From the course: Nuke Essential Training (2014)

The integrated flipbook

- Gone is the old FrameCycler. Nuke 9 offers a brand new, completely integrated Flipbook viewer that it shares with Nuke Studio. It's far less complicated than the old FrameCycler, and offers great real-time playback. To see how it works, we'll start with a little animation that we have here and we come over here to the Flipbook control button, click on that, and it opens the Flipbook dialog box. First thing you'll want to take a look at is where it'll get the settings from and you pop this up. If you've got more than one viewer, you can select that here. If you want to choose some channels, RGBA will get you all four channels. Maybe you want RGB or just the Alpha, or some other channels. Select that there. Now the frame range is set from 30-60. That's because I'm looking at viewer one and you can see I have some in and out points at 30-60. If I want viewer one but I want the full clip, I'll just pop this up and say give me the global timeline numbers of 1-100. The LUTs down here are the viewer LUTs, the same one that you see up here in the viewer. If there were audio read nodes, they show in this list, and you can pop up and select the one you want to include so you can record audio with your Flipbooks now. Okay, we're ready to go. Click Okay and we get our Progress bar and it quickly computes our Flipbook. As soon as it's done it opens the Flipbook and plays the Flipbook for you. So let's take a look at the new Flipbook controls. Up here at the top we have all of the same controls that we have on the standard viewer and they work in exactly the same way. We also have our viewer gain, our Gamma. Reset that, and there's also an audio volume slider here. Now here's an interesting difference between the Flipbook viewer and the regular viewer. The eyedrop icon for showing color samples is by default turned off in the Flipbook, so if I turn that on, it opens up the RGB values down here and we can turn that back off. Down here in the bottom row, this first field is going to show you the playback rate which will be identical to whatever you set in the timeline. You can also change the timeline format. You can go to Timecode now if you want, or back to our frame setting. Now here's another interesting difference between the Flipbook viewer and the regular viewer: I'm going to set some in and out points here - let's say 30-70, and look what it does. It's expanded the timeline to fill the entire viewer. Also above it, you have this little guy right here, which is showing you what portion of the whole timeline you're seeing. And if you click and drag on it, you can actually shuttle through, all the while maintaining the exact same frame length of 70 frames. To reset it, just do a little mouse click up here, and you're back to your normal timeline. Turn off the in and out points, and you see the full timeline again. Now there is a little interesting behavioral anomaly I might call your attention to. If we jump to the first frame with this button here, we land on frame 0, which is black. So to see the first frame of your playback, you have to step forward to frame 1. I'll just click the red button here to close the Flipbook viewer. Nuke 9's new Flipbook is fast, well-equipped, easy to use and perfectly integrated into the Nuke and the Nuke Studio workflows.
