240 FPS clips don't seem to be 240 FPS at all.

[Sang5FEA]

When putting a 240 FPS clip into my timeline, and previewing it, it doesn't look like 240 fps, but more like 30-35 fps. I thought that this was only for the preview,  and when I export it, it would be 240 fps. When I was done editing, then exported, the video wasn't in 240 fps at all. It looked like the same fps in the preview. Sorry for  bad english, it is not primary language. Help please?

Could you post a screenshot of your export settings showing this information:

Ok it this

I just notice in the source, it say 29.97 fps. Original clip I record was 240 fps. Why it change the fps?

and also I try change fps in the export setting. That why it say 60 fps from output, but it actually 29.97 fps?

Before dragging your clip to the timeline, right click on it > Modify > Interpret Footage.

A window will appear. In this window, you need to change the assume this frame rate to 29.97

As for the export window you shared, source is 29.97 because it is reading the frame rate of the sequence and not the clip.

The clip slow down. Is there way to not have it slow down???

I'm sorry but you lost me. Can you please elaborate what you are trying to achieve so I can help you?

When I did the steps you told me to, and I preview it in the timeline, it is in slowmotion for some reason.

Almost no hardware can display a 240fps at normal speed. The reason to shoot at that rate is to get good quality slow motion. When you put that high framerate clip on your 50 fps timeline to get it to play at normal speed Premiere has to discard 190 frames every second, that might be the reason the clip looks as it does. Using optical flow might help.
