[Avid-L2] Re: Canon 5D ama transcode has glitches is Perian a glitch maker?

 

It doesn't look like there is any EOS app as I don't see a Canon folder in the applications folder. I did notice that the Ae's system only has QT X and no QT 7.6.6. I don't know what the Avid heirarchy is for which QT engine is implemented for Avid's ama but perhaps that might be a reason for the difference in level interpretation on the ama linked clips. It is my understanding that these canon files are coming in through the QT plugin and with no QT 7.6.6 Avid must be using QT X on the Ae system. My SNDX has QT 7.6.6 and 7.6.2 as well as QT player which I assume is the QT X. This seems like a meaningful difference in the systems.

On my SNDX 5.5.3 I only have two ama plugins installed the Red R3D (R3SDK V3.1) Ver 1.5 which I assume has no epic support because we're 5.5.3 and the Quicktime plugin V1.2. The media composer system has just the same Quicktime Plugin. When they ama link to the Canon files all start time codes are 00:00:00:00 with the exception of a group of differently named clips. The zero time code start file names starting with MVI_6442_INTY-JOE.new01 with everything after the "MVI_" changing for each clip although there will be some groups of clips that have everything the same except the ".new01, .new02 etc....) The other clips that originally transcoded with glitches have clip names like WT5A0205-INRY-JOW.new01 and these clips have normal like TOD time code ascending for example 5;05;58;17. All the clips with or without glitches on transcode have the level discrepancy in between my symphony and the mcsoft ama linked clips. I will check on the other softwares on the mc systems.
