“The Wii plays videos?”
Yes actually, it does. As strange as it may sound, the Nintendo Wii can play videos via its Photo Channel. Yes, the same channel where you can also look at pictures. The supported specs for videos are to the right.
“Why Motion JPEG?”
No one knows for certain except Nintendo. The best guess I’ve seen is that because the Photo Channel supports JPEG photos, a side effect was that it could also read Motion JPEG videos. So, Nintendo decided to add it as a feature.
“Do I need QuickTime (Pro)?”
No. Nintendo specifies QuickTime video because most people would know what that is and recognise it when they see it. The OpenDML JPEG format works just fine.
“I converted a video and now it’s huge!”
That’s the unfortunate thing about the Motion JPEG format. It converts every frame into a JPEG image and so a 30 second 24fps video will be made up of 720 JPEG images. If you find you can’t fit your video onto an SD card, try cutting the number of frames as well as sacrificing quality.
“Is there a 15 minute limit?”
Well no, not a 15 minute limit. Not a 30 minute limit either. There is a limit on the over length of the video. Confused? Playing a video all the way through depends of the quality of the video you are watching. Lower quality the longer the Wii will be able to play it.
A classic sign that the video will end is that the playback will get choppy and start skipping frames as the Wii runs out of memory. Nintendo needs to fix this.
