Drop in quality after using Final Cut Color
on Feb 4, 2012 at 2:18:44 am

Hi - I have a project that I have edited in Final Cut 7.0.3
Sequence Settings:
1920x1080 30p
Square pixels
Compressor: XDCAM 1080 30p (35Mbps VBR)

In my sequence in Final Cut Pro, I use the "Send to Color" option to send my sequence to Color.
The project settings in Color are as follows:
Resolution Preset 1920 x 1080
Export Compressor: Uncompressed 10-bit as well as Apple Pro Res 422 (HQ) (I have tried both)

When I "Send to Final Cut", there is a visible drop in the quality as compared to the original XDCAM timeline.

Is there a way around this or do I just have to live with the drop in quality.

Thank you very much for any advice,
Bijoyini

Something isn't right. Color has been used professionally for the last several years by thousands of users all over the world, and I use it. No loss in quality, ever.

How are you monitoring?

What are your render settings?

Render Settings in Color: Apple Pro Res 422 (HQ)
Formal Width: 1920 Height: 1080
FCP Version 6.0.6
Version of Color: 1.0.4 (I was using the Final Cut Suite 2 HD and was mistaken in the versions in my original post).

We also tried Uncompressed 10 bit and 8 bit.

RENDER SETTINGS IN FCP:
Compressor: XDCAM 1080 30p (35MBps VBR)
Video Processing: Render in 8-bit YUV

Late last night we tried a different method. We copied the sequence from the XDCAM timeline to an Apple Pro Res 422 HQ timeline in FINAL CUT PRO. Then we rendered and sent this sequence to COLOR, did some color correction and sent it back to FCP.
This indirect method made a HUGE difference in quality.

But my question is: Why do we have to convert the XDCAM footage in FCP FIRST BEFORE sending it to Color? Should not COLOR handle the codec conversion/compression?

Thanks a lot for your reply!

The image after being color corrected using Color looked less sharp. The difference is very subtle but unacceptable.
We are using an external monitor and when we zoom into the image at 200% to take a look at the fine details, there is a big difference between the pre-color corrected version and the post color version.

Render Settings in Color: Apple Pro Res 422 (HQ)
1920 x 1080
FCP Version 6.0.6
Version of Color: 1.0.4 (I was using the Final Cut Suite 2 HD and was mistaken in the versions in my original post).

Color improved with version 1.5 particularly in the way it handled camera codecs. The important aspect in your render settings is also the bit depth. If the render is set to 8 bit it might explain the drop in quality post grade.

Check and see if your render settings are at least 10 bit. You can also chose 12 bit or floating point but these take longer to render. I usually set for 12 bit and that has quality but reasonable render times.
