Powershot SX170, too much noise

[musicus]

I am getting a continual problem on my videos. Too much noise. 

This can be seen here:

'Noise" might not be the most accurate word - but what I mean

is the "activity" that is ever-present. I see this even when I use

spotlight on other vids. I am mostly concerned with indoor videos

with moderate lighting. Any ideas on aperture, ISO settings, HD, etc?

Thanks.

In terms of what I personally see in the videos...  I see noise, but also a decent amount of compression artifacts.   YouTube is definitely making things worse since you have a second-generation video.  The vast majority of video compression is lossy.  Meaning that everytime it is transfered to another system and re-saved, more information is lost leading to lower quality.

Consumer video equipment, as I mentioned earlier, end up using so many compromises in order to reduce heat and reduce file sizes when capturing video.   Most have smaller sensors as well, which even in outdoor shots, don't produce as clean of an image as when using equipment with larger sensors (specifically the size of individual photo sites).

Only you can be the judge of it the footage is good enough for your purposes.   Personally, I don't see anything really wrong with them.

Also note that if wanting ultimate quality, that can come in at a massive cost.  I was recently toying with the idea of getting the Canon EOS C70.  A massive step up in terms of video quality over my Vixia HF G50, but also around 10 times the price for a single-lens setup.

Thanks, I appreciate that.
