Most people use zsnes for their recording.
Use snes9x. You can find it in the tool section.
With snes9x you can make much better movies and quality is much better for videos.
Open up Snes9x and your rom.
Go to File > Movie Record
You can put the movie file where ever you want. And any name
And use these settings. (I always use those)
Then you see that there stands Movie record and Frame.
Play the game with save-states (You don't need to)
When you're done playing
Go to File > Movie Stop
Now the "boring" part
Pause the game with the pause button.
Go to File > Movie play
Search your movie file. Play it
The movie should be paused!
Now go to File > Record Avi
Save it under any name
I recommend you to use:
CamStudio Lossless Codec v1
You can try every one you have, to see which is the best.
Let the movie play.
If it's done
Go to File > Stop AVI Recording
Go to Youtube, upload the AVI file, or use Windows Movie Maker to make it smaller.
Upload to your video hosting website of choice.
Embed it to use it on SMWC
