Hi folks,

Maybe someone can help me out. I shot a short film on 35mm. Unfortunately we could only transfer to HDCAM (not SR). We imported the footage compressed for editing purposes. We will upres again from the HDCAMs for color correction. The movie has been edited on Avid and we want to color correct now. We are finishing on HDCAM again.

We have access to an AVID DS (Nitris). At what settings should we upres the footage again? Should we generate a DPX file for the DS? Is DPX overkill? HDCAM is only 3:1:1 140mb/s. Couldn't we just use like Avid HD DNX 220??! It's a higher compression setting than HDCAM anyway??

What about using Apple Color instead? Exporting from Avid as an Avid DNX quicktime and then importing it to Apple Color and finally laying it back out to HDCAM from Final cut...?

A little unsure what would yield the best results or working space.

Hope someone can help out!
Thanks

The first things to ask are what you want as your final product, and how much you can spend. If you want film, perhaps trace back and either cut the neg or scan again in 4K? (It depends if you need the control that DI gives you.) If you want HDTV, perhaps online and time in the same 8 bit 3:1:1 HDCam?

Unfortunately we can't go back and rescan. No money. We have HDCAM and need to finish HDCAM. The question exactly is what is the compression format to get all the info from the HDCAM without generating an unreasonable large file?

In that case, I'd go DNx220, using the Avid/Nucoda combination. Try Roush in Burbank, they specialize in that for indies:
