Best recorder for Snes9x/ZSNES?

So here's the issue:

All of the videos I put on YouTube (Channel: HoD Hacking) were made using SNES9x's AVI recording feature, using Full Frames(uncompressed).

This has got a problem with videos going over 2GB, like my newer unreleased videos. I got options there like the one mentioned above, Cinepak Codec by Radius, Microsoft Video 1 or Fraps Video Decompresser(doesn't work), but the quality is too bad/the movie is not being recorded at all for average standards.

I have tried various methods, such as AVI Joiner programs but nothing seems to work at all.
I have heard of screen recorders such as Xvid and Elgato[correction probably needed] but I don't feel too safe downloading them, so I cane here in order to get advice from a community which makes SNES videos frequently.

Nowadays I use Open Broadcasting Software. It works fairly well for me.

I quote Lockirby2, the other thing you can do is using Freemake video converter, that will change your clips from AVI into MP4(anyway the first solution is faster)

Open Broadcasting Software doesn't work with Windows XP, but I found another recorder anyway. Thank you for your support!
