  1. I have looked around in here and as I am a total video-noob I am sorry in advance if this is the wrong place to ask, or if the answer seems obvious to most users in here.

    I am a sports coach and use a video analyzer program to analyze the games we play. When I have transfered a game from the camcorder to my PC it is in mpeg2 format and aprox 4gb in size.

    In order to export videos from my video analyzer program the file I am using has got to be either avi or wmv, so I need to convert my mpeg2 videos to avi or wmv. I have used "Any video converter" so far, but my problem is the following: When I convert a video to either avi or wmv the quality of the video drops significantly (and the size drops to around 600mb - 1gb). I am very interested in analyzing in the original quality so this bugs me quite a bit. As mentioned I am a real noob, but even after tinkering with the options in AVC I cant seem to get the quality to anywhere near the original video. Can anybody help me?

    Thank you

    Any video converter is not the greatest tool on the planet (certainly not the free version)

    Try avidemux and experiment with codec settings. Another program (just for Xvid or Divx) is Autogk

    We can help but we need more info. How long is that 4 gig Mpeg2? A one hour Xvid would give you reasonable quality at 700 mb.

    Any conversion (from Mpeg2) will result in the loss of some quality.

    Try increase the bitrate for better quality or try use constant quality encoding if posssible in any video converter.

    Another easy application is freemake video converter, it can convert to both avi and wmv. In it can you use custom presets or edit the preset and adjust the resolution and bitrate.

    And if you want more detailed help please give more information about your mpeg2 video, like open it in mediainfo, view->text and copy and paste all data in this thread.

    Not sure which AVI format you are using, but say it's Divx/Xvid. Try doubling your bitrate with AVC. From your MediaInfo information, plugged into Videohelp Bitrate Calculator:

    Doubling your bitrate would give you this:

    Name:  br2.JPG

Size:  21.7 KB

    This is from AVC set to Xvid/Bitrate set to 4000Kb/s and MP3 audio @128Kb/s

    Try this or similar settings with WMV and see how it looks. Basically using a higher bitrate will give you better quality. (And a larger filesize.)
