[FFmpeg-user] non-zero start after transcoding

> I usually disable -avoid_negative_ts

thank you, Nicolas, for your suggestion, however if i add this option:

ffmpeg -t 00:00:10 -i input/BM_1_2014-06-28_1221_C0000.mov -avoid_negative_ts 0 -vcodec libx264 -pix_fmt yuv420p -vlevel 4.1 -refs 4 -preset slow -acodec ac3 -ac 1 -ab 128k 0.mkv

i'm getting closer to 0, but the start is still non-zero:

Duration: 00:00:10.01, start: 0.005000, bitrate: 1512 kb/s
