  • App review video ( App Store )

    23 août 2016, par Arnold Mapps

    I want to convert a video recorded with Quick Time ( resolution 750*1334 ) to 1080*1920.
    Apple only accept resolution 1080*1920p for iphone6PLUS for App review video.

    My license key with final cut pro X has expired and
    ffmpeg -i AppPreviewIphone6.mp4 -vf scale=1080:1920 AppPreviewIphone6PLUS.mp4 give me a resolution of 1079*1920 instead 1080*1920

    Have you an idea what software I can use to change video resolution ?

  • ffmpeg : jpeg-images with different resolution -> video sequence ; using padding instead of scaling [on hold]

    3 septembre 2013, par user2742503

    I am currently struggling with the following problem using ffmpeg : I have a bunch of jpg-files with different resolution (say, one is 320x240, one is 800x600 etc) and want to create an avi-file using mjpeg as a video codec withn a output-video resolution of 800x600. The images itself should not be scaled in any way, that means : What I want to achieve is to just place the image in the center and fill the remaining space with white or black instead of scaling up the smaller images to the target resolution.

    So far I have used

    ffmpeg -f image2 -r 1 -i image_%04d.jpg -vcodec mjpeg -s 1920x1080 -qscale 2 -r 25 output2.avi

    or

    ffmpeg -f image2 -r 1 -i image_%04d.jpg -vcodec mjpeg -vf scale=1920:1080 -qscale 2 -r 25 output2.avi

    in case of scaling to HD resolution.

    Would be very thankful for any support on that !

    Thank you in advance !

  • avfilter/vf_psnr : Prevent integer overflow.

    21 septembre 2013, par Neil Birkbeck
    avfilter/vf_psnr : Prevent integer overflow.

    The 32-bit integer accumulator in MSE computation can overflow for 8-bit frame data.
    
(e.g., for 1080p white frame compared to a black frame can give sum of 255*255*1080*1920 > 2^32).
