Adding
If you like to add a Startup Video, in titles that use Bink video, you need "RAD Video Tools" from Bink Tools and a MP4 or AVI movie.

- 1. Open your mod folder, example: hl2 for Half-Life 2, tf for Team Fortress 2.
- 2. Go to media (if already exist) or create a folder with the name media.
- 3. open startupvids.txt or create a text document named startupvids.txt, then add the following content below:

- 4. Finally, go to the Game directory and place the YourFileName.bik (or YourFileName.webm) video file.
Now the Startup Video has been added.


Regardless, games using AVI format uses .avi file extension, .bik for Bink, and .webm for WebM.

Remove
