Before you start uploading to your Wistia account, get familiar with our recommendations for video resolution, settings, and formats. This will make uploading a painless experience, and you will end up with top quality web encodes for your videos!
Wistia does have a few specifications and guidelines we recommend following in order to obtain the best performance using our service.
- Codec: h.264
- Resolution: between 640px and 3840px (4K) wide
- Bitrate: 5,000 – 10,000 kbps
- Framerate: constant, 15-60 frames per second
- Aspect Ratio: Wistia accepts videos of any aspect ratio.
- Codec: AAC (Advanced Audio Codec)
- Sample Rate: 44.1 kHz
- Channels: 2-channel Stereo (not surround)
And now, a little more explanation on why these settings are preferable:
After you upload a video, we perform encoding on it – creating multiple derivatives for different use cases and environments (like mobile devices and Flash) and we also get these versions ready to play on the web. We have video type detection and encoding settings (what we call Smart Encoding) so that live-action videos look great, and longer videos that require fine detail (like Webinars) will be as efficient a file-size as possible (for smooth playback).
The largest resolution we create is 4K, or 3840px by 2160px. We’ll create derivatives based on the width of the original file. If you upload a 4K video with a 16:9 aspect ratio (the most common here) we’re going to create the following derivatives (as well as some Flash counterparts):
|3840p x 2160p||7,500 kbps|
|1080 x 1920p||3,750 kbps|
|720 x 1280p||2,500 kbps|
|540 x 960p||1,200 kbps|
|360 x 640p||700 kbps|
|224 x 400p||200 kbps|
