Very bad picture quality

Posted by Jonathan Black on March 3, 2019 at 9:47 pm

Hello all,

I have just begun shooting video, I am really enjoying it but I am concerned my 5D MKII maybe unwell.

***MEDIAFIRE link below*

I am using the 24-70 L older type lense and I am getting a lot of noise and strange artefacts when filming.

This example is the worst probably, I am using a Neewer lighting kit, my exposure meter on the camera is centred and my ISO is abiding by the 160,320, 640 idea of less noise. I think the example is ISO 320, fstop 4 or 5.6.
1080p 25fps and 50 shutter speed.

I have been trying all kinds of combinations of ISO, aperture and getting disturbingly poor results.

I cannot get anything remotely sharp or close to nice looking.

If anyone can identify what they are seeing that would be great.

Thanks,

Jonathan

Hi David, yes I thought there maybe an element of that alright.

But after doing a lot more experimenting I realised the lighting in the original clip may not have been enough, I have been practicing focus today in daylight and I’m very happy with the sharpness etc.

The footage is shaky to begin with but the 2nd half is better.

I will put a youtube link up soon.

Cheers,

Jonathan

Here’s the improved footage, It’s far from perfect but for shooting musical performances it’s a good base to start from.

I have it all planned, It is not a concert, but more a performance purely for the video.

The room will have similar light to the video above, no typical stage lighting or audience.

I do indeed, and have access to a couple of good quality ones if needed.

Have you tried experimenting with Magic Lantern RAW? It’s a hack that let’s you shoot RAW with your MKII. Huge dynamic range increase and because it is RAW you can do so much more in post with the footage.
