Is there any reason you do not pass middle frame to guider in 2nd stage?

Good question. Been a few since i made that one, but i dont see why not.
Could perhaps be to let the model have a bit of freedom in the final stage, but the middle frame shouldn't be that tricky.

will test a bit here, and see if it was just an oversight or a reason for it

Thanks for fast response.
I built my own workflow, basically also FML frames with guider and custom audio with perfect loop acoustic music audio with 7.660s length to fit into 8 frames tick, with goal to create perfect video loop with middle frame driving movement and FL frames to make guide if you put video on repeat. So far I'm experimenting with guider strength values, I took example from your notes and started with 0.7/0.3/1.0. I tried 30 fps too, for faster movement.
But obvious problem is in short time subject does not have temporal freedom too much, and forced start and end do not help too.

Yes i set the middle frame strength low. It sort of depends on the input image, but since a video is only 5-10 seconds long (usually), the model often struggles to make a natural transition through all the frame inputs if they are set too strong, or it gives some artifacts when it reaches that exact frame. Might also be why i dropped it in the 2nd pass.
But will open it an try it out, maybe there is some sweet spot

And its only 8 steps. I bet that with the Dev model and more steps, you could try more extreme things, and stronger values, since it has more steps to complete a good render
