[FFmpeg-user] 'image trails'

Tue Apr 7 18:34:34 EEST 2020

I hope that the attached video is allowed and that it survives.

                                   > select=/*n+1%10==3*/ >
IN --> telecine=pattern=5 > split > select=/*n+1%10==8*/ > mix > OUT
                                   > select=/  *else*   / >

The attached video has 'image trails'. Any ideas why that is?

Regards,
Mark.
