Hi @lori357 ,
What is the "speed" classification of the memory card in the camcorder?
Class 10 SD cards work better with video than Class 4 cards for example.
The [link|https://www.sdcard.org/developers/sd-standard-overview/speed-class/|speed class information] is on the card label.
The [link|https://www.sony.com/electronics/support/res/manuals/4566/45662771M.pdf|user manual] says to use a Class 10 SD card if using for 4K video recording - see p.19
Has it worked OK before using the same memory card?
