VectorFrameblend ExampleVector_FrameBlend is essentially just a frameblend node but uses smart vectors to 'stabilize' the input frames to preserve motion detail even with mutiple frames being blended. Internally, the functions of the smartvector and vectordistort nodes are recreated using a vectorgenerator and stmaps to speed up the node and allow up to 11 frames to be blended at once. additional inputs can be used to utilize external vectors or a matte input for use in the internal vectorgenerator node. Hopefully use cases can be found for this node, I have been using it to make another ML tool MiDaS Depth more temporally stable!

Update v1.1:

-Added merge operation option (Thanks Nikolai Wüstemann for the idea!)

-Added channel control (can apply to all input layers)

-Added overscan support and ability to hold first and last frames to avoid artifacts

-Fixed bugs with stmaps introduced in nuke 13

Hey, this is a really great tool and I use it a lot.
For some reason it stopped working after Nuke13. The stmaps are black and if I add any random node before them (like a grade) it gets back working with the viewers, but it doesn't render at all. It only renders if I render one frame at a time

It does not work on nuke 13 because with did something related to how they handle timeoffsets (something with pathProcessing, I think. One of the dev on my last studio had a long chat with them about that, I don't have all the details...).
If you replace the timeoffsets in the node with framehold with a frame+/-1to5 expression if works very well !

Hey Cyril! sorry for the long overdue update, but the nuke 13 + issue is now fixed in the latest version, not sure how the foundry let that nasty stmap bug slip through.....

Hello, you have a beautiful tool, but it creates a problem in version 13 to 15. Please release a version that you put in the Shuffle tree under TimeOffset and it will solve the problem of locking the stmap channel. Thank you.

It is now fixed in v1.1 now! thanks,
