MPG playback wierdness

Hello,

I have exported some very short AVI clips from Vegas into MPG format, using the Main Concept MPEG-1 encoder. The clips look great when I play them in Windows Media player off my hard-disk. But after I upload the clips to the web and view them via a web browser on different machines, Windows Media player doesn't seem to play the last 1 or 2 seconds of each clip.

For example, I have one clip that is 3 seconds long. When viewing over the web, Windows Media player downloads the file and starts playing it. But according to Media Player, the clip is only about 1.5 seconds long. The last 1.5 seconds have been "lost". Of course, if I right click and "Save As..." the file from the web browser, copy it to the local hard drive, and *then* play it back in Media Player, it plays the whole thing (all 3 seconds).

It seems that when I reduce the bitrate of the MPG file, this problem seems to go away. But by then, I've reduced the bitrate below the quality threshold that I'd like to use for the clip.

Does anyone know if this is really an encoding problem, or is this just a Windows Media Player bug?

Sincerely,

Nate Hayes

I'm not a techie, but I've seen the identical problem in Media Player with MPEGs I downloaded from the net. I don't think it's a VV problem. I've created MPEG files in the "baby brother" VideoFactory and they went in fine.

I think you are right. When I use RealPlayer to view the MPG files, they play just fine all the way to the end. It seems like some sort of buffering bug in Media Player.

Sincerely,

Nate

Sounds like a Media Player thing. I've see what you saw and sometimes some vids stop minutes short of the end that play fine in other players. Also if you change any of the video settings in Media Player when its running sometimes that will cause Media Player to start playing in slow motion, studder or stop completely. Even the contrast control works backwards. Moving it left gives more, not less contrast. What do you expect, its from Microsoft. <wink>
