GM1 video quality?

GM1 video quality.

 

With the Panasonic GM1 having the same sensor and processor as the GX7 I would assume that they would have identical video image quality at the same settings.  The GM1 doesn’t have 60 fps, which is presumably down to heat.  But at 24 frames a second it should be the same.

 

Video samples from the GX7 that I have seen seem to be pretty much on par with the GH3,  however samples from the GM1 on YouTube seem to be lower in quality.  Less detail and obvious aliasing on diagonal lines.

 

Is this due to the settings used by the testers, or how they have uploaded the video?

Or could it be due to the automatic corrections being done for the GM1kit lens?

Or could Panasonic have artificially lowered the quality for some reason?

 

Here are some examples (obviously view natively at 1080p for maximum possible quality)

The next one looks particularly mushy.  I’m hoping it’s because it hasn’t been focused properly.  Front focused with a high f number maybe?

If you look at the test for the GX7 from the same people it looks remarkably sharper:

I am also interested in the GM1 video.  But we will need to see some original files first before we can come to conclusions.

Any Vimeo samples? I can't take YouTube seriously as an image quality test.

First Vimeo sample was just posted.

Here are a couple from Cameralabs shot at 1080i50.

Another test was posted comparing 1080 24p vs 50i(17Mps and 24Mps)
