Capture Macrovision stream?

TeetimeNC wrote on 6/18/2008, 8:15 AM
I have a client who inadvertantly videoed an event with Macrovision DRM turned on. This was with an Archos camera. They can play it back on their Archos 504 player. They need to get the video into Vegas for editing. My question: if I connect the player to my computer via DV passthrough, will I be able to capture this video in Vegas? I am assuming I can since they can video out to a TV. Is my thinking correct here?

Possibly use DVDShrink (or the like) to bypass all protection? Not considered illegal at all, since they own the footage. :)

Canopus ADVC-100 and 300 will also strip it if you hold down one of the buttons for 20 sec.

I have an ADVC 300 which I can try when I get the footage. But, wouldn't it already be stripped in the video out from the player?

I am hardly an expert on Macrovision, but my ADVC 100 will strip out 1 certain kind of Macrovision, I think Type 1. There is another kind (I think Type 2) that it will not strip out.

Works on one, but not the other.

Unfortunately no. Macrovison is an integral part of the video signal (part of the vertical blanking interval) and, as such, isn't stripped out by doing this.

Anything with a good timebase corrector will remove it. The ADVC 300 could but it has a Macrovision detector that'll cause the unit to stop processing video. There could be a back door to turn th detector off because of the problem of false positives.
A Sony Digital 8 camcorder or VCR that does pass through will strip it off as will any stand alone TBC.

Another way to remove it in Vegas is to simply crop out the top 4 lines or so of the frame. The Macrovision data lives in this area. Crop it and it's gone.

The canopus units do have a backdoor to turn off macrovision detection. You hold one of the buttons down for 20 secs. I don't know if it works with all kinds of macrovision, it's been a while since I tried it.

How's that going to work if the Macrovision stops you capturing it in the first place?

Chienworks wrote on 6/18/2008, 5:28 PM
It works fine with the SONY converter box i use. It has a signal to tell you if the video is macrovision encoded, but it still captures anyway.

Thanks to all for the great insights.

Kelly, I don't get the footage till tomorrow, otherwise I would try this now - I have an old Sony TRV120 that I have used for passthrough. Do you think it will strip Macrovision during capture?

That'd be because it's got a TBC in it. I think the Macrovision flags would be outside the picture area and aren't in the captured DV so cutting lines off the top of the picture might be pointless.

Well, i know the DVMC-DA2 doesn't have a TBC. When i capture macrovision encoded material there is a row of colored flickering dots on the top 3 lines of the frame. If i crop these out and print back to tape the macrovision is gone. If i leave them in and print back to tape the macrovision is still there. So, evidence suggests that it's there in the frame.
