DNxHD for filmout? at DVinfo.net

Hi guys,

I am currently making a feature for theatrical release, and has finished the offline. We shot the film on the Sony HDCAM F900, and I am getting conflicting advice on how we should do our online.

We edited our offline on avid xpress pro HD. Our post-production supervisor said we should finish the online on avid adrenaline, using DNxHD codec for finishing.

Another technical friend of ours told us that we should do the online on uncompressed HD as our final output is for film and we should not have any compression.

Both insisted that their way is the proper way, as our post-production supervisor said there is no noticeable quality difference between these 2 ways. Will be great to get some advice here. Anyone can help me on this?

I would always think that no compression is the best. The Avid codec is great but and if tape is your final output than you will be fine. Are you blowing this up to 35mm?

If you are, the best advice is to call the place that will do your transfer and ask, as I am sure they have experience with both options.

Another consideration is costs. What is your uncompressed option? I would bet the Adrenaline is probably half the price as any uncompressed option.

Hi,
Thanks for the feedback. We are working on limited resources, and we plan to output the final film in hard disk and blow them up to 35mm.

We are working on limited resources, and if the DNxHD codec is good enough for film blowup, we'd prefer to work on that.
Will be great if anyone has suggestions. Thanks in advance.

you might ask a media to FILM transfer house - as they are doing the transfers ...

the DNxHD codec is good enough depending on the bit rate (it has different bit rates you can use)
