Want to capture HD quicktimes on PC
We are capturing from D5 on windows XP and need quicktime files to hand off to another application. From what I’ve read it’s possible to capture ntsc and pal to Quicktime using the Deck Control utility but not HD, is this really the case? (https://www.blackmagic-design.com/support/detail.asp?techID=101)
If HD quicktime capture is not possible I was wondering if there is any quicker way to convert avi files to quicktime without rendering in after effects or some other application, which is really slow, I know the framelink utility causes avi’s to appear as dpx sequences and vice-versa and was wondering if there is a similar trick with avi’s and .mov’s ie just change the header information or something without rendering every frame.
Any suggestions? All help is appreciated.

You can capture HD with decklink deck control just fine even if you dont have AGP/PCIe graphics card (in this case you just will not see the live preview on your screen)
Other thn that you should be all set

In windows ou can capture various HD Quicktimes but not compressed PhotoJPG. If you have Blackmagic card, look at Easy setups at DeckContol, there are 18 different HDTV setups, all are quicktime. At the moment DeckControl captures only Quicktimes. But Quicktime to dpx, no, I miss it too.

Hi Kaspar
Can you mount QT-movies to dpx files in Mac? In PC only avis seems to be mountable. I didn’t find anything about Framelink in Blackmagic new manual (jan 2006).

hmm to think of it I have not tried the frame link on win machine – on mac it works fine on quicktime
Unfortunatly I do not have a PC workstation anymore so cannot confirm or daeny anything-Kaspar

I wasn’t able to mount quicktimes as dpx on the PC, actually I wasn’t able to mount avi’s either but at least it seemed to start the process with them before giving a “Try again later” error. The manual is pretty vague about the Framelink application, at first I thought it didn’t need to convert anything, just tricked the system into seeing individual frames instead of a video file but after playing with it a bit it seems closer to making an image sequence into a quicktime and saving as a reference movie, anyone know what I mean? If I could get it to work I might understand it better.

Hi,
I tried the Framelink AVI to DPX mode on a PC and it worked quite well.
However I would not try to do this to long AVI sequences because when you mount the
DPX disk and begin to read the frames in another application what you are actually doing is create a bunch of new frames in a temp folder (see settings or preferences). So if you want to read 20 mins of DPX frames you
will end up quickly creating another few hundred GIG (in HD) of data on your drives.The application seems to be really useful when working with single shots not so much for longer form work.
I spoke to BMD about this and they thought they could get the frames being written to the temp folder to inteligently cache only x amount of frames around the currently read frame. IE frames outside that area would
automatically be deleted. I dont know how far they got with this.It would be really cool if they could just capture Image sequences DPX TGA TIFF OpenEXR direct.
I might try and start a poll to see how many people are interested in this.Adrian

Amazing!! Just yesterday in our place we were discussing how nice it would be to capture straight to dpx!! I think the bluefish cards can do it and that’s what made us think of it. Transcoding is such a pain!!
