Supported Input Formats

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 in alphabetic order

Windows:

Example:
cd video_folder
tar cf ../video.tar *.png

MacOs:

On macOS devices, it may be necessary to add COPYFILE_DISABLE=1 to avoid copying MacOS-specific hidden files.

Example:
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.

Supported Audio Codecs

• AAC
• MP3
