1-inch machines were considerably smaller and more reliable than preceding two-inch versions and were seen by operators as a major technological breakthrough. Usage ġ-inch tape gained numerous uses in television production including outside broadcasts where it was used for instant replays and creating programme titles.

Type C VTRs may have flying video erase heads mounted on the drum, allowing for individual frames to be erased. PAL Type C VTRs may have higher writing speeds to achieve higher bandwidth given PAL's 8 MHz bandwidth vs NTSC's 6 MHz. The tape is almost completely wrapped around the drum of the VTR in what is known as an alpha wrap. Type C VTRs can record a single complete video frame in a single revolution of the drum, using a single video head, which made the format useful in computer animation and allowed for stills without frame stores or buffers. It had approximately 300 (scan or vertical) lines of resolution, and a bandwidth of 5 MHz, with recording being done with the heads moving across the tape at (a writing speed of) 1,008 inches per second. Because television was broadcast as a composite signal, there was no real downside to Type C in television broadcasting and distribution. Both analog component formats were notoriously fussy and trouble-prone, so in practice Type C gave a stable, more reliable picture than the broadcast quality analog cassette-based videotape formats. 1–inch Type C VTRs required much less maintenance and used less power and space than did 2–inch machines.ġ–inch Type C records composite video at a very high video quality that was superior to contemporary color-under formats such as U-matic, and of comparable quality to analog component video formats like Betacam and MII. 2–inch quadruplex videotape machines lacked these capabilities, due to the segmented manner in which it recorded video tracks onto the magnetic tape. 1–inch Type C is capable of "trick-play" functions such as still, shuttle, and variable-speed playback, including slow motion. Compared to Quad, Type C had a smaller size, comparative ease of operation, and slightly higher video quality.
