File-based camcorders from various manufacturers record video and audio into files of specific formats organized within specific directory structures. These formats include Panasonic P2 camcorders, Sony XDCAM HD and XDCAM EX camcorders, Sony CF-based HDV camcorders, and AVCHD camcorders.
Camcorders recording in any of these formats typically record to hard disks, optical media, or flash memory media, not to videotape. These camcorders and formats are therefore called file-based, or tapeless, rather than tape-based.
The video and audio from a file-based camcorder are already contained in digital files. No capture or digitizing step is necessary to bring them into Premiere Pro. Reading the data from the recording media and converting it to a format that can be used in a project is instead called ingest. Premiere Pro ingests files in any of these file-based formats from any of their media.
Adobe provides workflow guides for P2, RED, XDCAM, AVCCAM, and DSLR cameras and footage on the Adobe website.
