Opinions on AG-DVX100

[Ed] “Michael,
You’re still recommending SDI after the posts to you about it in the AJA IO forum? 🙂

Tim,
Check out the Adam Wilt and Graeme Nattress links about DV and SDI here:

Given budget and equipment restraints w/regards to my (shoestring)project, my intended content path looks like it will be aquisition on the DVX100A..playback for digitizing on a Sony DSR-1500a component video into Media 100 v6 at (at least!) 150 kb.

When done complete, it’ll be mastered component out onto Beta SP.

Somebody ruin my day and tell me this AIN’T gonna work very well, cause I don’t know what I don’t know.

Thanks (I think)

Absolutely. Any time you render, add a title, nest a few layers, export a clip, you’re going to dirty the image. The DV codec isn’t clean. We just went through this! 🙂

If you capture SDI uncompressed when you conform, that is, when you’re show has been offlined, and you’re ready to color correct and master, you want the best image possible. Cut in DV, fine. Conform in uncompressed. Absolutely. This isn’t a wedding video for gosh sakes! It’s for broadcast. It’s going to be tech-evaluated at some point.

Check with the stations that are taking the video. Some won’t take betaSP as a master. You might, just for the conform, want to dub out a digi-beta master (rent one for the day you are mastering), then generate your subsequent masters from that. At least you’ll have a good archival copy of the show.

Now as to your question, the 1500 is great for playback. Since you’re capturing component, you’re not going to be working in DV anyway, so don’t worry about the codec issue.

Still check on the delivery format with your stations, and consider a Digibeta master for an archive. Expensive for a day, but you’ll be happy in the long run.

[David Jones] “Which board are you using in the Media 100,
The 601 @ 640 x 480, or the P6000 @ 720 x 486?”

David, I believe I’ve got the 601 board 640 x 480.

What I am most curious about is why you are limiting yourself to 150kb on the Media 100? 150kb is 4:1 compression. With Version 6, you can take it up to 300kb (2:1) compression. Is it drive space? Drives aren’t fast enough? With inexpensive Firewire drives out there, neither reason would seem to apply…

Lawrence, Drive space is the prime consideration. Given this could be a 30-60 minute show, I’ve only got 32 gigs of drive space available on the system. At this point, I’m now leaning towards compressing at 200 kbs. Admittedly, I’m not discerning much difference between 150 and 200, but I’m thinking I’ll give the benefit of any doubt to the 200 kbs setting. I just don’ think I’ll have
enough space at 300 kbs.

Finally, and I would be interested in your thoughts, I’m not sure my legacy system (M100 v.6 running on a 200 mhz Mac Power PC 9600) will handle a firewire device. I was told the firewire needs to be part of the M100 card.

What do you think?
