Noise/grain remove – the best way?

[Angelo Mike]

Getting a new lens can help dramatically. You can probably find good lenses in your area on craigslist for a low price.

Which one would you recommend?
I bought Canon 24-105 because it has stabilization system, really needed while recording. Samyang is quite light (f/1.4) so not bad. Which lens could be better in your oppinion?

P.S. In the attachment I send the print screen from my test video recorded with 5D MK3 and Samyang lens 24mm f/1.4 (ISO 100, 50fps).
Amazing bad noises in the right side of the image:

Why it’s like this? Do you think NeatVideo can help?

Anna, noise just can’t be removed effectively in post-production. This is physics at work.

Trust me on this – as an old, old video guy who cut his teeth on astronomy, for any given sensor, if you are hitting the limits of low-lux performance, your only practical choice to fix it is “bigger glass”.

Fast lenses cost big bucks, because they have huge aperture.

There is a reason that sensitive telescopes are huge.

If your subject is not moving a lot, you can get better performance by going with slower shutter. If your camera allows it, try shooting at 1/30, 1/15, or even 1/8. You will get motion blur, but that might be a pleasing effect. Traffic looks cool when shot at 1/20th sec.

Thanks Stephen!
What do you mean “bigger lenses?
Could you recommend me something to my Canon 5D Mark III?
Or maybe something is wrong with my Canon, because I’ve seen on youtube a lot of videos (with bigger than 1600 ISO) recording by Canon 5D MK3 and it’s still nice without noises as in my 100 ISO 🙁

What lens you should get depends on what you shoot. One that’s become standard and inexpensive is a 50mm 1.8 prime lens. I use that sometimes, especially in low light. But when I’m moving around a lot and don’t have control of my subject I’ll use slower lenses that can zoom, but being slower makes them cheaper. It’s up to you.

Just keep in mind that zooms are generally more expensive and slower (let in less light/higher f stop). f/1.8 lets in a lot of light. Much more and you may not need it and you’ll be paying more. But lenses that only go as low as f/3.5 are going to give you more noise because they don’t open up as much for more light.

Search online for tests with different lenses to see for yourself.

Thanks for reply!
I used my Samyang which is really good lens – 24mm and f/1.4, but even this makes noises… Strange 🙁
