You'd be right in thinking that this is a frequently asked group of questions, The answers are as follows:
1) AlamDV3 is due out soon, whilst I can't comment on the progress of the beta testing, I can point you to the to-do list which should give you a rough idea of the programs in-code progress.http://fxhome.com/forums/viewtopic.php?t=16747
There are many updates as to the programs progress as well as interesting examples of the new systems in place for the new program such as the flare engine, demonstrated recently here:http://fxhome.com/forums/viewtopic.php?t=17264
2) Losing quality due to use of Microsoft DV codec is a problem experienced by quite a few, but the solution is beyond simple. Don't use the Microsoft DV codec
you can export to a normal uncompressed DV in many programs, And if not... downloading the Matrox DV codec and exporting to that will enable you to work with full quality footage.
It's worth noting that AlamDV3 will work with the Microsoft DV Codec.
3) Embrace the program.... You wait til you see AlamDV3, muscled men will have to hold you back from kissing the CSB team.
Asking questions about the programs here won't rub people the wrong way, though you could have found all the answers to the questions you asked by simply looking or using the forum search function.
By answering your questions, I am hoping that other people will find this post in their search results.
Take care, I hope I've helped.
