Getting a embedded YouTube Video to Autoplay and Loop - StackOverflow
YouTube Player Parameters — Google
I've used this trick on a few of my Instructables, including:
Hamster Wheel Standing Desk and AlphaClamps
Step 1: Remove the Audio from your video
Unless you want to annoy the bejesus out of your audience, make sure your auto-start looping video is silent.
I use Premier Pro (Right click the sequence, Unlink Audio, Delete Audio, Export)
This takes forever and Premier is expensive and has a helluva learning curve.
Quicktime Pro 7 can do it, and is cheap.
Window Movie Maker can do it according to YouTube, but I don't have a PC.
Step 2: Go to your video, get embed code
After uploading your silent video to YouTube, go to the URL and click the share button. Then click the Embed button.
The width of an instructable is about 600px. Click Custom Size, type 600 in the first box and let it fill in the second box. This saves you some math.
Every YouTube video has an ID. In the case of the video above, it is j7FioTdZaEk. They are case-sensitive. In order to make your video loop, you must add a playlist flag pointing to your video's ID. I don't understand why, but it is important.
Uncheck all of the boxes, noting how the code changes. The text being appended to the "src" url are known as flags. & or "&" are used to separate flags. Flags can be put in any order, so long as there aren't any spaces. Some of the flags can be added with the checkboxes, others have to be typed by you. the =0 means off, while =1 means on.
