Nothing unexpected.
Thanks for confirming. IIRC I had trouble with (some) older x264 versions and no-scenecut and had therefore worked with -force_key_frames for a while. But I cannot reproduce the problem with current x264, so I switched to x264opts with no-scenecut. -- theatre - books - texts - movies Black Trash Productions at home: http://www.blacktrash.org Black Trash Productions on Facebook: http://www.facebook.com/blacktrashproductions _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
