I finally got around to posting a direct comparison of the AVCHD Codec vs the new Sony XAVCS codec. I used the new Sony CX900 camcorder for this test. This new codec shows up on the AX100 as well as the Rx100 Mark 3. You can see the side by side comparison here.

I did this comparison because I cannot find any online resource comparing the two directly. So I did it myself.
I noticed quite a bit more detail in the XAVCS Shots as well as better highlight handling (less blown areas). Of course you can work around the blown highlights by not shooting in Auto, but sometimes you just want to grab your camera and shoot a quick kid video or whatever. I would recommend using the new codec to do so. In this video comparison I have taken the original video files and re-rendered them as a 28mbps mp4 file. I save all my home movies in this format and wanted to see if the extra detail that is captured using the XAVCs codec would show up in the re-rendered files. It does. You may not notice as much detail in the youtube file...but take my word for it. XAVCs files are more detailed and control highlights better. AVCHD is a codec of the past. Unless space is an issue when on vacation (you will get twice as much recording at 28mbps than with the 50 mpbps of XAVCs) I would recommend using the new codec whenever possible.

I know very little about video, but sounds/looks like some useful info. Thanks for sharing.
