Convert OGG to BNK

Converting Ogg Vorbis Audio Files directly to Bink Video Files (.ogg to .bnk conversion) should be possible and typically relates to users attempting to import an audio track (OGG) to a BNK video.

It appears that your options are limited. A reliable alternative would be using Freemake Video Converter, which allows users to import OGG audio and re-save it in BNK video format (black screen with an audio track).
