here you can see that the video preview and timeline are mismatching
Hi mate, what do you mean by mismatching? the postion of the keyframe is incorrect ?
Can you send the scenes to us for troubleshooting?

how to pack the scene to send all files with models and textures.
you can see from the video that the blue line of timeline is going fast but the viewport is very behind. i have pointed in stairs shot so you can see what i mean.
at this time, the timeline is showing bedroom scene but the camera is somewhere in living room which you can see by half-height wall. https://youtu.be/ihPBhMxjRio?t=53
Got it, actually we can not make the keyframe corresponding to the clip position now 
especially one shot is too long. Sorry for the inconvenience. We will improve it in the future.
no issue, i just want to point out the issue. i manage to do animation by disabling automatic “View Interval”, so until the issue get resolve i think you set manual interval to default because it is very easy to mange and edit.
I know this is an issue they need to solve but are clips that long really the best option? A scene shouldn’t last longer then a few seconds. A scene that long will become boring for the average watcher.
Best to add multiple scenes to create a longer video
