in your workflows.

[@andrescolintv]

Excellent video. Thanks mate

[@TyroneLT]

About Battlestar Galactica which I agree is an awesome show. One of the best sci-fi shows of all time! I've always wondered if the noise in the image on that show has been left on purpose to reflect the "gritty" nature of the show. Especially the scenes on the hangar deck.

[@KaanSenel]

This is a very interesting video and will definitely help me with my future videos on my channel because I had some issues with noise in the shadows!

[@BlueGuise9]

You think that's noise? You've never seen noise! XD

[@raprein3]

2:52 What is meant exactly by overexposing? Meaning that you higher the ISO or that you have more stronger lights on set?

[@fabianweiss2259]

You can't always just add stronger light to your scenes, but if you can, yeah. The most common technique would either be to up your ISO or to open the aperture

[@whabmedia9288]

Thanks man for review

[@andreaeverywhere7693]

I understand clearly what should i do now... but whatt happen if i using auto iso ?

[@HarvVideoAudioStuff]

I would advise not using auto anything!

[@Alyy4]

Is there a way to decrease noise in a already made video Through an app ?

[@HarvVideoAudioStuff]

A noise reduction app on a phone? Not that I know of as it takes some pretty heavy duty processing. Neat video is brilliant noise reduction software but it’s a plugin for editing software only

[@Alyy4]

@@HarvVideoAudioStuff on pc ? What’s the program name?

[@powpaow]

I've already filmed my clips and it's grainy/noisy all over the picture because we were in a bad lit area. Also I don't understand how ISO works or how to change. Can I fix the noice in a editing program? how?

[@HarvVideoAudioStuff]

Sounds like you need neat video, it’s linked in the description of this video and can work wonders 👍🏻

[@97media71]

So my question is, I have done some filming of like graduation events at night outside in a well lighted stadium but I notice the night sky has a lot of noise in it, is there any tip on how i can correct this? The rest of the video content looks great, and no ones really noticed except me because i know its there. I have a Cannon 80D

[@HarvVideoAudioStuff]

Hmm is there a blue hue to the sky? I ask because blue tends to be the noisiest colour in video. You could pretty easily sort this with subtle/targeted use of neat video 👍🏻

[@Always_help_when_you_can]

Thanks so much for the great video, I'm now struggling on which prime lens to buy for my Sony Alfa 7 iii, I don't have any, I also want to use it on my new RSC2 DJI, I have only one lens which is 24-70 Sony Zeiss, I got all recommendations but not sure which will be the best for me, Sony FE 24mm f/1.4 GM or maybe Sony FE 20mm f/1.8 G, I'm also not sure of the series of the lenses, which means what, would love to hear what you can recommend me. I do now mostly video and very diverse, it can be nature, landscape, flowers, people etc... Thanks so much for any help. Tal.

[@HarvVideoAudioStuff]

Honestly I can’t recommend any Sony lens, whilst they’re good I just find the value to to be pretty poor. Instead I’d go for the sigma art series, amazing quality and far better value 👍🏻

[@Always_help_when_you_can]

@@HarvVideoAudioStuff Thanks so much for this, I'm going to learn more about these lenses, when I go to the photography store, they are talking about that if I'm not using Sony/Zeiss lenses with Sony camera, focus will be slower and function less good, is that true?

[@HarvVideoAudioStuff]

This might be a concern if you were a sports photographer but for anything else they’ll work brilliantly, especially video. Best thing is to try them for yourself 👍🏻

[@guardian_alfred]

Great video ;) Thanks !

[@HikingWithCooper]

Do you have any suggestions as to what could be causing EXTREME noise during a properly-lit shoot? I shot a conference at f2.8, native ISO 3200 (bmpcc 6k) and the presenters were green on the false colors. But they were incredibly noisy. Then the black drapes (less surprisingly) behind them were just lit up with noise. It did this both in braw and ProRes. Converting to 709 seemed to help some but I still had to apply NR to the point where the faces became blobs to make the footage usable. Again, the faces were properly exposed. Ideas?

[@HarvVideoAudioStuff]

Hmm this does sound unusual, has this happened since or was it just on this occasion? Have you run some test shots to see if it’s a fault with the camera? I’ve heard of sensors failing before and high noise being one of the signs, however this was on earlier Sony alpha cameras. Was the event well lit?

[@HikingWithCooper]

@@HarvVideoAudioStuff Hi, thanks for replying. It wasn't lit how I'd want it to be but histogram and waveform were fine. A bit to the left but not crushed. Plus the green areas from false colors still had tons of noise. This was on ProRes. I had a similar issue recently with braw, granted the lighting was less sufficient there but was still brighter than any night shots I would want to get.

[@TheCuteMinna]

Help pls 😢 🙏.. i have my canon eos 750D, whenever i shoot in good light but it has noise on my background, also whenever there is grey and black colors near or back. What should i do! My lense is typical 18-55 mm.. what shoud i do?

[@WOWmaticFilms]

Buy Canon 50mm 1.8 prime lense and mostly ur issue wl b solved

[@hubsoftecommerce]

some people say keep iso lower and some say higher ,what shoud i do

[@HarvVideoAudioStuff]

It’s hard to answer not knowing your setup or situation but by just following the steps in this video, not starving your sensor of light and exposing correctly you should be in good shape 👍🏻

[@thewurldz]

So u can't record video without noise right?
