Compressing DV tapes
There are around 40 DV tapes that I recorded for a project I am involved in, and I would like to make some DVD working copies.
The backup copies I had done are in VHS, and are a burden to carry around. What I wonder is which would be the best way to compress the DV captured material onto DVDs, say putting 4 or 5 hours on each disc. Of course I am aware that quality, particularly image, will be lower, but I do not want any artifacts. Which would be the best way to do it? What I need is a video I can play on any DVD deck, not just on a computer. If that were the case I would simply use Divx. The program I was considering for this task is DVDShrink, but I wonder if there are other better choices. Suggestions? Carlos |
First of all, you need to render to MPEG2 for DVDs. The bitrate used will determine the amount you can get onto one DVD. You can look at Vol 1 #7 of my newsletters to get more information and find a bitrate chart.
Natrually, the lower the bitrate you use, the worse the resulting MPEG2 file will be. Most people generally hate to put over 2 hours onto a single DVD. If there is not much movement in the video, you may get by putting more onto the DVD but 4 - 5 hours is really pushing it past the extreme. All I can recommend is that you do a few test runs to find your acceptable quality limit. |

Thanks, Edward. I will have a look. There's very little movement on this stuff, as it's mostly interviews. How much would you say I could stretch the bitrate and get reasonable results? My idea had been to use DVDShrink to do the job, as I think it analyzes the image and does the best compression. Certainly doing several tests is the way to go about it. Carlos |
Have you thought about using a dvd recorder? Many of them can take a firewire cable and can be set to record 1hr, 2hrs, 4hrs, 6hrs etc...
