This movie will discuss how to output final images from your composite. The time has come to output our final images or sequence from our node tree. But how? First, insert at least one File Out node into the node tree where you want to render. Generally speaking, our File Out nodes fall at the bottom of our node tree because that's the "end of the line" for the composite. All of our work is done upstream from it in the node tree. But File Out nodes can be placed in multiple places along your node tree and the output files can be saved to different folders and formats on your drive simultaneously. This is useful, for instance, if you're saving out files for film output but want to preview them at video resolution before sending them out to a lab. Adding a File Out node is pretty easy. First, go to the globals tab and make sure your global parameters, the duration of your composite, your motion blur settings, frames per second, etcetera, are set to the needs of your project. Then select the node that you wish to render and go to the Image tab, and select File Out. I'm going to add another File Out so I shift click File Out. This launches the file browser where you can specify where to save it and what type to save it as. Generally speaking, if you're saving out an image sequence, you would give it the name, so I'm going to call this Elephant, dot, a number of number signs, 1, 2, 3, 4, that's if I'm not going to go beyond 10,000 frames, dot, and then the type of file that it's going to be if it's a sequence file, such as TIF. If I were to render out a QuickTime movie, it would simply be Elephant.MOV or Elephant.AVI if it's an AVI file. OK, so this time I'm going to use number, number, number, number, dot, TIF as my extension. Then, go to the parameters box for the File Out node and make sure that everything is how you want it there. So, here's my new File Out, and here are my parameters, we'll have to expand this. the first parameter is your image name, which shows the path and file name of your output. The file format defaults to .IFF, so you want to specify it here. I'm going to specify TIFF, T-I-F-F. QuickTime parameters - if you chose QuickTime as your Codec, then the QuickTime parameter Codec options shows up here, but we're doing TIFFs, so my Codec, I want to have no compression on my TIFFs, so I chose none, and my byte order, I'm choosing native. If I were to choose QuickTime, I would change this to file format - QuickTime, click on my Codec options, and change my compression type here. Then you would save the script by hitting Command S or going to File, Save Script. Why is this? Well, rendering a File Out node can be a very processor intensive process and we don't want to jump in and start rendering before we've saved out our script. The next step is to render, so first go to the Render option up here and choose Render File Out nodes. And here you can choose whether you're rendering all nodes or just the File Out nodes that are selected. You can update from the globals by clicking the Update Now button, of if it's grey like this and says Update Now, don't click it, go ahead and change the time range to override your global parameters. Click Auto to automatically load the frame range from the previous node. You can set the quality, which is your anti-aliasing quality, set motion blur settings that will override the motion blur settings that are already there, and Max Thread refers to the number of processors. Now, sequential, this is something new. This is for when you want File Outs to be rendered one at a time. Like for instance, the QuickTime file out first, then all of the TIFFs, then all of the SGI images. The default is off, or non sequential, and this means that all of the frame 1's will be rendered, then all of the frame 2's, so that each File Out is at approximately the same stage of completion. I prefer to turn this on if I'm rendering out more than one File Out node. Then you would hit the render button and wait. Now at the same time as your images are being written to disk, a 320 pixel by 243 pixel snapshot of the current frame is shown. This size is always the same, regardless of the size of your final images and only shows the frame being rendered at the current time. The File Out node is the only way to render final output images from your composite. It's important to understand the difference between the flipbook, which is here, and the File Out node, which is found under the Image File Out tab because the flipbook just creates a temporary preview file as is this, while the File Out is the same as a file export or render function when you're using other editing or effect software.
