Sony Vegas Rendering Issues in HD

[John Rofrano]

I can’t see the video in your post for some reason. Youtube accepts 720p now so I would render your file using the Sony AVC render type at 720p. You have to make a custom template in Vegas Pro 8.0:

Render Type:    Sony AVC
Video Format:   AVC
Frame size:     (Custom frame size) Width: 1280 Height: 720
Profile:        Baseline
Entropy coding: CAVLC
Frame rate:     29.976 (NTSC)
Field order:    None (progressive scan)
Pixel aspect:   1.0000
Bit rate (bps): 6,000,000

Audio format:     AAC
Sample rate (Hz): 48,000
Bit rate (bps):   128,000

That should give you a nice looking video for Youtube. You might want to save this with a name like Internet HD 1280×720-30p @ 6,000 Kbps (Youtube). In Vegas Pro 9.0 there is an Internet 16:9 HD 30p setting that is exactly as above provided by Sony and you don’t need to use a custom frame size because 720p is in the drop-down list.

Good one John. Here’s what I typically use, just as another “fer example”:

Render type: Main Concept AVC
Frame size: 1280×720
Profile: Main
Frame rate: 24
Field order: None (progressive scan)
Pixel aspect: 1.0000

Variable bit rate: Two-pass
Maximum (bps): 50,000,000
Average (bps): 30,000,000

Audio: 48kHz/192Kbps

Some notes:
(1) I use Main Concept AVC because the Sony encoder was unreliable on my system (Vista64, Vegas 8 32-bit). When it did work, it was fine (never noticed any quality differences).
(2) I use 24fps for Vimeo which, the last time I checked, was distributing 24fps. I thought YouTube was too, could be wrong, could have easily changed in the last year. In any case, matching your frame rate to whatever YouTube is spitting out these days is the “right” frame rate to render at.
(3) 44kHz might make more sense for the audio, since I think that matches the distribution format as well
(4) Kick the bit rate up as high as you can. My segments are typically 5-10 minutes long, so I can get away with super-overkill-unnecessarily-high bitrates (although there’s some invisible ceiling and you can’t actually get 50Mbps). Longer clips will need lower rates to squeeze in under the upload file size limit.

Thanks for your help guys.

While you’re here – I’ll try posting the clip again with the crispness.

Also, sometimes when my files have been uploaded to Youtube, the audio is out of sync to the video, Youtube suggests I change the audio to a lesser quality format. Any suggestions?

Here is the link of the clear video,

And below is the respons the guy finally gave me to what he renders in:

wmv
HD 1080-24p (1920×1080, 23.976 fps)222
59.940 (Double NTSC)

Thanks again guys.

Youtube can be 24,25 or 30 fps. 1280 x 720 (max).

Bitrate from yuotube’s player something like 1.5-2.0 Mbps (HD).

So there is no need for more than 1-pass 5.0 Mbps rendering quality.
