  • How to ffmpeg resize 2.7k DJI Phantom Standard video to 1080p good quality ?

    23 mai 2016, par augre

    ffmpeg -i :

    Duration: 00:01:59.99, start: 0.000000, bitrate: 39988 kb/s
    
Stream #0:0(eng): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 2704x1520 [SAR 1:1 DAR 169:95], 39984 kb/s, 29.97 fps, 29.97 tbr, 30k tbn, 59.94 tbc (default)

    I used :

    ffmpeg -i DJI_0002.MOV -vf scale=1920:1080 DJI_0002FullHD.MOV

    But the output quality is much worse than it should be.

    How to improve the quality ?

  • Is there a good list of mp4 supported resolutions and a way to have ffmpeg calculate the width after modifying by set height ratio ?

    16 novembre 2016, par Nova

    After finding the resolution was the source of all my webm to mp4 codec conversion errors on my android. I came across another problem. To break down my question :

    Is there a good list of mp4 resolutions that are supported on most devices ? I know they go by p from certain height value for them to work. 720p / ???x720 for example.

    Also is there an easier way to calculate the width based from the height change while keeping the ratio ?

    ffmpeg -i old.webm -t 00:00:03 -s 320x240 new.mp4

    I currently use the -s setting perimeter from my testing example. Any help would be appreciated.

  • Revision 360c80cfb9 : Use fast HEX search in real time mode In good quality mode motion search, the b

    15 février 2014, par Yunqing Wang

    Changed Paths :
     Modify /vp9/encoder/vp9_mcomp.c


     Modify /vp9/encoder/vp9_mcomp.h


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h


     Modify /vp9/encoder/vp9_rdopt.c



    Use fast HEX search in real time mode

    In good quality mode motion search, the best matches are normally
    found after searching in a large area. In real time mode, to make
    encoding fast, a center-biased fast HEX search is used, which
    converges quickly most of the time. A 4-point diamond search is
    also carried out as the following refining search, which gives more
    precise results, and maintains good motion search quality.

    At speed 5, the borg test on rtc set showed an overall PSNR loss of
    0.936%. The encoding speed gain is 4% - 5%.
