You embed Clevercast player on your website(s). The player on your site will automatically show all available languages through a dropdown menu (headphone button). Viewers use it to select their preferred language.

Yes. Clevercast automatically transcodes your incoming broadcasts into multiple resolutions for adaptive streaming, including HD. Languages can be selected in the same way on iOS and Android devices.

Clevercast T@H doesn’t impose a limit.

Since we use global CDNs (Akamai, Amazon CloudFront, Fastly) to deliver the live stream close to your viewers, any number of concurrent viewers is possible.

Yes. You can create white- and blacklists for countries, domains and IP addresses.

Yes, simulcasting the video with a single language (eg YouTube, Facebook) is currently available as an optional feature. Price depends on your set up, contact us for more info.

Yes, if recording is enabled for your account. The live stream can be recorded as a single mp4 file containing all audio (= languages) and video (= resolutions) streams. You can download it afterwards from Clevercast.

Yes, if this is enabled for your account. Clevercast can let you trim your recording and publish the result to an on-demand video item. Clevercast player can also be embedded on your site for Video On-Demand. Language selection will work in the same way as the live stream.

Yes, if pseudo-live streaming is enabled for your account.

Yes. Clevercast player can be branded as desired. You can also use our player API.

Yes, we have both realtime and post-event statistics like number of viewers, concurrent viewers over time, location of viewers, used devices, referrers… But there are no per-language statistics.

Yes, you can use our Webinar solution if you don’t want to host the video on your own site. In that case, you can limit the number of viewers by requiring them to register or by inviting them.

Clevercast provides a backup URL for a redundant broadcast. If the main live stream becomes unavailable, Clevercast player automatically switches to the backup stream. However, your translators will also have to switch to the backup language rooms.

They must be able to send the audio stream to Clevercast without much distortion or packet loss. This can roughly be translated into the following requirements:

• A bandwidth of at least 5 Mbps up and down.
• A wired connection to the internet! Even a good wireless connection with plenty of bandwidth may still cause audio distortion.
• A recent version of Mozilla Firefox. (Although Google Chrome also supports WebRTC, we currently don’t recommend using it.)
• A headset with noise cancelling for audio output and input, and a suited location. Too much jitter will cause volume fluctuation and glitches in the audio stream.
• No excessive packet round-trip time. If packets arrive too late, the audio will be dropped or distorted. Our ingest servers are located in Europe, so translators in Europe will mostly be fine.

For more info, see our guidelines for interpreters.

Do sufficient testing! Each interpreter should test in a situation that matches the live event as much as possible.

No. Even if it works during testing, it may still cause distorted audio during the live event.

Yes, they can translate sequentially from the same room. Translators in a language room can communicate with each other via text chat.

Yes. Clevercast allows the event manager to modify the floor audio volume in the translated audio streams. To do this, press the ‘Manage Language Rooms‘ button on the event page.

Yes, if automatic adjustment of the floor audio volume is turned on in your account settings.

Yes. If translators are in an intranet with much more traffic than during the test (eg. people viewing the live stream, multiple translators at the same location) this may cause problems (eg. dropped packets, audio distortion) that did not arise during testing.

By default, we use HTTP Live Streaming (HLS) with segments of 6 seconds. Due to player buffering this will result in a minimal latency of 18 seconds, but this may be higher on some connections and devices (with a maximum of 2 minutes on iOS devices).

We can configure your account to use smaller HLS segments, but this may cause disruptions for viewers with a slow internet connection.

Our plans are based on the number of languages, the duration of your live stream and the data traffic used by your viewers. Use our Price Calculator to calculate the cost of your Clevercast Multilingual Live Streaming plan.

If you want to use our webinar solutions, you will need a multilingual webinar plan instead.
