Odd Blurring in Videos

[Brandon2020]

Hello,

I'm using the latest Blue Iris update as well as the latest Code Project AI. When we have a vehicle passing in front of this camera it creates a blurring effect that goes away after the vehicle has passed down further. All my settings are as follows.

Desktop

i7-6700
32GB RAM
250 GB SSD
4TB HDD
GTX 1050 TI

Running 3 cameras all using substreams and recording mainstream when motion is detected.

The camera that is having this issue is my Amcrest IP8M-2779EW-AI 4k. I'm running this camera at 4K 15 FPS. The following settings are default.

What? You are saying that the Video setup of that camera by Default is the pictures you posted? I mean I know that camera is only 100ish in cost but there is no way I believe that the camera came setup in H.264 setup with FPS of 15 and iFrame rate of 15.. So either that is your setup settings or someone made some changes you were not aware of...

That camera even at that price offers H.264H and I would have to guess came out of the box setup with H.265 and maybe someone changed because of issues with Bi normally not playing well with H.265 however I have a couple of 8mp cameras on Bi that are in H265 format..

So if you MUST change to h.264 at least turn on H.264H. Second issue change the Iframes to be 30 with a 15fps setup camera.. If you have a 20fps then it should be 40 for iframes..

to view my pictures full view right click and view in new tab. These are 2 8mp cameras I am running in Bi, If you would like some more detail on iFrames and what they are and what your settings compared to mine besides the bit rate I did change came setup from factory as double the FPS..

Those were the current settings that I had. I have now made it to h265 and turned off WDR to see if that helps. As far as the iframes everyone says it should be as close to 1 as possible so 15 FPS should be 15 iframes

I can't claim that everything posted on any site is perfect when setting up an IP camera. There is a question in that forum, and it might have been you asking why Dahua and Amcrest cameras have double the frame rate, regardless of the FPS setting. Here's the real reason: Dahua and Amcrest cameras are designed to use the best default settings for optimal performance.

Using 15 iFrames:
Less Frequent iFrames: At 15 iFrames, an iFrame appears every second (since the camera records at 15 frames per second, fps).
Lower Bitrate: This results in a lower bitrate and less storage usage since fewer full frames need to be stored.
Potential for Quality Loss: If there are large changes in the scene, the quality might suffer between iFrames because the P-frames and B-frames will need to store more changes.
Less Robustness: If there's a loss of data, the time until the next iFrame is longer, so the video might be corrupted for a longer duration.

Using 30 iFrames:
More Frequent iFrames: At 30 iFrames, an iFrame appears every half second.
Higher Bitrate: This results in a higher bitrate and more storage usage since more full frames need to be stored.
Better Quality: Improved quality, especially in scenes with a lot of movement or changes, because iFrames capture the full image more frequently.
Improved Robustness: If data is lost, the video can recover more quickly because an iFrame is closer in time.

Benefits of Using 30 iFrames Over 15:
Higher Quality: More frequent iFrames can maintain higher video quality, especially in dynamic scenes.
Quicker Recovery: In case of data loss, the video can recover more quickly due to the more frequent iFrames.
Better Compression Efficiency: Frequent iFrames can sometimes improve the efficiency of compression algorithms in handling rapid scene changes.

However, the main trade-off is the increased storage and bandwidth requirements due to the higher number of iFrames. The choice depends on the balance between the need for video quality and the available storage and bandwidth resources.
