  • ffmpeg blend to exclude the top videos background

    2 février 2016, par user2995705

    I want to blend two videos, the top video named "top.mp4" was combined with some PNG files,but the combined video’s background was black ? why ?

    then i try to overlay the top.mp4 on another video (named bottom.mp4,was capture by android camera with QUALITY_480P)

    but when I use Overlay filter i find the top.mp4 was not transparent and have a black background on the result.mp4.

    I try to use blend filter to combine top.mp4 and bottom.mp4 to exclude the top.mp4’s black background , but i don’t know how to use the blend filter.

    here is my question :
    1.is it possible to combine PNG files to a video and the video has transparent background ? and then just use overlay filter,the result.mp4 will not have a black mask under the top.mp4 ?

    2.if 1 is impossible, how to blend top.mp4 and bottom.mp4 to exclude the black background of top.mp4

    my all output log

  • unwanted bitrate reduction in MOD to mp4 conversion with ffmpeg

    18 juillet 2014, par Brian

    My Panasonic camcorder records video to a .MOD file.
    On Windows... (my linux box currently has network issues :)

    ffmpeg -i file.MOD

    yields

    bitrate: 9579 kb/s
    
video: mpeg2video yuv 420p 704x480 [SAR 10:11 DAR 4:3] 
    
29:97 fps, 29.97 tbr, 90k tbn, 59.94 tbc

    I tried

    ffmpeg -loglevel verbose -i file.MOD file.mp4
    
ffmpeg -loglevel verbose -i file.MOD -qscale 0 file.mp4
    
ffmpeg -loglevel verbose -i file.MOD -qscale 1 file.mp4

    Each of these yields the same bitrate of 2604 and a video codec of h264 (High).
    My original file was 22,786 KB and the new files are each 6,217 KB.

    My goal/purpose is for lossless conversion of the .MOD files for video editing, probably using blender.

    So my big question is "How do I do lossless video conversion of .MOD files using ffmpeg to a format that blender and other common video editing tools can work with ?"

    But for educational purposes (and posterity) I am also curious why the bitrate is being reduced by the conversions above and why there is no difference when using the -qscale argument.

  • Converting avi to mp4 (use ffmpeg library) is very slow

    7 décembre 2012, par yAnTar

    I have task - convert any video from user to mp4 format.
    I use command

    ffmpeg -i $file -vcodec libx264 -vpre ultrafast -bt 500k -acodec libfaac -ab 56k -ac 2 -s 480x320 $outputFileMp4

    I try to change options bitrate, dimensions, but spped of converting is slow - 3 mbytes convert arround 90 seconds.

    If i convert avi to flv - no problem.
