Knowing how to encode video files for the web is a critical part Wiredrive, as you need to anticipate your audience and know the ideal file size to quality ratio. The following discusses recommended starting points for file encoding for the web and reviews a few key concepts in video encoding. You may also just need compression suggestions.
- Encoding Settings
- Selecting an Aspect Ratio
- Main vs. Baseline Profiles
- Sorenson Squeeze Presets
- Adobe Media Encoder Settings
Encoding Settings
Format: MPEG-4 (.mp4)
| Codec | Aspect Ratio | Data rate | Audio Settings | De-Interlace | Fast-Start | |||||
| H.264 | 540p (960x540) | 1750-2000kbps | Codec: AAC Sample Rate: 44.1 Bit-rate: 128-320 kbps |
Yes | Always | |||||
| H.264 | 720p (1280x720) | 4000-5000kbps | Codec: AAC Sample Rate: 44.1 Bit-rate: 128-320 kbps |
Yes | Always | |||||
| H.264 | 1080p (1920x1080)* | 5000-7500kbps | Codec: AAC Sample Rate: 44.1 Bit-rate: 128-320 kbps |
Yes | Always |
*Please note that in the Wiredrive admin portal anything over 1600 x 1080 will scale in Wiredrive to 1600 x 1080 based on aspect ratio so you will not get the full size in system playback.
Selecting an Aspect Ratio
You may upload your file at your desired ratio. If you are concerned with storage space. Most users will not be able to see a difference between 720p and 1080p on their computer screens, as Wiredrive is going to scale the file based on screen size and page space. 720p will also keep your file sizes smaller to save space in your Wiredrive system
Profile Levels
Wiredrive by default supports profiles between 1-4.1,280×720@68.3fps anything over that profile will be transcoded down to meet the standards for playback supported in our player.
**For mobile presentation viewing, we suggest a profile between 1 and 2.2. As we do not adjust our player for mobile playback at this time. It is best to encode files in the first two profiles if you have a large number of users on mobile viewing presentations. As we can not account for mobile device types, hardware performance, or connection speeds, it is best to adjust to profiles between the above suggestion levels
For additional information on Profile Level, please see the flowing chart.
Adobe Media Encoder
Adobe Media Encoder is a Premium encoding application you can purchase or is included with your subscription to the Adobe Creative Cloud. The screenshot below shows the settings most clients use for HD files.
Handbrake
Quick tool to encode files from external sources that may not be in the proper format for Wiredrive playback. If you do encode with Handbrake, follow the encoding settings at the top of this page but make sure that the following settings are in place:
Video Settings:
Format: MP4 File
Check Web Optimized
Encoding Options: H.264 (x264)
Framerate (FPS): Same as source
Quality: Average Bitrate (kbps): 3800 (1080p), 2800 (720p)
Enable: 2-pass encoding, Turbo first pass
Encoding Options (for more advanced users):
- Profile: Main or Baseline
- Level 4.0 or less (Otherwise we will transcode the file)
Picture Settings:
- Storage Size: Confirm dimensions are correct
- Enable: Keep Aspect Ratio
- Anamorphic: Off
- Modulus: 4
- Cropping: Confirm whether you want to crop black pillars or bars
