if i click that, it only open a window to see the frame. it doesnt "play" or move like a video preview or i can say more like frame preview

[Selur]

Yes, it doesn't play and it is not meant to.
You can scroll through the clip, jump around in it, but you can't playback.
If you need a playing preview, since you can't work things out otherwise: Hybrid simply isn't the right tool for you.

but my original question was why the playback played at 2x instead of normal speed for some files like mp4 and mkv the TS file played just fine

[Selur]

The 2x speed can happen if you use the normal preview while use frame interpolation since MPlayer which doesn't support interpolation is used for the normal preview.
