I am very frustrated to with the poor result of importing my Panasonic HDC-TM900 1080/60p footage. With the rewrapped to mov files i got the same green flickering or the weird jumpy artefacts. More weird: After restarting FCPX the green flicker could now be an artefact or wise versa. In 60p footage there is a green frame on every frame 23/24 and 53/54. Or on frame 22/23 and 52/53, which means every 30 frames there are to defect frames.
After converting the rewrapped files into ProRes, the movie seems to be red&black. No more other colors. If I convert the originals MTS files with FCPX into ProRes I have the same jumping artefacts - but now hardcoded in the ProRes files - as I import the rewrapped files directly. But at this point it shows "only" the artefacts, not the green frames blinking.
Otherwise iMovie plays and edit the rewrapped files and the Prores files just fine. No artefacts, no green frame blinking.
I have rewrapped the files with the current command line version of ffmeg v0.8. The pcm_s16be preserves the 5.1 audio channels, which got lost in my test with ClipWrap:
ffmpeg -i inputfile.mts -vcodec copy -acodec pcm_s16be outputfile.mov
With the rewrapped file I got many Console messages like:
Final Cut Pro[1660] -[FFCodecOperation main]: Error -12350 from VTDecompressionSessionDecodeFrame for sb 0x134700d70, refCon 0x123319ae0 (dts=10.527183(631631/60000), pts=10.527183(631631/60000)) (attachments array follows)
and
Final Cut Pro[1660] FFImageRepFigSchedFrame - decompression error (no image) err=-12350
and
Final Cut Pro[1660] FigProvider - got back a nil CVImageBufferRef in decompressionCallback when it wanted the output, how did that happen (status = -12350, flags=0x0)
Perhaps this could be caused due to the updated Open CL components and graphics drivers in Mac OS X 10.6.8. As FCPX uses much more of the Open CL acceleration possibilities, there is possibly a bug in the H.264 decoding components.
Maybe the announced Panasonic AVCHD import filter for FCPX comes soon this summer and helps to get rid of that problem. Maybe Apple will publish an very neccessary update sooner. Let's cross fingers.
This is even more worse, as this green flicker / artefacts problem is not just shown in movie preview. It is still existing in any edited and exported footage. For me, this is not acceptable.
