The recompression argument makes sense because the format did not change (both WMV). So, theoretically, there should be a slight degradation of video quality. Fortunately it is not visible by the naked eye. </p> http://www.howtogeek.com/forum/topic/bytes-disappear-in-movie-maker#post-33416 Sun, 06 Jul 2008 23:58:19 +0000 ScottW 33416@http://www.howtogeek.com/forum/ <p>whs, when you modify a video with Windows Movie Maker it will always be recompressed on output. Also, you get very limited control over the output specs, so WMM is making some choices for you. The output is being rendered at a lower bitrate (more compression) than the input video.</p> <p>To really see the information on what the bitrates are, you need a tool such as <a href="http://mediainfo.sourceforge.net">MediaInfo</a> which will tell you more about a video file than you probably want to know. But, you can look at the codecs that were used to compress each file the framerates, bitrates and so much more to see exactly why the size changes. </p> http://www.howtogeek.com/forum/topic/bytes-disappear-in-movie-maker#post-33413 Sun, 06 Jul 2008 22:48:27 +0000 The Geek 33413@http://www.howtogeek.com/forum/ <p>Did the video format change at all after adding the music?</p> <p>I'd guess that the clips ended up being compressed with a newer/different algorithm than they originally were saved in, which made the file size smaller. </p> http://www.howtogeek.com/forum/topic/bytes-disappear-in-movie-maker#post-33211 Sun, 06 Jul 2008 10:17:02 +0000 whs 33211@http://www.howtogeek.com/forum/ <p>This is not a problem but it made me curious. - I have taken a few of my video clips (WMV format) and added music to them with the Windows Movie Maker. Common logic would tell you that this adds bytes to the clip - but quite the opposite. The clips WITH music have about 20 to 30% less bytes than the exact same clips WITHOUT music. Would anybody have an explanation for that? And I cannot observe any loss of quality or any other change whatsoever. </p>
