Square Artifacting after uploading onto youtube

I've Got It
*update in post #8*

Hello Hello. So I have been struggling to battle this issue for quite some time.

I have an issue where once I uploaded a video onto youtube, I get these blurry blocks that appear whenever there is movement on the screen or flash/explosions. It is pretty bad at 360p, slightly better at 720p, and it is "passable" at 1080p.

I use Dxtory to record gameplay . Game footage is recorded at 30fps and depending on which game, 720 or 1080p. Dxtory spits out avi files.

Then I edit and render using sony vegas. At first, I tried to render from avi -> main concept avc/aac (mp4, avc), but apparently that caused blurry squares to appear in fast scenes. My settings are the same/similar as the vegas tutorial that is stickied in this subforum. So blurry blocks appear before uploading to youtube.

Since that didnt work. I then tried editing from avi -> wmv, which is fine.. but when I upload onto youtube, there is overall quality loss (but not as much blurry squares). I expected a quality drop since I am changing the containers from avi -> wmv -> youtube changes it to mp4. I did this for a while and now I want to improve my video quality.

So back to the square blurs (I think the term is pixelation artifacting?). I tried fiddling with the render settings like changing between variable and constant bitrate, using various containers and formats, turning off resampling. It was to no avail. I also rendered using H264 and the rendered video is very nice, but for some reason it is not that great

I am kind of stumped. Anyone have any idea on what may cause them?

For example, below is an example of the blurriness you'd see at 360p. You can see the squares on the guy's red jacket and the grassy area at the middle.

Well, 360p would be blurry when you stretch it out :P
I'd suggest using a lossless codec when you are recording, if you are not already doing that.

Oops. I used the wrong screen shot. Haha. I'll replace it now.

Well, Ut Video codec is supposedly lossless. One of my youtuber friends suggested that. Would the codec used to record affect the end product (post upload)? I mean, it looks great after render. Just looks poopie after upload.

I suppose I will try another lossless codec like Lagarith after work tommorow, but I would be very surprised if it actually improved the end product.

It is kinda strange I talk about 360p, but I notice my 360p looks bad compared to other 360p. My 720p is not that great either. My 1080p is not bad, but I suspect most people watch at 720p.

Actually, I watch a majority of videos in 480p. But what I'm seeing on your channel looks like a regular 320p video. :P

Maybe I am seeing issues that are normal. @_@ Since one is sometimes the most critical of one's work.

It just bothers me a little bit. haha
 
That happens alot in Sony Vegas because of smart resampling. Deactivate it. I have a video on my channel that explains it better. Basically you go to where your video is, right click,switches,disable smart resample. Try that and see if it works.
 
I hate to bump this, but I never solved this issue and I just went on to play slow paced, non high detailed games. But here I am again.

It usually occurs at high action and/or high detail parts of the footage and usually on the same spots.

So I spent a good 30 hours+ in the last 4 days trying out over 110+ rendering permutations on the same 2 test clips I am using to stay consistent and uploaded the ones that came out fine. I tried fiddling with bit rates (constant, vbr). I tried different containers/encoders such as h.264, wmv, and various mp4 formats. I tried on adobe premiere, sony vegas and a few obscure editors. I also disable resambling and what not. I used fraps and I used Dxtory with Lagarith Lossless codec.

I managed to get the best render quality by using sony vegas to render a part of my raw, which was 4GB for a 1 minute and 33 second video (as if I was done editing), and I rendered it at 50,000,000 bps (50,000kb). It produced a 538 MB mp4, which was pretty clear. Then I used handbrake with H.264 to reduce it down to 113 MB mp4 file. Also, this is not what I usually do. I usually use WMV.

However, it goes to hell after uploading the 113 MB file to youtube. You can see it at 0:30 and 0:40

I also tried uploading the 538 MB one, which was 50,000kb bit rate and It still occured.

I can somewhat mitigate it a little by turning my raw 1080p footage into 1440p rendered and then uploading it. The blurry squares is a little bit less noticeable when watching at 1080p, but its the same crappiness under 1080p. Most people probably watch videos in 360p and 420p because of auto settings... MAYBE 720p. I almost never watch 1080p videos even though I could, so this mitigation is not that goood. The video below at 1440p, watch the video at 1080p or higher and then at lower res. At lower res, it appears on the same spot as the video previously mentioned.

When I download the offending videos from my video manager, the blurry squares are not there or a lot less noticeable.

I don't really understand, I've watched and read dozens of "best rendering settings for 1080p youtube" and tried to research what I think is wrong (macroblocking, compression artifact, or whatever the hell they call it). I researched both MP4 and WMV render settings. MP4 seems to be most popular, but I don't know why I am having such a hard time with MP4. I am at a point where I am frustrated seeing people's 360p videos looking better than my 1080p. I get it more often and more serious on MP4 than on WMV.

Anyone have any ideas on how to make youtube not wreck my video? I THINK it is either youtube or somehow the transit between me and youtube went poopie.

I apologize for posting the video links in advance, but it is easier to see than to explain it.
