If you can upgrade to the newest MC version, i would recommend it. I’m not sure when it started, but it is pretty easy now to switch your project from 1080 to 4k and back again if you wanted to.
In your situation, you said you have a 4k 29.97 project setup…is your footage at 29.97 or 23.976?
If 23.976, than set your project to that….either 4k or HD…your choice.
If you think there is a chance of a 4k output, then i would link to the footage in 4k and transcode to a lower res for editing.
Keep your original links in their own bins…you will want them later.
At this point you can then switch to HD, or simply monitor HD and edit in 4k, or edit in 4k proxy mode (which is essentially HD)
If at the end of it all they want a 4k master, relink your sequence to the original 4k links and re-transcode your show to high quality footage, or simply create a list from the links and send that list to your color program (Resolve?) along with the original footage. (The online process should be discussed now as well…test your workflow now, not in 3 months)
Yes you can use 4k material in an HD project and have it maintain its original size, but be aware this is also a good way to see that the focus may have been a bit soft during the interview. Sometimes it works great…sometimes you go “hmmm that shot is soft)
When you say your laptop isn’t powerful enough to handle the transcode, what do you mean by that? Is it crashing or just taking a long time? What is your drive setup that you are transcoding to and from…that could be where your bottleneck is occuring.
Consider background transcoding with Avid. For larger jobs i set up the transcodes, exit Avid and let it run all night.
You get a nice view of any clips that may have failed, and you can setup a nice batch that spans several bins, so you can organize your project as you go.
As for transcoding in Resolve and editing in Avid, that is certainly an option, and typically way faster. Test your workflow, before getting carried away. (can resolve relink your timeline out of Avid back to the original files in Resolve)
The AAFs that are created are simply there to bring into avid to help your identify where all your clips are. Of course you have to put your resolve created media into the AvidMediafiles/MXF/ folder structure in write enabled folders, for Avid to be able to use those aafs properly. From there import the aaf into avid and organize your bins.
Can’t speak to a7s footage. Never seen it.
