What's new: more bug fixes for the blank download page. More in the changelog.
The script works in:
- Firefox (install Greasemonkey or Scriptish first)
- Google Chrome (use the Tampermonkey extension. Chrome has built-in support for user scripts, but starting with Chrome 21, it's more complicated to add them: you need to download the script, open its folder and drag the file to Chrome's extensions page - chrome://extensions/.)
- Safari (install the NinjaKit extension first. Make sure that extensions are enabled in the settings, download the file and double click it. Then you can install the script. More information here.)
- Internet Explorer (install IE7Pro, download the script, change the extension to .ieuser.js, copy the file to c:\program files\iepro\userscript and enable the script in IE7Pro's settings dialog. When you install IE7Pro, make sure to disable bundled software.)
- MP4 360p (384x288, 480x360, 640x360) - all videos are available in this format. Use it if you want to play videos on a mobile phone (iPhone, Android) or to save space.
- MP4 720p (1280x720) - HD format, available for an increasing number of videos. Use this format if you want to play videos on a tablet (iPad, Motorola Xoom, Samsung Galaxy Tab) or a laptop.
- MP4 1080p (1920x1080) - Full HD format, available for less videos than MP4 720p. Use this format to watch videos on a HD TV or a high resolution monitor.
- MP4 4K (up to 4096p) - HD format, available for a few videos.
- the highest-quality FLV version available: FLV 360p (480x360, 640x360) or FLV 480p (640x480, 854x480). Even if they have a different extension, .flv videos use the H.264 codec, just like .mp4 videos.
- VLC (Windows, Mac, Linux / plays both MP4 and FLV videos) - recommended video player
- Windows Media Player 12 for Windows 7 (plays only MP4 videos)
- iTunes and QuickTime Player (Windows, Mac / play only MP4 videos)
- video players for mobile devices (for example, MP4 360p videos are better suited for older smartphones like iPhone 3GS, HTC Desire, Galaxy S/S2; MP4 720p videos are great for more recent smartphones (iPhone 4/4S/5, Galaxy S3), 7-inch tablets and older 10-inch tablets (iPad 1/2), while 1080p videos work better on the latest iPad, Nexus 10 and other high-resolution tablets and smartphones.)
