CS5: replacing footage lagging – R3D to PRORES
Hello
I am working in Premiere Pro CS5 on a Macbook Pro. I’ve edited a sequence & footage directly with R3D footage, but now I am trying to replace all the footage with PRORES footage that i’ve exported from the original R3D footage using REDCINE-X (Build 454)
The problem is that once I replace the footage (from the Project Window in Premiere Pro), the playback becomes extremely laggy, if there is any playback at all. I scrub the timeline with the replaced footage, and it takes 20-30 seconds before the preview window updates.
Has anyone else encountered this kind of problem? I made the mistake of editing with the R3D footage, I should have exported directly to PRORES to begin with, I’ve never had problems editing with PRORES footage before.
If you’d like more information like my project specs, let me know. Any help and insight is welcomed.
Thanks in advance!

At first glance this doesnt make a lot of sense. You are saying that you edited R3D footage (which is either 2k or 4k in size) and had no problem.
And you are replacing it with Prores (1920 x 1080 -but which version) which could be at least 4 times smaller than the files you originally cut, and you now have lag.
I would close the project and delete both caches (data and media) . That might help. Im guessing you are editing from a high speed external array or else you would have had problems with the R3D media. Usually by right clicking in the right Program Monitor screen you can drop from full resolution to aid playback as well. It certainly is a curious situation.Tom Daigon

Hello
I’ve attached screen images with some settings. I’m editing with my footage connected via Firewire-800 on a Lacie 500gb drive, which never caused me problems (in fact it caused me joy, myself coming from a Windows background 🙂
I suppose the export settings in REDCINEX could be too high, but I’ve never had problems with exported footage. Of course I’ve never tried to do “proxy footage” replacement like in this case. And the reason why I am undergoing this footage replacement task is because I only realised after I finished editing that the source R3D footage would not be easy to color correct – or key out the green in this case – because they were not using the right color profile.
I tried flushing video cache, but it doesn’t seem to do the trick, even though the cache is below 100mb anyway. I also have no problems with playback when the exported Quicktime Prores 422 footage is running with Quicktime Player.
Thanks again

so a small update:
As a test, I created a new Premiere Pro project and dropped all my exported PRORES422 footage into the timeline, and it runs perfectly fine, silky smooth. So this situation is particularly odd.
At this point I have 2 options:
– continue swapping my R3D footage with the PRORES footage and deal with the lag
– or re-edit my sequence from scratch, manually replacing the footage in the process of remaking the edit.Also interestingly: If I do the reverse – ie. replacing PRORES footage with R3D footage – I don’t seem to have any lagging problems, at least with the small test I did.
I didn’t think the “Replace Footage” command would be so painful, oh wells..

Try creating a new sequence with settings to match your ProRes clips. Then copy the entire contents of your R3D sequence into it, and start replacing your clips. Should work since your new sequence is using Quicktime as the playback mode, not R3D. Hope this helps.

Could this be a case of the relinked media needing to index when you connect it?
guessing….
