OK, so save the day would be a wee bit on the over dramatic side but the simple fact is there was a task to do and had it not been for a computer with Xubuntu 10.04 and OpenShot the task may not have been able to be finished.
At work, I had a video file that needed about 30 seconds trimmed from the beginning and unfortunately Windows lacks any worth while free (open source or otherwise) video editors and the iMac's Final Cut Express would not even import the MP4 file I needed to edit.
Loaded up Xubuntu and OpenShot, trimmed the file, exported it and uploaded to Youtube. I did have to install the MP4 codec for the export, but after that I moved the file to my main machine to upload to Youtube and the job was finished.
Hooray for Linux and Open Source!
