Thanks for the replies, shooting the video at 50 fps and intepreting it to 25 was not an options since the song was way to fast for anybody to sing in sync at 200% speed.

I’ve found out that the best approach is to intepret the footage to 25 and speed it up 140%.

The only bug for me now is to keep the audio in sync with the video while editing, not a huge problem but if there’s a way to fix this it would be great.

It seems like this slow-motion effect is much easier if you’re in an NTSC land. By speeding the song up by 40.06% shoot it at 50 fps and intepret it to 29.97, unless you have a very slow song where you would be able to speed it up by 50%, but that was not an option in my case.

Well, I know about that feature, but than I would have to slow it down to 35 fps (0,7*50=35) which is not exactly a good frame rate to work with, especially since not all the video is taken at 130% speed.

Then I would have some of the video in a 50 fps sequence, and another at 35 fps. Is there any way to mix those two sequences together?
