M2ts Video footage has been deleted off my SD card. I have managed to recover around 500 clips on the SD card and I can play them on VLC player or on Premier. However the recovered m2ts files I need (my sisters wedding footage) are only around 3seconds long, when originally the files were a lot longer in length. The footage is also often jumbled and jumps from my sister's wedding footage to something that was shot a few months before. I'm not sure if the clips are just heavily compressed and if there is just a way to expand them.
Does anyone know how I might be able to rebuild or extend the m2ts files. Or if there is a programme or a way to restore the clips fully.
Any help greatly appreciated.
