best quality movie export for broadcast

Will I get a better result if I export my Toon Boom animation as a Flash movie, then import the Flash movie into Flash, then export a Quicktime from Flash?
I have scanned and vectorized clean inked draings into Toon Boom. It all works well in Toon Boom, but the export to Quicktime from TB looks more jaggy than an export to Flash. My final version is expected to be end up on SP Betacam od Digibetacam. Is DV PAL on TB good enough for this?
All the best
