Keyframe Display Issue

Anonymous — Thu, 25 Feb 2021 11:48:37 GMT

Hi, How do I make the keyframes to show on the actual frame? It seems they are all over the place, I need them placed exactly on the the number, now it shows as if there are in between half frames etc which makes it very difficult to move or select. Do I need to change something in the settings? Please advice.

Also to mention that the issue originates from the fact that somewhere along the project I accidentally converted the scene from 24fps to 30fps without keeping the frames at position, and now I have all these in between frames which I cannot control and its very frustrating. Is there a way to get the frames back to normal, please help. Thank You

What comes to mind is either you move all the keyframes in the GraphEditor/DopeSheet sideways forth-back with the TimeSnap option enabled, and correct some keys that jumped to the same frame (the animation slightly alters ) OR do Edit>Keys>Bake Simulation (you'll have the same animation with bunch of keys and those decimal frame keys, which you can partially fix with SmartBake). Both ways involve the manual intervention.

Hi and thank you for your reply, what you proposed works but as you said will require manual work, I found this script which I think does the job as it moves the keyframes to whole frames.

{ // get all selected anim curves or anim curves attached to the selection string $animCurves[] = `keyframe -q -name`; for ($animCurve in $animCurves) // browse them { // get all selected keys at this curve float $thisKeys[] = `keyframe -q -sl $animCurve`; if (!size($thisKeys)) // if no keys selected get all keys $thisKeys = `keyframe -q $animCurve`; for ($keys in $thisKeys) // browse the keys { if (`fmod $keys 1` != 0) // if the keys have decimal places move them to the rounded keytime keyframe -e -t $keys -iub true -a -o over -timeChange (floor($keys)) $animCurve; } } }

Ok, as I read from code, it moves all keys backwards, even those that are .99, so you will have a slight animation change. It is the same as I described in the first method, you still need to select animcurves.

Later today I might rewrite this script so it moves keys to the nearest frame.

This makes the key approximation more precise.

// The script rounds the key times of selected curves/keys to a nearest integer frame. // get all selected anim curves or anim curves attached to the selection string $animCurves[] = `keyframe -q -name`; for ($animCurve in $animCurves) // browse them { // get all selected keys at this curve float $thisKeys[] = `keyframe -q -sl $animCurve`; if (!size($thisKeys)) // if no keys selected get all keys $thisKeys = `keyframe -q $animCurve`; for ($keys in $thisKeys) // browse the keys { if (`fmod $keys 1` != 0) // if the keys have decimal places move them to the rounded keytime { if (`fmod $keys 1` <= 0.5) keyframe -e -t $keys -iub true -a -o over -timeChange (floor($keys)) $animCurve; else keyframe -e -t $keys -iub true -a -o over -timeChange (ceil($keys)) $animCurve; } } }

Have fun
