ffmpeg is there any way to trim a video and hardcore subtitle at once?

[linhoct11]

I'm still new at this. I have to re-encode a video twice so the quality may worsen.

Here are 2 processes:

ffmpeg -i NA3.mp4 -vf "ass=NA3.ass"  -c:v libx264 -crf 15 -c:a copy outputC.mp4

ffmpeg -i outputC.mp4 -ss 0:00:00.000 -to 3:04:50.839 -c:v libx264 -crf 15 -c:a aac outputC-.mp4

Is there any way to join these 2 command so it only encodes once?

Thank you
