Extract text from Whiteboard recordings (NRB)
To convert NRB recordings to another format, you need NetEase Whiteboard or other Data software.
To convert other file formats to the "Session Recording File" file type, you need software like NetEase Whiteboard or a similar tool.
The .NRB file extension primarily represents an Interactive Whiteboard Recording file used by NetEase. Instead of saving heavy video streams, these files store collaborative drawing sessions, text inputs, and presentation events as structured JSON data. A secondary, older use for the .NRB extension is the Nero CD-ROM Boot Compilation file, utilized by Nero Burning ROM to save the layout and settings for creating bootable optical discs.
Opening these files requires highly specific software. NetEase whiteboard files must be loaded into the original virtual classroom or whiteboard application to visually replay the session. Nero compilation files require Nero software to burn the physical disc. Users frequently need to convert whiteboard .NRB files to standard video formats like MP4 or documents like PDF to share the session with people who do not have the proprietary software installed. However, because the whiteboard file is essentially a text script of coordinates rather than visual pixels, standard video converters completely fail to process it.
Because this is a closed, proprietary format, converting it directly into media formats is extremely difficult. Often, only the original software can properly read, render, or export the data into a widely supported format. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects the supported underlying JSON embedded format, viewing the raw data or extracting the text transcripts may still be possible. Just drag and drop your file to identify the format, view it, and convert it when possible.
Convert.Guru analyzes your NRB file, detects the exact format, and lets you read the text inside.
Users also converted UDF, NRG and IMA files.
If you want to convert NRB file to ISO, IMG, DMG, VHD, VMDK, VDI, HDD, QCOW, QCOW2, RAW, VBOX or OVA, you can use NetEase Whiteboard or similar software from the "Whiteboard Session Recording" category. In the File menu, look for Save As… or Export….
To convert VFD, DMG, OVA, IMA, VBOX, ADF, PVS, VHD, OVF, ISO, DSK or IMG files to NRB, try NetEase Whiteboard or another comparable tool in the "Whiteboard Session Recording" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NRB converter.
