Convert MKV to BNK

Understanding MKV and BNK file formats

MKV (Matroska Video) is a popular multimedia container format that can hold video, audio, subtitles, and metadata in a single file. It is widely used for storing movies, TV shows, and other video content due to its flexibility and support for multiple streams.

BNK files are typically associated with Wwise SoundBank files, used in video game development. These files contain audio data, sound cues, and instructions for game engines to play sounds at specific times or events. BNK files are not standard multimedia containers and are specifically designed for use with the Wwise audio engine.

Can you convert MKV to BNK?

Direct conversion from MKV to BNK is not straightforward because these formats serve entirely different purposes. MKV is a video container, while BNK is a proprietary audio bank format for games. However, if your goal is to extract audio from an MKV file and then package it into a BNK file for use in a game, you can follow a two-step process:

1. Extract audio from the MKV file (usually to WAV or OGG format).
2. Import the extracted audio into Wwise and generate a BNK file.

Step 1: Extract audio from MKV

Use a tool like MKVToolNix or FFmpeg to extract the audio track:

• MKVToolNix: Open the MKV file, deselect video and subtitle tracks, and export only the audio.
• FFmpeg: Use the command: ffmpeg -i input.mkv -vn -acodec copy output_audio.ext (replace ext with the desired audio format, e.g., wav or ogg).

Step 2: Create a BNK file using Wwise

Once you have the audio file, use Wwise (by Audiokinetic) to create a BNK file:

1. Open Wwise and create a new project.
2. Import the extracted audio file into the project.
3. Configure the sound properties as needed.
4. Go to SoundBank Manager and add your audio to a new SoundBank.
5. Click Generate Selected to create the BNK file.

Recommended software for MKV to BNK conversion

• MKVToolNix (for audio extraction from MKV)
• FFmpeg (for audio extraction and conversion)
• Wwise (for creating BNK files from audio)

Summary

While there is no direct MKV to BNK converter, you can extract audio from MKV files and use Wwise to package it into a BNK file for use in game development. This process requires both audio extraction and sound bank creation tools.
