Using Track Mattes with RED RD3 Conforms
Hi guys,
The use of external track mattes is worth the price of admission alone in my humble opinion. To be able to leverage Mocha and After Effects for clean tight mattes used in Resolve is a revolution.We are experiencing two stumbling blocks and are wondering if we are overlooking a simple solution?
One is in regards to all conforms and the second RED RD3 specific.One:
Media imported in resolve and diced with the scene detector make it simple to generate tracking mattes since the specific clip can be exported from the Resolve timeline and used as a source in other applications with which to generate a mask/matte. Upon importing the matte clip it is the same duration and has the same in and out points of the clip it will matte.
When attempting this with a Resolve project conformed from and EDL how does one generate a track matte for a clip that correspond to the EDL’s in and out points and duration for this shot? A track mattes first frame upon import appears to default to 0 and thus never aligns. Is there any way around this other than rendering out the entire master clip that the shot is based on to then use in some cases a few frames for the actual matte required? Some of these clips can be up to 8 minutes long!! If so, since there is no ‘reveal in finder’ method in resolve how does one elegantly find the corresponding file on ones system to use as a track matte source?Two:
Above obviously applies to projects conformed to RD3 files with the added issue of frame sizing. Does one generate the track matte at 4K resolution and size and leave scaling to Resolve depending on the projects ‘input scaling’ and ‘zoom’ attribute on the timeline?All thoughts most appreciated.
Cheers

1. When using EDLs, can you use the Split and Add into Media Pool to shorten the master session clips so it’s easier to render out clips for matte generation?
2. If you are finishing at 2K, it might be better to get 2K mattes to save on some disk bandwidth, CPU, memory, etc.

Thank you Rohit, Most appreciate your thoughts.
Shall investigate ‘split and add’ although it may inhibit re-editing the session depending on what ‘split’ means.
In regards to 2K mattes. We typically work in Half Premium and then switch to Full (4K) for render. I wonder if resolve would compensate automatically for a 2k matte?Cheers,
J
