I installed a trial version of Movie Edit Pro2013 12.0.0.32, created a new project and imported a .m2ts clip 1920x1080 50p from a Sony CX730 camcorder. Project settings match audio and video properites of the clip. Clip length is 888 frames. No editing applied. Rendered clip with smart rendering and copy enabled, verified that smart info promised copy with no recompression. Rendered clip had a length of 864 frames. 24 frames at the end of the clip were trimmed. Replaced original clip with rendered one. Smart-rendered again, second resulting clip had a length of 840 frames, 24 frames at the end were lost in space again. Tested with several other clips, always observed this strange behavior. Can anybody confirm this bug?
