Ever wanted to direct someone to segment in the middle of a video without having to write begins at 3:04? Well now you can by using splicd.com. Grab the link to your YouTube video, input the start and end time, and when the link is played, it will automatically jump and start to play at the selected queue. Pretty handy if you want to pick out that :30 sound-bite from a 1/2 hour show.
Example: Craig Ferguson Press play, and it will jump to the 2:52 to 3:01 segment. Doesn't always stop at end of segment, though. Hey, what do ya' want for free? lol.
