Yes, I'm too lazy to look for the manual. It could be anywhere by now and you guys are always so helpful. My question is: For recording speed I know that SP stands for slow play but what does SLP stand for? Which is best to use the tape more efficiently? Thanks! Barbara
The standard playback speed is SP, and is technically the recommended video cassette playback speed. However, demand for more recording capacity has lead to the development of LP for PAL and NTSC, and EP for NTSC.
SP- Standard Playback VHS is recorded at 1.4 (PAL) or 2.2 (NTSC) metres per minute. The maximum recording time for a SP videocassette (E-300 or T-180) is typically 300 (PAL) or 180 (NTSC) minutes. The quality of SP material is higher than other speeds, because each diagonal strip of recorded video on the tape is separated by a guard band which inhibits confusion of the signals recorded on adjacent bands, allowing signals to be picked up cleanly.
LP- Long Playback VHS is recorded at 0.7 (PAL) or 1.1 (NTSC) metres per minute. The maximum recording time for a LP videocassette (E-300 or T-180) is typically 600 (PAL) or 360 (NTSC) minutes. At LP speed, sound and picture quality begins to deteriorate. This deterioration comes about because there is less space between the diagonal strips, which may actually overlap. This overlap is possible because the two special video heads used in LP mode record at different angles, and this angular difference means that confusion is not a serious problem. Obviously, however, SP is the preferred format when signals need to be clearly picked up.
EP (NTSC)- Extended Playback VHS for NTSC is recorded at 0.5 metres per minute, also known as SLP (Super Long Playback). At EP speed, sound quality is low fidelity. The maximum recording time for a single EP videocassette (T-180) is typically 540 minutes. EP is available on NTSC only because of that format's degenerate SP variant, which is faster than it needs to be given modern equipment.

If you want to keep the footage for some time, or if the subject is important to you, then you will most likely want to use the Standard Play mode. This is going to use the tape faster, about 2 hours, but you will get the BEST picture clarity.
If you use Long Play, your tape will last about 4 hours. However the image you tape will be somewhat grainy when replayed.
If you use Super Long Play, your tape will last about 6 hours. Your image will be very grainy and of the poorest quality. On the other hand, your tape will last the longest. I rarely use SLP for taping.

AND if you are going to give the tape to other people and or want to keep it beyond the life of your present machine, SP is the best for compatibility between machines. LP is not even an official speed sanctioned by JVC, but a "bonus" added to Panasonic and some other mfgs. machines.
