Video Production PowerPoint

Here is the PowerPoint from the Video Production lecture given this week:

Video Production

You will have a brief quiz first thing next class.  A demonstration on how to use the video camera, tripod and microphone will follow.

Shooting Over To Video Production

Next week, we will begin the process of learning what it takes to write, shoot, produce and edit a news/feature report.  There will be a lecture on both video production and on performance development.  You will be quizzed on the lecture.

There will also be an in-class demonstration/tutorial on the use of both the video camera and on Adobe Premiere Pro.

You will be required to turn in a written proposal on the news or feature report you are planning on producing.  Your proposal will include, but is not limited to:

  • Rationale for your story.
  • Your choice of talent (who will do the stand ups and voice-overs).
  • Potential selection of people to interview (check guidelines on the website for this).
  • Potential location(s) where you will shoot your story.

This proposal is not due just yet, but for your next blog post (this Friday or next Friday), please write about what you are considering for your news/feature report.  Some examples can be found on the course website at: https://gatorjbone.wordpress.com/newsentertainmentfeature-package/

Does Bitrate Really Make a Difference In My Music?

What Is Bitrate?

You’ve probably heard the term “bitrate” before, and you probably have a general idea of what it means, but just as a refresher, it’s probably a good idea to get acquainted with its official definition so you know how all this stuff works. Bitrate refers to the number of bits—or the amount of data—that are processed over a certain amount of time. In audio, this usually means kilobits per second. For example, the music you buy on iTunes is 256 kilobits per second, meaning there are 256 kilobits of data stored in every second of a song.

Does Bitrate Really Make a Difference In My Music?

The higher the bitrate of a track, the more space it will take up on your computer. Generally, an audio CD will actually take up quite a bit of space, which is why it’s become common practice to compress those files down so you can fit more on your hard drive (or iPod, or Dropbox, or whatever). It is here where the argument over “lossless” and “lossy” audio comes in.

Lossless and Lossy Formats

When we say “lossless”, we mean that we haven’t really altered the original file. That is, we’ve ripped a track from a CD to our hard drive, but haven’t compressed it to the point where we’ve lost any data. It is, for all intents and purposes, the same as the original CD track.

More often than not, however, you probably rip your music as “lossy”. That is, you’ve taken a CD, ripped it to your hard drive, and compressed the tracks down so they don’t take up as much space. A typical MP3 or AAC album probably takes up 100MB or so. That same album in lossless format, though—such as FLAC or ALAC (also known as Apple Lossless) would take up closer to 300MB, so it’s become common practice to use lossy formats for faster downloading and more hard drive savings.

The problem is that when you compress a file to save space, you’re deleting chunks of data. Just like when you take a PNG screenshot of your computer screen, and compress it to a JPEG, your computer is taking the original data and “cheating” on certain parts of the image, making it mostly the same but with some loss of clarity and quality. Take these two images as an example: the one on the right has clearly been compressed, and it’s quality has diminished as a result. (You’ll probably have to click the image for a closer look to see the differences).

Remember, of course, that you’re still reaping the benefits of hard drive space with lossy music (which can make a big difference on a 32 GB iPhone), it’s just the tradeoff you make. There are different levels of lossiness, as well: 128kbps, for example, takes up very little space, but will also be lower quality than a larger 320kbps file, which is lower quality than an even larger 1,411 kbps file (which is considered lossless). However, there’s a lot of argument as to whether most people can even hear the difference between different bitrates.

Does It Really Matter?

Since storage has become so cheap, listening to higher-bitrate audio is starting to become a more popular (and practical) practice. But is it worth the time, effort, and space? I always hate answering questions this way, but unfortunately the answer is: it depends.

Does Bitrate Really Make a Difference In My Music?

Part of the equation is the gear you use. If you’re using a quality pair of headphones or speakers, you’re privy to a large range of sound. As such, you’re more likely to notice certain imperfections that come with compressing music into lower bitrate files. You may notice that a certain level of detail is missing in low-quality MP3s; subtle background tracks might be more difficult to hear, the highs and lows won’t be as dynamic, or you might just plain hear a bit of distortion. In these cases, you might want to get a higher bitrate track.

If you’re listening to your music with a pair of crappy earbuds on your iPod, however, you probably aren’t going to notice a difference between a 128 kbps file and a 320 kbps file, let alone a 320 kbps file and a 1,411 kbps file.

The other part of the equation, of course, is your own ears. Some people may just not care enough, or may just not have the more attuned listening skills to tell the difference between two different bitrates. This is something you can develop over time, of course, but if you haven’t yet, then it doesn’t particularly matter what bitrate you use, does it? As with all things, go with what works best for you.

So how high of a bitrate should you use? Is 320kbps okay, or do you need to go lossless? The fact of the matter is that it’s very difficult to hear the difference between a lossless file and a 320kbps MP3. You’d need some serious high-end gear, a very trained ear, and a certain type of music (like classical or jazz) to hear the difference. For the vast majority of people, 320kbps is more than adequate for listening. You don’t need to pain yourself with finding lossless copies of all your favorite songs.

All that said, lossless file types do have their place. Lossless files are more futureproof, in the sense that you can always compress music down to a lossier format, but you can’t take lossy files back to lossless unless you re-rip the CD entirely. This is, again, one of the fundamental issues with online music stores: if you’ve built up a huge library of iTunes music and one day decide that you’d like it in a higher bitrate, you’ll have to buy it again, this time in CD form. You can’t just put data back where it’s been deleted. When possible, I always buy or rip in lossless just for backup purposes, but I’m a little overly OCD—MP3 is a great standard, and it isn’t likely to change anytime soon, so unless you plan on converting your music at a later date, you’re probably fine just ripping or buying in MP3 format.
