    Hi there!
    While testing resizing videos filmed with a Samsung NX3000 camera with ffmpeg into different smaller sizes I just tested to use the same video size as the actual original video to see what would happen and got an incredible reduction of the video size.

    The original 20 minute video was 1.4 gig . This size for 20 minute videos is always the same. The new video with apparently the exact same codec data as shown by VLC, see pictures, is only 244 MB (0.244gig).
    I haven't found any information about something like this in a fast search on the web.

    Video data of the original video:
    1280x720 | H264 - MPEG-4 AVC (part10)(AVC1) 29.970030 fps planar 4:2:0 YUV Code: MPEG AAC Audio (mp4a) stereo 44100 khhz 32bits| 1.4gig

    ffmpeg command used:
    ffmpeg -i videoname.mp4 -s 1280x720 -movflags +faststart -c:a copy 01020339_1280x720.mp4

    Resizing to other sizes resulted in the following:
    852x480 | -> 105 Gig
    960x540 | -> 126 Gig
    1280x720 | -> 244 Gig

    Any idea why this could be?
    How could I find out if there was a quality reduction?
    On this laptop screen I can't see any difference.
