when i bought my DSLR camera Sony A57 i found that no video program understand Avchd Mts which can be set from 24 fps to 60 fps.
I found 1 program that allowed me to convert it to whatever format without quality loss and with all options i needed.
Program called iSkySoft video converter.
Initially program does not support 60fps output, but it does read it just fine.
Program is 100% capable to output 60fps video if you do small tweak.
Editing this line will help.
12 fps;15 fps;20 fps;23.97 fps;24 fps;25 fps;29.97 fps;30 fps,
You have to open file Format.dat with text editor and add it to what ever resolution or format you want.
You can do it individually or you can simply do "Find and Replace". It will add 60fps for all formats.
If you "Find and Replace" this
and replace it with
fps;30 fps;60 fps
This will search whole Format.dat files and add 60fps support for every codec and profile there is.
Hope that helps.
Program is so good, i bought it. Their online support is also great. They actually told me how to hack that file to get 60fps, it was very nice of them.
