+ | ===== Encoding Video for the E1000 ===== | ||
+ | As with many cellular and portable devices, encoding video can be a real pain in the ass. In order to maximize video playback time and quality while reducing battery-sucking CPU overhead special video formats are used. In the case of the E1000 the primary formats are MPEG4, 3GP and RealVideo. | ||
+ | |||
+ | * 3GP is perhaps the most common video format for cellular phones. | ||
+ | |||
+ | ==== Things You Should Know ==== | ||
+ | * Unless noted otherwise, the maximum bitrate is for **BOTH** Audio and Video. | ||
+ | * The E1000 video recording feature maxes out at 128kb/s, so videos you create with the phone will never look as good as videos you encode on a computer (which can go to 256kb/s). | ||
+ | * The transfer and encoding application that comes with the phone (PhoneTools) encodes at a pathetic 40kb/s, resulting in garbage video. | ||
+ | * The maximum video resolution is QCIF, which is 176x144 (PAL) 176x120 (NTSC). | ||
+ | * Streaming Video maxes out at 128kb/s. | ||
+ | |||
+ | ==== File Sizes ==== | ||
+ | Files created for the E1000 vary in size depending on the bitrate you use to encode the video. | ||
+ | * 128kb/s is approximately 16kB per second, or 500k per 30 seconds | ||
+ | * 256kb/s is approximately 32kB per second, or 1MB per 30 seconds | ||
+ | |||
+ | Consider your running time and the size of your memory card when encoding. | ||
+ | |||
+ | The E1000 usually includes a 32MB TransFlash card, and the phone has about 18MB of usable internal RAM, so | ||
+ | * the max size for a video on the TF card is: | ||
+ | * 32 minutes @ 128kb/s | ||
+ | * 16 minutes @ 256kb/s | ||
+ | * the max size for a video on the phone' | ||
+ | * 18 minutes @ 128kb/s | ||
+ | * 9 minutes @ 256kb/s | ||
+ | * If you buy a 256MB TF card (the largest currently available) you'll get an awful lot of video time: | ||
+ | * 256 minutes @ 128kb/s | ||
+ | * 128 minutes @ 256kb/s | ||
+ | |||
+ | ==== Video Types Summary ==== | ||
+ | * MPEG-4 is the format you'll want to use for best results, however the camera will only load .3GP files, not AVI or MPG4 or MPEG. | ||
+ | * Real Media (RM) can also be used. | ||
+ | |||
+ | ==== Encoding Software ==== | ||
+ | A major problem with encoding software is that the people who make it want money, and more money. | ||
+ | |||
+ | Most applications cost money or are crippled in some way. The software that comes with the E1000 (PhoneTools) is user friendly to the point of being useless. | ||

+ | The PhoneTools application is very user friendly, and by that I mean your grandmother can figure it out, but if you're any kind of power user its lack of customization options will make you insane. | ||
