Re: [FFmpeg-trac] #1430(avfilter:new): More efficient deshake filter
#1430: More efficient deshake filter -+ Reporter: ubitux |Owner: Type: enhancement | Status: new Priority: wish |Component: avfilter Version: unspecified | Resolution: Keywords: deshake | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0| -+ Comment (by cehoyos): Replying to [comment:9 jbvsmo]: Replying to [comment:8 cehoyos]: Works even better with -cpuflags -sse2 -vf deshake=rx=63:ry=64 But it is not even close from what the proposed link shows. Sorry, which link do you mean? Also, this configuration makes it very slow to be used on realtime. A good deshake filter should add the possibility to crop the image instead of filling it with surrounding pixels. Try adding crop=600:400 after the deshake filter to see a better result. Of course, I don't understand the above argument... This will crop in the middle while the deshake filter could manage to crop in the right places. --- BTW, in the ffmpeg-devel list, there's a proposal to include a binding for vid.stab (https://github.com/georgmartius/vid.stab and http://public.hronopik.de/vid.stab/) library. The results seems to be superior. Why can't the library be included directly in ffmpeg? I'd like to know the answer as well, please ask the developer! -- Ticket URL: https://ffmpeg.org/trac/ffmpeg/ticket/1430#comment:10 FFmpeg http://ffmpeg.org FFmpeg issue tracker ___ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac

Using -cpuflags -sse2 -vf 'deshake=rx=63:ry=64, crop=600:400' The crop filter will be in the middle of the video, but it may not be the optimal place to crop.

An interesting de-shake filter article:
http://googleresearch.blogspot.in/2012/05/video-stabilization-on-
youtube.html
Our deshake filter isn't very efficient with the provided sample (at least
with the default settings)
{{{
clive -f best 'http://www.youtube.com/watch?v=627MqC6E5Yo'
}}}
{{{
ffplay -vf deshake 'Sam and Cocoa shaky original.webm'
}}}
It would be nice to improve the filter to handle such sample.
