Why does the video from the A7S3 and FX3 look different?

[vnewbie]

The A7S3 and FX3 are supposed to have the same sensor.  I have seen a few videos that compare the video from the cameras two side by side.  To me the colors look deeper and more vibrant on the a7s3.  While the colors on the fx3 look subdued and dull.  Shouldn't it be the same?

Here are some videos that show this:

I haven't looked at the videos, but if one was shot using S-Cinetone (for example), and not processed correctly, then the colours would indeed look flat and dull - I've seen at least one video that demonstrated how big the difference could be.

That's ignoring all the usual things that could be different - the lighting conditions and all the camera settings.

I wouldn't judge the cameras without knowing that the people shooting them know exactly what they are doing.

The videos show side by side comparisons.  They seem to be done by people who know what they are doing, though none mention what settings are used on the camera.  And they all seem to show the same difference: the colors on the a7s3 seem deeper and more vibrant.

The fact that these cameras share the same sensor says nothing about the resulting colors. The colors that are produced by the camera are mostly determined by post-processing of the raw data in-camera. The default white balance profile may be slightly different between these cameras.
