html5 video size and compression advice required.

Recommended Posts


Hello DMS2'ers, hope you are well.


I have done a search on the forums but cannot find a quick guide to the best practise approach to html5 video as a background.


Can you use it as a fullscreen background ("set to height of window") and if so, what size must the video be to start off with?

The biggest question i have is the compression and size - would really appreciate it if someone who has done these can give me a bit of info.


I see this under more info on the DMS page editor so that is a starting point and i assume that the file must be an mpg and an ogv?

So you put one in the video format 1 and the other in video format 2.

Different browsers have different ways of handling html5 videos.
At the time of testing the best way to get cross browser support is to use an mp4 AND an ogv file.
mp4 = MPEG 4 files with H264 video codec and AAC audio
ogv = Ogg files with Theora video codec and Vorbis audio




Thanks, have a great day!

Not really a video expert, but far as I know in terms of compression, you will want to use the Handbrake app - http://handbrake.fr/

In terms of file size, this is just something you're going to have to play around with as you don't want something that is huge due to load times. The following links should help you.

      I have a map here http://www.iloveoffset.com/maps/
      I want to add several pointer locations to the map, but when I do they do not appear.
      On this map there are 2 pointer locations and as you can there is only one visible.
      Earlier today I added 7 and could only see 4 so there is something odd going on.
      My theme is up to date

      I've deleted my custom css and removed plugins. Im down to having only the following plugins:
      Contact Form 7
      DMS Professional Tools
      Pagelines Updater
      It was working fine before i have no idea what's going on with it.

      My DMS 2 site http://www.heart-stone.com/ will not save any new custom css... I can still edit templates and publish those but any custom css that I enter never saves.
      All WP files, themes, and plugins are up to date. 
      Any thought about what might be causing this?

      Is there a way to edit the custom CSS via FTP? I know I can edit the custom code in the Chrome editor but is there a file path I can use to find and edit the CSS directly from our FTP?
      Thanks in advance for the help!
