Yes, the Canon PowerShot V1 is compatible with the SanDisk Extreme microSDXC UHS-I 128GB.
Canon PowerShot V1 has a full-size SD card slot. SanDisk Extreme microSDXC UHS-I 128GB (real write speed 130 MB/s, V30-class) fits via the bundled microSD-to-SD adapter and clears every mode except the camera's 4K-cropped 10-bit HDR PQ IPB Standard mode, which the camera's own reference page states requires Video Speed Class V60 or higher -- this V30-class card falls short only for that specific mode.
Conditions for compatibility
requires the bundled microSD-to-SD adapter (included with the card); does not support the 4K-cropped 10-bit HDR PQ IPB Standard mode (requires V60, this card is V30-class) -- every other mode (UHS Speed Class 3 or lower) works normally.
Limitation
Cannot record 4K-cropped 10-bit HDR PQ video -- requires a V60-rated card; this card is V30-class. All other recording modes work normally.
“4K (cropped) 59.94 50.00 IPB (Standard) UHS Speed Class 3 or higher Video Speed Class V60 or higher”
