Canon FS series for standard definition; HF series for high definition. You will need an optional high capacity battery. You will need to get big memory cards. Most consumer camcorders come with a remote. Download the camcorder manual and verify.
For standard definition, you will need to convert the video before a computer video editing application can deal with it. With high definition AVCHD files you will need an editor that can deal with MTS files. The software in the box is useless.
Does anyone know of a decent 3-5hr camcorder (HD preferred, not required) with a remote control? As a teacher, this would be excellent. SD card use is preferable.
