Comment (by Gregory Beauregard):

 Here's a reproducer that doesn't require a download of the "seek" kind:

 Generate test input:
 {{{
 ffmpeg -report -f lavfi -i
 testsrc=duration=60:size=1920x1080:rate=30,format=yuv420p -f lavfi -i
 sine=frequency=440:duration=60:sample_rate=44100:b=4 -pix_fmt yuv420p -c:v
 libx264 -b:v 1000k -profile:v high -preset veryfast -c:a libopus -b:a 128k
 -y "freezeinput.mkv"
 }}}

 Encode that freezes:
 {{{
 ffmpeg -ss 00:00:30 -re -i freezeinput.mkv -c:v libx264 -preset superfast
 -b:v 500k -c:a copy -y initfreeze2.mkv
 }}}
