I am able to add the media, so I know the format is acceptable but for example, the video has 3 min, and in the timeline only show 2 seconds of the video and 5 seconds of the audio. Have no idea what I have to do to show the full video on the timeline. I am using the movie studio 17.
I can't see enough of the video to discern its format, but it appears to be some sort of third party screen capture software or otherwise non-camcorder video.
I'd recommend opening that video in the free download MediaInfo. In MediaInfo, set View to Text and then copy the text in this report and paste it to this forum. Once we know all the specs of the video we'll better be able to offer you advice.
