We can tell you how to change the frame rate.
But since we know ABSOLUTELY NOTHING about your project, the various kinds of software you're using and what you want to achieve when the work is all done, we might be giving you bad advice in the long run.
This stuff ain't as straightforward as you may have assumed.
So you tell us more about the project: give us the details. We'll come back with more questions for you to answer, and after a fashion, you have the RIGHT answer... not necessarily the EASY answer. Dig?
Im not sure, what details you want to know, but il tell you everything I can.
So, the project is action video, recorded in 60fps, but then automatically converted into 30fps (720p). I want to alternate the slow-mo scenes and normal scenes(best in twixtor), so I want to speed it up. And with the speeding the video up i want to make fps bigger also(best the original 60fps). Thats it.
...recorded in 60fps, but then automatically converted into 30fps (720p)....
And how did THAT happen? What piece of software did this conversion?
I thought you said all the footage was at 59.94. What's the software you're using to check the frame rate?
"A sony action cam" doesn't say a lot about the nature of the footage, and it could be crucial to your work flow. What's the media container -- MXF? Quicktime? WMV? What's the codec -- H.264? MPEG?
...I want to alternate the slow-mo scenes and normal scenes...
Ah, this must mean you're using an editing application. Care to divulge which one you're using?
Have you chosen the normal-speed and slo-mo shots to make your life easier?
You mention Twixtor: how does this enter into the mix?
What will be the frame rate of the final, completed video file?
Now, let's talk AUDIO: I bet it has some. How was it recorded? Will you also use audio from slo-mo shots, meaning that it also sound slow and the pitch will drop a lot?
How will it be viewed -- at the movies? What's the player being used?
Will it appear on an HD monitor? Using what playback device -- a DVD player? Blu-Ray? Hard drive?
Will it only appear on YouTube or Vimeo?
Then there's also the machine you're using to create this project. It will also help to know the details about it.
If you think I'm joking about all this stuff, stay tuned to read what other people write in this thread.
So, the conversion was done in the camera, right after the end of recording. All the footage was recorded in 59.94fps(i didnt know that 0,06fps is such difference), the software i used to check fps is windows media player. The format is MP4, H.264. Final framerate after the render will be 29,97 fps. Audio wont be in the footage. All i want to do is higher the fps and speed up the video, so forget about twixtor, like i didnt mention it.

Some editing applications will automatically adjust for 59.94 footage in a 29.97 edit timeline, so you'd just have to conform the frame rate of the 59.94 slo-mo shots, and you may not need AE at all.
Oh, but wait: we don't know what you're using to cut this epic! Sorry, can't help you.......
Make sure the footage is properly interpreted and then use Time Remapping to speed up or slow down playback. There's plenty of info about Time Remapping in the help files.
