Here are some parameters that you can be added to your Youtube video embed code to control what your visitors see.
- Â View in high quality
Youtube gives you the option to switch to high quality videos for some of the videos. Â To check if a video is available in high quality:
append ‘&fmt=18′(stereo, 480 x 270 resolution)
or
‘&fmt=22′(stereo, 1280 x 720 resolution) for even higher quality - Embed Higher Quality Videos
The above trick works for playback. Â To embed high quality videos:
append “&ap=%2526fmt%3D18″
and
“&ap=%2526fmt%3D22″
to the embed url - Cut the chase and link to the interesting part
Linking to a video where the real action starts at 3 minutes 22 seconds, wondered if you could make it start at 03:22? You are in luck.
All you have to do is add #t=03m22s (#t=XXmYYs for XX mins and YY seconds) to the end of the URL. - Hide the search box

The search box appears when you hover over an embedded video. To hide the search box add ‘&showsearch=0′ to the embed url. - Embed only a part of Video

append ‘&start=30′ to skip first 30s of the video
where any number can be substituted for 30\ - Autoplay an embedded video
add ‘&autoplay=1′ to the url part of the embed code - Loop an embedded video
Append ‘&loop=1′ to make the video start again automatically after reaches the end. - Disable Related Videos
Remove other people’s content:
add ‘&rel=0′ to the end of the url part of the embed code - Bypass Youtube Regional Filtering
Some videos are only available in certain parts of the world. Your IP Address is used to determine your location and then allow or deny access to the video. Change the url from http://www.youtube.com/watch?v=<somecode> to http://www.youtube.com/v/<somecode> - Download Video
Although not inherently a youtube trick but useful all the same for downloading videos. Just change youtube to kickyoutube in the url of the video and it will take you to kickyoutube.com with all the options for downloading the video you were watching.
