I saved movie for high definition (about 1080p). But when I had opened it, I got some problem.

   1. the file is contracted and the sound or many texts doesn't work .

   2. then it was cut for a shorten size, moreover i cant fix it in movie maker.

   3. some text get lost and the time is shorten (in movie make is about 14 mins but if i open in high-definition form it is about 10 mins )

   how can i change this file to save for common computer or fix it in movie maker?

   how can i get the old file to fix????
