Help! I Can't Get Good Youtube Quality!

Alright man, I just got my first action camera and I'm getting seriously demotivated already. The camera that I am using is a Vikeepro 4k Action Camera. It is not a real GoPro, but the camera is not the problem. The videos themselves are recorded in 1080p 60fps, and they look absolutely stunning in their raw form. The stock footage is .MOV format with a bitrate of roughly 35k. I edit/render videos with Sony Vegas 13 Pro.

I record my videos, transfer them to my computer. They look amazing, extremely clear and smooth. Now I import them into Sony Vegas. I've tried rendering my video with a ridiculous amount of settings, and I never receive a better result. Once it is uploaded to YouTube, it gets blocky and full of artifacts and it drives me INSANE.

I have tried uploading in MP4, AVI, and MOV formats, no change. I've tried variable and constant bit rate, 2 pass encoding, matching bitrate to source, changing profiles in vegas from main to high, compressing with handbrake, using deblock and deinterlace. No matter what I do, I can never get my video to stop showing these pixelated artifacts. I've tried rendering in 1440p and 4k for a higher bitrate, no change. I just can't figure it out.

Here is a prime example of the blocky artifacts that occur: ( video link blocked. I can email an example)

You can see that the road becomes extremely pixelated right after the video starts. I can upload screenshots of the same exact video time on my local files, I can show you my Vegas settings that I have copied from over ten different online articles to get a better result. Please explain this to me.

I need your help. My video quality makes me not want to upload and that is an extremely shitty feeling.

I have tried at multiple locations, and friends are seeing the issue as well. Plus, my internet at home is 300mbps.

I have not seen a format optimized for YouTube on Sony Vegas :/

Setting it straight: The quality is 1080p 60FPS on a fully processed video, playing on YouTube. I'm not sitting here looking at a video I just uploaded, seeing it in 360p.

If I match the bitrate to the source, it's at roughly 35k. I've tried rendering in 150k, so over compensation isn't doing me any good.

Unfortunately I can't post links yet, according to forum rules. If you guys know a workaround for that, please tell me. Otherwise, I can email you the linnk to the video, and even to the specific time where I see the issue occur. I've heard that 60fps is hard to accomplish on youtube, but I've definitely seen it work out well and it looks clear as day compared to mine.

Here is a great example of the issue at exactly 1:36!!!

the raw footage looks great on my local machine. The camera quality is amazing, no grainy texture, no pixelation. I just uploaded a long ride that some friends and I took on Sunday, and I decideed to record in 30 fps this time to;

A: save battery life for a long ride
B: Hopefully see an increase in clarity due to the smaller framerate.

I was thinking that the 60fps was causing the issue, but it persists in the 30fps footage on Youtube.

Once again, looks GREAT on my local machine.
