    Default 9000 or 10000?

    Hi guys,

    Im currently about to put a 4 minute movie teaser on vimeo, and i am using the youtube settings in compressor. Im just wondering what the best value for the kb/s would be? Im want to have flawless quality and In the vimeo guidlines it says 7182kb/s or something ,but to me that is far less quality. If anyone has any experience in this are could you please help me out . Thank heaps!

    4 minutes I would go with the highest quality you've got, they're going to recompress. I believe I have uploaded ProRes 422 up to Vimeo.

    Yeah, pretty much, that's what I'm saying. Give it a go.

    So Vimeo will take a pro res update, and transcode from that?

    Sweet.

    Oops, no sorry, I just tried that again and it comes up invalid file. You need to go H.264 but I'd keep the data rate at 5,000 kbps or so, as long as it's under the 500 MB limit.

    I usually go 'send to' compressor, then add the youtube settings and tweak the kbps to 9000. This is much larger that your reccomended 5,000 kbps, what will this differencd have on the quality of the clip?

    It's a four minute web video... you could've done a bucket load of tests by now. Seriously, two days over this?

    Yeah and there has been numerous tests done. And I'm seeking professional advice, and searching for an industry standard or way of perfecting quality for something that means a lot to me. And as for the 'two days'...first I was told I could upload it at prores, then at 5000kbps which is half the quality I normally put it at.

    The ProRes thing was my bad and I prefaced with "I believe..." That took me 5 minutes to confirm. If you go by what Vimeo says, even double the bit rate you're still only going to get the bit rate they recompress to. Here's an example I did years ago but recently tried a re-up on Vimeo because the 1st attempt with them was seriously awful (it was a lot worse on YouTube.) The trick here was working with really fine details of a fractal image with a color gradient rotating on top. The Vimeo compression is about 1/10 the size of the original file and about 1/3 the size of the same animation on my website.

    Anyway, the whole thing about compression is you need to experiment and learn from that what works best. If it's going up on the web and especially if it's going to get stepped on by Vimeo, YouTube or someone else, take a short piece of your work--preferably a portion with lots of motion--and do a few encodes at various bitrates, upload and judge for yourself. When it comes to CODECs, bitrates and the web there really are no "industry standards."
