1. Apparatus for recording a video signal, said apparatus being operable in an intermittent mode and a continuous mode, said apparatus comprising:

  • image pick-up means for picking-up an image to produce a video signal corresponding thereto;

    compression means operable at selectively different compression ratios and having first, second, and third quantization tables for compressing said video signal to produce a compressed video signal, said compression means utilizing said first, second, and third quantization tables for operations involving a low compression ratio, a middle compression ratio and a high compression ratio, respectively, such that the first and/or second quantization tables are utilized when operating in said continuous mode to obtain a low and/or middle level of compression and the third quantization table is utilized when operating in said intermittent mode to obtain a high level of compression;

    recording means for recording the compressed video signal on a record medium; and

    control means for automatically switching the compression ratio of said compression means from the relatively high compression ratio to the relatively low compression ratio upon the occurrence of a predetermined condition.
