1.2 Known Problems
Known major problems with MagicHD:
• Playback of multiple layers of some HD media content types can be jerky or slow the system down: load management is not
yet implemented (whereby lower layers will skip frames to ensure the correct frame rate is maintained).
• When the text layer fills the screen rendering can be jerky due to huge font sizes.
• Aspect ratio appears to change when objects are rotated.
• With Windows 8 MagicHD must be run as administrator for media conversion to work.
• Some content encoded with the jpeg2000 codec causes ffmpeg (the tool used to convert media) to crash. If this happens the
user will have to convert the media offline with a different tool.
