I just tried minterpolate=fps=250:mc_mode=aobmc:me=epzs and did have some artefacts in one of my slowmo samples but overall the quality is very, very nice! If you're interested in more samples or in more testing, let me know. Is the command line I used the one best for reducing artefacts or are there options known to be better in terms of artefact reduction? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
