You can get desyncs on your own movies, but it's on the rare side (or else TAS's would never get made), and it depends on how good the emulator is and some on the particular rom. snes9x for mac has supported movies for a while I think. I think the first link is only a Windows binary, so if you have OS X, you want to download the source and compile it yourself, or look for a Mac binary that may or may not exist. The version of ZSNES you want (it's guaranteed much new and improved over what you have) is here. The best part about nitsuja's emulator versions is that they tell you which rom was used, if yours matches, and saves what settings the guy who recorded used, so that it can automatically set yours the same way. In snes9x, I've usually had luck with fake mute off, WIP timing on, and sync to sound CPU off. For settings, default has the highest chance of working. I know Saturn had an old version posted here it is. For the movies on, or other older things like Super Metroid vids, use an older version of ZSNES like. If there are multiple versions (like 1.0 vs 1.1) you might have to guess. Usually it will be obvious which region version you want. These will often have a ! in the filename. If you don't know this, typically for the roms, you want the 'good' (as in goodSNES) version. To prevent desync, the best way is to find out what emulator version and rom version were used. Might be hard/impossible to notice normally, but obviously it will matter on something as precise as movie playback. a lot of these have to do with sound emulation, so if you're only recording for yourself, you can try with sound emulation off), or rom versions. It happens due to minor variations in timing between different emulator versions, different settings in the emulator that affect timing (such as WIP timing and fake mute in snes9x. This is called desyncing and it's normal. Theres also the controller bug but I have a USB program that gets past that (I've turned it off and tried the normal method for control configuration for recording movies, still no go).

I've been having alot of problems with the emulator lately, the freeze states only save and load from the 3rd slot (out of 12). mov file that encodes at around a whooping 40 MB per minute of video :(.

Snes9x has movie support, you can currently export vids in a quicktime.

While some games start off ok for alittle while (super mario world lasts about 10 minutes), other games take a dive right away (Super Puyo Puyo 2 Remix). It should have enough CPU, I'm running it fullscreen with no other apps open. Well, I'll record it myself and replay it right after I'm done and it'll screw up after a little bit. also, i had no idea snes9x mac builds supported emu vids now. also need to make sure there's plenty of cpu time for the emulator. Need the same version of the rom and the same version of the emulator as the video was recorded on.
