LaserBoy !!! / Re: Frame rate for wave export

I'm trying to vectorise video. Still lots of tweaking to be done. An example is attached. (Not great quality for many reasons - it's 48-kHz output as I can't currently do both DC coupled output and 96 kHz.)

Thanks for your reply!


I'm writing the wave at 96 kHz, so at 16fps that's 6000 samples per frame.


Suppose a frame has 5000 points, what I'd like it to do is output those points then the first 1000 again, so that the next image can be displayed exactly 1/16 second later. But if LB never writes partial frames then I presume this isn't possible. I can find a workaround for this.


Currently the x menu uses options 1234ahj - I'll look into 789 as you suggest.

I'm confused about how LB renders WAV files. I'm importing a directory of DXF files (with lots of vertices) and have the frame rate at 16 fps. I'd like each image to display for 1/16 second, but after saving the wave file it lasts for rather longer than (numberofframes/16) seconds. I'm doing this with o/3/4 or o/3/8 (and I don't really follow the difference between these).


(I'm aiming to display things on an oscilloscope or vector monitor rather than lasers.)

Clearly I'm missing something - presumably the distinction between a LB frame and a video frame. Can anyone clarify?
