NX1 gives consumers a "counterfeit" 4K video - the exisitng (HEVC Main Profile, Level 5.0) video compression outputs only 80bmps 1080p, but for 4K (as advertised) the NX1 needs Main10 Profile, Level 5.1

Submit a Consumer Complaint to the FTC

 

Where did You get that from?

From MediaInfo on NX1 clip: 3840x2160 HEVC (Main @ Level 5.1)!

do the math - for UHD 4K, the NX1 needs at least 120mbps (70mbps x 1.77x crop) to match the NX500

Your math is wrong. The crop factor has nothing to do with the bitrate. Both cams: 3840x2160! NX1 at  80 Mbps, NX500 at 70 Mbps.

I´m not impressed at all. Looks very contrasty with blownout highlights. I dont get the all the praising comments on youtube!

1080p does not look great! Soft and full of moire.

I did check both the video samples for download above with ffdshow internal reporting to .csv file.

And it did report an I frame every 15 frames. 448 P frames and 32 I frames. For the clip with water.

The magic happens when I open the clip in fusion. I expected to see mush with huge blocks at best. But this?
Not sure if fusion is responsible for grain or not but I can't get anywhere near as good of a result by converting it to another format.

When I went through the file frame by frame in avidemux, I counted 29 P-frames in a row, but mediainfo reported a GOP of 15 as you said.

I don´t know if avidemux shows it right.

Where can I go to teach myself about this?

Finished downloading the file and looking at in FCPX, it looks highly detailed, but whenever there's movement of any kind, blocks start appearing around the detail- looks like crud. Let's hope this isn't representative of Fuji "fixing" issues with aliasing. Let's hope this isn't what the final product will be!

Hello,

I`m new to this forum, but a long term reader, because it is the best forum for information about NX1 (which I own).

The Fuji got my interest for its pleasing colours.

I downloaded two original files from http://www.dkamera.de/news/preview-beispielaufnahmen-der-fujifilm-x-t2/

and discovered, that the codec implemantation may not be very good.

It uses a "High L5.1" variation of mp4 at 102 Mbps with no CABAC and no B-frames unlike for example Sony RX100IV etc.

One I-frame followed by 30 P-frames according to mediainfo and avidemux.

Just like smartphones, but at a higher bitrate.
