[error code:]

I used the code from the tutorial

https://tinycircuits.com/blogs/learn/tsv-video-converter-tutorial

error code:

Arduino: 1.8.2 (Windows 10), Board: "Arduino/Genuino Uno"

C:\Users\Schiff\AppData\Local\Temp\Temp2_TS+TSV_Sketch.zip\TinyScreenVideoAudioSimple\TinyScreenVideoAudioSimple.ino:12:19: fatal error: SdFat.h: No such file or directory

#include "SdFat.h"

                   ^

compilation terminated.

exit status 1
Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences

Add the SdFat library.  It can be downloaded in the 1.8.5 IDE using the Library Manager.  It has the missing header you are looking for.
