Bad scrolling text animation

t00r0p's icon

Hello everyone,
I'm trying to animate some text with jit.anime.drive and the result is very poor.
Is the scene the same for you : unreadable text because of some trembling mouvement ?

Do you have a solution ?
Thanks by advance...

You have to be careful regarding to timing issues (vsync of your monitor vs qmetro timing vs line objects rate, etc).

Suggestions: use jit.world instead of jit.render/jit.window
Connect a jit.gl.material to your objects instead of using "old" strategies like @lighting 1 and other legacy OpenGL approaches
use bline instead of line
derive what you can from a main "metro" (in this case, jit.world)
Be careful with triggering output (automatic 1) without needing to output/process.

Good luck!

Thanks for your reply.
The "sync 1" and "fps 60" (refresh rate of my monitor) don't seem to change anything.

Ok, even After Effect 60fps can't make it smooth enough... I'm discovering wonderfull things on vsync... :(

Yes, if you want smoother animation you would neeed to use techniques such as motion blur, be it in After Effects or Jitter.
