We look at a selection of embed scripts to allow you to place video, audio and other content into your website... But importantly the below examples are all responsive versions of embed scripts which are not always the 'default'. In addition to the scripts, there are often customisation parameters which can be used to edit various aspects of the player. Such as colours, widths, playback features such as 'Autoplay', API calls, background colours etc... Below we look at some popular embed scripts and review some of the available parameters available to use.

The main available parameters that can be tweaked in the URL are as follows... There are many others which relate to API calls which I have not included in the list below. Please visit YouTube to view all the available parameters.

autoplay This parameter specifies whether the initial video will automatically start to play when the player loads. Supported values are 1 or 0.
cc_lang_pref This parameter specifies the default language that the player will use to display captions. Set the parameter's value to an ISO 639-1 two-letter language code
cc_load_policy Setting the parameter's value to 1 causes closed captions to be shown by default, even if the user has turned captions off.
color
This parameter specifies the colour that will be used in the player's video progress bar to highlight the amount of the video that the viewer has already seen. Valid parameter values are red and white. Colour should be written in American English!
controls This parameter indicates whether the video player controls are displayed. 1 or 0.
end This parameter specifies the time, measured in seconds from the start of the video, when the player should stop playing the video. The parameter value is a positive integer.
loop In the case of a single video player, a setting of 1 causes the player to play the initial video again and again.
modestbranding This parameter lets you use a YouTube player that does not show a YouTube logo. Set the parameter value to 1 to prevent the YouTube logo from displaying in the control bar. Note that a small YouTube text label will still display in the upper-right corner of a paused video when the user's mouse pointer hovers over the player.
rel If the rel parameter is set to 0, related videos will come from the same channel as the video that was just played. But it is no longer possible to disable related videos any longer!

Key parameters for Vimeo... Please note that some features below are only suitable for Pro members, and if you are adding multiple parameters to the same embed code, you’ll need to separate them with ampersands (&).

autopause 1 or 0 - The Vimeo player is designed to play only one Vimeo video at a time. Suitable for pages with more than one video on the same page!
autoplay 1 or 0 - Automatically start playback of the video.
background 1 or 0 - If one, this makes the video auto-play and loop if it was being used as a cover image on a website background
byline 1 or 0 - Show the author of the video.
color (Hex Code) - Specify the color of the video controls. (Pro Only)
contorls 1 or 0 - This parameter will hide all elements in the player (play bar, sharing buttons, etc) for a chromeless experience. (Pro Only)
dnt 1 or 0 - 'Do Not Track' - This will block the player from tracking any session data, including all cookies and stats.

loop 1 or 0 - Play the video again when it reaches the end, infinitely.
muted 1 or 0 - Set video to mute on load. Viewers can still adjust the volume preferences in the player.

portrait 1 or 0 (default) - Show the author's profile image (portrait)
quality By default, the Vimeo player is set to "Auto" mode, which means it chooses the highest video quality possible, depending on the viewer's bandwidth and other factors in the playback environment. See Vimeo website for more info.
speed Show speed controls in the preference menu of the player and enable playback rate API.
#t (#t=1m2s) Used to automatically begin playback at a specific point in time. 10 seconds would be: #t=10s, 3 mins, 15 seconds would be: #t=3m15s
