How to record gameobject positions during playmode in the timeline editor ?

Hello,

I'm trying to build a simple cinematic scene : the player is moving through the space and talking. It is in first person mode. So, i used the timeline editor by recording the player transform position in different keyframes. But it takes a lot of time and it s hard to synchronise with the speech ( for example, at one moment i would like the character just to turn the head). Is there a way to do it through the playmode and record the characters movements in the timeline editor ? thanks !
