Unfortunately, in real-world conditions, Beta IMX videotape would not hold up to repeated shuttling, pausing on one spot, reverse running, etc. Nowadays, as a file format, IMX is amazingly robust.
I now say:
Oops, I just noticed that I've confused Sony's IMX format with their older SX format. SX was the dog. IMX seems to have held up pretty well, even to this day. SX . . . not so much. I incorrectly attributed IMX as being Long-GOP. It is not. SX however is Long-GOP.
This is why it pays to refresh your memory before posting. ;)
