Exported to 60 FPS but still the video is in 24 FPS

OK now i understood the difference between my video and those youtube videos. I don’t want to do interpolation at all. I will continue my project by recording the videos in 60 fps instead of 24.

Now i have another Doubt.

I just played the videos (Exported one and the original source video ) on my TV. I compared the both the video and they were same and the 60 fps does not have any impact on the video.

But when i speed up the video with the remote for the TV , i can see the difference. The original Video(24 frames ) changes with frame by frame when i speed it up . But when i speed up the other video (60 fps) , the video changes continuously (not frame by frame ) and it looks like Interpolation. Is that a reason for Broadcasting Stations not using 24 fps ??

I have another question, How do the video will look if i have used Transitions and Effects in the mid of the video ? What if i merged an another video clip that is created inside the shotcut which shows an Text in a black background with a motion . Will the overall exported video looks like same or will they have an impact on the exported video??

I mean the souce video would like 24 fps when it exported to 60 fps but what about the text and transitions ?? . Converting an video form 24 fps to 60 fps is different from creating an video inside the video mode (1080p and 60 fps) . SO tell me how will the video would like ??
