Camera - selection and parameters

To ensure maximum measurement accuracy and the correct operation of AI algorithms, submitted video recordings must meet the following requirements.

---

📹 Technical Recording Parameters

Parameter	Minimum	Recommended
Resolution	640×480 px	HD 1280×720 (1 MPix) or higher
Frame rate	15 FPS	Higher = smoother object tracking
Video length	90 seconds	—

Supported Formats

• Recording format: AVI, MP4, DAV, FLV, WMV, TC, H265 (or other standard video formats)

• Encoding: Basic AVI, MPEG, MP4 encodings, and H264/H265 encodings, including variable frame rate (VFR)

We support a wide range of video formats and encodings and are constantly expanding our capabilities.

⚠️ Important Notes

AITracker Warning: For videos with variable frame rate, the seek() function (jumping in video) in the AITracker GUI program does not work correctly!

Note: We do not support interlaced videos, where even/odd scan lines are recorded alternately. Wikipedia

📁 Video File Naming

To allow the AITracker system to automatically recognize the date and time of the recording, the video file name must contain this information. This information is essential for correctly assigning measurements to a specific time period.

🔎 How Does It Work?

The system does not read the time from the video image (e.g., a clock displayed in the corner of the film). The only source of time information is the file name and the frame number. This means that correct file naming is crucial.

📅 What Should the File Name Contain?

• The date and time of the start of the recording

✅ Supported File Name Formats

We support many popular formats found in industrial cameras and monitoring systems. Here are some examples:

Example File Name
12.05.00-12.10.00[R][0@0][0]
02-OMAZ_2021-05-06_2355_0000
R51_ch1_Main_20210408100000_20210408110000(1)
063732_100_044419723_0300.h264
SCPR_12002_BOCHNIA_cam2_20231213001158_20231213001751_97842

Note: The system defines the time on the recording solely by the name and frame number! We do not have the option to read the clock image embedded within the video frame!
