Uploading to YouTube (HD Platinum 11)

Hello,

I've got a project which I can successfully upload to YouTube via the 'Make movie' wizard - as long as I choose 'Normal' for the render quality. Selecting 'Higher' causes the process to fail with a '400 - Bad request' response from YouTube during the upload stage.

Would appreciate any pointers on how to get this working. Alternatively (and preferably), I would like to render the video with the same YouTube-high-quality settings, but I don't see a render template specifically for YouTube in the list of options - is there one?

Thanks very much in advance for any help.

/m

Since Youtube is constantly changing its APIs, we recommend rendering your video in Vegas and using Youtube's upload service.

I don't know what the Make Movie option does, but there is a tested Mainconcept template near the beginning of our Youtube tutorial (the "Good Method") that can be seen here.

Thank you for the reply (and great video).

I tried out the 'good' method but the file it produces is much larger in size (about double), taking very much longer to render, compared to the "Upload to YouTube" wizard.

Perhaps I've made a mistake copying the settings from the tutorial somwhere. Wish I could determine the setings used by the wizard so I can apply them myself, though!

Thanks,

No you haven't made a mistake.
My tutorials are tuned for optimum quality, and not file size or rendering time.

The "Good" method is 8Mbps vs. about 4Mbps from the wizard = much better quality = double the file size.

The "Good" method is 2-pass VBR vs. Single pass from the wizard = much better quality = double the render time.

It's just math, and how much quality loss you are willing to endure for the sake of smaller file sizes and rendering times, which make very little difference once it's on Youtube.

On the other hand, our tests establish that 4Mbps from Sony AVC is significantly worse quality for videos that contain motion and transitions than 2 pass VBR at 8Mbps using Mainconcept. Those differences are magnified once it's been processed yet another time by Youtube.

But if you want to emulate the "wizard"settings, just download MediaInfo, analyze your files, and duplicate the settings.

Hi musicvid,

It might be a combination of my source videos (essentially of lectures being delivered, perhaps not terribly visually complex or exciting!) and my own newness to video processing, but I could not discern much difference in the output between the 'good' method and the wizard. The rendering was also taking much longer - like 5 times more.

I'll try out MediaInfo as recommended and see how that goes.

Thanks again for taking the time to share your knowledge with everyone here.

Your observations are correct once again. The areas in which differences between average bitrates can be easily seen are in videos that contain lots of detail and high motion combined, not at all like the ones you describe. So the "wizard" may be just fine for your purposes.

If we go all the way to the other extreme, slideshows without motion rendered using AVC reach optimum quality at around 160-200 Kbps, at least 20 times smaller than normal motion video. That is the nature of intraframe compression using some of the more recent innovations in compression.

You can see some good low-bitrate examples on Jerry's tutorial site here, near the bottom of the page:

The reasons for longer rendering times is the second pass in Mainconcept, which also improves the detail-in-motion quality factor.

When you get the properties from MediaInfo please post them here so we can see what the Vegas YT wizard is really doing.
