Many thanks to all for the replies. My issue is that the data are from an old 8mm (1940) that I scanned. Between bad filming, film shrinkage and less than acceptable frame registration the zooming would be so significant that I'll throw away most of the frames !! I will play with the options and will come back to this one. > As an alternative to the deshake filter you can use vid.stab[2][3] which > is intregated with two filters in ffmpeg (if compiled in the right way). > It only supports 2-pass-encoding in ffmpeg.

As far as i know you have to "zoom in" to get rid of the artifacts at the borders, as Bouke already mentioned. The filter documentation[1] actually mentions an option "edge" which sounds like what you want to change. Try different values for that. Maybe "original" is what you're looking for. As an alternative to the deshake filter you can use vid.stab[2][3] which is intregated with two filters in ffmpeg (if compiled in the right way). It only supports 2-pass-encoding in ffmpeg. You also get some "wobble" artifacts at the border, but it isn't that bad most often. You might still want to crop a bit at the edges.

Please provide the command line you tested together with the complete, uncut console output. Just a hunch, to stabilize you move the frame within is boundaries. Crop filter after the deshake may be the answer...

[FFmpeg-user] stabilisation
Hi all New on this list. Apologies it the question is recurrent but I did not find an answer. Here we go when using -vf "deshake" a black frame is coming separating the original frame from the "interpolated" pixels along the boders. More like a line than a frame actually ! Is there a way I can turn off these black lines ? Many thanks Edouard ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
