Youtube pixelation Problem :(

Hi,

I'm using Adobe Premiere for a few years now.

In the last few months my uploaded videos looks terrible, especially when the scene are changing fast and are different from one another.

Here is clip from the last few days demonstrating the problem.

Speed Flying - Flip 360 FPV QUAD (2 min 49 sec)


The problem is extremely visible in 01:25
Please If you experience the same issue - respond if you have a solution.

Anyone ?

Use Vimeo instead. Youtube has always compressed videos. Vimeo does not.

You are most likely choosing their stabilization process? If so, don't and process all fx internal before uploading. What format are you shooting in and what are you exporting as? Worst case, re- upload it could have been corrupted.

Thanks for your responses.

Waterbound:
I never choose their stabilization - its horrible, makes your video looks like rubber sheet.


I use the following Adobe Premiere export settings:

Format: H.264

Output: NTSC, 1920x1080, 29.97 fpx, Progressive
AAC, 160kbps, 48 kHz, Stereo
VBR, 2 Pass, Target 25.00, Max 25.00 Mbps


Profile: High
Level: 5.1

Render at Maximum Depth = Checked !

Use Maximum Render Quality = Checked !



Now I'm just speculating here but maybe YouTube downgrades streaming quality for non popular videos?

I know Vimeo is much better, but it is annoying that other users on YouTube get really good video quality.

Personally, I have never seen YT prioritizing for popularity, I have several vids posted private that render nicely and were posted as 1080p with no pixelization. But interesting thought on their prioritization if it's true.

I looked at this video again

DRQ 250 aka "MINI D" - Forest Flying (4 min 57 sec)



At first it was unwatchable - especially when the scene changes (All pixels)

But now I think there is an improvement, so maybe over time it will get better ?

Please take a look and tell me if you see the problems.

Choosing VBR and having max and target bitrates equal isn't good choice ;-)
But 25Mbps should be more than enough anyway. And yes, YT sucks a lot, they lowered HD (1080p) several times.

Examples:
My old comparison video has ~9Mbps avg bitrate, with peaks up to 90mbps (!!!):
Mobius standart ("classic")/Mobius Wide/GoPro 3 Black/HoryzonHD v2 lens comparison (6 min 47 sec)

With time video average bitrate become lower, lower... And peak bitrate is low even for fast scenes. Uploaded few days ago:
Picking mushrooms with PocketRocket - sunny autumn... (4 min 37 sec)

Average bitrate ~4Mbps (wut???? HD?), peak bitrate approx 6.5Mbps (for fast-moving scenes).
Both are for 1080p playback... Something wrong happening at YT :/
Some ppl are doing 4K hack, but this won't work for all, so hm. Back to vimeo?

Nice Flying !

How can you tell the video bitrate once uploaded to youtube ?

Well, bad export settings will make video even more crappy ;-)
Some ppl talk about compressing dynamic range before YT, also - go with CBR if you're doing max and avg bitrates equal...
Keep at least 20Mbps if exporting with premiere (not default YT preset), this also helps.

My videos on youtube is barley watchable with all the pixelation and bad bad bitrate.

No matter what my export settings are

FPV Quad - Highlights - 2015 (3 min 32 sec)


It is terrible and making the whole concept of video sharing useless.
I still wonder how some channels doesn't have this problem at all.

How well does the raw footage playback on your computer? Wondering if some of it is just the fact that Cmos sensors and HD and fast pans or flying= crappy footage

your asking a lot for a 500 dollar video camera

It's perfect - on the PC - sharp and clear with 100% details.

The quality of the camera in this case is irrelevant, the problem lies in the youtube automated encoders.
