x264 and PPro CS5
I’ve been reading and reading and I’m trying to still figure out the best way, or even how to use x264 in conjuction with Premiere Pro CS5. The reason I’m looking to use x264 is because I am unhappy with my results from the main h.264 profile.
My edits are perfect and rendered in timeline. When I go to encode for youtube HD, I used Adobe Media Encoder’s preset for it but I increase the bitrate to VBR 2 pass, and target 8-10mbps.
Im still getting artifacting. Why? And I knows it not youtube because I’ve seen people use the same camera/res and get crystal clear videos. I have a decent system, core i7 8 gigs of ram, windows 7 64 bit…
Am I doing something wrong when I encode? Any help would be greatly appreciated.

The artifacts you are seeing – are they in the encoded video before you upload it to YT, or only on YT once it’s uploaded?

A little bit of both, but most of it shows up after once it’s uploaded for youtube..
I was told by a friend that Youtube doesn’t like a lot of intense water. My edit has a lot of that..Anything I can do?
It looks good, but man I want it to look as crystal clear as others videos Ive seen on youtube..
I feel like im close

It’s probably due to nearly any codec not liking lots of details with fast motion – which is hard to compress efficiently, and YouTube, in the interest of saving bandwidth and space, may lean towards higher compression (and artifacts) rather than quality. Even YouTube 4K videos have artifacts at peak bitrates of about 55Mbit/s.
You could try to “clean” your video by reducing (filtering out) luma and chroma noise which may affect the end result.
You could also try raising the ceiling on your target bitrate to, say, 15Mbs and seeing if that helps.
By all means, do not upload the entire clip – make a 5-10 second sample containing the most affected footage that gets the most artifacts, and try different things with that, uploading it as “private”.
Also, do take a hard look at the videos that you say are squeaky clean and smooth – do they have as much detail and motion as yours? Try contacting the uploaders of those videos and ask them what their secrets are, i.e. encoding settings.
Another thing to try is to upload to other services such as Vimeo – which or may not allow higher bitrates in videos.

Wow thanks for the very constructive and very thorough feedback! Much appreciated. That 4k tidbit makes me feel a bit better about whats going on..
Im going to send some emails out tomorrow to some of the people that made the vids I like and do just that, ask what their secret encoding sauce is. Hopefully get some good results.
Thanks again for your response, defiantly going to try some of that out

Just a thought: Are you uploading the same size as YouTube displays? If no, try that. If yes, try uploading a larger (pixel-dimensions) clip. It might make a difference in the (re) compression. I think when I have done YouTube uploads in the past we limited to 6K Mbps or lower. There might be a ceiling under which there is no recompression applied? (I’ve tried to find specifics from Google to no avail)

Yes I am.
My footage is 720p @ 23.976 – Uploading it with the same specs to Youtube. Yea I wish youtube encoding info was more public, like the best combos.
Im currently using 2pass VBR. Target 8mpbs, max 10mpbs. The PPro CS5 preset for youtube hd is 6mpbs..but I thought that was a little low..
