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.

An unlimited number.

Since we use Amazon CloudFront for worldwide delivery, the number of concurrent viewers is more or less unlimited. If you expect 10.000 concurrent viewers or more, we’d appreciate a heads up.

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

Yes, this 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. Clevercast player can be branded as desired. We don’t require our logo or watermark. Even the player’s colors can be customized 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.

Our pricing is based on the number of languages, the duration of your live stream and the traffic used by your viewers.

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.

Currently not (but we’re working on it). If the floor language constantly changes, you shouldn’t use Clevercast T@H. If the floor language is mostly the same with a few exceptions, you can use our workaround with the ‘Original’ language.

Set the ‘Original’ language as the default language. If you only have two languages, you can set the ‘Translation’ language as second. Otherwise add the actual languages as additional languages. Viewers will notice that they only need to switch to ‘their’ language when the presenter is not speaking their language. Otherwise they can listen to the Original language.

Clevercast allows viewers to hear a faded version of the original audio in the background of the translated audio streams. But this background volume must be set before the event starts and can not be changed during the live stream.

You can set the background volume level via the Account -> Settings menu: go to the ‘Languages’ panel and update the setting ‘Background volume of the original language in a translated audio stream, on a scale from 0 (no background volume) to 99 (very loud)’.

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.
