I was testing some MLT changes with AVCHD when I noticed the video (but not audio) of rendered output was playing twice as fast as expected. I found that when you have "Drop B frames on H.264" enabled in Settings, it is putting non-empty (bidir) skip_frame and skip_loop_filter elements in the generated XML.Turning that option off fixes it. These should not be used when rendering - only the preview monitors. This might explain why some people are reporting the rendered output does not have the same cuts as they put on the timeline. -- +-DRD-+ |

See this related bug: http://www.kdenlive.org/mantis/view.php?id=1330 skip_frame=bidir is affecting my video playout speed in melt too - at least on my mac. I am still pondering all of the options and looking into further, but you might want to consider something drastic, last minute, such as hiding that option and ignoring any saved setting from previous version. -- +-DRD-+ |

Thanks. I just disabled the "Drop B frame" feature, that did set the "skip_loop_filter" and "skip_frame" settings from Kdenlive. They will not be added anymore by Kdenlive, hope it will help. However, if some users created a rendering script, they will need to recreate it, because it might still be in the script files. regards jb |
