Is native prores stable enough to edit feature film? Or should we go dnxhd?

The Alexa shoots Pro Res 4444, correct? There does not seem to be an option to import or transcode to Pro Res 4444 MXF…there are only the other flavors of Pro Res. So you will be re-encoding no matter what.

*EDIT… did’t see your other post where you figured it out… 🙂

if you open a project in RGB you get the PR4X4 MXF option

I would recommend a direct import of ProRes media into ProRes MXF. This is Mac-only and MC 6.0 or higher. This should Fast Import if settings match. However, set all render settings to DNxHD. There are some issues when mixing ProRes and DNxHD using “same as source” exports, mainly when the first clip in the timeline is ProRes. Alternatively, use AMA to link to the ProRes files, boil down your selects and then transcode these to DNxHD for cutting.

Working a lot with ProRes on 6.01, I feel that prores MXF is quite stable and relatively fast, but rendering effects and exporting is a little slower than DNxHD.

I just happened upon this thread and have the same question and worry as Toke. The plan is to get prores(hq) from the on-set DIT and use those to cut in MC6. This will be a feature film about 100 minutes or so and need to make sure that AVID MC6 can handle the prorest mxf files and is stable when editing long form. In the 2 weeks since this thread opened has anyone gathered any further info or work experience regarding this? Toke, how has your experience been?
Thanks

Sorry we chose to go with native dnxhd encoded files… I was not comfotable with the prores files in avid…

[White Yufeng]

DNxHD is the native editing frmat for Avid, if you transcode video to it, you will can directly import it to AVID wothout AMA plugin.

Okay, a few months have passed… anyone else have experience with MXF-wrapped ProRes, especially in long form?

My producers wants the DIT to create only ProResLT QTs (shooting on Alexa in ProRes444LogC) that will be used for editing and for crew to view dailies. This need to be uploaded to an FTP so one flavor keeps things streamlined.

So first question- any problems in longform with the ProRes MXF? Renders in DNx? Quicktime exports (same-as-source issue?) EDLs? Linking back to the original Alexa files (ALEs should be provided).

Then, my assistant and I are in different cities so we’ll both be downloading the ProRes LT files and then fast-importing. I want us to both have the same media (same filenames)… so here’s the problem, we’ll have different filenames (random gibberish added to end of QT filename.

Is that the only problem you can foresee?

Thanks

Hey Brian! How goes it man? Your kid in college yet?

I haven’t done the whole workflow, but I do know of one issue…

[Brian Berdan] “Quicktime exports (same-as-source issue?)”

You can only export SAME AS SOURCE if the codec used in the edit is an Avid one. So it won’t work with ProRes. Solution is to Mixdown to DNxHD and then export same as source.

[Brian Berdan] “Linking back to the original Alexa files (ALEs should be provided).”

Linking back in Avid? Or in something like Resolve? You can’t link to the original files in Avid unless you AMA the original in the Avid originally.

But I’ll let more experienced people answer that and the other stuff. I just know that first answer for sure. And I wanted to say hi.

(I apprenticed for Brian YEARS ago…)

Hey Shane,
Good to hear from you… son is not in college (but soon and I can’t wait!).

The killer issue is my assistant and I not having the same media filenames, so I’ll force production to create DNx, but I liked the idea of this… Tower of Babel, I”m sick of formats 🙂

Cheers

Brian

Oh, what if the DIT created DNx quicktimes for viewing dailies and editing… is there a way for my assistant and I to get those into the our separate Avids with the same filenames? I would think it would still be just a fast import in order to rewrap and I’d still have the same problem.
