Apple Color Testing Part 3 - 720p/60 DVCPro HD

COW Blogs : walter biscardi's Blog : Apple Color Testing Part 3 - 720p/60 DVCPro HD

My tests on DVCPro HD 720p/60 MaterialTest One:I opened Color and brought in a 720p/60 DVCPro HD clip to a timeline.1 - The clip shows as 1280x720 DVCPro HD and not 960x720 like it should.2 - I cannot select DVCPro HD for the codec anywhere.3 - I cannot set the Frame Rate to 59.94. It is greyed out in 23.98.

UPDATE - This was operator error, frame rate needs to be set before adding a clip.4 - I could not render out a DVCPro HD File, the option to render out in “Original Format” is greyed out.Now for this test I simply brought in a single clip, I did NOT export a timeline from Final Cut Pro. BUT I should be able to work with a single clip or clips correctly in Color without having to come in from an FCP timeline. So again, for this test, poor performance from Color.Test Two:Send To Color a 14 second timeline from FCP. 720p/60 DVCPro HD timeline.Frame Rate in Color – 59.94Frame Size – 1280x720, this is wrong. Should be 960x720 but there's no way to change this.Render out the project and Send To Final Cut Pro.Sequence Settings – DVCPro HD 720/60. This is correct.Frame Rate – 59.94Frame Size for the clips – 960x720. This is correct.Image Quality - I'm seeing bad rasterization on any vertical or horizontal lines and an overall degradation in quality from Color. Video has taken a bad image quality hit with a lot of compression artifacts visible during playback and especially when in pause. Test Three:Same as above, but this time Render out Export to ProRes 422 (HQ)The Sequence that opens up in FCP is a 720p/60 DVCPro HD Sequence. This is strange because I chose ProRex 422 (HQ) as the export / Render option. Compressor is still DVCPro HD in the compression settingsFrame Size for the clips – 960x720. This is correct for 720p/60 DVCPro HD.Image quality – Identical to the DVCPro HD render, which is quite surprising because in the 1080i/50 test, the Pro Res render was very sharp.I'm seeing bad rasterization on any vertical or horizontal lines and an overall degradation in quality from Color. Video has taken a bad image quality hit with a lot of compression artifacts visible during playback and especially when in pause. Conclusion:Rendering both in DVCPro HD and ProRes 422(HQ) yielded the same bad, unusable results in image quality. The results of my 720p/60 tests are nearly identical to the issues I was seeing in Final Touch HD 2.6.

Apple Color 720p/60 DVCPro HD with Color 1.01
by walter biscardi

Revised Tests using the new 1.01 Update

Test One:
I opened Color and brought in a 720p/60 DVCPro HD clip to a timeline.

1 - The clip shows as 1280x720 DVCPro HD and not 960x720 like it should.

2 - I could not render out a DVCPro HD File, the option to render out in “Original Format” is greyed out.

3 - Render out to ProRes HQ

4 - Send To Final Cut Pro. Final Cut Pro properly creates a ProRes HQ timeline and the clip looks perfect. This does work, but not exactly what I would like to see.

Now for this test I simply brought in a single clip, I did NOT export a timeline from Final Cut Pro. BUT I should be able to work with a single clip or clips correctly in Color (i.e. DVCPro HD) without having to come in from an FCP timeline. The render to ProRes HQ was fine, but I would really like to see the option to render to "Original Format" unlocked or the DVCPro HD codec added to the render choices for projects that originate in Color.

 

Test Two:
Send To Color a 14 second timeline from FCP. 720p/60 DVCPro HD timeline.

Frame Rate in Color – 59.94

Frame Size – 1280x720, this is wrong. Should be 960x720 but there's no way to change this.

Render out the project and Send To Final Cut Pro.

Sequence Settings – DVCPro HD 720/60. This is correct.

Frame Rate – 59.94

Frame Size for the clips – 960x720. This is correct.

Image Quality - Perfect. This has been corrected.

 

Test Three:
Same as above, but this time Render out Export to ProRes 422 (HQ)

The Sequence that opens up in FCP is a 720p/60 DVCPro HD Sequence. This is strange because I chose ProRex 422 (HQ) as the export / Render option. Compressor is still DVCPro HD in the compression settings

Frame Size for the clips – 1280x720. This is in-correct for 720p/60 DVCPro HD.

Image quality – All images are stretched badly horizontally because they come in full raster 1280 wide instead of 960 wide for a DVCPro HD timeline. Either Color needs to create a ProRes HQ timeline or it has to render in the correct DVCPro HD frame size.

If I go into the Motion tab and Disort the images to 33, they now look correct on the monitors, but all clips have to be rendered. So that's not useful since it would be a double render.

Now if I Copy all the material from the DVCPro HD timeline and Paste than into a 720/59.94 ProRes HQ timeline, all of the clips are fine. I don't see any noticeable difference between the DVCPro HD render and the ProRes HQ render.

So this works, but with a workaround at the end.
