I would recomend ffdshow encode (lossless huffyuv is perfect for realtime video capture, also ffmpeg own codec ffv1 can be selected in ffdshow).
Later this can be encoded with padding to 1280x720 with help of the ffmpeg.

@set x264opts="level=4:qp=16:ipratio=2:colorprim=bt470bg:transfer=bt470bg:colormatrix=bt470bg:fullrange=off:overscan=show:pic-struct:force-cfr=1:aud=1:threads=auto"
@ffmpeg -i %1 -c:v libx264 -preset ultrafast -tune zerolatency -profile:v high -x264opts %x264opts% -x264-params %x264opts% -vf "pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=sar=1/1" -af "aresample=resampler=soxr:osr=44100:cutoff=0.95" -strict experimental -c:a aac -b:a 320k -ac 2 -shortest -movflags faststart %1_.mp4
