I have Windows 8.1 Pro. I made a football highlight video with a bunch of 3-8 second video clips in .MOV format. Used slow-mo in some of them and added a song and a title slide. I saved it as a movie maker video (wlmp file) and played it at least 5-7 times and it worked just fine.
A few hours later was going to play it again. It played, but had no sound. I checked all the volume settings and all was fine. I paused and restarted the video several times and eventually just played it all the way through. Still no sound, but all videos played. I close Movie Maker and open it back up and now I have sound. BUT, now I have a black screen in the preview window on all videos except the title and the first video.
I search through this forum and see I am not the only one with this problem!! Wow!!
So I find that I need to check my video card (it's fine according to my computer).
I see I need to do something with codec, but I'm not sure how to do this.
I also see that I can convert the file to .wmv format and that will solve a bunch of issues.
So I do this with one of the videos and start a new project in Movie Maker. The video plays and I edit it. I set my start and end point, then I copied and pasted a part of it and put it at 0.5 speed. I play it probably 5 times and it works.
I convert another video and add it to project. I put in a title slide.
I go to play again.... And same problem. Title slide and first video plays but the rest do not. There is a black screen.
The 1st, 2nd and 3rd videos are all from the same file, same video, just clipped in a couple of different places and one of them put in slo-mo.
What is this problem!?!?!?
