It really uses a lot of bandwidth, but the encoding "profile" they use is with the lowest compression in order to save on energy consumption. So basically the HD video encoded by iPhone is wasting a lot of bandwidth in order to compenstate for it's weak processing power. You can get the same visual quality with less than 1/3 of this bandwidth. The "HD like" bitrates I have given above are close to what youtube uses too. We're speaking of web video here. Bluray goes at more than 40mbit/s which is to ENSURE that the visual quality is high at all times. This is not feasible on the web. iPhone is a poor excuse for encoder.

For example the iPhone 4 records 720p (16:9) at about 10 mbit/s. The bit rates you refer to (600kb/s) result in poor quality DVDs. Fortunately at least in the USA broadband is generally able to suck down 10 mbit or more. Bly-ray, perhaps the most "professional" format of all encodes 1080p @ either 25 mbit/s or 35. I forget which. This should perhaps be updated. For example the iPhone 4 records 720p (16:9) at about 10 mbit/s. The bit rates you refer to (600kb/s) result in poor quality DVDs.

The requirements are so high that many enthusiasts consider the bandwidth in the BluRay and HD-DVD to be inadequate to get a “decent fidelity” video playback. Well this is formally true … in some cases. In practice we’ve lived with the low standard definition(SD) content for more than two generations and if the technology still struggles with single consumer solutions, what do we do with HD on the web then? Besides the raw bandwidth there are other solutions improving the odds in our favor. [...] [...] High definition video imposes huge requirements on bandwidth for the video data stream.
