A couple of people have reported issues playing some of the videos with Windows Media Player. The sound plays fine, but the video shows a black screen.
I’m afraid I have NO idea what’s causing that.
I’ve not been able to replicate it myself, and I compress all the videos in exactly the same way using the same program on one of the same two Macs each time; it doesn’t seem to correlate with which Mac I prepared the final video on… which was the only thing I could think of that might be different. So I’m at a loss.
I will investigate more, but without being able to identify anything different my end it’s really hard to know where to start.
VLC media player, an open-source player which you can download for free here http://www.videolan.org/vlc/index.en-GB.html plays the rogue files just fine (as do our Macs and iPhones etc of course).
So I don’t think there’s anything fundamentally wrong with the files, and I have no idea why WMP sometimes throws a fit. If anyone has any ideas please let me know, it’s very perplexing.
In the meantime, if you experience the problem, please let me know and let me know which videos it happens on… and please download VLC media player so you can still watch the films. Apologies.
