Here's what the comparison so far has shown;
1 - WLMM compresses the video and loses a little bit of quality, but uses a higher bitrate so makes a larger file.
2 - youtube and vimeo then compresses the video heaps more and loses a lot of quality
3 - youtube uses a higher bit rate for 1080p movies than vimeo
4 - youtube gives you 1080p for free

True, the next test would be to use raw footage for upload. But, comparing footage uploaded from WLMM is quite relevant because most people will edit their footage with something before uploading.

Youtube also has an advanced Java option that sends the file in packets and will therefore handle connection drop-outs, this might work better for you Simon. I'm pretty sure they don't delete videos with songs anymore. They match the song and automatically credit the music to the original artist with a link. They also have an audio replacer tool I think so you can swap in unlicensed music.

I think it was Ray who had one deleted just a couple of weeks ago for music infringements

I keep retrying crap tube every now and then but same old same old. This is an issue that affects poor smuchs in my predicament.

And there are very few compared to the total of YouTube uploalders. Again I dud research 5 or 6 year ago and I'm on the same rim with the same issues. The problem will go away when I move ( or the nbn is built) tried a mates connection in the same street same issue but if I up load at work no prob or away from here again no probs.

I will stick with vimeo for now.

The TRA page brings views from all over the world so may as well keep that up

ShaneO if the new stealth comes without wind rush I will agree but the go pro I better cause the audio works.

When the stealth audio works they will be the best. But not yet

Bloody hell

what was I on last night someone should hae told me to stop while I was ahead...

some of what I coukd not remember is re the video stream is the called the "container" You change this when you transcoce through wlmm or any editor. a clipping program will not change the "container"
But there are probably better experts on here than me that can expain it better.

Oh and with Vimeo

they started to run a higher Bit rate as per Craptube but had to reduce the bit rate as it was too much of a drain on the servers (Not like we have seen this before hey wes??)

This is only scuttlbut or gossip that I had passed on (and I cant find the thread any more) but it is born out by your test that you have done downloading the streams.

Another thing I would be interested in seeing is

if you were to download the same vid 3 times at three different times of day or night and see if the file sizes and atributes are the same.

also possibly doing it from work on a different computer and connection and seeing if the stream is the same.

lastly down load a sample of the HD featured vids and see if the bit rate is satble at that level that you measured.

(this might piss Vimeo Off as it would prove they have reduced their streaming Bit rate)

still its almsot half youtube but the qualty is almost equal. they maust have some decent software back there?

Lastly (well perhaps)

Why the interest Wes

you looking at a side line? get a decent uplink and start Wes's video server and charge a bit???

I've had enough of servers, no plan to start any type of video server!

Simon, the mp4 file that gets streamed on youtube and video doesn't change, it's always the same file. I'll try downloading from the HD channel, but I am sure it will be a lot bit rate too, as you said, it is to conserve bandwidth. The video info on the right is just what was uploaded, it is nothing to do with what your watching as a stream.

For great quality, other than a MAC, you can build a hackintosh or use an emulator, but it's really not worth the drama. MAC OS can run on PC components (ie: hackintosh) but for editing the PC gpx doesn't agree with FCP

Bloody Apple angry5

Pro Res 422 is matched for PC with other intermediate codecs from Avid & Cineform.

Cineform is the studio that developed the software the Cineform444 codec that GoPro uses, especially for the 3D System, they bought the studio & that's the software they give away for download to use the 3D.

Windows prefers it's files in AVI & MAC in .MOV when using cineform

The Cineform basic editor is about $300

Vimeo & You Tube handle the codecs & wrappers (AVI & .MOV) differently, so there'll be different results depending on the intermediate codec & the way it's exported.

mmmmm Mumbo Jumbo tech stuff, i just want my arm fixed so i can ride again :D

Oh yeah, You Tube still restrict some music in videos, they normally just restrict the video based on country.......VIMEO now has a music store !

Im with You Dags

Need the back Good then Get on the bike.

(oh and buy a new camera Or two...)

Also I ment to say re the class 10 cards

This issue with getting Class ten cards came about not for the helmet cams but for the hand held pic cams

when using in burst mode the biggest slow down was the card write speed. a class ten card would speed up the burst mode when taking pics on rides and you capture much more action when taking Pictures on a handheld.

I then said well if you are getting cards may as well get them to suit any camera you have.

Just thought I would mention this.

You should download jdownloader, that's what I use to grab the video files that the streaming videos are coming from.

VLC player gives me the following codec info.

This is for footage straight from the gopro camera

and this is for the gopro Hero2 video on youtube

They both use the same codec. The difference is the youtube version is a much lower bitrate, but with no real loss of quality. I guess they have a good compression program that they use post editing. Something that I assume does multiple passes. I think that's the key to looking good on youtube, compress it yourself using good software and lots of passes.

If you upload something to youtube above a certain bitrate, it obviously decided it needs to compress it further. I guess it uses software that does a single rough pass, to save on server processor power.

yeah, I don't know, there's some smoke & mirrors that goes on. The codec on download might be a bit irrelevant, Simon & I bounced a shyteload of test videos around a few years ago now & oddly enough before all the upgrades MP2 was the clearest & smoothest, mainly because H.264 was so prostituted even though it was meant to be industry standard.

GoPro is a partner with some video streamers, it would be fair to say the exact details of the way thier individual codec is handled 'may' be better than some.

the exact same codec by name or ID found in 1 brand of editor can be vastly different in another brand & the way it's streamed & also the properties will vary post export, so it's almost irrelevant.
the key is finding the right 'this goes with that' - GoPro, Woodmans labs, Cineform have that sorted well, they use processes far out of reach of any of us.

And yeah Simon, that good ole SD Card thing again, haha we've had some good chats over that BangHead

You're right about the burst & stills for sure, you only have to now see what GoPro are recommending now, gone from class 4 to class 10 with the introduction of 0.5 photo burst.
For all other uses, video etc. Most camera USB Host Readers are only capable of Class4, so there's not much advantage going higher, except of course for transfer speeds outside of the camera.
That was the official response also from GoPro about the original HERO HD as well.
But typical marketing hype left everyone feeling they had to have bigger, has worked well because now class10 genuine cards are cheaper than the class 4 in many cases.
I don't get why some resellers still have class 4 & 6 32GB (and some still sell Class2 in the Micro for that) at $129.00 & $149.00 when our genuine brand name ones in class 10 are $85.00 RRP

1 & 2 - same vid on youtube & vimeo, buggered if i can see any difference
3. I do like the way the new Contour blows away the HERO in poor light, be good to see how the HERO2 goes now that it's got the same type of lens

Using Cineform to convert RAW Footage straight off the GoPro HD you can see the changes it makes, and the size of the files too
