I’m setting up on Rhino and Grasshopper an animation.
I need the animation being long 4’30’’ with 30fps.
If I go to Render Tool > Animation Tool > Set up 360 degree turntable animation
I’ve got this.
How can I correctly setup an animation if my modifications in GH are taking the real time (4’39’’) but I cannot control the time in Rhino? I know that in total I should create 7740 frames (4’30’’ are 258s*30 frames) but how to coordinate with real time?
This is basically what I’m doing. I’m using Firefly’s Sound Capture to get the data of a song inside GH and do this kind of sculpture. As you can hear, still the last problem is connecting the speaker output to the microphone input (right now the script is “hearing”, through the microphone, my phone playing music but the sound is not pure, there is a lot of background noise).
What I would like to do is to avoid screenrecording and having the renders of the perspective view. In total I would like to have (30 fps) * (length of the song) renders/screenshots which after I take and create a video lenght = length of the song and add the song.
The turntable animation is great but it’s impossible (?) to coordinate the renders (30fps) with the real legth of the song.
Is it clearer? It’s tough to explain it sorry
Could be resumed in: how to create a video (with turntable animation better) of something moving in GH without screenrecording.
Yes @wim but with animate slider you would have 2 problems:
In the meanwhile is working the script of animate slider, turntable animation is not available. But this is the minor problem
Main problem is: how to control the speed of the slider? I did a quick check. A slider 0-10 with 100 frames count is doing 100 frames in 10 seconds, 10 fps. So I’ve set the slider to 0-250 (250s is 4’30’’) and the frame count at 7500 (250s*30fps), but in 250s (the length of the song) I’ve only got 1395 frames created.
You can accomplish “turntable animation” by rotating the entire model where the slider range is 0 to 360 degrees (or 0 to 2Pi radians).
Speed is irrelevant when the animated slider generates a series of still images. How you display those images is up to you. Animated .gif is one way, here is another that offers a choice of ‘Position’ or ‘Delay’: anim6: Spring Equinox, March, 2016
You can pre-record your firefly data to a list using “data recorder” and then extract values from that list when animating through a grasshopper slider. Grasshopper will have different compute times per frame so relying on “100 frames in 10 seconds” type logic isn’t going to work.
You can also rotate your model or camera through grasshopper to achieve a similar look to turntable.
ah yes, nice… rotating the model can solve this. Thanks!
Eh not really @Joseph_Oster because if I want to create the animation with Premiere I need to know the proportions frame per seconds. Moreover I need to be sure that I’m in syncro with the music
Yes you are right. My problem is that the still images have to be in time with the song… so that’s why I need the fps I think.
If you think I’m not correct and you want to show me how to have data, still images and music in syncro please show me, I would be glad to have this kind of help Thanks!
Make the animation with enough FPS and then in your video editor change its speed and position to match the song pulses. If you increase the speed and it’s jumpy, you need more FPS.
The length of the audio clip times the video frame rate you want tells you the number of images you need from Rhino, which is the number of divisions to apply to the rotation slider.
I’ll test it today and I’ll let you know.
Thanks!
