MP4 Still Transcoding

[castkel]

I have a few videos that are MP4 but they are still being transcoded and lowering the quality significantly how can i get it to stop transcdoing? Or at the least increase the quality of the videos

I have the default transcoding for ffmpeg i haven't touched anything

ffmpeg -ss %o -t %d -i %s -s %wx%h -v 0 -b:v %bk -maxrate %bk -bufsize 256k -flags -global_header -map 0:0 -map 0:%k -ac 2 -f mpegts -c:v libx264 -preset ultrafast -c:a aac -b:a 96k -strict -2 -threads 0 -copyts -

logs of the trancoding happening
