Thanks juan for the tips. im really new here. [flash=420,340:3s60yqdk]http://www.youtube.com/v/G0NU_nxLLpY&hl=en_US&fs=1&[/flash:3s60yqdk] Im render using plugin for sketchup called "skIndigo". Latest plugin have option to Export Scene Tab Animation. i choose 10 fps for the render ( since this is for test scene only ), then combine all together using picasa movie maker ( u also can use Qtime ) as time lapse and save as 24 fps. Thats why u see the video is speedup but smooth. p/s: sorry my english. im from Malaysia.
