[Norman Black] “So you can look at someone else’s video and it seems fine, and you can use their exact encode and upload process, but it may not help your video because your source material is not exactly theirs.”
[Sebastian Hernandez] “What do you mean source material is not theirs?”
Your video is not exactly like the other one you are comparing to. Each frame in succession is not the same between your video and some other game video you are comparing to on Youtube.
Video compression in codecs like AVC/H.264 is highly variable and the amount of compression that can be done really depends on the exact sequence of video frames and how similar those frames are. The bitrates offered by Youtube/Vimeo are quite low and the get a quality level most would consider “high” your video needs to be capable of high compression. Otherwise quality suffers noticeably.
Most video game material has very jerky movement which is difficult to compress. First person type movement also is more difficult to compress.
I have direct experience first person movement. With my GoPro mounted to my mountain bike that is first person movement. My camera footage is crisp. My renders from Vegas are crisp. Internet video is only just okay. Stabilization helps in my circumstance.

One thing to always remember. If your encode from Vegas looks good but the Youtube result does not then there is nothing you can do. It is what it is.
Youtube re-encodes everything uploaded and their bitrate, like all internet video servers, is quite low and some source material just does not compress well enough to maintain quality. When the bitrate is not enough you see quality drop but then it usually comes back up when the source material compresses better.
So you can look at someone else’s video and it seems fine, and you can use their exact encode and upload process, but it may not help your video because your source material is not exactly theirs.
The “internet” templates in Mainconcept AVC and Sony AVC are a good place to start. If one wants a smaller file to upload, then going to x264 via Handbrake or ffmpeg or similar is another way to go. Not sure how much time this might save. With the former you can be uploading while with the later you need a second encode before you can start an upload. It depends on the size of the upload and your internet speed.
This site and others need a “sticky” thread at the top since this video game, low quality, Youtube result question comes up most every week.

[Paul Hinderscheid] “Under Mainconcept AVC what do I choose? Like Internet 1080p or Blu-Ray. Under the Blu-Ray one it’s not letting me include audio.”
What are you trying to do. Upload to Youtube/Internet or generate a Blu-ray? Hint, Hint.
If Youtube, then start with the Internet template(s) and adjust it as needed.
If Blu-ray then start with one of the Blu-ray templates and adjust as needed. The Blu-ray templates are designed for use with DVD Architect and do not render audio since you render the audio separately from video. The reason is that DVD/Blu-ray support multiple user selectable audio tracks.

The specs show about 20Mbps AVC video. So you can use Mainconcept AVC or Sony AVC at about 20Mbps average bitrate. Same frame rate and frame size as well. Use 160Kbps for the audio bitrate.
Understand that Youtube 1080 video is only about 8Mbps which is nowhere near 20. Uploading a 20Mbps video would be a bit of overkill. Rendering 20Mbps AVC from Vegas will preserve the original video about as good as possible.

Except for uncompressed video there is no such thing as “lossless”. All codecs are lossy, but I think what you are looking for is to encode with a setting that will have the same quality as your source encode.
The only straight forward way to do that is to use the same dimensions and same video codec at the same video bitrate. This is not truly exact because some encoders are better than others at equal bitrates.
You can use a utility like, MediaInfo, to get the specs on a video file. It is a free utility.
You mention 55 minutes at 899MB for the file. This comes to about 272 Kbits per second overall bitrate including audio. 899,000,000 / 3,300 seconds. This is a shockingly low bitrate to me unless the video dimension/resolution is very small. Could there be a typo here for the file size.
If you are uploading to Youtube then you cannot maintain the exact same video quality as normal Blu-ray encodes. Typically Blu-ray movies are encoded at over twice the bitrate that Youtube provides. Remember that everything you uploaded to Youtube is re-encoded to their spec, regardless of what you upload.

I agree with JR and I have done this once myself on a mountain bike video. It helped.
Really anything static from frame to frame will work.

One can use something like TMPGEnc to “smart trim” long media into smaller parts. It works on AVC LongGOP file formats. Of course cut points are limited to the beginning of a GOP but when you are just trying to trim the excess this is not a problem.

[Norm Kaiser] “But I render to meet the CALM Act guidelines, the audio sounds so, well, quiet. I have to turn my PC’s audio all the way up for it to sound good. And then invariably I get the little dingdong chime from Facebook that I just got a new message and my eardrums get pierced.”
Normal PC UI sound effects are typically coded near 0dB. Full modulated volume. Movies modulate average dialog level to say around -27dB, and this allows for major dynamic range so that explosion is really frickin loud compared to the dialog. TV specs seem to limit dynamic range with peaks much lower than 0dB for whatever reason but the average dialog level is still modulated to similarly low level.
So yes, amplifier gain must be turned to a value to get average dialog to a suitable loudness. Not a problem on TV and movies, but on a PC with UI sound effects modulated to a completely different “standard”, then Yikes! the beep can be frickin load just like that explosion in the movie theater compared to dialog.
edit: I would speculate TV limits peaks because TV speaker systems can be pretty cheap and once amp gain is set for good dialog volume the speaker/amp is not capable of extreme dynamic range and the sound would crap out. This is what THX did for theaters. It guaranteed that a theater sound system was capable of a certain dynamic range and certain volume levels. No such guarantee with TV speakers.

[John Rofrano] “I thought this was fixed in the last build. Maybe it got reintroduced? The problem only happened if Vegas Pro 13.0 was the first and only version on your PC. If you had any previous versions this problem didn’t occur so not everyone was affected and it’s hard to reproduce.”
I had the demo mode problem. I had Vegas 12 installed. Then installed Vegas 13. All okay. When I uninstalled Vegas 12 then I got the demo problem. If I reinstalled Vegas 12 then the demo problem went away. Reinstalling Vegas 12 was the official and only SCS support response to my bug report. Of course their response was a month after my report and I figured the reinstall out within hours of my report.
The new build fixes the V13 demo problem for me.

[Brad Leigh] “And my question remains to others since Vegas Pro 13 lists New Blue EFX, and spotlight is an EFX which may or may not be included in Pro 13. I’m curious as to the version if it is included.”
Vegas 13 comes with Video Essentials 6. That package does not include Spotlight. The Spotlight you have is a part of the starter pack that comes with Titler Pro 1 that you got bundled with Vegas 12.
Video Essentials 6, in Vegas 13 bundle, is no longer sold by NewBlue. They recently reorganized their product line. The filters in VE 6 still exist but are included in different product bundles.
