Sharing my first 4K homevideo from my GH4
 

Hi all.

I wanted to share my first 4K (UHD 3840x2160) homevideo. After all, its edited in Vegas Pro =)
Vegas Pro had no problems at all working with the clips from the Panasonic GH4. I have both used 2160p, 29.97fps and 1080p, 96fps. Sometimes I did use proxy files created by Vegas Pro, especially when I first worked with a video file in After Effects, rendered it out to an huge 3840x2160 uncompressed .avi (a 15seconds long clip is about 11gb) and then imported it to Sony Vegas timeline. Those files was better to make proxy's of. For other clips, I only created proxy files for a couple, mostly on clips I used alot of FX's and grading on...

For those who not know my hardware, and wants to know, here it is:
i7 3770k 4.5GHz
32GB 1600mhz RAM
780ti 3gb ram
256GB OS
120GB Scratch disk
640GB Render disk
2TB Media disk
2TB Backup disk

Im not a very active writer on this forum, but I do read this forum weekly, since about 2007. I noticed that many on this forum, editing as their profession. So there are many skilled editors and gurus here.

Me myself only have this as a hobby. Because I love computer/camera technology and my kids.
When I started with editing, I only used stills, because I hated how low the resolution was before 1080p came along. But now when you have 4K, every frame of your movie, is a still picture. My goal is to make homevideos to a cinematic level, something more then just having 50 homevideo tapes laying around in the bookshelf.

Because there is so many great guys here, I would love to hear what you have to say about my first 4K film. That would mean alot to me....

Cute boy and beautiful family.

You have great soundtrack, great audio, wonderful video. Everything looks and sounds very very nice.

It looks and sounds like a movie. Did not get the story, but who cares, it was enjoyable to watch.

Re: Sharing my first 4K homevideo from my GH4
 

Hi Jeff!

Thank you very much, I really appreciate it!

I really wanted the viewer to experience the film like a film, and not a regular homevideo, and wanting to look throw the whole film without scrubbing fast forward or fall asleep... =)

The story was kind of loose.. I actually did the story with the clips I already had, and not vice versa...
Only two time did I go out and shoot because I needed some material for the story...
And my texting wasnt 100% either...

But I am very glad a professional film editor and filmmaker enjoyed my film =)
I couldnt be happier!

Re: Sharing my first 4K homevideo from my GH4
 

As Jeff said, It looks like footage from a feature film.
I loved it.
We should have a thread for "Clips featuring our loved ones". Since we probably have all done them at one time or another.
I learnt most of what I know from doing these.
Not as classy as yours Kim, only 720p GoPro, but a bit of fun-

Re: Sharing my first 4K homevideo from my GH4
 

Thank You, Kim, for sharing Your very nice work.
Greeting from my grandson about the same age who have not yet had time to get into 4k movie ;)
It seems to me to look after the movie clip is not necessary to use all the currently popular techniques. Better impression would be used for simpler techniques.
Here a very simple home video UHD clip from neighbors across the Baltic Sea - from Riga. We currently undergoing light festival Staro Rīga 2014. Clip edited on my internet PC (i5, 8 GB RAM, Intel HD Video) with Sony Movie Studio Platinium v13.0

Re: Sharing my first 4K homevideo from my GH4
 

Thnx Gerald, for your comment. Glad you liked it.
I really liked the animations in your video! Great idea of a thread for this kind of video, maybe you should start one...

Nice to see faces of the guys you often only have text as communication...

Re: Sharing my first 4K homevideo from my GH4
 

Juris, nice one!
Really cool we are sitting in front of our computers talking to each other when we are all scattered around the whole world.
Jeff from US, Gerald from Australia, Juris from Latvija, me from Sweden and so on..

Re: Sharing my first 4K homevideo from my GH4
 

Hoping someone could help me or at least explain to my why this phenomen occur...

In time 4:26 and 5:58 into the film, the clips which plays, is twixtored in slowmotion. When I look at my original rendered film, it plays fluidly and perfect. But I noticed now that my film on Youtube played thoses clips like it was 7fps... Really choppy and bad...

Youtube must have done some strange compression to the film... Is this something I can solve and rerender it differently or something?
Did I do something wrong with my render settings?

Thnx.

Re: Sharing my first 4K homevideo from my GH4
 

Changes between frames is small enough , so YT coder is trying to save bitrate.
Ways to reduce the impact on the quality of coding:
1. Use images with sharper edges,
2. Do not use such a large slowdown,
3. Upload to YT a better quality video with a higher bitrate.

Re: Sharing my first 4K homevideo from my GH4
 

To your answers 1 and 2, then why are the clip at 5:45 playing fine?
That clip is also slowed down, just as much, and has equal sharpness/blurriness as the other two clip....

Other people over the Youtube have thousands of videos with twixtor, retiming videos (slower) way more than I do.

Youtube have done some weird when recompressing two of the clips in my film...

Should it really help rerendering another video with higher bitrate?

My current render setting is:
3840x2160p
profile - main
29.97
mainConcept .mp4
constant bitrate 50mbps
video rendering quality - best

Do you think it would be better if I raise bitrate to 135mbps ?

/Thnx

Re: Sharing my first 4K homevideo from my GH4
 

no idea if this anything to do with your problem....

YouTube Takes the Plunge to 4K ? But There's a Catch

as an aside, and not in the least meant as trolling:

why 4k to youtube? i don't think many viewers will have 4k tv's, and even if they do they'll need pretty good net connect.

in peace ;-)

Re: Sharing my first 4K homevideo from my GH4
 

Well, you do have a choice, you can always watch the film in 1440p, 1080p, 720p, 480p, 360p and 240p...
And the problem is still there...

I bought a 4K TV (3840x2160p) me myself, because when I compare 1080p with 2160p, its really a new beutiful picture I am looking at...
Even with my 1440p monitor which is "only" double the amount pixels comparing to 1080p, its astonishing...
Thats obvious because im sitting about 1-2 feet (40cm) away from the monitor.
And sooner or later, 1080p will dissapear like 480p and 576p did. To have every recordings you have in a more accurate and better picture quality is never wrong.

But of course, why buy/upgrade something if you dont even cant see any diffrences. It up to the individual..

Here in sweden its quite common to have around 100 mbit/sec - 500 mbit/s.
A broadband internet plan at 350/10 mbit/s, is around 350sek (£30, $47, €37) / month. 100/100 bmit/sec is around 300sek (£25, $40, €32).
Its getting cheaper and cheaper to have a good internet connection these days because people doesnt only stream youtube, they stream netflix and other TV services, backup photos and etc. to the clouds, and so on. And family members do share the connection with each other.

/thnx for any help/info

Re: Sharing my first 4K homevideo from my GH4
 

well, with those speeds i might just move to sweden ;-)

thanks

Re: Sharing my first 4K homevideo from my GH4
 

Your welcome! =D

And I wouldnt mind living in Australia for a couple of month christmas time. I get so frozen those icy, snowing and cold month here in Sweden... =)

Re: Sharing my first 4K homevideo from my GH4
 

you wouldn't want to be here now - 40 for the last three days - phew!!!!

Re: Sharing my first 4K homevideo from my GH4
 

I was in Texas, Houston, 3 years ago. It was 42 degrees all week... Loved it! Loved the humid warmness of godness =)
We are hoping to travel to Australia in around 2 years from now. We are a big family (five of us), so its pretty expensive...
But we'll see...

Re: Sharing my first 4K homevideo from my GH4
 

best april may / sept oct - spring / fall. otherwise you might regret it ;-)

of course, we're a pretty big island, so really depends where you're going.

Re: Sharing my first 4K homevideo from my GH4
 

OMG, 42°... 24° may be too warm to me. Kim, You need to go to India!

Re: Sharing my first 4K homevideo from my GH4
 

Just had to say "no thanks" to an offer from a relative "down-under" to house sit for seven weeks while he and his goes walkabout (in his 4x4).

I've a pair of GH4s and lenses, love wildlife videography, never been to Oz and Adrian lives in Cairns.

Too much to sort out in too little time is my excuse.

Re: Sharing my first 4K homevideo from my GH4
 

I have still not a clue why my video on youtube was uploaded and transcoded in this bad way...

And it have nothing to to with 4k to do, because its the same on 1080p, 720p and lower also..

Im hoping someone knows how to get around this. Maybe I should render the video in some different way?

/Kim

Re: Sharing my first 4K homevideo from my GH4
 

Theoretically, YT might not be correctly interpreting your render.

Are you using a Vegas render template? Modified anything?

The settings you posted seem to include an adequate bitrate. You could try Variable Bitrate (VBR) instead of CBR.

Then I'd try a different mp4 codec than MainConcept.

Then i'd try rerendering in Handbrake. Its x264 codec is the best!

These are ideas, and may not be solutions. But if you go all the way to the end you'll have done about all you can.

Re: Sharing my first 4K homevideo from my GH4
 

Yes I am using a render templates "Mainconcept AVC/AAC .mp4".

The only thing I changed was setting the resolution to 3840x2160, changed the bitrate to constant 50mbits and changed the video render quality from good to best.

I changed from VBR to constant only because I didnt wanted Vegas to decompress further scenes, because sometime Vegas "believes" it should lower the bitrate when reading frames, but ending up in just bad compressed scenes...

But I can change this and try VBR if that will work..

Maybe I should change from Mainconcept...

Handbrake isnt able to render 3840x2160 ? I believe I tried before but it wasnt possible to render in 4K or UHD... 1080p is maximum resolution i think.

I'll try changing things in my render template..

Re: Sharing my first 4K homevideo from my GH4
 

Why don't you try XAVC S long-GOP? It was designed by Sony for 4K, and it is the best H264.codec in the package. It will render at 100 Mbps, vbr. Youtube has no problems dealing with it (it is the 4K codec I use to render).

Re: Sharing my first 4K homevideo from my GH4
 

thnx for your suggestion, I will test that out.
I'll tell you if that will do it when I am done.

Re: Sharing my first 4K homevideo from my GH4
 

I did try the XAVC S long-GOP and others, same problem with everone ;)
Strangly, i did render out just those couple of seconds where I did experience the problem. No problem at all. The clips plays buttersmooth in evey codec I test.

It have has to do something when you upload longer videos to youtube. Youtube to some kind of different recoding algorithm to save space on its servers or something... And therefor using same frames when it "thinks" the previous or next frame is identical or very little different.

Anyway, I did in another attempt, upload another cinematic homevideo but this time its all in 96fps with my GH4.
Just wanna share to you guys..

Re: Sharing my first 4K homevideo from my GH4
 

Matching the emotion of a film with appropriate music is an art form in itself. You seem to have the touch.

Re: Sharing my first 4K homevideo from my GH4
 

Oh, thank you =)

I just like to combine great sound scores and build up a memorable homevideo with my kids..
I wish I also had the talent to compose such music. That would be so complete =D

Re: Sharing my first 4K homevideo from my GH4
 

Did you also mix the soundtrack? The voices sound like they were dynamically treated by a pro. Just the right amount of compression, appropriate EQ, there was some reverb on the early voices and a section where they scatter from left to right while always sitting correctly in the mix. It sounds like it was mixed on an SSL board or something at that level. In any event the audio is superb (as is the video) and a reminder of how important a well done soundtrack is. Super job.

Re: Sharing my first 4K homevideo from my GH4
 

I bought the license to the soundtrack (Ember - Tony Andersson) from The Music Bed. So I only placed the soundtrack on top of my video tracks. I havent manipulated or done anything specific to the soundtrack.
Thats if you where wondering if I had "mix the soundtrack"?

The voice is from my daughter Amelie, which is 12 years old. I recorded her in her room with my little recorder Zoom H1 =D. I gave her a "script"...
To the voice clips of my daughter, I have added some FX (Track compressor, Reverb, ExpressFX Graphic EQ and Wave Hammer).
I really know nothing about audio, I just read on the web, trying to found out how to create some "echoing" e.g. that would be why I used "reverb". And the other FX's, I have used to "lift", "enhance" or "change" the voice to what I believe sounds good. But my knowledge when it comes to audio is absolutly zero. Im just trying to "listen" how I want it to be.
My first video which where in 4K, was also expremental...
It's maybe because there is a backgorund soundtrack you really can't hear the flaws =)...

Also the thunder in the beginning, did I capture oncamera last year when it was bad weather.

I'm really glad you liked it! Thanks!

Re: Sharing my first 4K homevideo from my GH4
 

Congrats on the good job, and I'm shearing your desire to use my own moody soundtracks when time comes for short films like yours (as I mentioned in another thread).

Cheers

Here is a color correction & color grading breakdown of my film.
I mostly used Sony Vegas built in CC tools, but also some third party plug-in's...

So watch if youre interrested.
