Actually this thread describes the same problem that I have:
I export from PPro CS6 timeline to MXF OP1a, with the IMX 30 PAL or IMX 50 PAL setting.
Levels and gamut comes out shifted so that it is clearly visible and gamut goes sporadically out of legal range.
If I export to Quicktime ProRes from the same sequence, everything is fine.
I am running PPro 6.0.2. on Mountain Lion 10.8.2.
Maybe someone from Adobe´s side can help!?
just wanted to add:
This happens regardless of the footage I edit. I tried with:
- .avi uncompressed, PAL
- .m2p, PAL
Sequences have been created with "create seq. from clip".
Actually if I export IMX in QT container, there also is a shift.
Still nobody an idea about this?
I created color bars, exported out as IMX 50, then reimported into PP. Looking at both the original bars and those exported, there is a very, very slight shift in levels such that the export is now at about 101 IRE, instead of the original 100. There were also noticeabe differences between the two on the vectorscope.
My guess is this may be an unavoidable artifact of MPEG encoding, as exporting to lossless did not show the same shifts.
Hehe... I've reported this problem in feb 2011.
Gues what? No answer. Like I see this bug is still in CS6.
PS: I use ffmbc to produce IMX SD PAL MXF.
Thank You, Simon.
I sent bug report today. We have a large number of SC6 Production Premium, and we have moving all production workflow of Latvian TV to CS6.
Similar bug have Sony Vegas Pro v12 when exporting to HD mpeg-2 for BluRay, and SCS acknowledged that the problem exists:
We also reproduced same problem on different hardware platforms. Bad thing that we have many customers that looking on Adobe Premiere CS6 as primary NLE system in facility and one of major disicion points is that they want to choose it cause of ability to export in MXF OP1a IMX and they want to have IMX as theirs main production format. And know looks that we have to stop everything cause of disability of Adobe to fix their problems for 3 years as i understand bobas. Somekind of cheating. I don't belive that support (especially R&D) is checking this forum cause there is no any "Bug confirmed" messages. And this is shame, spending huge amount of money for Adobe products and no support, cause last time i was contacting it, regarding IMX problem, answer was check this page for "phone contacts" just amazing.
I see this same problem on my Windows system when exporting from After Effects (CS6 and CC). Exporting an IMX OP1a IMX 50 causes a rather dramtic shift in colour, particularly in the red and green channels. As this is the format that is becoming the standard in the UK for digital delivery, would anyone from Adobe care to comment?
If Adobe developers within multiple versions are unable to respond to a number of bug reports and correcting just one of his errors, there is not worth spending money on Adobe products.
