Question

Shake Reduction causes black borders.

When I apply Shake Reduction (Detailed) to my mp4 video clip it and export or render it then it has black borders around it and doesn't match my other clips that are full view in 1920 x 1080 format. The format numbers are the same so it must be adding a black border rather than resizing it to match the other clips without borders. I can understand that to eliminate the shake it needs to crop but I need it to then enlarge back to original size with no black border. Am I doing something wrong? Thanks.

    Share Reduction can help but it does not do miracles.

     

    I have recently used it (APE 2021 on WIN10) to smooth footage from a cheap HD action cam

    that did NOT have any built-in stabilisation for some underwater sequences.  I set the

    "Crop Vs Smooth"  to 12% as recommended on page 123 of Steve Grisetti's Guide to APE 2021

    and the results looked pretty good:  https://www.youtube.com/watch?v=Taowg12k35U

    Under water sequences start at 1:00.

    That looks pretty good to me. I'll experiment with different Crop Vs Smooth settings.

    If you go into Applied Effects you can lower the amount of Shake Reduction and that should fix it. I usually find its default is higher than necessary and I set mine for closer to 15%.

    If that doesn't do it, can you post a screen capture showing the black frame? I've never seen black borders around a Shake Reduction video.

    When I did a 15% crop vs smooth rather than the default 50% it added less of a black border but it's still there. I left the smoothness setting at 50%. Here is one screenshot without shake reduction and one with.

    Go to the program's Edit menu and tell us what appears on the General page under Project Settings.

     

    Then open the video you're editing in the free download MediaInfo. In MediaInfo, set View to Text and then copy the complete report it generates and paste it to this forum.
