[FFmpeg-user] ffmpeg encoding in h264 instead of raw video

I'm trying to take a raw video file and raw audio and remux them together
still as raw. I don't want any compression. I'm doing something wrong but
not sure what. It ends up making h264 even though i never asked for it. I
got this command from a tutorial on the web on how to concat multiple
videos together with ffmpeg. This is the last step. Any help is
appreciated. Thanks
Here is the input:

ffmpeg -f u16le -acodec pcm_s16le -ac 2 -ar 48000 -i /all_a1 -f
yuv4mpegpipe -vcodec rawvideo -i /all_v1 -strict -2 /all.mov

Here is the output:
