| Wintermute supports the use of Ogg Theora video files, which are very well compressed without losing much quality. The problem I had was that none of the methods outlined anywhere I could find for converting an AVI/MOV file to Ogg Theora was actually working on a level I'd call "professional" - very frustrating. | Wintermute supports the use of Ogg Theora video files, which are very well compressed without losing much quality.

| So, I've taken it upon myself to make this small guide Roll Eyes. This is the method I use to get Theora files into the engine that are small (a 2-min video file is 3MB-8MB, depending on resolution) and that work, as a big plus, with optional subtitles. | So, I've taken it upon myself to make this small guide Roll Eyes.

| 6) "ffmpeg2theora.exe" is a drag-and-drop utility, so drag you're Uncompressed, Resized AVI file onto the icon and wait for it to convert. It will automatically save a .OGG file in the same directory as the original. The .OGG file will be very small by comparison; for a test run, I used a 100MB file...it is now 300kb with no noticeable visual or audio loss. Nice! | 6) "ffmpeg2theora.exe" is a drag-and-drop utility, so drag you're Uncompressed, Resized AVI file onto the icon and wait for it to convert.

| Cool Basically, the "Compendium" window shows the entire sequence. When you play the movie, there is a box at the bottom of the main window marked "Actual Frame:" - this shows the frame the video is on at any given point. You put the "Actual Frame" values into the "From" and "To" text boxes. For example, if a person in the movie starts saying "Hello" at frame 34 and ends at frame 45, you'd put 34 and 45 in the "From" and "To" boxes respectively, and then "Hello" into the subtitle box. There are a lot of buttons, but the ones that you'll use a lot are the ones with two rectangles in them in the main window; these insert a new subtitle. After you've inserted a few of subtitles, you can play back the movie and the subtitle will light up when it will show up during the movie, so you can be sure it works. | Cool Basically, the "Compendium" window shows the entire sequence.

| And you are done! Play the ogg file in game, watch the subtitles show up on cue (unless you have them turned off) and pat yourself on the back. Since the subtitles are a separate file and not part of the movie, they can be turned off and also translated into different languages for localization. Sure, you might get away with just using ffmpeg2theora on everything, but chances are you'll get garbage, it won't be the right size, the audio won't work, or everything will be out of sync. This method ensures that the converted file IS the original taking up less space. | And you are done!
