![]() For videos, we recommend going no higher than 10,000 Kbps, and most uploaded videos can be kept in the 5,000–8,000 Kbps range unless they include a lot of finite detail - think water, leaves, sand, etc. One of the key ways to manage file sizes on your medias is to export them with a reasonable bit rate. Uploading within the Wistia app supports file sizes of up to 8GB. On your video you’ll be able to see the current quality level under the settings menu if your video is using adaptive streaming. Keep in mind, this video is forcibly showing the adaptive streaming switch to illustrate how it would look to your viewers. The viewers don’t have to touch anything! Pretty rad, right? Check out an example of what this looks like below: If Vulcan detects a slower internet connection initially but the connection speed improves during playback, the player start on a lower quality, then switch to a higher quality stream based on this detection. However if the viewer enters fullscreen, we’ll scale up to the highest quality available if the connection can handle it. This is also informed by the size of the embedded video - if you’ve embedded a video at a small size like 640x360 wide, we won’t serve a 1920x1080 asset to that space as it’s an inefficient use of bandwidth. Wistia’s adaptive streaming will automatically choose the highest quality version of the video to serve your viewers without buffering. This means that the Wistia player will switch quality streams depending on the internet speed available, by making regular checks on the viewer’s connection. Wistia’s Vulcan player uses HTTP Live Streaming (HLS) to deliver the best possible version of your video at any given time. You can upload videos encoded with ProRes, it’ll just mean a slightly longer time to process due to the additional transcoding step. We currently have limited support for the ProRes video codec, however this will end up being transcoded to H.264 on our end. Need to transcode your video to H.264? We recommend the free tool Handbrake which we use on our end all the time. Uploading a media with an unsupported codec will often result in a media that fails to process, or a media that won’t play at all in certain browsers. The codec on a media file is responsible for compressing & decompressing the content, and it’s a crucial factor in terms successful encoding & playback. Note on Video Codecs: We currently require the H.264 codec on all video uploads, which is a common standard for web video. However, any file you upload to your account will be counted towards storage & pricing. You’re welcome to upload different file types, but we’ll only supply embed codes for videos and audio files - documents and images will only be available for downloading. Only video and audio files are embeddable. If you want 720p quality, your video must be at least 1280px wide. Here is a full list of the assets we can create, and the maximum bit rate for each: Derivativeįor example, if you want your video to play in 1080p quality, your original video must be at least 1920px wide. Each asset we create has a width threshold that must be met in order to receive that quality level, and each quality level has a maximum possible bit rate. This means that the wider your original video is, the higher quality output it will have in Wistia. The original file you upload does not get delivered via the Wistia player, we will only serve the optimized media assets we create.įor videos, we use a width-based encoding algorithm to determine the quality of assets that the video will receive. For audio files, we’ll encode a single mp3 asset. For video files, these assets will be encoded at various sizes and quality levels to ensure a great viewing experience across a wide array of devices and networks. The settings on your media are the blueprint for this process. How to Get the Best Quality Output for Your MediasĪfter you upload a media to Wistia, it enters the processing stage where we will encode a series of media assets or derivatives. Channels: 2-channel Stereo (not surround).For an audio only file, like a podcast, you will want to use an MP3 codec.Aspect Ratio: We accept videos of any aspect ratio, but wider = higher quality. ![]() Framerate: constant, 15–60 frames per second.Resolution: between 640px and 3840px wide.Wistia has a few ideal specifications we recommend when you export a media prior to uploading: Video This will make uploading easier, and you will end up with top quality web encodes for your medias!Įxport settings are configured when you publish or export a media from your editing/creation tools. Before you start uploading to your Wistia account, get familiar with our recommendations for media settings, file formats, and video resolution.
