Chroma test on HMC40's 24P and 30P at DVinfo.net

This comparison of the HMC40 with my Canon HF10 (which is known to exhibit interlaced-chroma in its progressive modes) may be of interest.

The first group of images shows pixel for pixel crops, the second group are 3X enlarged in photoshop (for clarity).

I need to qualify my earlier post ... the chroma interlace evident in the Canon clip is NOT inherent to the camera (as I had believed) but a product of faulty H264 decoding. As was demonstrated to me on another forum, HF10 footage decoded with avisynth/libavcodec exhibits no such interlace artifacts.

The main point of my post remains however: HMC40 24P and 30P chroma looks good!

(By the way, clicking on the above images will enbiggen them...)
