19th Entry

This week’s lecture continued from last weeks lecture about audio.

We started by revising the multimedia palette, quite an important idea to see what we can do with multimedia and the options available to us.

We then looked at the shape and dynamics of a sound wave. The frequency relates to the wavelength. If the length of the wave is short, the frequency will be high and if it’s long it will be low. The amplitude is the height of the sound wave. This can often be related to the volume. The peak is the sound waves highest point and the trough is it’s lowest point.

We also looked at the transition from analogue to digital audio. Digital audio can provide many editing benefits such as trimming, cut and paste, format conversion and re-sampling.

This week’s tutorial focused on video editing in the program Adobe Premiere.

The task was to look at some of the tutorials already contained within the program itself. Editing video is contains much of the same concepts of editing sound. We were able to trim the video, add scenes, delete scenes, create a splash page and add effects to both the video and the transactions between scenes. Although we didn’t cover it in the tutorial, we also had the opportunity to edit the sound played alongside the video. You can also edit where the scenes and the audio happens by adjusting it on a timeline.

The lecture was reasonably interesting, even though it did just stick to audio. It would be nice to go into some of the more advanced topics of multimedia instead of learning the basics to death. I mean we really didn’t need all the lectures we had on text to understand what it does. The tutorial was good though since it was my first time using video editing software. You can really see the similarities between Premiere and Flash, I guess that’s because they both deal with animation. Not quite sure what animations I’m going to do for the coursework yet though.

For my independent reading this week I’ve got an article about video editing and a link to some Adobe Premiere tutorials.
