2.56 r7716 conversion result not as expected UPDATED

[ABBrittain]

See Updated files.

I've been running some est test and I've tracked it down to the default setting of the Target video size field.

I' unclear as to what this should be set to as to big a value just produce to large a file and to small a value just error and the conversion stops. I know this should be set as small as possible.

Can anyone suggest how to set this up.

thanks
