RedRocket is indeed an acceleration card and RocketCine-X will not work without it.
RedAlert is a thing of the past, though, Joe. As is RedRushes, and RedCine (non -X).
And RedCine-X is actually both Mac and PC! And its latest builds will create MXF mediafiles directly, without the need to import into Avid anymore. RedCine-X is the application that is meant to replace any and all older incarnations of Red software.
RedCine-X works very similar to RocketCine-X. You can open clips into a bin, then export from that bin after creating an export setting. The most recent builds of both the Mac and the PC version allow you to create Avid MXF files immediately (like MetaFuze does). But you can also choose to export as Quicktime. As long as the Avid codecs are installed (avid.com/codec), that should provide you with the option to convert to QT’s that may be fast imported (you’d need to also generate an ALE somehow, though, otherwise you won’t have tape ID’s).
Indeed, MetaFuze is PC only.
If your footage was shot with the latest version of the Red camera (with the Mysterium sensor), note that MetaFuze will not correctly convert the colors for that. RedCine-X does.
RedCine-X is early beta, according to Red. This means that there may be some issues/bugs/annoyances. A lot of support info can be found on the Reduser.net boards.
Important to know is how to set the debayer options. It may be tempting to select Full Premium, but without a Rocket card installed, that is going to take forever.
The speed of your machine and drives matter much. R3D decoding is a pretty processor intensive task.
