mocha has always been very popular as a tracking tool, but with the rising interest in stereo 3D conversion, its rotoscoping capabilities have become a favorite player in that pipeline and sales have soared. In this course, Steve Wright covers the basics of operating mocha, as well as advanced tracking and rotoscoping techniques. The course also covers the mocha/Nuke stereo 3D production pipeline in detail.
mocha's Preferences are used to tune it to your workstation and network capacity as well as preset it for the most common types of clips you work on. Here, we'll take a look at the Preferences you're most likely to need. We'll find Preferences here in the mocha, pop-up, Preferences. We have Output Settings, System, Software Update, Clip, Lens, Logging, and, of course, Keyboard Shortcuts. On the Output Settings Tab, here you get to set the Output Directory for your project, and your temporary renders.
The Relative Path is what puts the Results folder in the same directory as your clip. If you want to set the Absolute Path, you can then direct it to any place you want. This will report Disk Space Availability, and if you would like your Cache Temp Directory to go somewhere else, you can stipulate that here. The Cache Original Clip feature: if you're working on a slow network but you have a fast local drive, the Cache Original Clip feature will copy them from the server to your local drive, and help speed up your productivity. Use Textures here means mocha will use your video card for doing playbacks, which will speed things along.
However, some video cards can't handle it, so you would turn that off here if you're having trouble with your video card. Down here is the amount of RAM from your video card that mocha will use for doing playbacks and about 75% of the RAM is what's appropriate here. Next, we will take a look at the System. So by default, Autosave is enabled and if you want to turn that off for some odd reason, there you go! This, of course, defines how many minutes between Autosaves. This is the number of screen layouts you can save and the default is 3.
You can increase that if you wish. Now Rotational Controls, you might remember that we come up here and select gamma, for example, and then twiddle a little circle to increase and decrease the screen gamma. That's what Rotational Controls are. If you want to, you can set up for Linear Controls and then you would click-and-drag sideways. If you want to change the color of your Layers and Splines and control points, you can do that here. This sets the maximum number of undo commands you have. Software Updates simply controls how mocha does the updates.
If you have this box checked, it's automatically going to check in with the Mothership. Otherwise, you can force a check by clicking this button here. The Clip Tab: with this tab you can set up the default configuration for clips that you load in. For example, if you're always doing video, you might set the Frames Per Second to 29.97. If you're only working with Cineon or DPX log files, you can set the Format for Log. If you're always working in video, you can set Timecode here, and if it's always interlaced, you could turn on the separate fields.
Now, the Lens Tab is really used with mocha Pro. It has a Lens distortion feature that you don't have in regular mocha. Logging: this defines the log that mocha creates in case you have a system problem. This button obviously enables it, and down here is the path name and the file name where the Log File goes. You can change that destination right here. Comprehensive saves out a very detailed report, but it does take a little bit of system resources.
So if you're desperate for machine cycles, you could set it for Normal, but then imagine your system will get less information on your bug reports. And the Keyboard Shortcuts Tab lists the shortcuts for each of the various modules. Right now the module is set for Track, but there are different shortcuts when you're in the Clip or in the AdjustTrack modules. So set this for the module you are interested in and look up your Keyboard Shortcut. Okay! That's enough about setting up a project and preferences.
Let's go back to doing some rotoscoping.
