Чем открыть файл в формате ARF
Формат ARF относится к категории файлов “Cisco WebEx Advanced Recording File”. Cisco уже давно считается одним из лидеров в области оказания услуг по поиску сетевых решений и смежных технологий для коммерческих структур. Cisco WebEx – дополнительный сервис, специализирующийся на организации и управлении онлайн-семинарами, презентациями и различного рода конференциями. В основе формата ARF лежит тип Network-Based Recording, NBR (запись по сети). Как частный случай NBR, ARF расширение широко применяется для записи онлайн-трансляций посредствам веб-оборудования.
Непосредственно сам ARF файл содержит в своей структуре поток аудио/видео контента в цифровом исполнении. Инновационный алгоритм сжатия, применяемый для пакетирования формата, способствует качественной записи и хранению в одном архиве самых разнообразных типов данных, включая media/video дорожки, текстовую информацию в виде аннотаций, прикрепленные файлы и.т.д. Таким образом, ARF формат представляет собой автономный мультимедийный файл.
Программы для открытия ARF файлов
Для открытия и воспроизведения ARF расширения на базе платформы ОС Windows необходимы специальные приложения, в частности:
Формат ARF также адаптирован для других ОС, например, в Mac ОС расширение может быть открыто с помощью плагина Cisco WebEx Network Recording Player.
Если при попытке загрузить расширение ОС выдает ошибку: производится открытие ARF файла с использованием некорректного приложения.
Конвертация ARF в другие форматы
Поскольку практическая область применения формата ARF не столь широка, трансляция его в другие расширения бывает востребована крайне редко. Однако, если в этом есть необходимость, для организации процесса конвертации можно воспользоваться теми же программными утилитами, что и для воспроизведения, например, XnView или NBR Player Execute Module.
Свою помощь в конвертации видео-форматов вам также может предложить один из многочисленных онлайн-сервисов: Movavi.
Самые популярные для преобразования расширения – традиционные AVI и MP4.
Почему именно ARF и в чем его достоинства?
Благодаря прогрессивному алгоритму пакетирования, применяемому для генерации ARF расширения, оно является одним из самых востребованных форматов для записи и хранения различных онлайн-трансляций.
Запись онлайн-встречи, загруженная с WebEx. Записывается при помощи Network-Based Recording (NBR). Содержит видео-данные, таблицу с содержимым, список участников и другую информацию на отдельных панелях.

What tools does WebEx provide for recording, editing, and playing recordings?
With the WebEx recorders you can record everything that happens in a WebEx meeting; audio, video, chat conversations, notes, etc.
There are two options for recording a WebEx meeting: Network-based recording (Record on Server) with the Network-Based Recorder (NBR) and Local recording. When using Network-based recording, no additional hardware is required. All meeting content is automatically recorded on the WebEx servers and is easily accessible.
If you want to change the recording, such as making it shorter or eliminating sections where nothing important is happening, we provide another tool that allows you to change it. If you save recordings to your WebEx service site, you can publish the recording on a Web page so that others can play it or download it to their computer.
Choose from the following players and recorders:
WebEx Network Recording Player for Advanced Recording Format (.arf) files
Use it to play recordings in ARF format (Network-based recordings). Use the player to convert recording to Windows Media Format (.wmv), Flash format (.swf), or MPEG-4 format (MP4). No editing is supported in the player. Basic editing is supported on the recording properties on your WebEx service Web site, such as truncating the beginning or end of the recording, and removing panels such as video, chat, etc.
WebEx Recorder and Player for Recording Format (.wrf) files
This is a standalone recorder and player that allows you to save recordings in the WebEx proprietary WRF format on your computer. You can also use it to record applications or your computer to create software demonstrations, training, and so on. You can then upload recordings to your WebEx site and share them with others by sending them the provided streaming/download URLs.
WebEx Recording Editor
Use this tool to add, delete, or rearrange parts of a recording in WRF format.
For detailed information about using each of these players, see the user guides on the Support page of your WebEx service site.
What do I need to play recordings?
To play WebEx recordings you should have a sound card; to play recordings on the Web you should have an Internet connection.

Network-Based Recording or “Record on Server”
What is network-based recording (NBR) or «Record on Server»?
Network-based recording (NBR) is a recording option available to WebEx customers on release WBS25 or later. Network-based recording enables you to capture all meeting content, including WebEx integrated audio, VoIP audio, or third-party audio conference for later playback and sharing. NBR recordings are saved to WebEx high-availability storage servers, making it easy to access all meeting content.
Unlike the stand-alone WebEx Recorder for WRF format files, network-based recording is managed completely within the WebEx client and does not require the use of additional hardware, such as a phone recording adapter to record the teleconference. Network-based recording also provides basic editing capabilities through your WebEx service site, without requiring the use a video-editing application.
Which centers can use network-based recording?
WebEx Meeting Center, Event Center, Support Center, and Training Center.

I cannot play my network-based recording file on the latest WebEx Network Recording Player after my site was upgraded. What should I do?
Starting in WBS28.9, a new audio engine was introduced in the WebEx Network Recording Player, and an old audio codec was removed. Due to those changes, network-based recording files (.arf) that were created on a release earlier than WBS27.12 (earlier than March 2010) and use VoIP-only audio can no longer be played on the latest Network Recording Player (they can still be played on earlier versions of the WebEx Network Recording Player). Network-based recordings that use VoIP-only audio and that were created after WBS27.12 can be played on the latest release using the new player with no issues. Network-based recordings that use hybrid audio (mix of VoIP and telephony or telephony only) are not impacted. If you still have access to an older version of the Network Recording Player, you can convert your recording file (.arf) to standard video format such as Windows Media File (.wmv) format, Flash (.swf) format, or MPEG-4 format (MP4).
Note
The WebEx Network Recording Player does not support converting recordings to MP4 format on Mac systems.
Playing Recordings
