Thoughts on my MainConcept render settings for YouTube?
Hey there, everyone,
Long-time lurker now looking for some feedback on any thoughts related to my render settings for YouTube videos! After lots and lots of testing based around YouTube’s recommended specs, I’ve settled on the following settings in MainConcept (I know the maximum bps is a bit overkill, especially for CPU rendering, but I’m fine with the extra rendering time/larger file size for the quality difference):
The only “problem” I haven’t found a solution to is how inconsistent everything ends up at 1080p on YouTube. No matter what I render with or how near or far I am from YouTube’s specs, 1080p inevitably looks pixelated more than it seems like it should at times; however, for all I know, my MainConcept renders are giving YouTube the best possible thing to work with and it’s simply not going to get any better than the results they churn out with their internal render settings right now.
Here’s an example of a final product, on YouTube, 30FPS @ 1440p and lower (after it starts playing, you can modify the resolution and then full-screen it in the bottom-right-hand side of the player):

It looks great at times, but blurry/pixelated at others. I’m just wondering if there’s anything better I could be doing, perhaps based on personal experience from those of you who have worked with rendering videos for YouTube.
Thanks for any feedback you might have!

The MainConcept encoder doesn’t allow you to change the Entropy encoding which YouTube specifies and being CABAC. You might try using the Sony AVC encoder which does allow you to change this setting.

John,
Sony decoder has CABAC, but it cannot do 2K that OP seem to want.

Silly, me… why would the Sony encoder support the Sony project formats? What was I thinking!? lol (good catch)

LOL! Thanks for the response, guys.
John, since YouTube currently only supports 60FPS at 1080p, I wouldn’t mind trying the AVCHD/Handbrake route; however, do you know of a method in Vegas that I could use CABAC entropy as well as a bit rate above 25Mbps? 50Mbps is what I’d like to shoot for, since I’ve seen the bit rate spike higher than 25Mbps on YouTube playback of 60FPS HD videos.
From what I’m seeing, it looks like I may have to start messing with methods outside of Vegas, but the question is if the gains will be noticeable enough to even worry about it (I’m all for testing, though, so I’m up for it!). I’m just looking to achieve as little pixelation as possible after YouTube’s encoding of my upload.
Could CABAC at 25Mbps produce noticeably better results on YouTube than a much higher bit rate with non-CABAC encoding? *Cue Tootsie Pop commercial* “The world may never know…” lol.
I may just have to do some testing to see. Thanks again for the feedback, and happy new year, all! =)

Since Youtube re-encodes everything you upload, if the file you upload looks good but the Youtube result is bad, then really there is nothing you can do. The Youtube encode is the limiter and not what you are giving them.
High detail with motion is problematic to encode and consumes a lot of bitrate. Internet delivery is very bitrate limited.
Youtube encodes to an average bitrate and the bitrate can spike within constraints. Having infrequent and brief high detail motion sequences may be handled but too much and things start to break down.
With Youtube you can get bad quality or great quality. That depends more on the content of the video, which determines how well it compresses, than it depends on the quality of the encode you send them.

[Stephen Chapman] “do you know of a method in Vegas that I could use CABAC entropy as well as a bit rate above 25Mbps? “
No. It’s unfortunate that Vegas has 2 MP4 encoders and each have 1/2 of what you need but neither have it all.
I noticed that you don’t have the 2-Pass option checked. You will get much better quality of you use 2-Pass. In fact, you can use a lower bit-rate with 2-Pass because it will make better use of the bits you have. Try this and see if it fixes your problem.

[Norman Black] “Since Youtube re-encodes everything you upload”
This happens with the audio too… YT resamples everything to 44.1kHz.
Also, I am not sure if is a local streaming issue, since I cannot see artifacts in the above video.
Stats for nerds reports the format as DASH/VOD:
