If your primary is shooting video, have you look into the Panasonic LX100? Or are you settle with interchangeable lens system?

However I do not see this in the clips produced. Also reduce noise is nothing to do with scaling, scaling is a linear activity so noise is unchanged


It's call Noise Averaging, some people call Frame Averaging:




Besides, the discussion brought up a good point. If you choose 1080p setting on youtube and play back on 1080p monitor, vs choose 4K setting on youtube and playback on 1080p monitor. Which one looks better?


I'm not interested in the science behind it. I just know that when I watch 4K published setting on 1080p monitor, it looks good.


The GH4 has 200Mbps 1080p recording capability. I'm not sure if someone tested 200Mbps 1080p vs 4K downscale to 1080p or not.


At the end of the day, I think people should just publish to 4K if they're shooting 4K, unless they have a really old computer that can't handle 4K processing. My 4 years old Intel i7 desktop can handle 4K editing with Premiere, so editing shouldn't be an excuse. In many part of Asia (South East Asia) where internet speed is super slow, uploading 4K content to Youtube may be one of the reasons people in that region do no publish in 4K.


Also, may be this help?

People should only scale 4K down to 1080p if:

1.) They want to reduce noise

2.) apply pan & scan technique to recompose image or create a slider effect

3.) Post stabilize image to crop away some 4K pixel and scale to 1080p.

4.) Create a zoomed in effect, like the Clownfish egg result posted in this forum not long ago.


Otherwise, no point to spend the money on 4K equipment just to shoot like 1080p right now.

What lens are you using? Have you tried the 14-42PZ with wet lenses?


To be honest the more I see GH4 clip and more I think that once scaled down to 1080p and put on youtube they look no better than my Sony RX100 MKII and now Panasonic GX7 clips shot at 24 mbps


Yeah I still see a lot of GH4/AX100 shooter output to 1080p only. Yes, 4K TV/monitor is not common in Asia or some part of the world, but output to 4K now will make your video relevant and have longer shelve life 3 years from now. I think 3 years from now not many people would want to watch 1080p content in youtube, just like right now I don't watch 720p or 460p video in youtube, unless it's just product review which doesn't have long shelf life anyway.

I suspect Canon would try to market the XC10 to film students or videographers on a budget. GH4 and A7s require commitment of buying lens, and could be a confusing route for people who starting out videography and don't know much knowledge about dSLR.


I have a friend who's in film school now, and he has no idea about using what lens on what body, let alone speedbooster. All he learn is broadcast equipment that the school has, and of course he can't afford a C300. I think Canon is smartly trying to grow their Cinema EOS line users by offering a prosumer camcorder or dumbly try out the market just like their EOS-M line to see what's the response. There is also these discussion about the XC10 is targeted for journalists who's on the field and do not want to spend time to change lens or carry all the lens, hence the long zoom on the XC10. Many news/journalist are putting content online now so they don't need the kind of quality that could be projected on a 60 foot tall movie theater, so 1" sensor is good enough?


Again, these are just speculated conclusion that people drawn, no one from Canon really want to explain their strategy.
