Working with 2k files from a telecine…
Mornin’
I’ve got a disk full of sequential .dpx files from a telecine of 35mm material. I’ve got a pokey MacPro with FCS 2, some G-Sata drives and a AJA Io HD.
But I havn’t got a clear idea of what to do next!
Just want a reasonable hi quality set of rushes to play with – not to go back to film, but which will do the material justice.
I was thinking of ProRes, but I’ve not used it before.
AJA have an app which will turn the .dpx frames into a Kona 3 10-bit Uncompressed quicktime movie…but where do I go from there?
Any help or pointers greatly appreciated, brownies mailed within the UK!
All the best

you are never going to see files in realtime without fast enough storage- those DPX files need something that can read and write at over 250 megabytes per second…. or about 4x faster than those Graids.
About the only thing you can do is convert your files in QT to be something much smaller – say 720p24 to be able to play off those drives,and be prepared for it to take a very long time, and blow the TK away in the process.
Your IoHD will not playback 2K DPX streams.

Hello Gary
Thank you for your time! I did sort of think that the drives would choke…
The scary thing is that 50 frames of dpx, wrapped as Quicktime even manages to kill Compressor on my machine!
I’ve no illusions about the loss of quality but which codec would you recommend I use from here?
All the best

Welcome to 2K…
this is not a format for the faint of heart or those caught in the wrath of weak processors.
Use the QT player, it is far more stable and it supports frame natively ( open image Sequance) then convert.

Hi, one way is to use the AJA DPXtoQTT converter to make a .mov.
Go to FCS and change the Sequence Presets to your desired ProRes configuration.
Import the .mov and drop it to the timeline, and don’t allow FCS to change the sequence setting to match the clip. This would letter box the material inside the ProRes size.
Export the timeline using Quick Time Movie and seletec the Setting matching your Sequence Preset for ProRes.
Your ProRes .mov would play using your G drives.
When you are ready to step up to DPX capable storage, check us out, the PRO DQ is very fast! Dulce also have FireWire 800 eSATA portable drives too.
