Where do I get Video, Audio, and Frame files?
This is a frequently asked question. Find the answer in the FAQ.
Daphne uses mpeg2 (or mpeg1) video files in conjunction with Ogg Vorbis audio files. Frame files are files that map the video/audio files to laserdisc frame numbers.
Creating Video/Audio Files
- A laserdisc from a laserdisc arcade game
- A laserdisc player
- A video capture card such as the ATI TV Wonder 650
- About 30 gigs of free hard drive space
- Windows (video editing on other platforms is possible but beyond the

If you know how to do video editing, and wish to do some editing, now is the time. Video editing is not necessary, so these instructions won't discuss it any further. However, once you've successfully gotten Daphne working with your own laserdisc capture, you may want to learn some video editing tricks to improve the image quality of your video.

Make the Video File
You most likely will need to resize your video to a different resolution than the 720x480 that you captured it in. We won't actually do this yet. For now, you should take note of the resolution that your video will need to be in
|Dragon's Lair||* see below|
|Dragon's Lair 2||* see below|
|Space Ace||* see below|
|Super Don Quixote||512x480|
|Thayer's Quest||* see below|
|Us vs Them||512x480|
Items marked with a * can be in any resolution, but performance will be best if they are in the same resolution that you run DAPHNE in (usually 640x480). You have been warned!
You are now ready to create the final .m2v file. An easy way to do this by using tmpgenc . Tmpgenc has many options, most of which you don't need to worry about. The two things you must do are:
- Set the proper output size for your game (using the above chart, click on Setting in tmpgenc and go to the Video tab)
- Set the Stream Type to be ES (Video Only), not to be confused with System (Video Only)
You can experiment with the other options to see which ones you like. When you are satisfied with your configuration, click the big Start button and kick back and relax. This can take a while.
|About cartoon-based laserdisc games : Most cartoon games will look better if they are converted from 29.97 fps to their original 23.976 fps (namely Dragon's Lair and Space Ace). This is known as performing an 'inverse telecine' on the video. Since this is not required, we won't say anymore about it here.|
Make the Audio File
Daphne uses the Ogg Vorbis codec for audio. The first step is to extract the uncompressed .WAV audio file from your .AVI. Virtualdub  handles this task quite nicely. From within Virtualdub, just open your AVI, then go to File->Save As WAV.
You will need to convert this .WAV file to Ogg Vorbis format. Make sure the audio is stereo, 16-bit, and 44.1 kHz. If your audio stream is at 48 KHz, for example, you'll need to use a tool like Sound Forge to resample down to 44.1 kHZ. If you don't know what format your .WAV file is in, a simple audio editing program should be able to provide that information for you.
Once you've ensured that your .WAV file is in the proper format (44.1 kHz, 16-bit, stereo), you can use an ogg encoder  to convert the .WAV file to an .OGG file. Sound Forge can also save directly to .OGG for those of you so inclined.
Put your .m2v file and your .ogg file into the same folder
You should now have a .m2v file, and an .ogg file. Make sure that these files are located in the same directory and that they have the same name except for the suffix. For example, you could have a video file called mymovie.m2v and an audio file called mymovie.ogg stashed in a directory called stuff.
