I'm trying to figure out how I can specify a custom end time for an embedded YouTube video. I know that I can customize the start time by adding &start=30, but I haven't seen anything relating to the end time.

I need to be able to do this for a web app I'm building, so if there is no way provided by YouTube, how might I be able to accomplish this anyway?

I've skimmed over the do开发者_运维问答cumentation to no avail. Thanks!

I just found out that the following works:

https://www.youtube.com/embed/[video_id]?start=[start_at_second]&end=[end_at_second]

Note: the time must be an integer number of seconds (e.g. 119, not 1m59s).

I tried the method of @mystic11 ( https://stackoverflow.com/a/11422551/506073 ) and got redirected around. Here is a working example URL:

http://youtube.googleapis.com/v/WA8sLsM3McU?start=15&end=20&version=3

If the version=3 parameter is omitted, the video starts at the correct place but runs all the way to the end. From the documentation for the end parameter I am guessing version=3 asks for the AS3 player to be used. See:

end (supported players: AS3, HTML5)

Additional Experiments

Autoplay

Autoplay of the clipped video portion works:

http://youtube.googleapis.com/v/WA8sLsM3McU?start=15&end=20&version=3&autoplay=1

Looping

Adding looping as per the documentation unfortunately starts the second and subsequent iterations at the beginning of the video: http://youtube.googleapis.com/v/WA8sLsM3McU?start=15&end=20&version=3&loop=1&playlist=WA8sLsM3McU

To do this properly, you probably need to set enablejsapi=1 and use the javascript API.

FYI, the above video looped: http://www.infinitelooper.com/?v=WA8sLsM3McU&p=n#/15;19

Remove Branding and Related Videos

To get rid of the Youtube logo and the list of videos to click on to at the end of playing the video you want to watch, add these (&modestBranding=1&rel=0) parameters:

http://youtube.googleapis.com/v/WA8sLsM3McU?start=15&end=20&version=3&autoplay=1&modestBranding=1&rel=0

Remove the uploader info with showinfo=0:

http://youtube.googleapis.com/v/WA8sLsM3McU?start=15&end=20&version=3&autoplay=1&modestBranding=1&rel=0&showinfo=0

This eliminates the thin strip with video title, up and down thumbs, and info icon at the top of the video. The final version produced is fairly clean and doesn't have the downside of giving your viewers an exit into unproductive clicking around Youtube at the end of watching the video portion that you wanted them to see.

Use parameters(seconds) i.e. youtube.com/v/VIDEO_ID?start=4&end=117

Youtube doesn't provide any option for an end time, but there alternative sites that provide this, like Tubechop. Otherwise try writing a function that either pauses video/skips to next when your when your video has played its desired duration.

OR: using the Youtube Javascript player API, you could do something like this:

function onPlayerStateChange(evt) {
    if (evt.data == YT.PlayerState.PLAYING && !done) {
        setTimeout(stopVideo, 6000);
        done = true;
    }
}

Today I found, that the old ways are not working very well.

So I used: "Customize YouTube Start and End Time - Acetrot.com" from http://www.youtubestartend.com/

They provide a link into https://xxxx.app.goo.gl/yyyyyyyyyy e.g. https://v637g.app.goo.gl/Cs2SV9NEeoweNGGy9 Link contain forward to format like this https://www.youtube.com/embed/xyzabc123?start=17&end=21&version=3&autoplay=1

I was just trying to look up how and found there is a CLIP feature now added by Youtube right under the video that I had never noticed before!

I use this signature:

youtube.com/embed/[YOUR_VIDEO_ID]?start=[TIME_IN_SEC]&end=[TIME_IN_SEC]&autoplay=1

https://www.youtube.com/embed/2EWejmkKlxs?start=1230&end=1246&autoplay=1
