@lhepner, it's possible to output video as an image sequence with the Save Image node. Here are a couple of examples.

Option 1: save-image-sequence.vuo — Saves an image sequence in realtime. Since it's realtime it might drop frames.

Option 2: convert-movie-to-image-sequence.vuo — First use Vuo's File > Export > Movie, then run it through this composition which will extract the movie's frames to an image sequence.

(Both compositions save the images to the same folder as the composition.)

@jstrecker commented on @cremaschi's Feature Request, “"make transform list" inversion

Not that I know of. It could be done if there were an Invert Transform node (matrix inverse) and a Transform Point node (applies a transform to a point, and outputs the transformed point). Converted your question to a feature request, opened for voting.

Hint to anyone who might want to implement these nodes yourself: There are already functions to invert a matrix and transform a point in type/VuoTransform.h.

@jstrecker commented on @loddie's Discussion, “Simple Video Delay

If your computer has enough VRAM, and if your Blackmagic device supports it, you could accomplish this using the attached Vuo composition. It stores up the video frames as they come in, then starts passing them along to output after a delay.

7 seconds of stored video frames at 1080p is about 3.5 GB. You'd probably want a system with twice that to be safe (leaving room for Vuo's input and output buffers, and system buffers). The high-end Mac Pro only has 6 GB of VRAM; the baseline iMac Pro has 8 GB of VRAM, so I'd recommend the latter.

Does the Blackmagic Intensity Pro 4K support full-duplex (simultaneous input and output)? If not, you'd need to replace the Send Blackmagic Video node with a Render Image to Window node to play back on the computer.

Ideally Vuo would preserve the title exactly as you typed it. The title and node class name could be edited independently, rather than one determining the other.

@jstrecker commented on @krezrock's Discussion, “Get Mesh Values Node / Scale

mic (@cremaschi), are you sure that Get Mesh Values is the problem? And you have the latest version of co.parabox.nodes.vuonode? I was able to run a small composition containing Get Mesh Values in Vuo 1.2.7.
