Output looks sped-up when duration is higher #56

Open hsilvaga opened 4 months ago

hsilvaga commented 4 months ago

I'm noticing that the outputs look normal when the duration is set to 50 frames. But it looks sped-up when the duration is set to 300 or really anything higher than the original 50. It almost looks like its running at ~2-second intervals by default.

I'm wondering if I'm missing some sort of parameter which is affecting the playback speed?

we have 0.0125 /2 as the default interval. although you can adjust interval to any float number with _playspeed . _playspeed can be any float number.

Following prior work hypereel, hyperparameter is for 50 frames duration.

I plan to update viewer for multiple 50-duration models. stay tuned for that in the next four weeks.

Seems like its a viewer-side parameter. Thank you!

apology for the delay. i have too many things to do. mutlivew viewer is still on the todolist. stay tuned !
