Now I'm sure if you want to do anything serious this will be a heap of crap
Dunno... I did a proper wedding video for somebody with my Samsung cam a couple of years ago, and that cam was the cheapest of the cheap at the time.The results were great. Most of the quality when you're doing anything 'serious' is down to the way its shot, and the way its edited. My camera was mounted on a tripod so no dodgy camera shake manifested itself. All the panning and zooming was carefully done and nice and smooth, and the full edit took me two days.
This does remind me of another problem I had, though. On the day, I used three tapes on long play - the quality was still good enough as it was only destined for VHS anyway. But, a big problem I encountered was that I had to remove the tripod mount from the camera - it was impossible to open the tape compartment with it on. Minor detail, but it was very inconvenient for what I was doing. It turned what should be a ten second job into a couple of minutes.
