Converting YouTube flv to mp4

Posted 2010-10-23 (土) 午後11:21 by terra

Note: The following was originally posted on twitter because I play around with video files a lot and I thought I’d answer some questions that people sometimes ask me.

Some of you might wonder about what I do when I say I losslessly remux FLV files from YouTube to mp4. Here’s an overview:

If you’re slightly familiar with YouTube formats, you’ll realise that YouTube uploads files in a combination of FLV and MP4. All HD formats (720p and above) are mp4s; all non-HD formats are in FLV/3GP (with the exception of 360p which comes in both mp4 and flv).

FLV and mp4s are essentially container formats (i.e. they contain video/audio streams that are encoded using certain codes).

For YouTube, all videos, no matter whether they are FLV or mp4, contain H264 MPEG-4 AVC video streams; audio are AAC streams.

So technically, all YouTube videos can be converted from FLV format to mp4 format without loss in quality.

Twitter as a form of mass protest

And no I’m not talking about the Iran election.

I’m on vacation today. Woke up early and visited my newest internet guilty pleasure ONTD_Ai because it’s just too fking enjoyable to pass. (Not to mention I’ve been in a bit of a depression the last couple of days and needed an avenue to vent.)

I found myself embroiled in the start of a whole controversy pertaning to homophobia related to a certain “scream on” reality person’s family over a private dinner comprising the cast of our favourite TV show.

Gadget want list

The economy is in a tailspin and there is a slump in demand for discretionary goods, but you can’t stop even a poor (jobless) geek girl from making up her gadget wish list can you?

First blog post on this site using the Asus EEEPC 900HA

Blogging from my latest toy, the Asus EEE PC 900HA. Finally got my hands on it after half a week of painful waiting. But it’s all worth it cos I managed to get it in time for my birthday :)

Had a great birthday dinner today. Thanks to all the friends who came and celebrated with me.
