Media

Importing Audio and Video

Go to Assets and select the media type. On the page that appears, you'll see the list of available media files of that kind. Note the category selector at the bottom middle, you can select media category there too. To add a new one, click on the Add button in the bottom right corner. A file selector window will appear.

Instrumental Music

In the file selector window select a music file. It can be in various formats, .ogg, .mp3, .wav, .voc, .mod, .xm, .it etc. (if you have libflac or libopus libraries installed, then those formats are supported as well). When the file selected, click on the Import button.

All music will be converted into .ogg (with stereo or surround 5.1 channels) automatically.

For the music, I recommend to use SoundTracker or MilkyTracker (you can record music with Audacity too). For old school goodies, there's a modernized clone of FastTracker II running on Linux.

Sound Effects

Same as with music files, but they are going to be converted to an .ogg with mono channel (sounds are mixed into the output using a placement effect, so they must be mono).

For the sounds, I recommend to use Audacity.

Speech

Recordings of voice actors are similar to sound effects, will be converted to an .ogg with mono channel. The only difference is, the filename will be suffixed by the ISO language code, for example _en.

Movies

You can always import .ogv Theora videos without any dependency. But if you have ffmpeg installed, then all the other formats (.mp4, .mkv, .mpg, .avi, .flv etc.) supported as well, and they will automatically show up in the editor's file chooser window.

On Linux, use your distro's package manager, for example apt-get install ffmpeg. On Windows, download the latest from ffmpeg.org (probably called ffmpeg-git-essentials something), and from the downloaded archive, extract ffmpeg.exe (and that file only) to C:\Program Files\TirNanoG (or anywhere in your %PATH%).

Do not try to import full-length movies, only short (1 - 2 min) cutscenes. Audio tracks in videos must never contain speech, only instrumental music and sound effects (that's because game translation would be impossible otherwise). The editor (and the player) takes care of mixing the localized speech audio track onto the video.

To create videos, you can use OpenShot or ShotCut. You can also generate videos of animated 3D models and scenes with Blender. All of these tools can export to Theora.

NOTE: You can convert your video in any format into Theora by hand:

$ ffmpeg -i movie.avi -q:v 5 -r 30 -q:a 3 -ar 44100 -ac 2 movie.ogv

BTW, this is what the editor does under the hood.
