Need help for switcher

[zactommo]

The SE-500 is a lot simpler than the MX-50, which is good in a lot of ways. Its also a lot easier to not stuff up your cut on an SE-500, and the SE-500 doesn't soften your picture like the MX-50 does!

You can get external luma/chroma keyers, so its a viable option to feed the output of the SE-500 into an external keyer.
