I am working on a training video for work. Our intranet site has a limit on file size. My current video is too large - regardless of what format I save it in or the sizes of the image and sound files I am using. I previously created another video of the same format (MP4) that was twice as long but the file is 146 MB. I don't know how to produce this video so that it is small enough to fit on our intranet.

The original webinar that recorded is only 38.4 MB. How is it possible to edit out some of the video, reduce the background noise in the audio, and replace the video track with jpegs (power point slides saved as jpegs) to produce a file that is 2,049% larger?

I do notice that the edited version is stereo instead of mono, but PowerDirector 13 does not have a mono option for audio that I can find. The last video was the same - mono unedited and stereo edited. It did not have the size balloon like this one. I also notice that the data rate is substantally higher in the edited version, but I don't know were (if) I have any control over that.

I am pretty sure additional information in needed so please feel free to ask. Luthien Tinuviel
