WorkPrinter Now DV Compatable!!!!

[MovieStuff]

Ta-Daaaa!

It took some experimenting but the WorkPrinter now works perfectly with both DV capture via FireWire and analog!

Also, I am revamping the units for total commitment to quality final transfers.

Stay tuned for more information!

Hi Roger:

This is great news for me since I love DV for shooting and editing. My question:

Does the Workprinter does the Pulldown emulation for DV 3:2?

No, but I did reduce the frame rate from 6fps to 4fps to help those with slower systems. Making the 3:2 pulldown automatic during transfer would require slowing the WorkPrinter down to a crawl and would take longer to transfer the footage than to render out the 3:2 pulldown on the computer! Besides, there's always a certain amount of color correction to render out and the 3:2 pulldown could be achieved at that point.

Then I am confused.

DV codecs are fixed at 30fps (29.97 if you want to get technical ). If you capture 1:1 at 24fps doesn't the PC give you an error for unsopprted parameters for rendering.
My Canopus editing workstation would not allow me to render anything 720x486, 24 bit, 29.97 fps, etc, etc.
I have also done the same with an OHCI. Same result.
I am probably missing something here Roger. A little help would be usefull.

Thanx!

Hmmmmm. There must be different capabilities for different systems. For instance, one guy looking at buying the WorkPrinter says that the Canopus won't even DO single frame capture, therefore the 3:2 pulldown issue would be moot. On the other hand, Jeff Dodson (digvid) had my prototype for a while and not only did his DV system do the required speed change, it also did it in real time with no rendering!

Unfortunately, I am not an expert on miniDV. Are you saying that it won't do the speed change at all? Or are you saying that you can't RENDER a new clip with the speed change? It would seem to me if it will make the speed change, but without rendering, then all you'd have to do is lay it off to miniDV with the speed change in place, then re-digitize that tape. There shouldn't be any generation loss.

Maybe I'M the one missing something here! Any additional info would be helpful.

Roger I think I realised the problem/difference.

Basically, if your firewire card/NLE supports stop animation capture it would work. Since there are a million ways a company can implement such a basic function, you would be tearing your hair out pretty quickly in getting it to work.


Best bet is to use OHCI standards. Meaning test your system using Premiere 5.1/6 and an OHCI compatible firewire. This way its easier for you and a OHCI generic firewire card is only about $50- very affordable.

My friend did the OHCI test NOT with Premiere, but some other software. I think if you use Premiere and an OHCI card, the stop animation capture will be supported, the speed change render will be automatic and you will only need to deal with one kind of driver (which is included in Direct X version 8 or Windows XP).

I do not have access to a Premiere/OHCI system right now so I cant test. MAybe someone in this board can.

as i understand it, the workprinter captures 1:1 at any frame rate you set in your stop motion capture software. for dv, this would have to be 29.97 (or 25) fps, so the footage will play too fast on your computer unless you slow it down and render with pulldown. you could always capture with some other codec too and set the frame rate to the same as you shot at (18 or 24), but then you can't use your video monitor while editing.

Exactly. Thanks, Mattias.

The idea is to capture at the standard 29.97 rate (one frame at at time) and then simply tell the timeline to play back at 80% using the speed effects filter, NOT the overall project settings for frame rate.
After I read the initial post by crimsonson, I checked with a two people that have DV boards; one is a Pennacle DV200 and another is a StudioDV, also by Pennacle. Both will allow for changing the speed to 80% on the time line to render the 3:2 pulldown. However, one doesn't CAPTURE at 24fps in the stop motion mode. You leave your capture and playback project settings at the original 29.97 rate.
