Video encoding settings for Wiredrive

Use the following settings to encode files for playback in all major browsers and Apple iOS devices.

Format
QuickTime movie (.mov)
Wiredrive uses the QuickTime plug-in for browser playback. If you encode video with Adobe Media encoder, use the level 3 baseline profile, otherwise QuickTime files won’t play in WordPress.
Codec
H.264 (.mov, .MP4 or .M4V)
Data rate (bit-rate)
Appx. 1750-2000 kbps
The data rate is the biggest factor in determining file quality and its capacity to stream over a range of internet connections. Files with a lot of detail and motion should be compressed at higher data rates than files with minimal motion and color. Compress files at a lower data rate if your client is on a slower internet connection.
Frame rate
Current
If your encoding software does not have current as an option, choose 30.
Audio settings
Codec: AAC;
Sample rate: 44.1;
Bit-rate: 128-320 kbps
If you are a music company, you may want to choose the larger bit rate. This will also affect the final compressed file size. Please note that while you can use the PCM + Integer (Big + Little Endian) audio codecs, these codecs are not readable by the Flash player used to display media on PCs, resulting in PC users not hearing the file’s sound. As a result, we do not recommend that you use this codec.
Aspect ratio
720×540 for 4:3 files
720×405 for 16:9 files
You can use any dimension, but Wiredrive will scale extra large files down to fit inside the viewer’s display. If you do opt for a much larger aspect ratio, you may need to adjust the data rate accordingly. Keep in mind that higher data rates do not work as well on slower networks and usually are not the best route for encoding. Do not encode files with the anamorphic setting on, as files will look stretched upon playback.
De-interlace
Yes, in most cases
Video shot for TV is usually interlaced to trim broadcast bandwidth. You should de-interlace video shot for TV to avoid scan lines and artifacts. Many modern devices use progress scan. De-interlacing progressive scan media is usually OK, but this varies by encoding software. Check your software documentation for more information.
Fast-start
Always use fast-start
If the fast-start option isn’t readily available, check your encoding software documentation for instructions on how to enable this fast-start. Otherwise, people will have to wait for your media to fully load before it begins playing.
