vvvv isn’t missing something (indispensable) that td has and viceversa.
So, IMHO, people change because they know people using more often one tool than the other, or because they’re fanboys, or because personal taste, or because they find one tool more fitting to their knowledge, or because…
If you want to be a “multimedia” professional, you should study and practice software day and night. Time should be relevant only when it comes to deadlines (and you should have lethal deadlines only when you’re pro).
Doesn’t matter how you look at it, it’s hard work anyway…
Me neither, I just gave you the most honest answer I had in my pocket. It wasn’t what you expected, but believe me, it’s fitting to your question more than one can get at first glance.
And in any case…For example, everybody here says “no way man, go full vvvv for this, this and that reason”, then one day you’ll find that td it’s the best for what you want to do… Who to blame then for all the time spent on the wrong tool?
