Again rather than spotting the triple, I noticed that there couldn't be another 15 pair in block 6 so that meant the 1 and 5 had to go in row 7 of column 7. This was at around 5 minutes in your video. This then gave me the 3 in the bottom right corner. By simple counting the 9 could be placed in column 2 row 9. The puzzle fell apart quickly from there as this unwound the 79 pair in block 8 and in addition placed the 9 in the top left corner .
Not very difficult, but quite good fun (94 = row 9 column 4):
94, 75, 86, 45, 26,
54, 44, 16, 14, 24,
34, 28, 49, 59, 41 (UR possible at this point),
27, 35, 88 (hidden triple in box 7; or UR, boxes 6 and 9),
47, 48, 77, 99, 92 (not forgetting the triple),
11, 21, 15, 25, 13,
12, 73, 22, 23, 81,
91, 83, 98, 89, 78,
37, 39, 67, 57, 96,
76, 69, 51, 61, 56,
66, 58, 68, 52, 53,
31, 33, 62, 71, 72.
