> However, there are several important safety and ethical challenges remaining. Imagen Video and its frozen T5-XXL text encoder were trained on problematic data. While our internal testing suggest much of explicit and violent content can be filtered out, there still exists social biases and stereotypes which are challenging to detect and filter. We have decided not to release the Imagen Video model or its source code until these concerns are mitigated.

The concerns cannot be mitigated. The cat's out of the bag. Russia has already used poor quality deep fakes in Ukraine to justify their war. This will only become bigger and bigger of an issue to the point where 'truth' is gone, nothing is trusted, and societies will continue to commit atrocities under false pretense.
