Data Requirements
Our software is optimized for the following data specifications.
Faces
- Size: Faces need to have an area of at least 200 pixels (e.g. 10x20 pixels) for both DNAT and Speed-optimized Blur. Precision Blur is exempt from these limitations.
License Plates
- Size: License plates need to have an area of at least 100 pixels (e.g. 20x5 pixels) for both DNAT and Speed-optimized Blur. Precision Blur is exempt from these limitations.
- Supported countries: Optimized for license plates from Europe, China, Japan and US. Other regions are available upon request.

File Size
Our online API only supports file uploads smaller than 2GB. This does not affect on premise installations.
Shorter or split videos decrease the processing time.
Archive
Please use tar only for video files without subfolders, with all frames belonging to the video in the top-level directory, in order of video. Frames inside the archives are processed alphabetically.
E.g.
cd video_folder
tar cf ../video.tar *.png
On macOS devices, it may be necessary to add COPYFILE_DISABLE=1
E.g.
COPYFILE_DISABLE=1 tar cf ../video.tar *.png
Resolution
Official support for videos up to 1920 × 1920 pixel.
Images/videos larger than 1920x1920 pixel are downscaled for detection and redaction. Redacted areas are rescaled and inserted into original file.
