Philip, > Using GRASP, you can then link the video back to sound. Please expand on this. What type of sound files are you using? How do you create and edit them? What audio hardware do you use? Thanks. Pete

Hi Pete, I use three different types of sounds. I use the PC speaker for special effects, I use a GRASP digitized (VOC or WAV) player for voice and effects and a MIDI player for CMF or MIDI sounds. In the example I talked about I used the PC speaker for a "cranking sound" that was in sink with the video clip (which shows a crank turning). If the clip was longer, I might add a Sound Blaster song by using GRASP's interrupt call to kick the Sound Blaster TSR (SBFMDRV.COM) into play. If I wanted to add voice, I might use GRASP's Realsound player to play digitized sound and video simultaneously. Finally, if I wanted a rich, orchestrated sound, I would use a MIDI TSR called PLAY/D that has a built-in interface to GRASP. Complicated, yes, but highly flexible. GRASP can play back each frame of the video in a loop…so I can speed up or slow down the video in relation to the sound. A format like AVI (Window's Audio-Video_Interleave) drops frames as the system struggles to keep up with the data rate. This is not possible with GRASP…although you could fake it. Understand that what I am interested in doing is bringing full motion video into the ANI/3D Studio/GRASP environment…not create a full motion 10 minute presentation…not enough hard drive space for that!
