Video Compression Issues

My IMU contains a fair amount of video. In a perfect world and given perfect conditions, this would not be a problem to implement. Here’s the short version of what has gone right and wrong during video production.

WHAT WENT RIGHT:
Human subjects were agreeable to being filmed. Human subjects include 1) instructor 2) semi-willing student. Some very interesting and humorous outtakes resulted from filming. Those are being reserved for the Director’s Cut Version, available exclusively from me. :)
Rendering of video mostly completed. Video portion of project remains on schedule!

WHAT WENT WRONG:
Filming occurred under less than perfect conditions. Due to scheduling conflicts, the original videographer (who is experienced and acutely aware of lighting and sound issues) was unavailable. Instructor/client, in a good faith attempt to keep project on schedule, arranged for filming by third party in order to have video to me in time for editing. Unfortunately, the third party was inexperienced, resulting in poor lighting and volume as well as camera experience.
No access to raw video footage (raw = the actual digital video tape). Although I asked for the raw footage of the tapes, I was given a windows media (.wmv) version to edit. Upon investigation, it was determined that the raw footage was no longer available!!
Less than stellar end result. Converting the video into a working version further compromised the quality. Then I determined that uploading .swf files to my server wasn’t going to work (files were huge, uploading kept timing out), I went back and converted the edited versions to flash (.flv). This greatly reduced the file sizes and uploaded with no problem. However, the sacrifice was apparent in the quality of the video.

Conclusions: Due to time constraints and scheduling conflicts, this outcome was unavoidable. In the future, I will make every effort to ensure that quality is not sacrificed. If time and budget permit, I would like to re-record these videos at a later date with the professional videographer.

Joy - It might be a good idea to see if some students might be willing to make their own videos to submit, although I imagine the expert is the one who should 'teach' this info? Thanks for sharing the challenges! Too often, we only see the end result and no explanation.
