I need to convert an mp3 from 25000 to 24019 fps because this is the frame rate of my video(i found it with AviSync):can i do it with BeSweet?It seems that i must reconvert to mp3 or another format since if i choose only tho ota switch i can't start the conversion.Anyway when i try to convert it to Wav or AAC the result is just a clipping,no sounds or voices.If i try to output another mp3 BeSweet just crashes.

i dont know if the audio framerate conversion is already stable in besweet, but i want to say that changeing the framerate of the video stream to match the audio is a better way, cause its lossless

But how can i do it?And is there a way to exactly know which is the framerate of the audio?Thanks!

eg you have an audio stream which is 60mins long and in sync with the 25fps video
now when the user ticks 25fps -> 30fps it calculates 60*25/30 = 50
-> the output audio stream will have 50mins, being in sync with the 30fps video stream
And to which frame rate i must change the video to have syncronization?is it really that hard to read the guides?
