Print to DV - copy inhibit

Tom Pauncz wrote on 6/28/2002, 8:38 AM

Hello,
First project completed with VV3 - short talent audition video. :-)
One question, the answer to which I couldn't find in the VV3 manual.

After the print to DV completed, I saw "Copy Inhibit" show up on the camcorder screen after the black trailer.

I did check and the video was printed to tape successfully.

Can someone explain what this is and do I need to worry about it?

Thanks
Tom

Most cameras, and video devices, respect several copyright formats for video. For example, Macromedia copy protection is used on many VHS videos. The cameras, or other devices, sense this and put the words Copy Inhibited over the top of the screen to make the copy useless. Something in your video must have made your camera think it was protected.

The Director's Cut box I got allows me to copy stuff that is protected, but I still only do it under the CVLI license that we have purchased. It was annoying to not be able to do it legally because the hardware was too smart.

Thanks Tom ...
I have no problem with your explanation, except that I had just created the project, was all my own taping and editing and the Copy Inhibit words showed up ONLY at the end after the printing to tape had completed.

My guess is that there was some noise that looked like copy protection to the camera. I don't know how the whole thing works, but I've seen similar occurances. I'm glad your video recorded first though :)

I believe that is Macrovision and I think it was Chienworks who figured out you can defeat it by cropping out the top few lines of video. I need to try this out on a video I recorded... an old animated feature from the 70's called Raggedy Ann's Musical Adventure. I had to pass it through my DVCAM deck and capture it to my hard drive, but now I doubt I can print it back to DV tape without 'fixing' it by cropping out those top lines. I could also probably purchase a special (hacked) remote control for my DV Deck which will disable the Copy Inhibit option on the deck and allow me to record even with the Macrovision.

Macrovision puts a spike at the front to of a frame which upsets the AGC on a video recorder causing the recording problems. Pass the signal through a limiter/clipper and the signal is fine to copy (for leagal reasons) also the good ol Panasonic AWE5 vision mixer will do the trick. the fact you recorded the piece of video means all is well and the signal you send to a VHS tape will noe have the corrrect signals.

Thanks for all the replies and suggestions. The second time I printed the SAME project (recorded by me on my own camcorder and edited by me and unchanged) I did not see the COPY INHIBIT stuff. As per a previous post, possibly some noise ...
