CREC File – What is .crec file and how to open it?

Definition:

A CREC file, short for “Lync Video File,” is a video file format primarily associated with Microsoft’s Lync and Skype for Business communication platforms. These files contain video conferencing recordings, including audio, video, and any shared screen or presentation content from the conference. Lync and Skype for Business users can easily record and save video calls for future reference or sharing.

Technical Details:

CREC files are typically encoded using the H.264 video codec and the AAC audio codec. They are compressed in an MPEG-4 container format, which ensures compatibility with various media players and platforms. CREC files are typically of high quality, preserving both audio and video clarity. They may also include additional metadata, such as the participants’ names, the meeting date and time, and the conference topic. CREC files can be played back using Microsoft Lync or Skype for Business clients, as well as various third-party media players that support MPEG-4 container formats.

Opening CREC Files with Microsoft Software

CREC (Lync Video File) files are proprietary video files created by Microsoft Lync, the predecessor to Microsoft Teams. They contain recordings of audio and video conversations, including screen sharing and annotations. To open CREC files, users can employ the following Microsoft software:

• Microsoft Teams: If the user has access to Microsoft Teams, they can import CREC files into the application. To do this, open Microsoft Teams, click on the “More options” (three dots) icon, select “Settings,” and then navigate to “Recorded Calls.” Choose the “Import” option and browse to the CREC file location. The file will be converted to a playable format within Microsoft Teams.

• Microsoft Stream: Microsoft Stream is an enterprise video platform that allows users to upload, share, and view videos. CREC files can be uploaded to Microsoft Stream, where they will be automatically converted to a playable format. To upload a CREC file, log in to Microsoft Stream, click on the “Create” button, and select the “Video” option. Choose the “Upload video” option and browse to the CREC file location.

Alternative Methods for Opening CREC Files

In addition to Microsoft software, there are alternative methods for opening CREC files:

• Third-party converters: There are various third-party software tools available that can convert CREC files to more common video formats, such as MP4. These converters typically require users to purchase a license.

• Online converters: Some websites offer free online conversion services that allow users to convert CREC files to different video formats. However, these services may have limitations on file size and conversion quality.

Introduction to CREC File Format

CREC files, also known as Lync Video Files, are a proprietary video format developed by Microsoft specifically for the Lync video conferencing platform. They encapsulate both audio and video streams within a single file, making it convenient for sharing and storing recordings of Lync video calls. CREC files are typically generated when a Lync call is recorded, either manually by participants or automatically based on predefined settings.

Characteristics and Metadata

CREC files utilize the Advanced Systems Format (ASF) container format, which allows for efficient streaming and playback. The audio stream is usually encoded using the Windows Media Audio (WMA) codec, while the video stream employs the Windows Media Video (WMV) codec. Additionally, CREC files may contain metadata such as the meeting title, participants, start and end time, and any associated notes or attachments. This metadata can be useful for organizing and searching for specific recordings.
