Moving camera in relation to a moving object causes stuttering/lag

[TibiaMaster1]

this still seem to be an issue… any update or possible solution on fixing this?

Hey there @TibiaMaster1! Welcome back to the community! Have you given Batsi’s solution a try? Having lock frames seems like a solid idea, though I hadn’t given it a shot myself.

it didnt work but i found another way of fixing it. basicly the solution is to bake it in the curve editor by selecting all points and pressing filter. then in the options you have to specify how much you want to smooth it out (for all parameters which contains xyz of position and rotation, usually 3 to 5 works on 24fps sequence. that basicly gets rid of all the jittering. hope that helps. ^^

After a lot of testing I finally figured out the issue. There are two possible fixes, either setting your project to a fixed FPS in your project settings, or setting the tick group of your actor(s) to postphysics using the line of code
PrimaryActorTick.TickGroup = TG_PostPhysics;
in the BeginPlay function. (should be a node to change the tick group if using blueprints)
setting the project to a fixed fps should work for a lot of cases but may lead to other unintended issues so changing the tickgroup is what I would recommend.
I believe this is caused by FPS smoothing or inconsistencies in fps, leading actors to tick at different intervals.

Hello,
I’m having the same issue. Can you give me more info on how I set up the “BeginPlay” function as you described. All of my vehicles are blueprints.

I’ve been working on an animated film project for months with custom made vehicles that deform realistically. Everything is ready to go and now this is happening when I record the vehicles with take recorder. I know there must be a fix because in gameplay they move smoothly.

Any info you could provide would be greatly appreciated. I’d be willing to send you a tip as well.

Normally, this happens when more than one thing has control over the actor. The level sequence and some game logic of some kind, for example.

This chapter in the Vis Guide looks pertinent.

I was already running Take Recorder in the desired FPS, and it was still stuttering in Sequencer with the same FPS. I’m not sure about the fixed FPS and PostPhysics solution mentioned above, they didn’t work for me or I didn’t implement it properly.

However, this filter solution seems to have eliminated the jittering for me! Thanks a lot!
