444 to DPX and keeping TC
Hello,
We have a bunch of footage shot on the Alexa which is Apple Pro Res 4444 and we would like to convert that to DPX sequences. Is there a way to do this and still keep the timecode from the Pro Res stuff?
Thanks,

Actually, there were a whole bunch of timecode-related improvements [link] in AE CS5.5.
I haven’t upgraded yet, so I can’t test this for you, but if you have CS5.5, you could try it in AE with a quick clip.

Okay, thank you. I haven’t upgraded yet either, but I’ve heard there were several TC related upgrades.
Changing the subject a bit, but how can I export a DPX and keep it 444. I’ve tried exporting using 32bit thinking that would keep it 444 but it doesn’t seem to work. Any ideas?Thanks!

What exactly do you mean by “444” in this context? If you’re working with RGB DPX files, there’s no chroma subsampling and 4:4:4 is meaningless.

Hmm, We have a venue here at Universal Orlando that uses a DVS video server that plays 1080 60p DPX frame sequences with 444 color space.
There has to be something to make these files. I have an Intensity Shuttle that captures via HDMI as DPX files but I don’t know what the color space is. What do you play these DPX files back with? -
Hi Samuel,
My DPX package will preserve the bitdepth (the “444” as you put it) and the TC. If you are using LogC footage, it won’t touch the Log data, either, preserving the data as it goes into the DPX file. My software will also properly create the DPX header, too, indicating it is LogC data.

TC is still completely broken in AE CS5.5, or at least as far as reading and writing QT files is concerned!!!!!!!!
