SP (standard play), EP (extended play) and SLP (super long play) are different recording modes for VHS and other video tape formats.
SP mode is the most commonly used and produces the best quality video image. Usually in SP mode, a regular VHS tape has a duration of (a little over) two hours.
In EP mode, the tape is recorded at half the speed of normal (SP) mode so that 4 hours of recording can "fit" on a two-hour tape. The trade-off is that you only get half the video quality that you would if the same material was recorded in SP mode. Recordings in the EP mode can be problematic to digitize and transfer and there is no way to "recover" video quality that was not recorded. We can only enhance what is in the recording.
In SLP mode the tape is recorded at one-third of the speed of SP mode with the resulting recorded image being 1/3 of the quality of SP mode. This mode allowed for up to 8 hours of recorded material on a normal 2-hour tape and is the most problematic to digitize and transfer.
The Control Track is a separate track from the video and audio tracks and it tells VCR at what speed the recording was made so that it can match that speed when it plays the tape, known as "tracking". The control track is at the edge of the physical tape and is prone to degradation over time and can be damaged by improper storage resulting in time base errors when the tape is played.
Affordable Archives uses the necessary time base corrector / frame synchronizer hardware during capture to get the best picture quality possible, however, if the control track is heavily damaged, some image degradation/distortion may still appear in your transfer.
