RED in MC5 im confused
Hi,
I have some RED footage and i want to know how to transcode it. In MC5 i have been told to set R3D Source Quality to Quarter. Why is this? Also what is all this i read about relinking to the original meta data after i have completed the edit??? Is this to reserve the quality??
Please could somebody shine some light on this for me, it would be very very well recieved.
thanks
Ben

So you just want to transcode to your final resolution? That would speed up the process if you don’t have a lot of footage. Select 1/2 debayer premium and either DNxHD 115 or 175 and transcode away.

hi, thanks for the reply.
Im not sure i understand what you mean please could you elaborate? I still dont understand what re linking is and what it is for?
Basically its a 10 minute film but i understand you have to transcode first to make editing smoother and the re link the footage. Is this the case? Also why is this reqiured? -
Hi Ben,
the whole relinking topic when using RED material refers to the possibility to colour grade the material in a grading system after you finished your edit. As RED records raw files you don`t have a final picture when you open the RED files. If you don`t intend to do a grade outside of your Avid then you don`t need to think about relinking. The problem with RED material is that you as an editor have to do the baslight grading when you open the files in your avid. I`m not in front of my Avid but after opening the files via AMA you can then interpret the footage by clicking on the clip in your AMA bin and then open the clip menu. I don`t know the exact name of the function in the clip menu look up the manual. If you use this function a new window appears where then can make a baselight grading. And here comes the tricky part. You have to know how the picture was shot. Using RED you can do a lot in the setup of the camera like the ISO settings. Also you have to choose the Colour space and Gamma that was used during shooting. These parameters also depend on the firmware of the camera. You see it`s very difficult to do it right. Best way is to get the DOP to tell you what settings he used and what look he intended for his pictures. The Meta Data that comes with the RED files is in most cases neither complete nor correct. And to make it even harder you have to do the pregrade on your desktop monitor which ist never sufficient for doing the job. You often have to try a setting then apply it and check it on your HD video monitor.
If you intend to do the grading in a grading suite you have to export an EDL after you finished editing and deliver it with the original RED files to the post facility. They can then relink to the original RED files and do the whole grading on a machine intended for that.Hope I could shed some light on the workflow.
Yours sincerely Hans

Hey thanks for such a great explanation.
Just 1 more question if you dont mind Once i transcode my footage to quater/half do i have to relink before i export it to a viewing format ie HDCAM or H264?

Hi Ben,
glad I could shed some light on this subject. Once you transcoded your RED files to .mxf you don`t have to relink them when you try to export your cut to a H264 or lay it off to tape. The only reason to relink RED files would be to open the .raw files in a colour grading system like scratch. But this would be done by the grader. You would only have to export an EDL file for him, so that he could relink to the original files. If I understood you right, then you don`t have to do that.
If you intend to work on a more regular basis with RED files I would recommend the book by Noah Kadner to you. He basically covers all the workflows concerning RED.If you have any questions unanswered let me know. I´ll try to help.
Hans
