Tracker problem and other

[pkruszewski]

Hi , i'm new Nuke user. I migrated from Shake. I tested couple of feature like tracker. I found it's more complex that it should. Here's a problem i got.

1. I have script file (test.nk.zip)  : http://transfer.metamorfo.net/test.nk.zip

pls check it. I created 2 tracker node, named : follow1 and follow2. Tried to switch the value on 'switch node' from 0-1, see the result. the follow1 node is working properly while the follow2 is not. Check that the track-2 of both follow1 and follow2 are exactly the same position at any frame (they overlap along the duration). the only different is the in-between of follow1 has keyframes , while the follow2 doesn't (keyframe only at frame 1 and frame 20). Using follow2 , you can see the result for example at frame 10, it's OUT OF TRACK than it should. i believe they do the internal calculation differently between these 2 nodes, but can i consider it as a BUG?? any one can explain this? I tested using shake and no problem at all.

1. Flipbook In shake i can do this but in Nuke why can't i just cancel the flipbook process at any frame and still can preview the result (i should be able to view the frames has been rendered so far). so i don't have to wait till the flipbook is finished.

2. Flipbook again. Also when doing flipbook or rendering , it would be nice if there's an option to view the frame being rendered on the fly. it might slow the system but it won't hurt if i have that as an option. So i can see every single frame being processed, in this case i can see if there's any problem with my compositing again without have to wait until the whole selected frame is finished.

3. Simple thing i couldn't find. Using the framerange node or retime node... It would be very very handy if there's a 'use current frame' button - so i don't have to type the frame number. Just click the button and it will use any current frame as the value. It saves time.

4. i couldn't find this.... Does nuke have multilayer merge? so i don't have to use multiple 'merge' nodes for multiple layer.

Thanx Andi

Since I'm at work I can't currently view your script so I can't really answer the first question.

question 2: To be honest, I never use the flipbook feature since frame cycler isn't very reliable (in my experiences), however, I do believe that nuke has a temp dir in which flipbookframes are stored. So if you cancel your flipbook render you should be able to find the rendered frames there and open them manually.

As for question 5: This is possible through some merge operation such as plus or max, when 2 nodes are connected to the merge node, a new arrow will appear on the left side of the merge node. Through this pipe you can connect additional inputs. Although, if you want to use different blending modes you're gonna have to use multiple merge nodes I'm afraid.

Hope it helps!
