Question

Apply a LUT to proxy from R3D

I'm brining in a bunch of R3D's from a Helium sensor and I'm using IPP2 in the source settings. When I apply a LUT in the source settings (RWG_Log3G10 to REC709_BT1886 with NO_CONTRAST and R_4_VerySoft size_33 v1.13.cube), it doesn't render out in the proxies and I have a proxy file with a LOG gamma and a hi res file with REC709. Is there a way for me to bake that into the proxy?

    Correct, the "RED Source Settings" Source Effect is not supported with the Proxy Workflow.

    It's mentioned in the "Known items & tips" section.

     

    The workaround would be to set the RED Source Settings as desired to the RED source clips, then send the RED Source Clips to Adobe Media Encoder and transcode to settings that will work well as a Proxy (like custom QuickTime using ProRes Proxy at a snaller frame size, and then attach the resuling MOV files via right-click > Proxy > Attach Proxies....

     

    When creating Proxy files manually like this, it's especially helpful to follow the following tip from the "Known items & tips" section fo the Premiere Pro user guide:

    • The recommended Proxy workflow includes appending "_Proxy" to the name of your Proxy clips (for example, scene01_Proxy.mxf) and placing Proxy clips (on disk) in a folder named "Proxies" that is placed right next to the Full Res clips. This helps with reattachment of clips. The Create Proxies dialog's default destination setting takes care of both of these conditions. If you happen to set a custom destination, then you should add the Proxies folder to the destination. By default, any Create Proxies action automatically appends "_Proxies" to the clip name.

    So on one of the bins, when I point to the folder with the proxies, it automatically defaults to the MOV's next to each R3D. I don't want to do this, I want to link to the proxies I created but it will only link one file to that path and default to the MOV's next to the R3d forcing me to point each clip individually. I tried various combinations of check boxes but nothing seems to work, I dont want to have to link each clip. Any thoughts?

    It is so frustrating when some rather obvious parts of the normal workflow don't ... flow.

    It's frustrating because RED has been around for long enought that they should be aware of the workflow needs. I still can't get the QT's the camera makes to span the multiple files for use as proxies because of the 2GB file limit (that would eliminate a lot of this problem). Supposedly the camera can do a UDF format rather than a FAT32 that will eliminate the 2GB problem. However most DP's wont be aware of that and will be very reluctant to try something they aren;t familiar with, and rightfully so.
