 A cam is a theater rip usually done with a digital video camera. A mini tripod is sometimes used, but a lot of the time this won't be feasible, so the camera may shake. Seating placement isn't always ideal, and it might be filmed from an awkward angle.
 
-If cropped properly, this is hard to tell unless there's text on the screen, but a lot of times these are left with triangular borders on the top and bottom of the screen. Sound is taken from the onboard microphone of the camera, and especially in comedies, laughter can often be heard during the film. Due to these factors picture and sound quality are usually quite poor, but sometimes we're lucky, and the theater will be' fairly empty and a fairly clear signal will be heard.

-A re-encode of the final released Blu-ray, downscaled to 480p resolution (720x480 @ 16:9, any other AR may be a different resolution). If possible this is released PRE retail. It should be excellent quality for the resolution. Bitrates may vary, but these are generally encoded to DivX, XviD, or AVC and offer the tradeoff of a small perceived quality reduction over the original source while drastically reducing filesize. These are generally MKV or MP4, but some DivX/XviD are around as well which use AVI.

-A rip of a film from a streaming service, released in 1080p resolution (1920x1080 @ 16:9, any other AR may be a different resolution). These are nearly as good as a Blu-ray source but can suffer from audio lag or visual artifacts from the adaptive bitrate of streaming services. If a ripper's internet connection drops to a point where the bitrate lowers, the source bitrate could change dynamically, causing variations in picture quality. Most releases that suffer from an extreme amount of visual artifacts are NUKED and a PROPER is generally released to fix any wild variations in adaptive bitrate.
