Senior developer, I don't quite understand what you mean? Does it mean that my D drive does not have LOGO watermark text? Can you give me an example? Be more detailed, thank you infinitely

I have tried to switch to the "advanced" mode, put something like "zscale = transfer = linear, tonemap = reinhard, zscale = transfer = bt709, format = yuv420p" into the lavfi field, set the depth = 8 bits,
But every time the effect appears, it is displayed incorrectly and cannot be converted at all. I would be very grateful for answers.
The following is the error log content.
