I've been a moderator here since February 2014. I've done audio/visual production work as a mix of hobbyist and professional levels for the past 17 years. While my career is a software architect, I studied Electronic Media, Arts and Communications in college as a dual major (with Computer Science). I have worked professionally as a producer (doing both the audio and video) for distance education classes while in college. In addition, I produced the 3D animated intro video for all the distance education classes. I also worked with the paid Audio and Lighting organizations in college.

I have run the DVD Production efforts for Wiicafe covering the Electronic Entertainment Expo from 2002 to 2006 and also ran a wedding videography business for several years. I have since moved on to a wedding photography business after my second camera man moved away. Finally, I also production work for several annual conferences and have worked with multiple music festivals over the years.

I got my start working with crappy gear for non-profits and worked my way up through better levels of gear and training as I moved in to a professional level of work and then further improved through my college studies. I have also been the sound and at times video guy for the various churches I've been in over the years.

comment Does oval-shaped bokeh indicates that the aspect ratio of the image was modified?
Ok, this was my first thought and from doing more research, I agree it is correct, but I still don't understand how it works optically. If the image is a circle getting compressed on to the film, it should be a circle when uncompressed, if it was a circle after compression, it should end up elongated in the horizontal. What am I missing that makes it so it elongates vertically, even after uncompressing the image. Is it just that something about the optics compresses the bokeh more than the in-focus image?

comment Is it right time to buy 4K video camera?
+1, solid argument that the best camera is the one you have with you and 4k on a mobile does give you more to work with than 1080p, even if you just end up downscaling it to get around the high levels of shoddy, real time compression most phones throw on 1080p.

If you can add some details relevant to the question or explain why you think your take on the question is correct (I tried but couldn't see it) and fix the misleading points, then I'd be happy to change it from a down to an up.

Similarly, many of the compression artifact in the lower version of the video are likely related to over-recompression. When compressing from a low quality source to another low quality source, it is more likely that artifact not visible to the eye in the first video will become apparent. If a high quality source 4k feed was used, then the quality of the encoding would be much better, even at the same file size since the encoding would be working on source and not artifacts as a starting point. This is why, as you observed, the problems are most noticeable on the Xperia.

Note that there are also some minor technical inaccuracies or points that are misleading. For example, while the file size is around 1/3 for the Youtube clip, that doesn't mean that there is necessarily 1/3 of the meaningful information. Rather, a small amount of low value information is discarded resulting in allowing far better compression of the remaining data, so less than 2/3 of the information is actually discarded, it is just made to be more compact and even the data that is discarded is selected for lack of importance.

comment 4k vs. 1080p on a 1080p monitor
Hey, welcome to Video Production, sorry to down vote, but this really doesn't seem to actually provide any information relevant to answering the question. You provide good coverage of if a 4k source is comparable to a 1080 source and you provide an ok description of the difference in youtube 4k re-encoding vs the original footage, but nothing in your post really touches on if it is better to watch 4k footage on a 1080p monitor or the scaled down 1080p version of the same footage, which is what the question seems to be asking about.

comment Recovering severely underexposed video
+1 That's fair, I don't mean to detract from your answer, just want to make sure they understand that if there is enough there to extract, they don't have to buy a $600, $240 a year program or $30 a month program to do it. It's also probably worth pointing out that if they want to go super advanced, either Speedgrade, After Effects or Divinci Resolve would all offer even more advanced options (though I understand that you were explaining what you know.)

Can you post a sample frame of the video? This will help us let you know if it is salvageable or not and possibly suggest some settings to try if there is enough detail there to expand.

comment Recovering severely underexposed video
Premiere is overkill for this. Any tool has basic color correction necessary for expanding the luminence space of the video, however if there is as little detail as he is claiming, it is unlikely to make any difference in the first place as there is nothing at all to expand.

Do also note that this question may already cover some of your concerns. Be sure to take a look around the site at existing 4k questions to see if they cover your concerns before asking a new one.

comment Using LG G3 for youtube videos
As this is currently stated, it is impossible to give a correct answer. We'd need far more information on what you are trying to do, what your reasons for wanting to upgrade are, an understanding of how valuable those reasons are to you, etc, etc, to be able to answer this "correctly". It's either worth it to you or it isn't, someone else really can't tell you what it is worth to you. You could try instead asking something more like "what are the advantages and disadvantages of producing 4k content for Youtube?" if you are trying to better understand the value of the format.

comment How to handle Rode VideoMic Pro during transport?
Vanguard also makes a nice cheaper version styled after Pelican. They aren't as insanely durable or water-resistant, but they are also like 1/3 the price.
