What is your video bitrate setting? Show that screen
also for faster objects, “auto” may not be a fast enough shutter speed. Try a manual exposure of say 1/1000 for example, or a range 0-4. I think "Auto" is allowing the camera to adjust gain and other settings to compensate for the scene change. In this case, it senses a change in light as the truck passes blocking some of the light
Also during daylight, 3DNR is too high. Try 25

Cool.
6144 should be enough not knowing the camera model. I like to run mine high. 8192 for 2MP and 10-12MB for 4MP cams but plenty of folks run 4-6MB

I’d play with exposure and DNR and see which is having the most affect.

I have a budget model - IPC 2431T, so I don't have the same settings, this what I have now:

I do have similar experience with cars going in and out of heavy shadow areas. Especially with a 2MP camera with a smaller sensor and your 2431 has a similar sensor
If that doesnt help, may try playing with 2x or greater Iframe. While not what we all preach, it can have a positive effect.

My current bitrate is maxed.
Will try these settings.
BTW, this happens even when there are no shadows at all (on the noon 11:20 AM, no clouds).
After the Iframe change, view the main stream using VLC started to be choopy (using cable connection).
Also, the recorded video has missing parts, I mean, I see a car appearing in the middle of the street.
Reverted the Iframe settings,I will stop tuning this, not worth the effort, probably this is what this IPC is capable of.

There is a good thread here on IPCAMTALK that I use that helps me understand cam exposers. I have it booked marked.

Common issues with camera image
Here is a quick guide to what might go wrong with the image of your cctv camera, and how to fix this. MOTION BLUR: This is probably the most common issue, new camera owners run into. Many times on this forum I've seen posts like: "I bought a set of cameras recently. The image looks great on...

If that cam has it, try H264B or H264H instead.
Disable the tripwires and see if that helps, sometimes more than two IVS rules overwhelms the cameras cpu.
Do you see this same problem in the cameras direct live view or only in Blue Iris?
As an aside, turn off the Audio Noise filter, and the audio will improve.
