Video: Bits vs. bytes

Another concept that's good to be aware of, as it pertains to compression, is that of bits versus bytes. I'm going to right-click on this clip, and I'm just going to go to Transcode Settings here. As we have looked at before, we had this Quality Preset here, and we notice that it says 4 Mb and 7 Mb. Well, oftentimes, we see a capital 'B' there. Well that actually makes a significant difference. If it's a small 'b', this refers to bits and if we let's say, for example, were to cancel this and go over to the Build menu, then when we see a 'B' here, it's a capital B, and this is referring to bytes.

Bits vs. bytes

Another concept that's good to be aware of, as it pertains to compression, is that of bits versus bytes. I'm going to right-click on this clip, and I'm just going to go to Transcode Settings here. As we have looked at before, we had this Quality Preset here, and we notice that it says 4 Mb and 7 Mb. Well, oftentimes, we see a capital 'B' there. Well that actually makes a significant difference. If it's a small 'b', this refers to bits and if we let's say, for example, were to cancel this and go over to the Build menu, then when we see a 'B' here, it's a capital B, and this is referring to bytes.

Typically, we refer to a capital 'B', bytes when we're talking about data storage. When we're talking about a data transfer rate, we're talking about bits, with a lower case 'b'. Now there are eight bits in one byte. So these numbers can vary wildly, so be careful about that. This is one of the reasons why, when we getting your Internet Service Provider all squared away, the rate sounds so great. You can get 5 Mb per seconds. It seems like, wow that's about the size of a song. A song is about 3 or 4-5 MB of music, so that means I can download in seconds.

And then when you actually get to using that Internet speed, it's nothing like that, and the reason why is the difference between bits and bytes, because the data rate that they are telling you is in bits, and the file that you're trying to download is in bytes, and so the same thing applies to Encore DVDs. So oftentimes, when it refers to 7 bits per second, it's referring to bits and when we are actually talking about storage, it's bytes, and they don't always match up. And because they don't match up, sometimes it can be little confusing where you might get a DVD that has one statement in gigabytes, and then something else might tell you that that DVD holds a certain amount of gigabits or video that has this many gigabits, or what have you, so it is just something to be aware of in the back of your mind, as you're creating your project, and you see a little tiny 'b', know that its bits and when you see a capital 'B,' know that it is bytes.

Q: On my version of Encore, I have the dropdown menu to select templates for making buttons and making a menu for my videos. Unfortunately, the menu only shows the General choices. I don’t have the weddings, cartoons, etc., templates available that are supposed to come with Encore. Why is this, and where can I get these templates?
A: In order to get the extra Encore templates, you'll need to get them from the discs that come with Encore, or the additional download where you downloaded Encore. Adobe makes this a separate download/installation because the files are very large (several GB).
