Can optimized media be ProRes LT?

Jason,

I’m still exploring the program. I discovered this when exporting a video. Previous versions allowed you to export your Project Timeline as a Quicktime.mov and that’s it. I believe optimizing media is done on Import and I haven’t checked that out yet. I”m about to download the new User Guide:

This is a major upgrade that has restored many items not included with earlier releases.

Gerry is correct – below is a snapshot of the Master File/Video codec options. Optimized for me still shows up as ProRes 422. Proxy is Proxy. I don’t see any way to change Optimized to LT …

When you create a project you can choose ProRes LT as the render format.

“Can optimized media be ProRes LT?”

This is an interesting question and one I’ve been asking myself. We noticed that when AVCHD was imported into FCPX 10.0.5 the bitrate was 120 Mbit/s. This is lower than standard ProRes422 (147 Mbit/s, HD at 60i), but higher than ProRes422 LT (100 Mbit/s, HD at 60i).

The footage was HD, but not 60i, so that might be a factor. But we were wondering whether FCPX intelligently scales the quality of ProRes according to the quality of the original media. I believe the bitrate for the camera format was 24 Mbit/s, so ProRes LT would certainly be good enough.

Hurrah…this means they are definitely listening so whoever you are from Apple looking at this thank you.

And it’s moved from SHARE to FILE – SHARE.

I had not noticed because so preoccupied with all the other stuff.

But…are we reverting to FCP8???

Okay Magnetic timeline is probably better than tttt (select all forwards) but they are listening to us.

That reassures me because it means they actually do care which in turn means hopefully they are committed.

Much much better.

So if you choose LT as render format to perhaps get FCPX to work a little smoother will Export override that if you choose lets say Prores 422 HQ when exporting ? Or do I have to delete all render files before export?

ProRes is a variable bitrate codec. If there is any redundancy within the frame it will drop the data rate. Of course any black breaks in the footage will drop the data rate to almost nothing.
