YouTube team just announced on their official blog the brand new Multi-Video Upload system that allowed you to upload up to 10 minutes in length and 1 GB in size. This new file size limit only for the new Multi-Video Upload, single video upload still limited to old file size limit; 100MB.
I just tried to en-queue a total of 45 videos in the list and I got no complain from this system, so I jump to conclusion that this new Multi-Video can upload unlimited or very large number of videos simultaneously.
The coolest thing about this new YouTube multi-video upload system is, it use AJAX technology extensively. When you add a new video to the list, the new video will be automatically added to bottom of the list and the list itself will stretch accordingly; no more page whole page load, that just very convenient. The same goes when you want to add video title, description or keyword just click on the text as image above and it will turn into editbox!
The edit options link above used if you want to add more video options such as video category, broadcast options, date and map options and sharing options.
Aside from the cool thing there is also downside IMHO, for me I would prefer stand alone win32 program rather than web base application because a lot of thing can happen with browser; browser crash or hang and all your hard work just gone like that. Different with stand alone application which you have more control over the situation, not to mention a lot of better feature can be implement surpass the limitation of web application.
Anyway, if you decide to use the multi-video upload feature, just go to the installer webpage to install the plugin.
