Chapter 23: Rendering a Scene and Enabling Quicksilver



                           The Open Last Rendered Image button in the RAM Player interface window provides quick access to the
                           last rendered image. The Close Channel button clears the channel. The Save Channel button opens a file
                           dialog box for saving the current file.

                   Caution
                   All files that load into the RAM Player are converted to 24-bit images. n
                           The Channel A and Channel B (toggle) buttons enable either channel or both. The Horizontal/Vertical
                           Screen Split button switches the dividing line between the two channels to a horizontal or vertical line.
                           When the images are aligned one on top of the other, two small triangles mark where one channel leaves off
                           and the other begins. You can drag these triangles to alter the space for each channel.
                           The frame controls let you move between the frames. You can move to the first, previous, next, or last frame
                           and play the animation forward or in reverse. The drop-down list to the right of the frame controls displays
                           the current frame rate setting.
                           You can capture the color of any pixel in the image by holding down the Ctrl key while clicking the image
                           with the right mouse button. This puts the selected color in the color swatch. The RGB value for this pixel
                           is displayed in the blue title bar.
                           The Double Buffer button synchronizes the frames of the two channels.
                   Tip
                   You can use the arrow keys and Page Up and Page Down keys to move through the frames of the animation. The
                   A and B keys are used to enable the two channels. n

                           Tutorial: Using the RAM Player to combine rendered images into a video file
                           Not only can the RAM Player be used to load and compare images, but also it can handle animation files. It
                           also can load in multiple frames of an animation that were saved as individual image files and save them
                           back out as an animated file.
                           To combine multiple rendered image files into a video file using the RAM Player, follow these steps:
                               1. Select the Rendering ➪ RAM Player menu command to open the RAM Player. Then click on the
                                  Open Channel A button and locate the Exploding Planet - frame 10.tif file from the Chap 23
                                  directory on the DVD.
                                  This file is the first rendered frame of a ten-frame animation.
                               2. The Image File List Control dialog box opens. Using this dialog box, you can specify the Start and
                                  End Frames to load. You also can select to load every nth frame. Select 0 as the Start Frame and 9
                                  as the End Frame and click OK.
                               3. The RAM Player Configuration dialog box loads next, letting you set the Resolution and Memory
                                  Usage for the loaded files. Click OK to accept the default values.
                                  All of the image files that share the same base name as the selected file are loaded into the RAM
                                  Player sequentially. Press the Play button to see the loaded animation.
                               4. Click on the Save Channel A button to access the file dialog box, where you can save the loaded
                                  animation using the AVI, MPEG, or MOV video formats.
                           Figure 23.11 shows one frame of the loaded animation files.
