Welcome to our community, Jason
If you want crystal clear recordings that play back exactly
as you recorded, you need to simply record a smaller dimension. If
possible, resize the browser or application to a smaller dimension
before recording.
Assuming that isn't possible, you have a couple of options.
1. After you record, click Project > Resize project and
shrink the recording a little. Be advised that this will have a
negative effect and your movie will lose quality. If you choose
this approach and aren't sure how much you will be scaling down,
always click File > Save As and work with a copy until you
settle on what works best.
2. If you aren't overly concerned about the loss of quality,
instead of using the HTML companion page, you could point directly
at the SWF. There are a variety of issues with this, but it does
work for some folks. If you still need or wish to use the companion
HTML page, you could edit the properties so instead of specifying
pixel values, it presents using percentages. 100% for example.
Hopefully something here either helped outright or caused you
to formulate an idea that eventually does.
