Use MarsEdit to Embed Sound and Video

I use MarsEdit to write my blog. My blog is hosted in Wordpress.com. I can use MarsEdit to insert photos easily in the post, but can’t do it with videos and sound files. I choose to upload sound files to SoundCloud and video files to YouTube and embed them to my blog. Here is the guide from MarsEdit:

In MarsEdit, locate the text cursor in the post where you want the video to appear, and select Edit -> Paste HTML Source. This will insert the embedding code correctly in either Rich Text or Plain Text modes.

Here is the example:

SoundCloud:

[soundcloud url=“https://api.soundcloud.com/tracks/191036218" params=“color=#ff5500&auto_play=false&hide_related=false&show_comments=true&show_user=true&show_reposts=false&show_teaser=true” width=“100%” height=“166” iframe=“true” /]

Youtube:

The embedded SoundCloud player fits the screen, but the embedded YouTube player occupy the whole width and is ugly. I need to learn how to adjust the width of the embedded player.
