  • ffmpeg - Dynamic letters and random position watermark to video ?

    2 avril 2016, par sekmo

    I am making an online course, and to avoid piracy distribution I thought to put watermarks on the videos (including personal user information) so it cannot upload to sharing websites. Now the hard part : I would move the watermark during the video, in 3/4 random positions, every 30 seconds.
    It is possibile with ffmpeg ?

  • How to get iOS App Preview video bitrate in range

    29 avril 2019, par JKaz

    Creating new App Previews for App Store Connect has always been difficult. Time to do it again (new app version) and running into same issue without resolution this time.

    Making the video is easy enough, recording it with Quicktime and either a connected device or through Simulator (and the xcrun simctl io booted recordVideo <filename>.<file extension="extension"></file></filename> Terminal command).

    I can open that in iMovie, create a new App Preview, and export/share the preview with proper size, length, frame rate per Apple specs. But the bit rate is always too low ( 4 mbps) and it’s required to be 10-12 mbps (and I’ve had video reject be/c of that). In the past I could always make some change to the .mp4, in conjunction with something like ffmpeg -i ~/appVideo.mp4 -b:v 11M ~/appPreview.mp4 to get the file into the target range, but that’s not helping today, and neither is Developer Tech Support.

    Apple’s documentation says :

    To export the final video, click Share in the toolbar, then choose App
    Preview. The export settings are automatically configured to meet App
    Store requirements. iMovie exports the final video at the correct
    resolution based on the device from which your clips were captured.

    I’ve done that and more, and bit rate is still out of range (every other attribute is in spec). I’ve tried the recommendations from a bunch of other threads here for http://video.online-convert.com/convert-to-mp4 and others, and none seem to do the trick. Am I missing something obvious re bitrate ? Is it this hard for everyone ?

    Thank you.
