To consistently achieve the best results with your X4, use UHS-I microSD cards with a V30 or above speed class and exFAT format. Using incompatible microSD cards may cause issues while recording, and footage may be damaged or not usable.
Notice: Do not use UHS-II/UHS-III microSD/TF cards, or memory cards larger than 1TB. These cards are not compatible and may cause issues while recording.

*Since the SD card is used not only for storing footage but also needs to reserve some space for recording cache, approximately 1-2GB is needed. Therefore, a discrepancy of 1-2GB from the data in the table is within the normal range.
