I dont know about that product, but I can WHOLEHEARTEDLY reccomend Sonys "Screenblast Movie studio"
Its rock solid and stable, has pleanty of effects and stuff, and is east to use. Its only drawback is less than spectacular encoding speed...but heck...I can take an extra 20% time for encoding for the programs overal quality.
I can also scream at the top of my lungs never ever ever ever under any circumstances not involving the death of a family member never ever support Pinnacle. They have shleped out 2-3 years of the most crappy assed crash happy software ever concieved. Ive seen viruses that were less annoying. Their support will blame everything on the planet for the issues (well everything but their software)...but after attempting to use it on 4 computers both AMD and INTEL with both Nvidia and ATI and both Nforce, Hercules and Creative labs and everything in between....it is clear their software crashes as a FEATURE and not an exception. Some review sites gave it RAVE REVIEWS, and apparently were either paid off....didnt actually run the program or only delt with very small files....after 2 years...I have never succefully encoded a video longer than 4 minutes on Pinnacle...and that 4 minute avi was at the expense of (scouts honor here) at least 100 crashes while adding video clips, audio and encoding. I litterally save after every single thing I did....else you lose 5 minutes of work on a regular basis. And before anyone asks...yes, I did EVERYTHING support said to do...and it made absolutley ZERO difference in crash frequency or severety.
So in a nutshell:
Sony Screenblast: YES!!!!
Pinnacle Studeo: NO NO NO NO NO!!!!!!
Blazemp: No idea....but will check out!
