Aynsley Baldwin, that is all correct information. One thing you have to keep in mind is Avid is not Adobe or FCP and this has nothing at all to do with colorspace like still images colorspace.

This is all about what a consumer TV in your home can handle. What is the colorspace of the device the footage will be viewed on in the end.
We add video “color space” for each time the industry changes. think RGB is a computer monitor, REC709 is your home TV, and now we have 2020 and beyond!

Avid just always assumed back in the day that you were going to output via a broadcast signal. 709 simply has to do with blacks and whites, or Y waveform (luminance) Avid always would output via 16-235 in the Y channel.

We asked you what type of footage you were bringing in so it could deal with the white and blacks levels correctly.

“one thing though… it is a bit confusing that its called RGB 709. unless i’m terribly wrong its a mistake on Avid’s side. it should be called 4:4:4, or just RGB ”

This is not a mistake, it is due to the fact the avid will always output at rec709.

How have you imported this into the avid?

I would also make sure you have the correct codecs package installed on that machine. If you still have the Avid installer Disc or file, just go into the installers folder and install the Avid Codecs PE and LE. Then try again. You might want to try a small chunk first. I would also try to save it local instead of to an external drive.

Hi,

If you are seeing green dots in the middle of clips when they are in a sequence they have motion adapters on them.

This means some clips are a different frame rate! You can find this out by adding the FPS column to the bin through text view.

This is how you can mix and match frame rates. It is done automatically by the editor, and it is based on your projects settings at creation.

Do you have effects on your audio clips? You might have a piece of corrupt audio. I would suggest deleting your Precomputes and re-render.

Hi Robert,

Are you mounting a XDCAM disk or sxs card through AMA?

I think you might want to trash your data base files that live inside your Avid Mediafiles folder…Avid Mediafiles/MXF/1 You want to trash the .mdb and .pmr files

You can also just use the media tool. It is under your tools tab.

Select the drive letter of the mounted disk or card and all projects within the media tool. That should load the XDcam clips into a bin, you can then move those clips to another bin inside the project.

Or you can try linking through AMA, then transcoding the material.

Hi Michal,

What flavor did you transcode your AMA sequence as?

What Version of the software are you using?

What material is linked through AMA? (P2, XDCAM, QT?)

If an error message states that you cannot export a QT ref. listen to the message, it most likely does not like the codec you transcoded to.

I would suggest DNxHD.
