Watermark not displaying in MKV formatrt

I was trying to export in mkv trying to put ffmpeg command for water mark, water mark not displaying but the same way avi format water mark is displaying, my command follows as

$" -i {“sourcevideopath”} -i {path} - filter_complex \text\-c-v h264_nvenc -maxrate 4M -bufsize 8M -c: a copy {temppath}

as the error i have found codec could not found , since there is no parameter for passing codec in mkv format and the same avi format i am passing the codec parameter. I have tried many things to change in the command but watermark wasnt displayed. Please do let me know to tackle this … thanks.

In general the purpose of MKV export is to provide a very quick export and because of this the MKV Export is always the unaltered video data as supplied by the camera originally, this explains also how you cannot set a codec on this form of export. I am afraid that for your purpose here the MKV Export will not fit.

Hi Bo, can you please confirm this is still the case with the latest versions of XProtect?

Thanks.

MKV Export is unaltered video, no change
