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.

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

(Official support for videos up to 1920 × 1920 pixel. Shorter or split videos decrease the processing time.)
