Miglia Technology EvolutionTV - Manual (Page 44)

Introduction
EvolutionTV supports various capture formats, which can be played back by most if not all software
video applications. However, you may need to install additional video codecs in order to play back
some formats. A Video codec is an extenstion, which enables a software video player (like
QuickTime Player) to read a video file.
I. Software Video Players
Miglia currently recommends two software video players:
• QuickTime Player: QT Player is part of a standard Mac OS X installation. You will find the
software in the Applications folder on your hard drive.
• VLC Media Player: VLC (Video Lan Client) Media Player is an open source project available on
several platforms. VLC provides broad compatibility and excellent
performance.
II. Required Codecs
You may need to install a video codec to playback some formats. The requirements are listed below:
• MPEG-2: MPEG-2 playback is directly supported by VLC, without any additional
software installation. If you wish to play back an MPEG-2 file in QuickTime
Player, you will need to install the MPEG-2 Playback component available
from Apple’s website (Note: The MPEG-2 Playback component is not free of
charge).
• MPEG-4: No additional codecs are required to playback an MPEG-4 file. Simply open
the file in QuickTime Player or VLC.
• DivX: To playback DivX files, you will need to download the free of charge DivX
component available from http://www.divx.com
III. Playback problems
Please note that playing back video files requires more processor resources than recording them
with the TV hardware.
If you have slower G4 processor, you may not be able to playback full size video. Should the image
stutter while you play back the movie, please open the ‘Show Info’ window located in QuickTime’s
Window menu. The info will help you determine the current frame/sec rate for the file you are
playing.
Note that the normal frame rate for PAL (Europe, Asia, Australia) is 25 fps, while NTSC (North
America, Japan) is 30 fps. If the frame rate is below these values while playing back, try quitting
other applications or reduce the screen size.
