Repeat All or Part of a Video
We
all have that one song that we just can't hear enough of. If you need
to playback a video automatically, you can add the word "
repeater"
after "youtube" in the URL to open it in an external site that will
play it back as often as you let it. You can also set it to play back
just part of the video. So:
youtube.com/watch?v=kfVsfOSbJY0
Becomes
youtuberepeater.com/watch?v=kfVsfOSbJY0
Download Any Video
As
any video production student knows, there are plenty of reasons to
download a video that don't involve copyright infringement for fun and
profit. If you want to get a local copy of a YouTube video,
pwnyoutube.com can help. Just add "pwn" to the URL before "youtube" and
you'll be taken to an external site with multiple options for download
formats. With this, the following URL:
youtube.com/watch?v=Sagg08DrO5U
Would now be:
pwnyoutube.com/watch?v=Sagg08DrO5U
Bypass Regional Restrictions
Licensing
for videos is complicated enough already. If you're looking to get to a
video that has some form of restriction on it, change the format of the
video link from this:
watch?v=IEIWdEDFlQY
To this:
/v/IEIWdEDFlQY
The downside is the video will play filling the entire window. The upside is it will play.
Jump to a Specific Time
If
you need to point someone to a certain portion of a video, you can
always right click on the player and select "Copy video URL at current
time." However, if you need to be especially specific, you can modify
the end variable that follows "t=X" where X is the number of seconds
into the video that you want the player to start at. So the good part
isn't here:
youtube.com/watch?v=9R6Ibz31DtE
It's here:
youtube.com/watch?v=9R6Ibz31DtE#t=114
Disable Related Videos
It
doesn't happen often, but sometimes the related videos that are shown
at the end of a video can be unsavory. Or, perhaps you just find them
irritating. If you want to disable the array of options that show up
when the clip's done playing, add "?rel=0" to the end of the URL in the
embed code. Changing this part:
src="//www.youtube.com/embed/T0-2lzA7_Cg"
To look like this:
src="//www.youtube.com/embed/T0-2lzA7_Cg?rel=0"
Note that this doesn't seem to work on regular links. Just embed codes.
Skip to the Good Parts With the Wadsworth Constant
Just
how much of your time on YouTube is wasted watching the boring parts of
a video while waiting for the main event to begin? If you believe
Wadsworth, the answer is about 30%. While it started as a joke, Google
took it seriously enough to add the feature to YouTube itself. If you
want to skip the unimportant intros, just add "&wadsworth=1" to the
end of the URL. This will waste your time:
youtube.com/watch?v=c0KYU2j0TM4
But this is where the fun begins:
youtube.com/watch?v=c0KYU2j0TM4&wadsworth=1
Of
course, keep in mind with many of these tricks, things can sometimes
change. Most of these aren't official Google features, so they could
disappear of function differently over time. In general, though, there
are always ways to accomplish nearly everything on this list, whether
it's through Google or third-party services.
