opinions on conversion quality dvd vs betacamsp |
|
|
Hey all,
I'm getting ready to master for a huge duplication run of dvd and vhs.
The dvd is no problem as they simply duplicate from my authored dvd. My
question is trying to get the best quality out of the vhs duplication.
So really I'm compairing dvd (mpeg2) to composit betacamsp for
mastering. I can also send in DVcam and Digibeta (i think). The dub
house prefers betacam but if mpeg2 is comparible wouldn't it be better
to keep it all digital?
Thanks in advance.
Bruce

"Digital" does not mean "better". I have a digital camera that takes two kinds of pictures - crappy and very crappy.
Digital is supposed to suffer no generation loss, but in video =editing= (as opposed to copying) this is not true, since images have to be decompressed and then recompressed when editing in most cases.
I'd go as far up the stream as I could. The DVD came from some other format (a betacam master? A Digibeta? DVCam?) Whatever was used for the master of the DVD will be better than the DVD itself.
When you say the dub house prefers betacam, see if it's digibeta or the older betacam. An advantage to a digital master is you can send a copy of your digital master and it's just as good. A copy of an analog would not be, and if you are doing a
big run of VHS, you'll be playing the master a lot. If the original master is analog, I would make a high end digital copy and use that (digibeta, for example), assuming economic factors are not significant.

My mistake I should have been more clear. I shot on betacamsp, digitized
all the footage and edited on FCP. I'm just looking at a output solution.
the dub house requested betacamSp analog. I'm able to make a digibeta
dub but it would go through firewire.
Thanks,
Bruce

Ok, so the original (finished product) is in your computer. I wonder if they can dub from your hard drive.
I don't know what the losses are through firewire to digibeta, so I really can't venture a specific opinion I'd have faith in. Maybe somebody else who has more experience with these specific formats will chime in.

VHS duplication ..
I doubt you will see any difference between a Digibeta and a Beta SP for
dupes. If you shot on Betacam SP.
I would always send the highest quality uncompressed master to the dupe
house. But with proper bars for sure! If the bars are off the copies will be
off. |
