When you record on VHS—or play a tape recorded by someone else—the recording speed dramatically affects picture and sound quality.
The Three Recording Speeds
SP (Standard Play)
Fastest speed, highest quality.
• Tape speed: 1.31 inches per second
• Recording time: 2 hours on T-120
• Best possible VHS quality
Always use SP for important recordings.
LP (Long Play)
Half the speed of SP.
• Recording time: 4 hours on T-120
• Noticeably reduced quality, more noise
• Still watchable for casual content
EP/SLP (Extended Play)
One-third SP speed.
• Recording time: 6 hours on T-120
• Significantly degraded quality
• Common tracking problems
• Only use when recording time is priority
How Speed Affects Quality
At slower speeds:
• Less tape surface per frame of video
• Narrower tracks (harder to read accurately)
• More crosstalk between adjacent tracks
• Linear audio quality degrades significantly
Compatibility Issues
EP tapes recorded on one VCR may not play well on a different VCR. The narrow tracks are sensitive to mechanical differences between machines.
SP recordings are much more compatible across VCRs.
Commercial Tapes
All commercially prerecorded VHS (movies, etc.) are recorded in SP mode. If a commercial tape has quality problems, it's tape age or damage—not recording speed.
Summary
SP: Best quality, best compatibility. Use for anything you want to keep.
LP: Acceptable compromise for non-critical content.
EP: Maximum time at significant quality cost. Avoid unless necessary.
