Looking for .PRX file good for YouTube HD
[Post New]
I've seen a few posts about this, but they came short of actually nailing what I think some folks are looking for, which is:

Has anyone been successful creating a new .prx file for the Profiles folder which allows a PD7 user to create a video file that has a high chance of getting the maximum quality when uploaded to YouTube and it's new "HD" viewer and aspect ratio?

Dafydd! My brother! I'm guessing this would something you might be able to do without too much trouble? I thought I saw you say you wanted to create a video which shows this? If you did, I'd certainly like to watch it and learn.

You can alter the profiles for WMV files. Dafydd has a video tutorial on how to do this. Its very easy, and once you do it, they show up in the list as a standard choice for you to select next time you render.

Youtube will take almost anything sized 1280x720 with a bitrate of at least 2500Kbps and make it HD.

Trouble is, WMV files render pretty slowly. Win8 64-bit Pro Retail
Intel i7-4770
16GB DDR3 1600 8-8-8-24
MSI Z87-G45 Motherboard

1 TB RAID 1 (mirrored) Drive Array
Several scratch drives for video, TMP, pagefile.

Thanks for your reply. I have used before the information Dafydd provided in order to create new .prx files. It works well, and it helps me in the past a great deal when I need to modify resolution, audio quality, and such things. That is, using the Windows Media Profile Editor.

But as you know, there are many variables to set. I guess what I was really looking for was to see if anyone created the perfect recipe, or even a very good recipe (in the form of a .prx file) for maximizing the quality of the video after YouTube's done doing whatever it does with what one uploads. Especially for the new player. By recipe, I mean the optimal parameters for res, frame rate, video bit rate, etc., and many others.

I mean I can continue my trial-and-error path, but I try to see if anyone has already skinned the cat.

But since you say that 1280x720 and 2500kbps vbr is all what it takes to make it the best, then I will go do so. It's just that I see some really high quality videos out there on YouTube now, and I fail to get anything to look as good, even if what I have produced from PD7 is 1440x1080 originally and it plays crystal clearly in, say, Windows Media Player. Then I load it to YouTube and it looks like junk. Do you know what I mean?

If you wait a bit, at least an hour, your video may suddenly have the HD option listed.
I've uploaded 2 Mpeg2-SD and 1 Mpeg2-SD rendered to 720, and all 3 wound up with the HD option.

Hi misaltas,

We recently did a lot of experiments for the Youtube tutorials. These were produced in wmv9 HD SQ but not all converted to HD in youtube.

I know that youtube are still optimising the HD side of things and are not very explicit about what formats and specs are best.

We went with a 2 stage process (I know that's not your question/answer but...) to produce smaller mp4 using the free software super© and this seems to pretty much guarantee HD conversion smoothly. Surprisingly, Dafydd produced a tutorial :-

As Barry says even rendering (or re-rendering) SD to allow youtube to display the HD player is beneficial. If you're interested, I have just re rendered a scuba video as an illustration :-

Barry, a kind and generous suggestion but I'll remain content with my good looks, vibrant personality, physical prowess (or was that a dream I had last night?), etc etc etc.

Thank you all the same.
Cheers

No, I would suggest that is the least that will reasonably tranform into an HD video on youtube, not necessarily the best quality.

I pretty much use a bitrate of 5000kbps because that's what Vimeo suggests and it works on youtube, too. If I had faster broadband to upload I would use a higher bitrate. Win8 64-bit Pro Retail

Wow, I would say so.

>>I know that youtube are still optimising the HD side of things and are not very explicit about what formats and specs are best.

YouTube surely doesn't make it easy, nor documents things that well.

Surprisingly. Yeah, nice. Sorry I missed that on my own, but I appreciate you pointing me to it.

That said, big cheers to Adrian for doing the heavy lifting for the rest of us sinners. Oh, big thanks to Robert J. for his work also as the end credits noted.

I followed the instructions in the tutorial to the letter and the HD result on YouTube is perfect.

And I'd like to add...

In case anyone searches and finds this thread later, that I create many of my videos by doing screen capture in addition to regular handheld camera stuff. I've determined that if I can do the screen capture at exactly 1280x720, not only does that match the 16:9 aspect perfectly, but it also reduces the pixel resampling that would occur if the actual H/W pixel size were something other than that.

And I cannot forget:

Dafydd!! What is that music on the end credits of the video? It's really trippy mannn...

Hi Misatlas, Bro

As you'd expect, I loaded the YouTube HD tutorial onto, yep even YouTube http://www.youtube.com/watch?v=5W-kStCfdgo

Music is good isn't it

Screen capturing tip is valid because the one video which we found had a problem with mp4 for YouTube HD had been overlooked and not "stretched" to 1280x720 in the first clip. We considered it a blip. Robert did get the mp4 accepted by raising the bitrate on the mp4, hence the advisement in the video.
