The Image Viewer

The image viewer shows the image of the currently selected shot or the library slot.

When an HD-SDI output device is configured, the HD-SDI output of that device always shows the same image as the image viewer.

You can set the image viewer to fullscreen on the screen where the viewer is currently shown by clicking the green little icon in the window header bar, or click “Fullscreen” in Livegrade Pro’s toolbar.

In a setup with two computer screens attached to your Mac (or a notebook screen with an additional external monitor) the viewer can go fullscreen on one computer screen, while the Livegrade Pro main window is shown on the other screen. To do so, move the image viewer window to the second screen and then go to fullscreen.

The image viewer can display a second image or look (e.g. from a framegrab or a movie of a shot) for reference in a split-screen or overlay mode.


Image Overlay:

The image overlay displays the display options for switching between “Graded”, “Bypass”, and “Original” image. These controls double the controls from the slot user interface.

The image overlay also offers a “Export image” button. This button saves the current image in the file system of your Mac. This control doubles the control from the slot user interface.

Reference Overlay:

The reference overlay shows the name of the image shown for reference, and allows to remove the reference.

Reference Options

In the reference options you can choose which compositing mode should be used for displaying the reference image with the viewers image.

Options are

  • Left – Right: Side-by-side with movable image splitter, viewer image is left, reference image is on the right.
  • Overlay: Reference image is composited over the viewer image with variable opacity.
  • Show / hide the reference
  • Flip (mirror vertically) and flop (mirror horizontally) the reference image for improved arrangement

Image Splitter:

You can move the image splitter (e.g. shown in “Left – Right” mode) by dragging it.

Image Information:

The header of the image viewer displays the current slot name, the name of the image and the name of the reference image.

Playback Controls:

The playback controls provide buttons for play, next frame, previous frame and go to start/end of the movie.

A timeline slider indicates the current position and allows scrubbing to a specific position. Playback can also be controlled using the keyboard shortcuts J, K and L:

  • Playback: Press L to play forward, K to stop and J to play reverse 
  • Shuttle: Pressing the keys L or J two or multiple times increases the playback speed by factors 2x up to 64x
  • Jog: Holding K and pressing L or J allows users to frame-step through a clip forwards (L) and backwards (J)

Other shortcuts for navigation in movies are available from the main menu.

JKL keyboard navigation works for all movies loaded in slots, either in the viewer window or via SDI connected monitoring devices.

A “Loop” checkbox lets you enable/disable loop playback.

Jump To Timecode:

The player HUD displays the timecode for recordings and imported movies. There is an arrow button on the right hand side of the timecode display. Pressing the arrow button opens the “Jump to Timecode or Time” sheet with two tabs “Timecode” (displays current timecode) and “Time” (displays current clip runtime calculated from starting timecode 00:00:00:00).

“Jump to Timecode or Time” sheet

  • Copied timecode references can be pasted in various formats, e.g. “05:57:45:12” or “05:57:45;12” or “05574512”. Pressing Enter moves the playback position to the desired frame in the video.
  • In the “Timecode” tab you can type in a timecode in the format “HH:MM:SS:FF” (e.g. “10012212” = TC “10:01:22:12”). If you enter less than 8 digits, the timecode will automatically fill in the first timecode digits of the current movie, e.g. if the video has a starting timecode of “10:00:00:00” and you enter “2315″ the playback position jumps to TC “10:01:23:15”. 
  • In the “Time” tab you can enter the clip runtime, you want to move the playback position to. The clip runtime is always calculated from starting timecode 00:00:00:00, so that entering e.g. “0124” moves the playback position to the clip runtime 1 second, 24 frames.

“Jump to Timecode or Time…” can also be accessed via the “Edit” menu.

Set Thumbnail Frame and Jump To Thumbnail Frame:

There are buttons for “Set Thumbnail Frame” and “Jump To Thumbnail Frame” in the player HUD. A little marker icon in the time slider indicates the current position of the thumbnail frame. “Set Thumbnail Frame” changes the thumbnail for the shot in the shot library. “Jump To Thumbnail Frame” moves the playhead to the current position of the thumbnail frame.
