The Dark Sky Company, LLC 6 years ago Video I'm uploading are playing back at 50 times normal playback speed when I press the play button. If I then rewind the video and play it again it's fine. This is a little hard to see at first because they're time-lapses, but If you look at the duration of the movies you'll notice that some are over a minute long. They're all online here: vimeo.com/lewitt I'm uploading h264 compressed QuickTime movies with a very high bitrate and a framerate of 25fps. I've seen this problem on other people's videos, so I bet it's already been discussed and solved but I could find a thread on it. Any help would be greatly appreciated. I have another 16 time-lapses of murals to put online in the next 24 hours to coincide with an opening at MASS MoCA. Thanks in advance.
