MSU StegoVideo

Unique tool for hiding information in video (VirtualDub filter/standalone executable)

MSU StegoVideo allows hiding any file in a video sequence.
Different popular codecs were analyzed and an algorithm, providing the smallest data loss after compression, was chosen. Convolutional codes with Viterbi decoding are used to correct occurred errors.

You can use MSU StegoVideo as VirtualDub filter or as standalone .exe program, independent from VirtualDub. Click links below for instructions:

The number of errors decreases when you increase redundancy!

This is an example of distortions in video with info.

Quality of information extracted from compressed video depends on codec, data redundancy and frame size. The greater information redundancy, the greater probability of extracting file info without errors.
