[Avid-L2] Sony FS7 AVC clips long gop variable bit rate?

 

http://www.indiecameras.com/codec-settings.html


There are a lot of variables with that camera, and AMA may have some quirks with some of the more...umm...exotic...settings.  Its been awhile since I have worked in Avid 6.x, but I remember running into some FS 7 1080p stuff that was AVC and Avid would not deal with it at all. Had to transcode it in Adobe Media Encoder.  This was fixed in MC7 or 8.x.

Recently there were a couple of FS 7 related threads one mentioned the DATA track causing issue.  Today we got one card out of several from a Sony FS-7 that didn't work with ama linking in Avid 6.5.x.  It wouldn't play in Resolve lite 9.0, I know it's old but it's what's on this system right now.  Media info showed the problem clips as AVC with a variable bit rate mode.  The working cards show up as XD Cam format but this one card is AVC.  I was thinking it might be that AVC-S consumer format that I've heard still doesn't ama into Avid, is that.                                    still true?

At any rate when I ama linked to the folder on my Avid 8.5.2 system it worked .  The PDZK-MA2 Video Format column lists the clips as XAVC Long Gop HD 50Mb/s and the PDZK-MA2 CFPS shows 59.94.  The clips fps is 23.976 so what is the PDZK-MA2 CFPS showing?  Is it just confused?  The video column lists "unsupported (HD1080P) yet it plays and transcodes. 

Is this footage possibly AVC-S media I've read about?  If so I guess this means the Avid ama plugin, which I installed a while back now handles AVC-S.  The media also works in premiere 2015.  So much for getting out early on a Friday night.  Oh well I guess I learned something but I'm just not sure what I learned.  Given all the other cards worked without issue and showed up as XDCam 422 why did this one card come in as a completely different format?  It's not some special over cranked material.  I guess it was just a different day shooting and nobody bothered to match all the other days of shooting?  Or maybe a different crew and different FS7.  Doesn't anybody check this Crap in the field.  Oh wait how would we save it in post if they didn't give us this crap.  ;-(
