Encoding profile presets

Panda provides several encoding profile presets which make it easy to setup the correct output formats for your videos.

To manage your profiles, log into your Panda account, select your cloud and click on “profiles” (assuming that you already have a cloud).

If you click Add profile you’ll be able to select from one of the handy presets. Each has a recommended width and height, but these can be changed if desired. One you’ve saved a new profile, videos you upload will automatically be encoded using it.

Available presets

Below you’ll find details about the presets available:

MP4 (H.264)

H.264 video with AAC audio for playback on HTML5 browsers, desktop players, Flash, iPhone (3GS and above) and iPad. Use H264 baseline to support most of phones like first iPhone’s and Blackberry’s.

WebM (VP8)

VP8 video with Ogg Vorbis audio for playback in HTML5 compatible browsers.

OGG (Theora)

Theora video with Ogg Vorbis audio for playback in HTML5 compatible browsers.

iPhone & iPad Adaptive Stream (multi-bitrate)

Special multi-bitrate segmented video for streaming to Apple devices. Streams of 5 varying qualities are encoded and the most appropriate quality is automatically served to users. H.264 video with AAC audio.

This profile uses an adaptive technique, and the iPhone/iPad streams one version or the other depending on the quality of the phone signal. All sub-profiles are always generated, and their specs have been set to the shown values by Apple.

Create a profile from a preset using the API

Panda gives you complete control of presets using the API and the available libraries. For this, simply pass the preset_name attribute instead of the command attribute.

In ruby it would look like this

Panda::Profile.create!({
  :preset_name => "h264", // A valid preset name, as per the tables above
  :name => "my-h264", // Unique name for this profile
  :width => "480",
  :height => "320"
})

Add Watermarking

You may want to add watermarking to your encodings. Use the api to set the url and the position of a remote image to use as a watermark.

Panda::Profile.create!({
  :name => "h264",
  :preset_name => "h264",
  :width => 480,
  :height => 320,
  :watermark_url => "http://www.pandastream.com/images/panda_logo.png",
  :watermark_bottom => 5,
  :watermark_right => 5
})
