Sup peeps. Question for you guys... After viewing a video that I recorded using the 'Record AVI' function in SNES9x, the sound is always "scratchy" and "popping". Is there a certain sound setting that I must use for SNES9x to avoid this problem? Or maybe a certain compressor that I must use? Current commpressor that I am using is huffyuv-2.1.1. Current version of SNES9x is 1.5 Thanks for the help.

If you mean the AVI itself: There was a change to how sound is generated in Snes9x 1.5 (the original one with no Windows version) that breaks the sound in AVIs made in the Windows port. I didn't catch this until after 1.502. It'll be fixed in 1.51, until then you could use 1.43. EDIT: So apparently using FMOD sound driver sidesteps the problem, I didn't know that. If you mean while playing a game it's scratchy: Try changing the buffer length in the sound options, or turning off synchronize sound with CPU.

Yes, this is what I meant and thanks for the help and quick response. However, I did find that if I changed the sound setting to FMOD DirectSound, the problem is fixed. Thanks again.

I guess I'll just ask one more question. Is there a way to compress the video even more? After 2 minutes of recording, the file is around 700 mb.

"Even more" in which context? I'd recommend lossy encoding, x264 to be exact. If you want visually identical (quasi-lossless) quality, choose fixed quantizer factor of "0". Though I'd use something from the range of 18—24, that still doesn't produce disturbing artifacts but keeps the bitrate pretty low. Of the lossless codecs, huffyuv is the only one I know.
