Nuke 7.0 roto shapes to Nuke 6.0 - 6.3 Hi friends today i faced a problem with nuke roto shapes because of version-up. I done roto with nuke 7.0 and my friend need it for nuke 6.3. I just rendered as image sequence and send it to him. Everything is fine.  But the edit has changed later and frames extended at beginning of the shot. So i searched with google and found a solution. Thank you foundry!!! always artist friendly.. They already have solution for this. They documented this with release notes. You can find this nuke 7.0v1 release notes page no 8. If you want Nuke 7 scripts to load in Nuke 6, use the convertToNuke6 or convertDirectoryToNuke6 Python functions when running Nuke 7 in terminal only mode. Here is the step to convert nuke7 rotoshape to nuke 6 rotoshape. Save your roto-shapes into new nuke file and save it into separate folder. step 01. open terminal and redirect to nuke7 installed DIR. step 02. Run nuke terminal mode. ...

Export Nuke's retime information To 3D packages: This is happen while working with production. In most cases retiming is done beforehand or at the end of a comp. Some time shots getting retimed after Match-move is done. By that time Nuke's retime data (curve) will help to match the tracked camera to new retimed plate. Here is the trick to export nuke's retime date (curve) to 3D packages such as maya, max, Houdini etc. Here im explaining how to export nuke's retime curve to maya. Constant re-speed. I want to retime my input by 200%. Add a retime node and change the speed to 2. Don't forget to change the filter option to None . Retime node doesn't generate retime curve at all. So note down the output range. It changed from original range 1001 - 1042 to 1001 - 1021. Which means our input ended with 1021. Add a TimeWarp node and set keyFrames based on our retime output result. Set a key frame at 1001 as 1001 in input frame knob. Got...

merging multiple camera projections While working with some clean-plate  or clean-up work. Usually we create multiple peace off patches and project those peaces onto the "cards" ( usually ), sometime on some geometry. like below image:   Here i projected on 3 cards for getting this result. I red on fxguide forum, some one asked like this, is there any way to merge multiple camera projection? http://www.fxguide.com/forums/showthread.php?11757-merging-multiple-camera-projections Here is the example image which is he attached. Its look really complicated when its grow with some other patches. Here is solution for this. "MergeMat" will do the magic. Add a mergemat node and merge the two projection node output. Add a card node and connect it with mergemat node . Here is other example. I projected 3 images on a cube by left, right and front side with 3 different cameras. Using "M...

stereoDaily.gizmo stereo daily.: Here i'm sharing my latest gizmo for creating daily's for stereo production. StereoDaily gizmo contain three types off  write nodes (Anaglyph, Nvidia 3D vision and 3D tv's).  Its grab file name from your input and add it to the mov with frame no. (like below image) Your file naming convention need to be like below..  ( Project_Reel01_SH_01_v01.l.0001.dpx) or ( Project_Reel01_SH_01_v01.left.0001.dpx) Don't use underscore after version no.. ( Project_Reel01_SH_01_v01_left.0001.dpx) You can change your daily's path as per your wish by update the Daily node path. StereoDaily gizmo automatically create folder structure based on your system date and stores the .mov files on to the daily's folder. Like below image..  G:\Dailys\01_SBS\21-05-2012\Project_Reel01_SH_01_v01.l.0001.mov  I used  photojpeg codec for SBS, Anaglyph and H264 for 3D TV. Add stereoDaily gizmo and import your left, right view file...
