OMG, this editing stuff, is driving me mad, I think I'mm going to give up in frustration soon.

I've pressesed something whih has resulted in the preview screen becoming elongated at loosin the 'bin' window, and I don't know how to get it back, has naybody got any idea what I need to do to get it back ?

The second query relates to applying video filters.

I'm trying to make some yellow fish turn orange.

I've applied the Chrominance Key, and changed them by applying a White Ba;ance. but the rest of the back ground is black. Any ideas ?

Thanks in anticipation.
