Jitter Questions
Posted: Sat Mar 18, 2006 1:07 pm
Since I purchased the dw1655 to help with the scanning of my archives I have been paying more attention to jitter. I rarely scanned in my PX-716A since it is my video production rig and my DRU-710A did not measure jitter.
From all the reading I have done a good rule of thumb is 8% or less based on the DVD spec but it also depends on how your other error rates look. I noticed that the PX-716A routinely produces discs with Avg <8% jitter (but just under 8%) but spikes to 11% at times. The dw1655 produces discs with Avg <6%.
So my questions:
1. From practical experience of the users here, how much it too much jitter to hinder play back or just reading a disc on a computer?
2. Can PC drives compensate better for jitter that DVD players? (my gut says yes).
I create 2 kinds of discs. First DVD movies of course and the second in raw footage archives in UDF format. I am thinking I do not need to worry as much about jitter on the data discs.
I do not want to overthink this but just want some help with some good guidelines. The forum here has helped me so much with drive selection and technical questions I really appreciate it.
Here is a typical scan with my preferred media, burned in the PX-716A and scanned with the dw1655.
Thanks.
