POLL – who would use DPX or Image sequence capture in Decklink.
Hi All,
I thought Id start a little Poll to see how many people want to use image sequence capture support within Decklink Hardware.We know manufacturers such as BMD do resond to their clients wishes. so what better way to see if they should spend time towards developing such requested tools.
# Do you want Image sequence capture support?
# What Flavor – DPX, TGA, TIFF, OpenEXR, JPEG2000. Other.
Instead of turning this thread into a political discussion of why or why not or anything esle please start your own thread for such matters.
I think the best way to get the thread going is to just reply if you agree with the idea that Image sequences should be supported and add the flavor of support at the end of the subject line.
Perhaps if you visit other Decklink forums elsewhere on the web you may want to post this there as well
so as BMD can get a true response.If there is no or little response then…… ummm…… Ill stick with my horrendously slow QT or AVI to DPX renders
for a short while and see what else is out there.Thanks,
Adrian Hauser.

DPX would be great – jpeg2000 and I will dance naked around bonfire 😉

why not use the FrameLink software that comes with your BMD card to get instant access to DPX files? The problem with image sequences is the editing softwarre we use doesn’t support it (on hte Mac side atleast, PC’s with Premiere Pro can use TGA sequences), FCP does not do a very good job of working with image sequences. There may be updates in the near future on the Mac side, that will enable Image Sequence work, but it will probably come a t a premium.

We could definitely use dpx, JPEG2000 would be great too but I’m not completely convinced the “Lossless” setting is truly lossless (anyone else play with it much?) The more options the better as far as I’m concerned, and yes image sequences and final cut pro are not a nice mix, I recommend trancoding to a self contained quicktime.
Transcoding is a pain, so is having to store multiple copies of lossless video so different applications can use it!!

Hi,
I guess a support for online jpeg quality is what i need, if i want to capture really long footage.thanks

i think dpx capture is a must but quicktime doesn’t support dpx i think
i hope we will see very soon support for sequences of image and real mxf
but i think it is more a problem for fcp than the cardi have another question why framelink doen’t work with any codec?

Hi,
Im breaking my own poll rules here but in a natural response to the above framelink query i cut out a prior thread.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.Im working in a windows environment where we need image sequences to help us with a di workflow, grade – despot – output files for film out. The better near RT despot tools ive seen for longform work are optimised for image sequences.

adrian,
what about cineform prospect on the pc side?

Hi!
We just used framelink to transfer a feature doc (HD 1080 50i) to DPX files for 35mm filmrecording and with such big amounts of data, working with framelink becomes very cumbersome. Mounting the virtually drive takes ages even on our Quad and dragging 150.000 frames from one folder to the next is extremely difficult as the whole finder becomes unresponsive.
Maybe Blackmagic could implement a menue dialogue system where one can specify where the DPX files should be moved to, rather than having to do drag and drop.
Anyway it’s a great little app that really helped us in our workflow!
Best
Georg
