Sony Platinum 10 HD Settings for Vimeo/Youtube

jtlessons wrote on 8/13/2010, 9:34 PM
Hey, my test upload is ok. I am shooting in HD with my Logitech 9000 Webcam. Then processing the file with Sony HD 10.

I am selecting: Main Concept AVC/AAC .MP4 then Custom: 1280x720, (Do not understand "Allow source to adjust frame rate or frame size??)

Profile: Main, Frame Rate: 29.970000, Feild Order: None,
PAR: 1.0000, Number of reference frames: 2, Checked Use deblocking filter, Using Variable bit rate Maximum bps: 8,000,000 Average bps: 5,000,000 Audio: 44,100hz with 32,00bps.

My videos are Guitar, Bass & Ukulele instruction and need to be the best I can make. On the Project tab should I select "Best" for quality?..makes sense.

Anyway, here is the test. Just want to learn how to do it right. I am not a video editor so looking for help with settings.

"Using Variable bit rate Maximum bps: 8,000,000 Average bps: 5,000,000'

Youtube processes it down to 3Mbs, so feeding it anything over 4Mbs is overkill and takes longer to upload. Keep it 3.5 - 4Mbs.

EDIT: OTOH, your Vimeo download came back at the full 5Mbs, but only 15fps? Maybe your webcam only shoots 15fps? In that case render at 15fps.

Also, you should run your Mainconcept files through MP4 FastStart before uploading (saves processing time on the server).

Actually, this is not true. The more quality you have in the source video, the better low-bitrate transcode will be on Youtube/Vimeo. Both sites re-encode at 2 mbps VBR for 720p. For 1080p they re-encode at 4 mbps VBR. However, if the footage you're feeding their encoder is crappy, you will indeed get worse results. The 5mbps avg/8mbpsMax is a good number for 720p, it's what I used for a year with good results. However, lately I encode at 8 mbps avg, and 16 mbps max, and the results are a bit better.

For 1080p encode at 12 mbps avg, 20 mbps max.

Actually, I checked my facts before posting.

First, I want to be clear that I am speaking about the actual, highest quality downloads accessible on the Youtube and Vimeo servers (the latter directly), and not what shows up in the player or in one's browser cache (which are of only cursory interest).

25Mbs 1280x720 AVC uploaded to Youtube comes back "HD 720" 3Mbs mp4 downloaded from the server.
Complete name : C:\Users\******\Desktop\Ducks 1yt.mp4 4Mbs 1280x720 uploaded to Youtube comes back 3Mbs "HD 720" mp4 downloaded from the server (you can take my word).
Youtube's resampling is about the worst there is, but I will concede there is a slight difference between the 25Mbs and 4Mbs results in areas of static detail, but not motion artifacts. They're both sad.

Vimeo, otoh, makes the original uploaded file available for download (if you permit it), a nice feature.

As for the rest, I would never upload 1080-anything to Youtube!
Why? Because it is processed as interpolated 540i or something to that effect; i.e., half the vertical resolution is discarded

But Youtube HD 720 is displayed at full vertical resolution

**Many thanks to A. Grandt for making his original tests and files available.**

The last thing I should mention is that Youtube will also bump everything you give it from Studio RGB to Computer RGB, whether it needs it or not. So for predictable playback levels you need to feed Youtube Studio RGB (16-235) only.

(Please forgive the incorrect abbreviation in advance.)

I am half way into a almost 3 hour render of a 14 minute video using the settings I originally posted.

The .wmv file size is: 794MB will it get bigger after rendering it to .mp4? I will have a answer in a hour....

Also, when I look at the details of the file it is showing a frame rate of 15 per second? Will this be increased on the rendered version?

I may have to shoot in lower resolution to get 30 per second.

Why are you starting with wmv? Is that all your webcam will allow? I thought your example looked a little flat . . .
There is no way to increase the frame rate of captured video. All it will do is duplicate frames.
I would choose higher resolution over frame rate, if that is the choice.

It sounds like your webcam may be the weak link in your workflow.

It is looking that way. Thanks for your help man. I spent all day trying upload the 700MB file to Vimeo only to find the audio/video out of sync once it went through there conversion?!

I am going to try rendering it again with your recommended settings.
I will put the frame rate at 15 which is what the webcam shoots in and up the other settings you said to boost.

I am also going to try using the webcam as a capture device from Sony Vegas Platinum 10. I hope to be able to get a better frame rate doing it this way.

Why is the video ending up so out of sync once it goes to Vimeo?
I am also going to try MP4 FastStart on the final before I upload.
