Hi Luke

A specific feature that would help me a lot would be the ability to capture in Decklink Extreme / Windows into a DV format – so that Betacam material (mostly archive now) can be easily incorporated into DVCAM projects. At present this involves a messy capture and recompress process, slowing editing no end – and many projects do involve sourcing from multiple formats, including firewire as well as Decklink formats.

An alternative would be the ability to mix DV and BM compressed material on the same timiline.

Paying extra for a third party DV codec if needed shouldn’t be a big issue, if the Microsoft DV codec can’t be used for some reason. I gather MainConcept’s codec is around $50 or so and is reported to produce good results.

Some kind of interface in the capture process allowing for selection of codecs existing / accessible on the capture machine would do the job. No need to worry about compatibility on transfer out: it would no doubt mostly go out as tape or Mpeg2 file, and anyway would be up to the user to ensure playback compatibility for her/his output ..

Thanks.

Mike,

I hope you are referring to the capture in Premiere or Vegas ?

Using the DeckLink Deck Control you can capture straight into a DV .mov. Only thing you must do is to set the quality bit using QuickTime PRO.

Hi Yves

Yes, in PPro. I’ve tried capturing quicktime DV files, which works – but they don’t edit well in PPro. Apart from not playing out from the timeline in DV avi projects, there is also some sort of colour shift that occurs going in and out of dissolves or other effects.

What would be nice – a seamless workflow, capturing from Decklink or Firewire into a DV format – good enough for nearly all of the corporate work that I do – so that clips from either type of source can be edited and played back directly, without a render stage …

Of course if there’s a software editor that offers that today on Decklink (and not TOO costly) then that would be worth exploring. I’m not aware of anything that does that.

From here, it seems the neat solution would be for the decklink to offer capture into DV avi – using codecs already on the system or from whereever. If the system is fast enough to read the incoming Decklink files and compress them on the fly, then we’d be in business … or am I missing something?

Luke thanks for the reply.

I was anxius about the next release primary because of the color shift between 2 8bit clips inside premiere. In realtime it’s ok but when I render the FX it has a luminance shift. Even when I try to use a title the clip underneath is shifted noticably.

Also I can’t use the rendered Combustion Avis with any of the blackmagic codecs, so I have to render a sequence and the re-render it to a QT movie from within After FX. Two renders is a waste of time.

And finally in PPro when I print to tape and have forgotten the curson in a frame inside my edit (not a black one) Decklink starts to print to tape but uses this frame for the first frame of the entire movie and shifts the rest of the timeline by 1 frame (it doesn’t un-sync though). It’s like the framebuffer does not clear when it’s exporting (not until the deck goes to rec mode).

I’ve already asked these questions since 4.7 drivers and I hoped that there would be a fix in this release.

Again thanks for the reply

You can change the setting in Premiere to shift the video by 1 frame. (It’s named “quarterly frames”, somewhere in settings, I have to use -4 for 1 frame).

I still have a problem in that it REPLACES the first frame now, meaning it cuts off the first frame and replaces it with that framebuffer frame. I just place 1 frame black in front now…
