  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

YouTube Video Codecs, Resolutions & Data Rates

As I said, just switch to HTML5 player and everything will be just fine. With HTML5 player Vimeo uses correct file at full resolution and not the Flash abomination.

Both the Flash and HTML5 player are displaying the video at 1280x544. Don't get mad at me; it's not my fault. I'm just stating the facts. :-)

Besides, it would be impossible for the HTML5 player to work and the Flash player to not work since they both reference the same MP4 file. The HTML5 player just uses a different player based on the HTML <video> tag. That's less process-intensive than loading the Flash elements.

Try this: Go to http://www.savevideo.me/, enter the URL of your Vimeo video and download the file to your computer that way. What's the resolution of that downloaded file?
 
Jake, it looks like you just recently checked the box because Vimeo is only now saying that the new HD version of the file is ready.

I'm waiting for it to refresh now.

My apologies Brian, my bad:-)
The checkmark "display this video at 1080P" wasn't checked. I was looking at the wrong video all this time. I just checked it and it will take a little while for the video to upgrade to 1080P.

No worries. =D


By the way everyone, I just received the results for another test. YouTube does not support Apple Intermediate Codec. I'm waiting now for the QuickTime Uncompressed 8-bit and 10-bit files to upload.

Hm, that's a dilemma with Windows platform. DNXHD doesn't support 4k yet. So, if I were you, I would use Windows command line tools to create 4k Prores on Windows. I haven't personally tried it, but I understand it's quite easy and I'd been told, that there is even a GUI app for that. But if you have a Mac, just render as DPX and transcode it to prores on a Mac.

Thanks I found it all for windows ,work ;)
I go out in DPX 16 bit and convert to ProRes to 4k or 5k and then load in 4K on youtube;)
Jake thanks for the tip.

A couple of days ago Image Systems provided me with a demo license for Nucoda Fuse. It is running on Windws, it's fully 64 bit app and the best part, it writes any kind of Prores, including 444. And on top of that, they even fixed the gamma shift. That is impressive. Would like to see something similar in Resolve on Windows. But somehow, I doubt it...

Hopefully, maybe the guys at Blackmagic will make us a surprise with the final version of Windows, i hope;)

No, I do not.

Okay. In the comparison between the YouTube version at 1080p that you uploaded in ProRes and the Vimeo version at 1080p, the Vimeo one looks better. It has less blocking and noticeably less compression artifacts.


So, for people who want to upload a 1080p video and who have Vimeo Plus, upload it to Vimeo in 1080p and make sure you check the box so that your video will be display in 1080p. For people who don't have Vimeo Plus, upload to YouTube in 1080p. And, for people who have files that are larger than 1920x1080 (anything between 2K to 4K) upload to YouTube.

More test results coming soon.
 
Brian,
I forgot to say before: You might want to add some grain in you test images, say on the right half. Grain is the dilemma for all codecs to deal with. It's all about preserving the grain.
If you want to get 'fancy' you can digitally compare the original with the compressed, and look at how things are preserved.
In the industry we use a term : PSNR , to quantify the quality.

BTW, late next week I may be organizing a get together at my work, to review and rerun my DSLR vs Scarlet finding I have mentioned before. I'd like at least 4 users to attend.

Regards,
-Les Dittert
