FastStart on .MP4 files

January 15th 2008

After many weeks trying to convince everybody to submit stuff in .MP4 to xplsv.tv as the best format, I finally faced the process of creating a .MP4 myself.

The idea was to submit a couple of my favourite demos to the site. The process is fairly simple, use kkapture for creating a bunch of uncompressed .AVI, then load them up on After Effects, which already puts them on a sequence, crop the video if needed and export as .MP4. I had to do many tests at different resolutions until I finally reached a resolution/quality I was happy with. And what was my surprise when I uploaded the first file and it didn't have fastStart!

Just so you know what I'm talking about, fastStart is how they call to progressive loading now. The idea is that you don't have to wait until the whole video is loaded, but you can see on-the-fly what has been loaded already.

Seems like After Effects, Premiere and similar tools aren't able to do that, so you need a compile this qt_faststart.c file and then use it to fix the generated .MP4, which, thanks to devcpp was just a matter of seconds.

If you don't want to mess with C compilers, here you have the compiled version for Windows: qt_faststart.exe (it's a command line app, needs to be used like this: qt_faststart.exe my_video.mp4 my_video_fs.mp4).

Anyway... here are the videos:

http://xplsv.tv/movie/2377/
http://xplsv.tv/movie/2378/
http://xplsv.tv/movie/2379/
http://xplsv.tv/movie/2380/
http://xplsv.tv/movie/2381/

Now the problem maybe is that I have done the captures with too much quality (1024x576 3500...) and people don't have enough bandwidth to watch them... But at least, I know that they're small enough so they can still be played on a G4.

EDIT: And here is the Mac version (thanks to sole).

Hello,

I'm interested in phodoob flash application. Could you send me the source code ?
I don't need documentation, i can search by myself, because i know you have not the time to explain me how it works in details.

Thanks in advance, and happy new year 08.

Hi MrDoob!

My name is Jasmina and I want to thank you for your great examples for papervision3d. I'm still a beginner, but source files you posted on your site are great. Can you please give me source files for "Hello" papervision experiment? I'm trying to make something like that and want to see how you did it.

Sorry, my english is not so good.

Best regards,

Thank you

Hi,

could you upload to your blog (or send to me) the source code for your pv3d "hello" experiment. I'm new to papervision/flash and would like to see who you did the mouse movement and reflection.

cheers,
XXX



Dear Mrdoob,
I was deeeeeeeply attracted by your xplsv.tv gallary, and have been trying to make my website like that, and you can see it here: XXX.

you see, we made it as the xplsv.tv mosaic.
Actually,
I myself know little about Flex or something, it's my friend who made this new website. I'm now working on it, although it's so hard to me.

but we still don't know how the gallary works, could you by any chance give us the source code? I'll appreciate it very much!

Regards,
XXX



And a very looong etcetera...

Supersole's Iceland EP Cover

January 6th 2008

Supersole - Iceland

Had to do a quick-1hour cover for supersole's latest ambient EP last night.

Not sure about the type used, but what I remember from Iceland was a mix of Out-of-this-world landscapes + Weird mix of designs/styles.

Happy 2008 - Fireworks effect

December 29th 2007

Probably my last effect this year :(

fireworks effect

Thanks for following my blog, and have a great 2008.
Have fun with the sources ;)

UPDATE
Some people were asking for the ColorUtils.as class, so, instead of sending the file by mail, I guess its better to update this post. But, if you want a quick challenge, try to recreate the file by yourself first.

PV3D 2.0: Real Materials

December 20th 2007

Now that we have some shading action with pv3d 2.0, I though it was time to revisit the real materials topic.

John already shown that Bump is now possible, so, testing a bit his code a I came up with something similar, but in this case I'm using Mars, and, guess what, you can change it's shape with a stupidly weird one (tho it's dynamic, yey!).



Next thing on the list was reflections. Not real time ones tho (yet), but Ralph also already shown an example with them. Here it's my version, mixing it with the previous code.



And you may well say, doh! seen it already... Fine... But, what about refraction? :D





Hehe.. it has been kind of fun... Source available from within the effect, (take a look at the top nav). But, apologies this time, there is a lot of stuff commented and unneeded stuff on them (I may clean them later).

FWA's Site of The Day!

December 17th 2007

Since the beginning I had a joke on my site (now blog) on the top right corner which was the FWA, best site ever ribbon. What I really didn't ever though is that I would be offered to add a real one at some point.

Well, what can I say? Really excited about it, and very encouraging to keep doing what I like to do.

Thanks FWA guys!
