Convert AC3 29.97fps to 25fps
 

Hello

I repaired a very bad vhs studio convertion from 25 to 29.97fps makin it look interlaced, and now is back to 25

How can i sync the audio now? I tried besweet but the output sounds like a slowmotion scene

Do i have to make it go back to 23? how can i do that?
The source is AC3




Thanks and Saluts

...is there any freeware tool that i can use?

i learned ac3 pal or ntsc does not exist?, there is just ac3, with proper deinterlacing the audio should match exactly when fixing bad 25->30 fps transfer back to 25
