Rendering menu > RAM Player
The RAM Player loads a frame sequence into RAM and plays it back at selected frame rates. The RAM Player has a channel A and a channel B. Two different sequences can be loaded into the channels to play back together, giving you the ability to compare them.
Clicking and dragging in the channel display window allows you to set the A/B divider between the two channels. The right mouse button “scrubs” the animation through all of its frames. Hold the right mouse button and move the mouse left to move the animation back to the first frame. Move the mouse right to advance the animation to its end.
For best RAM Player performance, Gamma should not be enabled in Customize > Preferences > Gamma.

Open Channel—Displays the Open File dialog that lets you select a file to load into the channel. After you have selected a file, the RAM Player Configuration dialog appears that allows you to set height, width, and memory usage for that channel.
Open Last Rendered Image—Loads the last rendered image into the channel. Nothing is displayed if there is no last rendered image available.
Close Channel—Unloads the image in the channel and frees up your memory.
Save Channel—Displays the Save File dialog that lets you save the animation or image from the respective channel. You can save the animation as a .avi file or a numbered sequence of images.
Note: The RAM Players converts everything it loads into 24-bit RGB which means that some information may be lost when it is loaded. This may affect a file saved in the RAM Player.
Channel A—When selected, this button will show the file loaded into channel A. Split screen markers are displayed if both channels are enabled. The split screen markers are represented by two triangles. These markers indicate where channel A ends and channel B begins. You can move the divider using the left mouse button.
Channel B—When selected, this button will show the file loaded into channel B. Split screen markers are displayed if both channels are enabled. The split screen markers are represented by two triangles. These markers indicate where channel A ends and channel B begins. You can move the divider using the left mouse button.
Horizontal/Vertical Split Screen—Toggles between the view of the two channels side-by-side or one on top of the other.
First Frame—Automatically returns the RAM Player to the first frame of the animation. If the RAM Player is at the first frame, First Frame returns the animation to the last frame.
Previous Frame—Backs up the RAM Player to the previous frame in the animation. If the RAM Player is at the last frame, Previous Frame returns the animation to the first frame.
Playback Reverse—Plays the frames in the animation in reverse order. The flyout contains an option to play the animation once and then stop.
Playback Forward—Plays the frames in the animation in rendered order. The flyout contains an option to play the animation once and then stop.
Next Frame—Advances the RAM Player to the next frame in the animation.
Last Frame—Automatically places the RAM Player at the last frame of the animation.
Frame Rate Control—Sets the desired frame rate in frames per second. When playing back a movie, you see the frame rate displayed in the title bar of the RAM Player. You can select a predefined frame rate or type in your own frame rate value.
Color Selector—CTRL+right-clicking the mouse in the display window displays the color of the pixel in the color selector swatch. Stop the animation to get a correct pixel reading. The RGB of the pixel is also displayed in the title bar of the RAM player.
Double Buffer—Selecting Double Buffer ensures that the two frames in channels A and B are syncronized. Enabling this function has a substantial impact on the maximum frame rate.
