Correcting Edits
I hate video taking, and the reason for that is simple: I look terrible in front of a camera.
What goes on after that, however, is something I find very fun and probably the most interesting bit of any videomaking process.

The Economics of Job Specialisation
It doesn’t make sense for everyone to do very little work spread across the entire field. There’s been much discussion of job delegation, but we’ve come to a pretty quick consensus about it (for once):
I, the most awesome with computers, will be responsible for video editing, including trimming, arrangement, colour correction, and post-production visual effects.
The very awesome Hilary Lok will be responsible for audio editing of the live audio that is to be recorded, a decision not originally included in our planning.
The Clarence Ng and Liam Yue will be doing special effects for the video, such as the inclusion of extended grassland (something that still hasn’t been found here yet!)
We’ll see how this works out.

Your Location Has Been Found.
First rule of the day: never, ever, attempt to make an appointment with anyone more than five times. After the fifth time (and you’re incredibly patient if it’s your fifth time), just forget about it. Ask the person to meet you instead. Or something.
Moving on…
I finally got around to scanning up our planning for the music video project. It would probably have been done a lot slower if not for a very real deadline, but anyway…

I know, I’m no artist, and neither was anyone else who was doing the storyboard for this project. Blame that the entire group happens to be predominately male, and while I have nothing against male artists, I fully confess than I believe none of the males in this set of people are artistically inclined.
Alex: Linear and Non-Linear Video Editing Systems
Having just finished a video editing project, I find it fair to launch into an explanation here.
Video editing suites have changed substantially over the past couple of years. At the beginning, film was edited manually. The special effects of that age were limited and often simple. Even transitions were incredibly easy.
The film industry term ‘cut’, to refer to a rapid change in scene (no less than 1 frame), is derived from the ancient technique of doing so. Back then, film strips were literally cut by the editor and pieced together again to form a final video. It was crude, and any error on the part of the editor would result in irreparable damage. You can imagine the pressure that they were under at that time.
It also meant that video editing was linear. Editors had to start at the beginning and piece everything together bit by bit. Sure, they could assemble everything outside of sequence, but it still went from the beginning and straight to the end. Nothing more.
These controls were specially designed for linear video editing. Image via Wikipedia.
When computers were invented, they further enhanced the limitability of linear editing systems. At this point, random access still had not been invented, so that the editor had to load pieces up in order and assemble them like so. I have never run a linear editing system, so I can hardly go into the details.
Today, however, the majority of video editing happens on non-linear video editing software, like iMovie, Adobe Premiere, or Sony Vegas. These programs are use non-destructive video editing techniques, rather like how Adobe Photoshop works.
The principle is simple. These editing suites, instead of editing the video, simply write a text file stating the location of the video clip, which sections of the video clip to play, and then where that is placed in the relative timeline. This means that the original video file is never altered or edited — being non-destructive — but the fact it writes the relative position on the timeline also means that they could be rearranged at leisure. After all, you’re not moving about 1.5Gb of video data — you’re simply rewriting one line of text in a 1KB file.
Naturally, this revolutionised the film industry. Now, nearly all video editing takes place on some non-linear video editing software because of its ease.
The downside to using non-linear video editing software was that none of the actual video files were placed together. As a result, the software file itself was meaningless. To share the actual video, the user needed to render the video out, so that each individual bit was converted into a video, and assembled to form the final film. This process often took hours, perhaps even days, depending on the intensity of the editing. In other words, the system traded the time around, granting ease and speed of editing and increasing time needed to produce the product.

Still, Adobe Premiere runs fine on me, and I’m not complaining. Even if it does drain my RAM a bit. A bit more than a bit.
Get the joke?
