Video on Youtube distorted

Hi, and welcome to the user to user forums.

I have looked very closely and repeatedly at your upload and can find no distortion at any point of the video. Not so much as a flicker. If you check the Stats for nerds box on the video and check you are not dropping frames at your end when viewing.

@sven-m8681

Can you post a full screenshot of a frame of your video when it's in VLC Player so we can see the difference between the MP4 file and the YT version? It's hard to spot what's wrong just based on the YT video. It's got all sorts of ugly artifacts but that may just be the game video display itself. It's very hard to spot any "distortion" per se because there are no natural objects to relate to.

In the meantime, given that the original export is good but the YT video is not, you could try these:

-Export your game play at 2560x1440. That will force YT to process it in the VP9 codec, allegedly better than the current AVC. Just a short trial would do.

-Export a short section in another format such as MPEG 2 (15,000kbps) and upload that to YT and see how it turns out.

Good Morning Ray

Thanks for your quick answer! But I don't understand ... how can you not see the problem?
I checked on two mobiles and three different pcs (two of them high-end machines with fibre internet), I see the problem on all devices.

I uploaded screenshots, so you can see what I mean:

https://freeimage.host/i/0058-bad.HowESee
https://freeimage.host/i/0058-good.HowEUmu

First one (0058-bad) is what I see on all devices on Youtube.
Second one (0058-good) is what I see on my video on my local pc (vlc media player).

You can clearly see the difference (especially when you check the times in the middle/bottom.
Hope this helps :)

Thanks for your further help, cheers

Good Morning AAProds

Thank you for your answer.
I posted the screenshots below, I'll send them to you too here:

https://freeimage.host/i/0058-bad.HowESee
https://freeimage.host/i/0058-good.HowEUmu

It's not just at this timestamp though, it's the same problem throughout the whole video. Some seconds are worse, some are better (on YT). On local file (played with VLC) everthing is fine throughout the whole video.

I will do some tests with your settings, thanks for the input!

@sven-m8681

Wow, that is really bad, isn't it? I think that's YT's fault. It could be that the very rapid/jumpy video is causing the YT encoder to do such an awful job, creating bad artifacting.

Given it's 1920x1080 video, I would increase the VPX export bit rate to 4 times what you used for the original upload, as well as 2560x1440 for YT VP9 codec, and see how that goes. It might end up being a pretty big file.

PS: I couldn't open the "HowESee file until I put a : between the HTTPS and the //. Could you check that link code.

@sven-m8681

Good morning.

I swear last night I did not see those types of artifacts anywhere. Looking at it this morning it is blatantly obvious.

While I agree with @AAProds assessment %100 another way around this is to produce the video but change the GOP structure to all I frames but keep the Maximum GOP length. The first thing that should do is stop any further compression of any frame when re-encoded within MS or VPX if you set a high enough bit rate.

Secondly, when YouTube use their normal compression there should be less changes in compression of the frames that are currently being overly compressed.

This tends to work for me even if I don't upload at a 4K resolution.

Ray.

CubeAce wrote on 12/15/2022, 4:31 AM

@AAProds

Looking towards the end of that clip there are also signs that maybe the bit rate should be set higher as well as there is a lot of compression going on in larger areas or colour.

Ray.

AAProds wrote on 12/15/2022, 4:38 AM

@CubeAce

Ray, yes, I've suggested increasing the bitrate by a factor of 4.

johnebaker wrote on 12/15/2022, 5:14 AM

@sven-m8681

Hi

As @AAProds has suggested the issue is the YT conversion from what you uploaded - viewing at 1080p the artefacts are still visible in the 00:55 and 01:05 section.

What was the original screenplay or recording resolution and framerate?

If 4K UHD 3840 x 2160 then export and upload at this resolution to YT.

If FullHD 1920 x 1080 then the small upscaling change Alwyn has suggested may make a slight difference.

However . . . . increasing the bitrate by a factor of 4. . . . . , is, IMHO, an excessive amount if you used the default export settings for the resolution and framerate of the export, given the degree of 'flatness' ie limited detail and colour range in the badly affected sections of the video.

See the YT upload recommendations here, and do note that YT will create various lower resolutions, as low as 240p, of the upload for those viewers who are on slower Internet connections

Hallo everyone
@johnebaker @AAProds @CubeAce

To keep it simple I'll try to respond to all of you in one message.
First of all - thanks a ton for your time and your help! I really appreciate it. Special thanks to AAProds & CubeAce one of your solutions worked <3

I am still a bit confused though... (because the settings that now work are nothing even close to what is actually recommended by Youtube)...

Johnebaker posted the recommended Youtube upload settings (here). I did check those as well before and tried to upload with these exact same settings. Result --> horrible quality like discussed before.
@johnebaker I did check that the video is actually being played in 1080p and not in one of the lower available resolutions, but thank you for the good input. Just FYI --> the original game resolution is 1080p (1920x1080) FullHD and I tried exporting in MVP with different settings. Using the presets of MVP as well as using the settings recommended by YT (your link above). Nothing worked unfortunately.

@CubeAce & @AAProds
Thanks a ton to both of you. I had to combine the suggestions you both made to find a solution.
First I uploaded the video with CubeAces settings (/15000/50/I Frames only/High/5.2/Best) - with 1920x1080 (FullHD 1080p). I still had the same results...

Then I read then tip from AAProds and used slightly different settings (/15000/60/IBBP/High/5.2/Best) BUT with 2560x1440 (1440p). AND BINGO, it worked, my new uploads are now clean...

I didn't know that it's possible to export in a higher resolution than the native material was produced in.
To be honest, I still don't fully understand why the resolution made the difference, is it just because YT is forced to use the VP9 codec then?

ANYWAY - THANKS A TON! <3
Have a great day everyone

Pleased to hear the video is now OK.

Hey Ray, you're very welcome haha, anytime 😁
You mean the "lily" cover (original from alan walker) or the one from "KEiiNO" (just curious 😀)

Normally I'd include all that into the description, but those were more tests and for my friends than for anything else. But I think I'll still update the description tomorrow, thanks for the reminder 😇

cheers!

Hi Sven.

I meant the KEiiNO track, Nights of Thunder.(took me a good five minutes of searching) I can't get that track out of my head.

Probably the best new track I have heard this year. Alexandra Rotan has a wonderful voice. I may become a fan. I will be listening to more of the album.

Happy holidays and editing. You are certainly in the right country to enjoy the festive weather.👍

Super nice to hear that, it's always amazing when you find a song you really like!

To be honest - the song was suggested to me only about a week ago on Spotify (songs you might also like or something like that, the Spotify suggestions) and instantly fell in love as well :)) I didn't know them before either. She has a beautiful voice indeed. I definitely will check out the other songs as well.

Same to you! Thanks again for the help! Sitting in Switzerland here, more rain than snow usually, but today it's all white outside, so yeah! Festive weather incoming wuhuuu!

I've been stuck indoors for a week due to our festive weather which is now rapidly thawing. First day out was today. We don't tend to get gritters or plows in our area and it is very hilly in this part of the UK. I think KEiiNO picked the best track to put forward but some of the videos are good. Will be attending the first annual Santa Fun Run on Sunday since the covid lock-downs.

I did that for one that never happened.

Ohhh damn, didn't think that you could get stuck like this in the UK...
yeah agreed, seems to be their best song so far. Unbreakable sounds somewhat similar and is kinda nice too, but not as good as the other one.

Hope you had fun, looks like a pretty cool event in your video, too bad that one never happened though!

cheers & have a great week!

It gets worse - in the past 2 - 3cm of snow can, and has, brought many parts of the country to a standstill. We do not have such things as winter tyres, or many snow plough/gritters in areas such as the big cities and some coastal regions.

Hi Sven.

Well the charity Fun run went ahead but it was so cold, less than half the expected participants arrived and most of them were for the serious 10k event. Less than a third were actually dressed as Santa. The serious runners went first for the 10K event and by the time they finished the event had run over time so the Santa run was cut to one lap. In all a bit disappointing and because it was so cold my camera lens focus slowed and over two thirds of my images are out of focus. Video fared slightly better but because the run was only one lap I couldn't do my normal thing of cutting through to different sections to get a lot of different angles and shots together. I'll have to see what I can do with the resulting images and footage. That was 9am yesterday. By 7am today the snow has completely gone.

Actually it is very easy to get winter tyres in the UK but because they need to be kept on another set of wheels and we don't often get even a weeks worth of snow most years in my part of the UK (South East) and it would cost me about £1,500 pounds or more for a set and costs for storage and changing them, most people don't bother. UK housing on average tends to be small and most people have to park on the road. Although I have a garage it is not really large enough to change a wheel in. I prefer to use what space I do have in there as a general workshop which is behind where the car is rather than to the side. Most town house garages like my own are about 8' x 16'.

Also major roads do get gritted but a lot of the side roads don't. If you can walk to a main road you can get local buses for transport but forget using a car. Medway has 19 gritting lorries and also uses local farmers to cover around 11 square miles of mainly an urban road system that are tightly packed roads and housing, but the amount of gritting material in stock is limited so the council will only grit when there is actual snowfall which is often too late.

Have to agree on the music tracks.

Ray.
