    1. ffmpeg -threads 8 -i D:/imagesequence/background.jpg -vf "movie='D\:/imagesequence/dpx/thumbnail.jpg' [watermark]; [in][watermark] overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/3[water];[water] drawtext=fontsize=32:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='shotName':x=(w)/2:y=(h)-50,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Notes \:':x=(w)/5:y=(h)-90,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Frame Range \:':x=(w)/5:y=(h)-130,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Lens \:':x=(w)/5:y=(h)-170,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Undistortion \:':x=(w)/5:y=(h)-210,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Image Sequence \:':x=(w)/5:y=(h)-250,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Date \:':x=(w)/5:y=(h)-290,drawtext=fontsize=28:fontcolor=White:fontfile=/Windows/Fonts/arial.ttf:text='Element Name \:':x=(w)/5:y=(h)-330,drawtext=fontfile=/Windows/Fonts/arial.ttf:text='FUTUREWORKS':x=130:y=200:fontsize=54:fontcolor=White[out]" D:\imagesequence\dpx\brn_055.0000.dpx

    2. ffmpeg -threads 8 -i D:\imagesequence\dpx\brn_055.%04d.dpx -vf "drawtext=fontfile=/Windows/Fonts/arial.ttf:text='shotcam':x=(w)/2:y=(h)-35:fontsize=24:fontcolor=Yellow,drawtext=fontfile=/Windows/Fonts/arial.ttf:text='Frame \:':x=(w)-600:y=(h)-35:fontsize=24:fontcolor=Yellow,drawtext=fontfile=/Windows/Fonts/arial.ttf:text='Focal Length \:':x=(w)-600:y=(h)-65:fontsize=24:fontcolor=Yellow" D:\imagesequence\dpx\test2.mov

    3. how do i scale an image and pass it to movie, in 1

    4. how do i make a blackscreen size that of an image say
      'D :\imagesequence\dpx\brn_055.0001.dpx' and pass it to input in 1

    5. is it possible do bother 1 and 2 in one command line ( ffmpeg ....)
      i.e. make an image from first point ( 1 ) and continue with making .mov ( of 1 image + input from point 2 )

    or in other words if it is not possible to do (1 + 2) in one command then is it possible to first execute 1 then execute 2 ( but with output from 1)
    do it

  • Revision 9f5fd31d7f : Expand UMV border to 96 pixels Ensures that the full 64 pixel border is availab

    29 avril 2013, par John Koleszar

    Changed Paths :
     Modify /vpx_scale/yv12config.h



    Expand UMV border to 96 pixels

    Ensures that the full 64 pixel border is available for prediction (need a
    minimum of
    64+INTERP_EXTEND on all sides, and 32+INTERP_EXTEND on UV). Value also must be a
    multiple of 32 to keep UV stride alignment. The smaller border was causing the
    prediction
    to read outside the frame, which can cause a mismatch.

    TODO : Get rid of this explicit border and use edge emulation instead.
