I have a project with XAVC media:
XAVC Intra 100 (HD1080p)
and from a Sony F-55:
XAVC Intra QFHD
I updated my Avid to Ver. 8.3.1 and installed the new Sony AMA plugin Ver. 3.4. Everything is working but I have a few questions that the help file doesn't quite cover.
I found that Avid was automatically applying a lot when I ama'd to the folder containing the media. When I initially ama to the clips they get "Sony_S3C 1. SLog3-SG3.Cine to LC-709" as the Color Transformation in the bin. However if I go into the source settings on a clip and delete that in the Color Space upper section of the Set Source Color Encoding I can see other choices for Color space in a pull down menu but I don't see a way to add them. The add button at the bottom only adds what is in the lower pulldown menu. I found it I delete the automatic Color Space the only way to read it is to hit the auto button. Is this the only way to get the automatic color space reapplied? Given the pulldown choices I would think I'm capable of choosing a different color space and applying it but I don't see a way to do that. As I said the add button at the bottom only seems to apply to the bottom pulldown menu. I'm fine with the auto choice for color space on this project but leads me to another observation.
I found that the when I first ama the clips into a bin the Color Transform is "Sony_S3C 1. SLog3-SG3.Cine to LC-709". If I delete that and then use the auto button to reapply the color transform now reads, "From Sony SGamut3.Cine (SLog3 gamma) to REC709." From what I see on my scope it is doing the same thing. It's as if there are conflicting naming conventions buried in the metadata but I'm not really sure. Has anybody seen this behavior?
Now I'm transcoding from the ama links to DNX-175X and I have checked to bake in the LUT and FrameFlex because the project will ultimately be done in Avid Ver. 6.5.x latest version. I noticed if I don't check the frame flex bake in box the resulting media is 1920x1090 but the frame flex deminsions are the 4K original numbers of 3840x2160. I think I understand what the intentions are here but I want to confirm. I assume that if the offline was being done on Ver. 7 or later that supports frame flex even though the raster is now truely 1920x1080 if frame flex was used in offline it's numbers would be based on the raw medias raster of 3840x2160 and the scaling would be correct if in online we went back to the ama original media. Is that the gist?
I must say I'm liking the background transcode on this which is allowing me to check other bins and navigate Avid while the transcodes are maxing all 24 cores in Activity Monitor. It's really helpful while I getting up to speed on Ver. 8. Now I initiated the background transcode by checking the box in the Transcode dialogue box and I can see the progress in the background Queue. I recall that there was a web browser interface for the DMF folders to watch the progress on those. I haven't played with DMF yet but the checkbox in transcode dialogue was very easy. What would happen if I quit Avid with the background transcodes going? Are they different the the DMF which would run stand alone IIRC?
