For future reference, here is what fixed the problem:

We are using 4K, and have made proxies using ProRes Proxy. One of the first things I did to troubleshoot the lag issues was verify that the proxies were attached. BUT what I did not know is that there is a setting under Preferences > Media that says “Enable Proxies.” If this is not checked, even though the proxies are attached, they will not be used.

Two calls to Adobe support, multiple forum posts and searches, and this never came up. LOL.

It’s working perfectly now.

Wish there was some indication in the timeline, or elsewhere, showing which media you are actually using!

Thanks Vince,
I forgot to mention I’m using a Glyph Technologies 4TB Studio S4000 External Drive, which has a spin speed of 7200rpm. We have this project on several other computers – mac TrashCans – and of course it runs very well there.

I know my machine is a bit slow for this, but I can’t imagine it should be to the point where I can’t actually work… especially since we’re using Quicktime ProRes proxies.

any other ideas beyond insignificant computer power?

thanks!

Michael, thank you so much for your help! I see your replies all over this forum and I really appreciate all the time and knowledge.

I’m sorry I’m still not totally clear on what to do for the full-res footage I’m sending to the VFX house.

I relinked to the camera originals via AMA, and then I set the FrameFlex aspect ratio to be 16:9, and Reformat to Center Crop, and transcoded to ProRes 444 with the compatibility option turned on for reformatting, so it would bake in.

Then I just exported those clips via SaS, since they didn’t have any frameflex moves or whatever done in the timeline, so don’t need rendering, right?

I’m trying to get the VFX people 1920×1080 files with the correct aspect ratio, and as little resolution-loss as possible. Did I do things right for that?

Thanks again for your time and expertise!

For what it’s worth I really think going back to a file renamer is going to save you a lot of time and pain in the long run. On the Mac I really like A Better Finder Rename, which is a paid application but works wonderfully and has loads of options. You can set it up to do multiple steps at a a time, and it is capable of recursing through subfolders, so with a little care you very likely could do most of your files in one go. You can also save “droplets” from it, which would allow you to drag any new folders of images into it for quick processing. Very useful!

So now we need to send some footage to a VFX house. I had expected to do this part later, after doing the online/conform in Resolve, so I’m trying to figure out how to use an offline tool (Avid) to do an online job. Fun fun!

My plan is this:
1. put the clips I need into a single sequence
2. relink to the AMA source
3. use FrameFlex to set the Frame aspect ratio to 16:9, Reformat set to “Center Crop.”
4. change project color space to RGB 709,
5. transcode to Apple ProRes 4444 MXF, use the “Apply reformatting option” box to bake in the crop
6. consolidate sequence with 4 second handles
7. export resulting new clips as Same As Source.

My questions:
A. Will this result in the highest possible resolution that Avid can give me?
B. Is that the best codec to use?
C. Is that the best Frameflex settings for this? They always planned to crop the sides of the image (no idea why they bothered to shoot 2k at all…)
D. Do I need to render my timeline before I export?
E. If there’s some other better way to do this, I would really be very grateful to know it!

Thank you all so much for your time and your expertise!

You might be able to map the remove effect command to the keyboard, then you could select your clips with the direct selection tool, hit Remove Effect, which will work on all the selected clips, and then hit delete.
