the duration is misreported at you tube, but if you download the video and check with mediainfo, the duration is correct. That is why it plays normally.

Here is a video I just uploaded where you can apreciate the quality a little better. I think I used a bitrate of 800kbps.

By the way, thanks 45tripp for the fps change command.

I have a new question. Basically does the speed of your internet affect whether a video with 800Kbit would lag? Because I can play a 1000 Kbit video with ease and yet others are saying it freezes aka the netdownload is too much. So I assume then that they need a fast speed to play the vids with no pauses?

yes a 1000kbit bitrate video wouldnt freeze because to freeze it needs to move a litlle first  here it just loadsssssssssssss

I know,
it just happens to be immaterial

of course!
once the stream has loaded (pause and wait for it), there are no lags

Heh that isn't what I meant sorry. From the feedback I have got even on a full load people have said it freezes at the same point each time. As if their GFX card wasn't good enough or something...Perhaps that is it?
I mean I get the same effect playing a 2 gig 640x480 vid on VLC Player so I assume these people are playing the 1000Kbit on a low end PC...
Am I right?

You are right. Iam from Chile, and many of my friends computers arent very good... mostly somo 4 year P4 with 256mb of RAM and no video card.
Connection speed doesnt mean anything once the video is loaded.

So then your 600 Kbit vids have lagged for them? Maybe not continuous but at certain points the video just stops...I assume?

the video doesnt play after its loaded, it is streamed, played back as it is loaded.
internet connection does matter!

Alright someone professional here tell me straight. What defines whether a video will pause for some and not for others? The higher the Bitrate...The more it happens so is it internet speed or the power of your PC?
It's strange because I keep saying I can play a 1000 Kbit fine with no lag or pauses. But then others complain...This seems to happen outside of where I live as all my friends (UK) say it plays fine...Does that have any relevance?

the internet speed no doubt, no need to get "professional help"., i lived in the uk for 7 years and the adsl penetration in the country is very high, you got all those cable companies, the country cable structure was very well planned mate.
example:
http://www.cable.co.uk/compare/regions/broadband-providers.html?s ... &y=0&=Find
take a look at the speeds and the companies, not every country got that
if people have a very slow pc chance is it wont be able to handle a fast net connection to begin with....

Thank you that was very clear and precise. I think I have everything I need to know now. Until next time.

Guiboche had problems due to using the uploader mentioned in the thread.
I've edited the guide to reflect this.

Youtube has been updated, and with the update, the resolutions have increased too. Now the encoding should use de 480x360 resolution.

However, there are now three native resolutions used by YouTube
448 x 336 for the old format pages
480 x 360 for the new Beta YouTube pages
424 x 318 is the default embedded resolution in the HTML it offers |
As you can see by the new design layaout of youtube, the beta has gone official. Besides that, Some videos I uploaded 5 days ago, with the 448x336 resolution matched perfectly to the player's screen, now they have a black space when I press the "original resolution" button. Check it if you want to: http://youtube.com/watch?v=vf2MjxPXr8Y
The embedded resolution its the same, by the way.

Yo Revan89,
I just downloaded your youtube video - www.youtube.com/watch?v=xwgVADWeNkw
How the heck did you get a bitrate of 760+?
Did you do any "hex" edits or is this the new youtube that accepts 480x360?
Also, I noted that online youtube indicates a duration of 10 minutes when the actual duration is 4:19 at 24 fps!
Also, just wondering if you know how to get h264 (x264) video and/or aac (mp4) audio into a flv container - I tried ffmpeg and it indicated that the flv codec did not accept aac (mp4) audio
TIA

Anybody know why YouTube is re-encoding my video?
http://www.sendspace.com/file/azpmff
That's the source file I'm using. There was no reason to hex edit anything since FPS were under 30 and the A/V bit rate was under 350 kb/s. YouTube is re-encoding it (it doesn't look too much worse than my master) and shitting on the audio (the re-sampling of my already 22 KHz sampled audio sounds god awful combined with the mono sound).
thx.flv

How did you uploaded the video to youtube??
If you used a third party program, thats yours problem. You have to upload videos thru the site for this system to work.

look to your audio. probably the wrong side of standard.
I changed audio (upped bitrate, consequentially hexed)

Of course he did.
what's changed to 480x360 is the display size

What do you mean I have the wrong side of standard?
I've been using LAME encoded MP3 stereo audio @ 22 KHz and ~48 kb/s ABR for all of my videos. I've never had a problem with any of them. I see you fixed this, but my question is why would you need to hex edit it at all? You can check out any of my other well encoded videos (I have some that are several months old--they weren't encoded in mencoder so ignore them) and you'll see they use the same specs and uploaded without an issue.

Okay I tried to remaster it with CBR audio @ 48 kb/s instead of ABR (because then it might not hit 48 kb/s on average--mine was actually around 44 kb/s).
It still didn't work when I uploaded it to YouTube. It's like something has changed with them. I've never had to hex a video that met all of YouTube's hidden requirements in the past. Why do you suppose this is happening?
I also fixed the AR ratio of the video. I had it mis-set at 2:1 when it should have been 2.35:1 (an error in anamorphic encoding on my part).

Encoding the video with Mencoder. I have "mencoder.exe" in my "C:" drive. Then I put the video I want to convert in my C: drive and I applied this code in Command Line (Start->All Programs->Accesories->Command Line) with subtle changes, depending on the video. (You have to put the name of your video in the code line)
| Code: |
| "C:\mencoder.exe" "C:\myvideo.avi" -o "c:\converted_video.flv" -af resample=44100:0:0 -sws 9 -vf scale=480:-3,expand=480:360 -of lavf -ovc lavc -lavcopts vcodec=flv:vbitrate=600:trell:v4mv:mv0:mbd=2:cbp:aic:cmp=3:subcmp=3 -oac mp3lame -lameopts abr:br=64:mode=3 |
Where its says "vbitrate", the number next to it is where you can asign the bitrate of your videos.

The only hex edits that I used were to change the video's duration. The 480x360 resolution can be achieved just by evading youtube's encoder. As simple as that. So, use the Hex Edit trick to change the duration of the video, as it is explained in this tutorial, and create an .flv file with an apparent bitrate of 350kbps or less.
Thats all.
