shooter Posted September 23, 2015 Share Posted September 23, 2015 I find Emanuel's posts in this thread very useful. Wait, this discussion isn't coming from another thread??I also find them useful. We just bought a Shogun for our A7 M2. That test made our purchase. No buyer's remorse. Emanuel 1 Link to comment Share on other sites More sharing options...

Gregormannschaft Posted September 24, 2015 Share Posted September 24, 2015 Really keen to hear of some actual user reactions to using the camera and hopefully see some footage in the next few weeks outside of those generally awful Sony promo vids.

LOL Don't try to take advantage because some other poster said yes in some other topic as the only way to make a point on yours ;-)This test (not mine) is "my contribution" to this thread: That banding doesn't happen because of 4:2:0, it happens because of compression. Compression takes out bits and bits of material. Your 8bits get compressed down to 6-7bits and then expanded back up to 8 in essence. 4:2:0 vs 4:2:2 has nothing to do with banding, only with edge / color sharpness.

paulraymaekers Posted September 24, 2015 Share Posted September 24, 2015 and can anyone confirm that the A7S outputs 1080P 50frames/sec over the HDMI? (in crop mode for sharpness)can any one confirm that A7S outputs 1080P at 50 frames? (crop mode) Link to comment Share on other sites More sharing options...

You miss the point of Emanuel. He didn't say 4:2:0 is the reason for banding. He said you don't need 10 bit to avoid banding. Higher bitrate 4:2:2 is okay. I've done tests with the Shogun. Same results of that test. Emanuel 1 Link to comment Share on other sites More sharing options...

Thanks : )Output A7R M2 is 8 bit 422. Better bit rate, less compression help. That test posted by Emanuel is correct. We will test with a GH4 of a friend of us. I can inform you later.

Super Members Mattias Burling Posted September 24, 2015 Super Members Share Posted September 24, 2015 I can test HD 35mbit 422 vs HD 20mbit 420.Thats the closest I can get in mbps. Unless I go 4k 200mbps from the xc10 vs my smartphone. TheRenaissanceMan 1 Link to comment Share on other sites More sharing options...
hmcindie Posted September 25, 2015 Share Posted September 25, 2015 444 is good for certain work, a waste for other needs. 420, generally, too compressed, a pain in the ass.One thing good about 4:2:0 is that you can immediately spot how it would look like in youtube/tv anywhere. As everything that comes out anywhere (except the cinemas) is basically 4:2:0.That can lead to awesome situations like doing a cool ass very saturated animated commercial in 4:4:4. Client loves it, everything looks great! But when it comes out of the television or goes out to youtube: "OH MY LORD what are those huge blocks of colors next to my red text on green background?!"

Thanks : )Played a bit for first time today. Nothing scientific. To the eye, you don't notice any difference. My friend will grade it. We'll see his findings.

Gregormannschaft Posted October 7, 2015 Share Posted October 7, 2015 Isn't it a tad strange this is shipping next Friday in the States, and there's been no more footage or first impressions...or anything? 1tkman 1 Link to comment Share on other sites More sharing options...
Rinad Amir Posted October 7, 2015 Share Posted October 7, 2015 A7 series owners will also get free update firmware 14bit sometime in october ibelieve kind exiting news as am eager to see how this will perform & DR ofcourse Link to comment Share on other sites More sharing options...
Husah Posted October 8, 2015 Share Posted October 8, 2015 Isn't it a tad strange this is shipping next Friday in the States, and there's been no more footage or first impressions...or anything?because no one has the camera till Friday? Once it's shipping, there will be a hundred reviews Link to comment Share on other sites More sharing options...
Emanuel Posted October 8, 2015 Share Posted October 8, 2015 Isn't it a tad strange this is shipping next Friday in the States, and there's been no more footage or first impressions...or anything?It can be because actually, the Mark II is a mere update to the older sister, based on the goodies brought from a7RII (such as more power processing, in any case, still overheating according to the early reports from manufacturer), except sensor design, including the same sensor, contrast detection AF, etc...

Gregormannschaft Posted October 8, 2015 Share Posted October 8, 2015 because no one has the camera till Friday? Once it's shipping, there will be a hundred reviewsI thought Sony shipped review units, like how Cinema5D got their hands on the A7RII pretty early and posted lots of video impressions. Very curious about it overheating, the colour and how SLOG3 holds up. Link to comment Share on other sites More sharing options...
