I have been playing around with .bik files to incluude them in a new map i am making. The files do have sound in them but when i play them the sound is missing. I did make an ambient_generic and paused the start to sync with the .bik file, i got it working great, but the draw back with this method, is that i am doubling up the file size. Is there a way to get the sound playing through the .bik file.

Which method are you using to play the movie? If you are using a vgui_movie_display it will only play the image, however if you are using a logic_playmovie it will play the sound and the movie (a cut scene of sorts).

I am trying to put the footage onto a screen, so i am using the vgui_movie_display, looks like i will have to use an ambient generic and sync it with my footage. I tried the logic_playmovie, this is good to know, as i can make an end sequence, thanks.

If it is possible to compress the .bik by removing the sound, do so. After all, videos are just a series of images with sound.

I tried to remove the sound when changing to a bik file but there was no option for that. I then had a look at virtualdub which i use to compress .avi files, it has the option to delete the sound, so thats what i will do, cheers again.
