Very noisy Video quality

Mitch345 — Wed, 14 Dec 2016 22:56:31 GMT

Hey all! So Ive recently started making videos on a regular basis and ive noticed a very very strong grain in my videos. Ive search basically everything up and I just cant seem to figure anything out.

This is the video I took just as an example of this horribel noise that is happening. I've tried it with higher light aswell and it just doesnt seem to fix it. If anyone has an help or suggestions that would be great!

Higher light level may still not be enough light to get to a low enough ISO. What does the metadata say about camera settings.

Where can I find the Metadata?

Use ISO 160, 320, 640 and ISO 1250. It will give you less dynamic range but also less noise when you video record.

My camera only has ISO 100, 200, 400, 800 etc. It gets unbeliveably dark when I turn it down to 320 and I am using professional lighting. Its on F/4 and I am completely stuck

"Professional lighting" doesn't define intensity. Sounds like there's just not enough light. What settings does your camera want to set if you try to take a still photo in P mode?

The lights are as bright as outside if that puts it into perspective. And in P, its 40, 4.0 and 400 for the main settings. That is with the lights on. I dont have the noise issue when It comes to photography but videography is a different story

If you're recording at 60 FPS, then 1/40 sec shutter speed isn't fast enough. You would need a faster shutter, which means a higher ISO setting ... and more noise.

Recording at 1920x1080 at 30 fps. I set the shutter speed to double which is 1/60. Those were just the settings that the camera came up with while in automatic.

An EOS camera with video recording without ISO 160?

Re: Very noisy Video quality

Mitch345 — Fri, 16 Dec 2016 01:24:30 GMT

These are the only options I have for IOS.... 100, 200, 400, 800, 1600, 3200, 6400

The manual is your friend.

My bad. I searched and found this out:

"I think there may be a bit of confusion here. Entry level Canons like the t3i (600D) don't allow you to set ISO values such as 160 or 320 but the camera can set values like this when in Auto ISO mode - until recently I used a 600D and can confirm shots from last weekend with ISO values of that range."

And, what are the recording like when you use the "automatic" settings?

If you increased the shutter speed to 1/60, compared to 1/40 in the automatic setting, then you will also need to increase the ISO to maintain the same exposure, which increases noise.

BTW, the keyboard video is recorded in a fairly dark environment.

Yes that is very true it was quite dark. When I use manual, again, it has that super grainy look to it cause it turns the ISO way up even in decent light.

Welcome to photography and videography.

You have encountered what setting an exposure is REALLY all about. You cannot have it all at once. In order to gain something, then you have to give up something. It is all about the Exposure Triangle: Shutter Speed, Aperture, and ISO.
