Primarily because it will name the actual DV files as per the shoot date/time. I can then keep track of the appropriate chronology of events which is a frequent requirement for me.
With this date/time filename ability, one could also take footage from multiple cameras, dump it all in the same directory/folder and it is (correctly) sorted chronologically. Makes things easy when brought into Vegas and placed in the timeline. All is in order.
Also, being able to index the DV tapes makes finding stuff later much easier.
I mentioned time lapse from Scenalyzer. I shared a time lapse that I did with Scenalyzer many years ago. I just found it in an old archive and wondered if I could share it directly using Photobucket, rather than using YouTube. Here's the link and we'll see if it plays (this is more of a test for me, since I don't think the original poster had any interest in time lapse):
[edit] well that answers the question: Photobucket videos do not embed; only YouTube and Grouper videos. No big thing, you click and it takes you to Photobucket and it plays immediately.
For DV, I've never had any problem with Vegas VidCap. However, I use Scenalyzer for all the reasons that have been mentioned, primarily the file naming options. There is absolutely no difference in the video quality using either application.
For HDV I've know some others on the board use PPro. I like its capture program if you have because you can batch capture.
But, on my end, for whatever reason, Vegas does not handle HDV captured from PPro very well. Also, again at least on my computers, the windows explorer represents them with two different program icons (Vegas is WindowsMedia, and PPro is Nero).
I wonder why this is?
Doesn't matter for me know, as I am converting everything to Raylight to save headaches later.
