Just curious but why ai12 when it's XAVC? Isn't aivx the correct fourCC in this case? -- When i rewrap using -vtag aivx ffmpeg -i AVC100CBG_1920_1080_H422IP.MXF -map 0:0 -map 0:1 -map 0:2 -c copy -vtag aivx FFMPEG.MOV Then Quicktime ( only tested with 7 ) can't play the file, furter more FCPX-10.1.3 uses the same vtag ai12 when rewrapping this to an original AVC-Intra format in mov. The logic I found checking what FCPX uses to rewrap to mov but not completly tested all possible combinations - ai12 is used for HD 25, 29,97 - ai13 is used for HD 23.98 - aivx is used for 4K formats If i use -vtag aivx in ffmpeg then playing in Quicktime won't work but cmd-I shows the correct info but the player window remains green. Mplayer will playback video. FFmbc refuses to use -vtag aivx but when using -vtag ai12 produces a 4K file that plays in quicktime the cmd-I info is not consistend with the video as would be expected ( wrong frame rate). Trying same thing in FFMPEG but this won't work for an AVC_4096_2160_H422IP@L52 50FPS file. A AVC_4096_2160_H422IP@L51 25FPS -vtag ai12 plays when rewrapped bij FFMBC and FFMPEG in Quicktime-7, Quicktime PlayerX prompts an error " operation could not be completed ". There are a lot more options to investigate but the initial conclusion is that everything above HD frame size has problems in just rewrapping to quickitme mov. FFmbc-7.1 seems to produce a more tolerant version but is not prefect either. Om my test system i have FCPX installed and the Sony XAVC plugin. Any Suggestion to get this fixed are more then welcome.
