Input on dialing in another camera

[TheE]

For the life of me, I can't figure out this scene - I figured the lighting would be perfect.

Our goal for this scene:

1. When the video is stopped, be able to read the bags better at the red line in the image below.
2. Figure out why the gentleman looks pixelated when the video is stopped (example at the 6 or 7 second mark).
3. Figure out why there is a color streak in the video.
4. Brighten up the scene a tad.

Red line image mentioned above:

Also, if it helps, here's the large LED light off the red line:

Are you running any backlight setting? It kinda looks like WDR or SSA is on?

I think your troubles , say vs a front of a house, is that the light is straight up 20ft in the air. You dont get as much light on faces as you would with say a porch light at just above head level.

Also FWIW in that environment with facial detail and reading letters on bags I would recommend a good 4K camera. But mostly I think its a lighting issue

Might try reducing DNR to about 35 and see how it does also, may be the source of that red streak... that or backlighting

Zoom in more if you can. Try increasing bitrate to 12,288, up FPS to 20 or 25, up shutter speed a little more as you can given the light, gain down to 50, sharpening down to 25-ish. Along with reducing DNR, that should be about as good as it gets (at the expense of using more resources). Maybe play with brightness/contrast some from there to get it a little better.

Can you work with snapshots? That might be a better image.

Good morning and thank y'all for your input!

Backlight is off.




Also, here are two other settings that are still at default, which is Auto:

Zoom in more if you can. Try increasing bitrate to 12,288, up FPS to 20 or 25, up shutter speed a little more as you can given the light, gain down to 50, sharpening down to 25-ish.

Thank you, I will try these settings today.

DNR probably the key.

DNR probably the key.

When you speak of DNR, is this the setting you are talking about?

 

[wittaj]

Those two numbers - you want them as low as they can go before the image is too noisy/pixelated.

The higher the number, the "smoother" or "cleaner" the image, but the higher number contributes to motion blur.

Try 25 for both and see what the image looks like.

^^^^
This and same goes for shutter. Faster is better until image becomes too dark/noisy

Those two things effect how we can freeze and image as crisply as possible. They both produce too much noise as you lower the number at some point. Fine line, so start low as @wittag suggests and increase in small steps to get desired balance.
Try same on shutter, maybe 0-1 or 0-2, you can use decimals as well, like 0-2.3

Also should have said add more light if you can. That's really the best answer Will make it much easier to get there.

 

[bigredfish]

That’s where I started

 

[TheE]

Updated video with the following changes:

• increased zoom
• increased Bit Rate and I Frame

The video still seems pixelated and has color streaking.... I didn't want too much at one time, so now I work with the shutter, DNR, etc.

Updated camera settings for the video above:

 

[bigredfish]

Light +
Shutter Faster
DNR Less

These are the keys. Light makes everything else childs play. It's always ALL about light. Every camera Every scene Everywhere

 

[TheE]

I believe I'm making a little progress — thank you all for your time and help.

Until I can add more light, I made the following changes:

• moved the camera to the left to hopefully pick up more light coming through a small warehouse door.
• updated the below settings in the camera. I still may work on dropping the DNR more.

Two videos:

I think it looks good enough to identify what you want?

 

[bigredfish]

Agree. Not bad at all really.

If greater detail is needed though you may need to go up to a 4K cam

Why do the colors look so patchy and comicbookish?

Why do the colors look so patchy and comicbookish?

Maybe the setting for Sharpness and Saturation is too high for us, but his goal was to to read the bags better.

 

[bigredfish]

That’s why I suspected WDR or SSA but he shows backlight off…

He's got a tough lighting scene..
Here's an example 5442 turret of mine that sits under a dark carport and is a real challenge when sunny (we're overcast today) that I use SSA on because without it .... well see for yourself

With SSA

Without
