Here is a script that animates a camera from a camera-target position file. It uses ffmpeg for the video creation.

Thanks, can you provide an example of the camera path file, we would need to know the format in order to create the proper file.

The format is realy simple
6 numbers comma sepparated for each frame
ct= camera target
cp= camera position
ct_x,ct_y,ct_z,cp_x,cp_y,cp_z
this is 10 frames below

Getting error

Code: Select all

Expecting a 3-component vector

so it appears there may be an issue with the formatting

Also note that ffmpeg.exe is required but not included http://www.ffmpeg.org/download.html
Windows build http://ffmpeg.zeranoe.com/builds/

Are you putting the given data in a file and gives you this error ?

for ffmpeg the only till now solution is to be in c:\Program Files\OTOY\OctaneRender\ffmpeg.exe

i will figure later on hoe i can setup the script to find it on its own ...

( do you have the 1.50 standalone version of octane ?)

And time estimation

Using 1.52 standalone will try this new script.
Yes I copied the coordinates portion into a text file without headers.

Ok fixed ...
Thanks

in this version you must put ffmpeg.exe in the lua script directory


..

I think there is a problem with the command line that this script builds and send to ffmpeg, it will not handle file names or directory paths with spaces in them.

Does anyone know what the correct syntax would be to fix this.

many thanks

How do you create the camera path position file?
