How to make .VP6 videos:

Download and install the necessary files:
VP6 codec
Any Video Converter
Xvid
Video editor of your choice

Conversion to .AVI:

Go to your video editor (I use DaVinci Resolve)
Open the video you want to convert to .VP6
Make sure to shorten it the same as the length of the .VP6 video you're going to replace

Resize the video to 1280 x 720 (1920 x 1080 will not work)

Export/Save as .MP4

Open Any Video Converter

Click "Add or Drag File(s)" and select the exported/saved .MP4 file

Select "Customized AVI Movie .avi"

Choose video codec "xvid", then frame rate to 30

Choose "convert now!"

Conversion to .VP6:

Open VirtualDub
Drag and drop the converted .AVI video

Select "Video>Full processing mode"

Select "Audio>Full processing mode" and "Audio>No audio" (this depends on whether the game uses audio from another file or not)

Press CTRL+P
Choose "VP60R Simple Profile"
Save as .AVI

Open "VP6 Converter 008"

On the "Input video file", choose the directory of your .VP6 video
On the "Output video file", choose the directory of where you save your .VP6 video
Select "GO!" to convert

Rename the file to the .VP6 you want to replace and you're all done





Notes:

After installing the VP6 codec, you can open VP6 files with VLC media player.

Never use vp6 enconder with files with name with spaces, it will give you error of sound not found.
