Budget Your Bits for the Best Quality Video

March 1, 2010

Aside from the codec and frame size, the most important factor in determining the quality of the finished product when rendering video is bitrate.

The term bitrate refers to the number of bits per second used to encode a given clip. Just as the quality of a still image is measured in resolution, the quality of a video file is measured by the bitrate.

For video destined for the web, you don’t want to encode with the bitrate set too high for several reasons:

1. You will make your viewers wait unnecessarily long before they can start viewing your video.

2. Higher bitrate videos put an extra strain on your server and will cost you more money in extra bandwidth.

3. Older computers will have a hard time decoding very high bitrate codecs in real time, leading to dropped frames and jerky appearing motion.

4. Uploading will be slower.

5. You’ll use up unnecessary room on your server and local drives.

On the other hand, you don’t want to encode video with bitrate too low either otherwise the visual quality will suffer – there will be pixelization and blockiness, especially in any areas with motion.

Let’s Get Progressive

“Progressive download” means, as soon as your viewers click to view a particular video, the video starts downloading to a hidden cache file on the users machine.

As soon as enough of the video has downloaded to provide the user with an uninterrupted viewing experience, the video begins playing (as long as it’s set to: autoplay = “true”).

With a video that is encoded at a lower bitrate than the total bandwidth of the connection between the video server and the viewer, the video will start playing within a second or two, and continue without stopping. This is obviously the goal to aspire to for most purposes.

Fortunately, choosing the best bitrate to achieve this goal while retaining visual fidelity is no longer just a matter of luck.

Organic Cooking

March 1, 2010

If you’re interested in organic food recipes there are some excellent websites which are now offering information, many with organic cookbooks available.

You’ll find some of these sites can give very useful and detailed information. Sometimes, though, too much information can bury you in detail. What you really need is straightfoward information to steer you through the confusion, so it’s worth looking for sites that have information in a clear, uncluttered fashion.

Since most people who are interested in organic recipes are likely to be considering their health, primarily, it only makes good sense to find information sites that offer healthy meals. Because a meal is made with something organic doesn’t mean it’s a healthy meal, you can eat too much read meat and starchy food as easily with organic produce as you can with the regular kind.

So looking for a suitably wide range of organic recipes is a good idea, just don’t forget to allow yourself an occasional treat as well. After all, variety is important. The one thing you don’t want to do is boring yourself off otherwise healthy diet.

Keep in mind is that really good quality organic produce is very seasonal. You just don’t get certain foods fresh all year round – nor should you. So select recipes according to the time of year when you’re eating.

For those of your who are really serious about healthy eating it pays to get a good quality cookbook to teach you a few of the wonderful recipes available when you have food that actually tastes of something. Your health and your body will thank you for it.
