Hi!

1. I have dv letterbox material which I´d like to upscale to hd, is there any aspect ratio conversion option like center cut, on the MXO2 for upscaling letterboxed sd?

2. If someone else has digitized for example dvcpro material on his mac with Final Cut Pro´s capture settings, is it still possible to preview/output it throuhg the MXO2 on another mac?

3. Does MXO2 support all Final cut pro´s capture settings and outputs them in true resolution and color depth?

Thank You!!

When upscaling footage from SD to HD with the MXO2, the upscaled footage will have pillar bars. Only when downscaling from HD to SD will you have the choice of viewing your footage anamorphic, center cut or letterbox.

Yes, DVCPro material captured into Final Cut Pro can be viewed on another Intel Mac (that has the appropriate connection for the MXO2) through the MXO2 from Final Cut Pro.

The MXO2 can capture to a variety of codecs, including ProRes 422 HQ, uncompressed HD/SD (8-10 bit), etc…
HDMI monitor calibration
Matrox MXO2 lets you adjust and control your HDMI monitor exactly like you would a broadcast HD/SD monitor. Controls for hue, chroma, contrast, brightness, and blue-only are provided. This unique control gives you completely accurate color representation so that you can use your HDMI monitor even for color grading.

Hi Guys
Is there any intention of addressing this issue in future firmware upgrades?
Cheers

Hello Andy Mees

To not affect the quality of the video being upscaled from SD to HD, the MXO2 will pillar box the upscaled footage.
Matrox doesn't consider this an issue since video quality is a priority therefore this will not be modified in future MXO2 driver releases.

okey dokey, well thanks for the fast and honest, if disappointing reply

can you just elaborate for a moment tho' just to double confirm I'm not misunderstanding you or the function I'm speaking of ... if I send anamorphic sd footage into the MXO2 unit, then will I only be able to get a pillarboxed upscale of that footage? not full 16:9 ... so I have to scale/distort the result manually in software?

whilst I certainly do appreciate that retaining quality is a prime factor, just as a point of reference here would be my "issue" argument (other than the above):
given that no network (or none that I know of) puts pillarbox upscales on air, it may be considered a drawback of the current MXO2 design that one must complete the upscale in software (or use alternate hardware)... noting that Matrox itself only considers their upscale quality to be good to pillarbox level then one could always offer "Pillarbox (Recommended)" in the options and allow users to take it from there, but I do see a strong argument for Off, Center Cut and Squeeze in the upscale options list.

ho hum, maybe in the MXO2.5 Smile

best
Andy

Hello Andy

Specifically when upscaling 4:3 material to 16:9 through the MXO2, the output is pillarbox.

Anamorphic SD…that's a different story.
Matrox product specialists tested upscaling anamorphic SD footage to HD through the MXO2 and it displayed the full 16:9 aspect ratio, no pillarbox.

Have a good weekend,
