[video] Making Production Technique Videos (Complete Tutorial)

[kingozrecords]

Though a buggy product, for free products; I'd say that openshot creates better video than blender.

Still processing, yay!

Yes, I have slow internet and the video takes a while to get processed, sorry.

It sounds like I was complaining, but I wasn't. Covid has forced me to do a bunch of video production that I never would have done otherwise and so, this past year, I've learned all about youtube taking its sweet-ass time to process video. It was meant to be a bit of snark directed at youtube, not a criticism of your efforts, which are appreciated!

Yes, I understood .

I've recently gotten a handle on everything and I can even make one video about fixing the grainiest video imaginable with a decent res. It's actually possible to make it look pro. It's a bit of a trick but I'm sure someone might benefit from it.

This had been a post regarding converting 30fps to 60, i found the results varied and incosistent. I'll find a better product and post that within promptly.

I promised a video de-noising technique. This is something that not only succeeds but potentially can do everything in one step. Now I need to write the calls to process and denoise, amplify and equalize the audio also; so that this can be done on the fly.

Here's the ffmpeg code.
https://www.youtube.com/watch?v=4YlE_numGxs

Code: Select all

@echo off
cd /d %~dp0

set ffmpeg="ffmpeg.exe"

%ffmpeg% -i in.mkv -crf 7 -r 30 -vf nlmeans="1.0:3:3:3:3",hqdn3d="1.0:1.0:11.0:11.0",removegrain=5,removegrain=5,"eq=contrast=1:brightness=-0.05:saturation=0.95" -vb 12.5M -b:a 192K -map 0 -movflags +faststart out-onepass.mkv

It was a challenging scene to denoise because I wanted the background dark. I like to use this motif at times because it looks natural and comfortable. It took three passes and roughly 2 hours. I'm hoping this new method can cut that time in half, but it's not designed to process audio yet.

Updated to match the quality of NLMeansCL

I decided to change the spatial temporal filter so that it only uses temporal filtering. The results are much better than merely nlmeanscl and hqdn3d.

If you've been following you will notice that I am now very close to having sharp lines that are subsequently denoised also. These are areas which are almost impossible to target but the removegrain filter at its gentlest setting does seem to be a good result.

Here's the list of de-noise filters that are fruitless to try:

• BM3d Blurred guassian, fruitless, better for anime
• NLMeans Not vivid enough, dulls the picture, only QTGMC methods are good, or NLMeans openCL.
• OWDenoise I sure get tired of people pretending to try things online. If they had have tried, they'd see that this method runs at 0.1 fps on a pretty goof cpu.
• VagueDenoiser I've seen good results with this method and bad results. If you know about this denoiser, and understand it; maybe share the info please?
• DCTDNoiz was probably the best of the obscure denoise methods I'd tried. But it's slow. Maybe by using an Nvidia or AMD specific hwaccel routine and codec like nvenc and vaapi you could employ

  Code: Select all

  -vf dctdnoiz=4.5

  It might be a nice "last word" if you're desperate

Recording Graphically Intensive Apps with Webcam Footage

Here is a guide for those needing to get graphically intensive applications on video while they have webcam footage simultaneously. It works and it surrounds using obs and sharex together.

https://youtu.be/kfKlPk_wI4Q

It works well and I was able to get a demanding game on video while commenting and recording webcam footage (using a mid level system). Took Me a weekend to learn. Always a new mountain to hike up.

To KingOzRecords, i kind of glossed over your entire thread. It looks like maybe you're way over complicating things for yourself and maybe others.

Not really, it's all pretty simple in comparison to dsp. Actually, it's kind of a nice less complicated respite. Easier than making a brickwall limiter.

However if financial limitations are the reason why you can't get a better camera, and you don't mind waiting then there are ways to increase sharpness. The best software I've used to upsample stuff is called Topaz VideoEnhanceAI https://www.topazlabs.com/video-enhance-ai

Especially given that it's covid times still, yes. But most musicians don't make much. Yes I geared every tut towards free stuff and cameras that cost 100 dollars or under. My entire computer cost 780 dollars canadian. It has 4.25 gz without overclocking ddr3 ram @13333 and a gtx 960 w 4gb ram. Also including a 7200 rpm 256mb cache 3tb hdd with two ssd's. One Samsung 1tb 980 (os) and a 500gb 970 (games).

There are cheaper builds even still, but I wanted something very reliable.

You make good points, I think most of all I wanted to point out that many suggestions regarding fps, ffmpeg and whatnot are not realistic. I pointed out there's only often like one or two options in the end. As a developer I remember trying every combo. I was hoping I could save some people time. You remind Me though, I should take a look back at it all again and clean it up so that it's more straightforward.

I replaced the initial video with something more modern which goes over the fastest build with obs possible.
Read the first post

As a film maker I usually say "Crap in, crap out" when it comes to video quality meaning if your camera is not the greatest you can't really fix it after the fact. Well you can try but the amount of time required is often just not worth it.

This is meaningful and the video you posted is regarding a very respectable camera. But there still stands in the way obstacles. You need a special device that turns that in signal to plain video first. So, if you had a great camera, even then - Your cpu would be bogged down.

If you got the buffer you needed, then there would be next to no impact on your computer but with the camera and the device about 800 dollars. Blackmagic makes them as do other companies. The best way to shop around for them is to watch youtube examples that have actual video footage. If they specify a specific camera then I would suggest you stick to those parameters to avoid expensive surprises.

btw, I'm making a custom screen recorder program now because I have been frustrated. I'll try to add automatic camera footage cleanup and there will be two tracks to enable post processing. The results are good so far.

[kingozrecords]

I decided to try to use the old fl studio 10 (non-extended memory edition) that uses next to no cpu to process vocals for obs. The results were noiseless, free of pops, and glitches that I've become accustomed to when using obs studio.

I use three free 32-bit plug-ins to achieve the de-noising:
Werman RNnoise denoise: https://github.com/werman/noise-suppres ... e/releases
Rescuemk2: https://plugins4free.com/plugin/663/
CompressiveCM: https://plugins4free.com/plugin/1537/

Versus 79.99 usd for this product:
https://www.topazlabs.com/denoise-ai

And unlike topaz, once you gain the knowledge you can also change the temporal and spatial effect. Knowledge is much more effective than ai. But topaz is good.
Where I would consider the topaz effects the most is in sharpening and making video look more vivid, because the denoiser has so few controls (that are much needed).

To KingOzRecords, i kind of glossed over your entire thread. It looks like maybe you're way over complicating things for yourself and maybe others.

And I realize that knowledge regarding the time and frequency domain being in regards to minute time based adjustments (temporal) and finite, subtractive changes (spatial) edits seemed fussy and annoying, but they are the tools of a surgeon, not of a nurse.

It uses about 12% max cpu. I explain how to make obs that efficient in this video. Because even if you have a really sick computer, you only want to run more demanding gear and apps, it's better to use that power towards that versus obs.

https://youtu.be/Jr2V8enWw5o

I de-noised the video with the free video enhancer2 by infognition. The results are comparable to topaz studio, and it takes about the same amount of time. For less problems with patterns on drab grays, set the the temporary cleaner down slightly.

How to Download OBS for the Mac M1

For those using m1 arm64 mac monterey using a logitech c920 webcam or similar, apparently this software allows you to change the settings:
https://www.logitech.com/en-ca/video-co ... tware.html

For an obs installation that works with your arm64 chip, it's a bit involved. I revised this new instruction list to better help you.
I was able to ascertain how to download here.

In that, it says:

Hi, is there a tutorial on how to use this PR to build/download binaries for apple silicon powered Mac? Thx!

Download the latest builds from the master branch by checking for the latest build from the obs-studio repository's main page.

where to get arm64.jpg

• Click the green check mark.
• Click "Details" on any entry listed in the menu that appears.
• Click "Summary" on the page that loads.
• Scroll to the bottom of the page and download the macos-arm64 build, currently labeled "obs-macos-arm64".

Now, that all works, but to download the .zip file; you will next have to register with github. Register and once logged in, you can download the artifact, that is essentially an install build (you will get a .dmg file inside the .zip).

I doubt I could improve on this, unless there's a new obs build that introduces some new code that's m1 specific; designed to accelerate processing

using openshot in an m1 mac mini
a few quirks in openshot, but I show you how to cicumvent them.
https://youtu.be/p1GaRaK7RQg

openshot is much more stable in mac than it is in windows.
Here's ideal audio settings (will be updated when perfect)

loading video settings in the logitech c920 in mac m1
https://youtu.be/2d6QXg8bnRc

An imperfect science, but the only form of control for your logitech c920/c920 s pro. To gain finer control of exposure; turn on and then off auto exposure and then adjust. Temporarily it offers much finer control. But, you will need to re-ajust the next time :/
