Why don't my videos save when I use the FS81?

If you find you're scanning your 8mm or Super8 film and the videos are not saving on the SD card, you will need to check the capacity and speed of the SD card. You may need an SD card with a higher capacity

FS81 is compatible with SD cards that are a maximum of 32GB and class 4 and above. Videos will not save on larger SD cards and may appear jittery on cards lower than class 4.
