Re: Source window and Program window issue.

You can't change the sequence settings once they are set - you can only create a new sequence. It makes sense that HDV would not be available in the trial version. Probably no P2 or XDCam either.
However. You can create custom settings with the Microsoft Uncompressed AVI codec or what ever works. Then you can export from that to whatever codecs you have available in the trial version. That way at least you aren't down converting your HD animation to SD as a first step. Please note that encoding video is part science, part art and you may have to experiment with different settings to get good results. It is possible to get really good results, so if looks bad, it's your fault, not the software.
