digital/strobing look

I am really impressed with the DVX100a and hope to own one soon. I just got The DVX DVD with the book as well as ART History from Goldstar Productions. I wanted to see what the camera is capable of and learn more about it. Both were great; however, I want to know why there is a lot of noticeable digital blurriness on the DVX DVD when the ladies speak (their lips) and move their arms around. Other than that the shots were great. On the Art History DVD I did not notice digital blurriness. Once again both were great. Thanks for any explanation.
 
Have you tried getting your eyes checked at lens Crafter?


I'm just playing with ya. Yeah, like SD said, it could just be compression or progressive scan playback.
 
Bad mpeg compression, huh. I've had similar problems with consumer level cameras. I guess what I really want to know since I've never touched the DVX100a before is if this is just limitation of the mini DV format/the camera itself or is it the way it's compressed onto the DVD.
I just don't want to be disapointed if I buy this camera, film, then have all my footage turn out with digital artifacts. The shots overall from THE DVX DVD were beautiful, very well done. Maybe its just my DVD but the depth of field scene for example has little digital glitches around the mouth and the movement of the hands. Barry maybe you could help out here. There has to be a solid technical answer for this. Is it the camera/ the format/ or the copression to DVD?
Thanks
 
the DVX is as good as any other miniDV. it sounds like a problem with the DVD you got. artifacts around talking lips are not a DV issue.

It has nothing to do with the camera. The mpeg compression comes into play after the video is edited and compressed to mpeg for recording onto DVD. I'm sure the raw DV avi file looked great.
 
Thanks everyone for taking the time to answer my question which seems a little silly now that I think about it. I'm now convinced the DVX camera is for me. While we are on the topic of mpeg compression issues...How do you make sure the mpeg 2 compression comes out good?

As a rule of thumb, the higher the bit rate, the better. For better compression quality, avoid repeated quick cuts (especially those that are shorter then your GOP size, typically 12 to 15 frames), as well as fast pans for any prolonged periods of time.
