Extract text from Adobe MPEG index files (MPGINDEX)
To convert MPGINDEX index files to another format, you need Adobe Premiere Pro or other Data software.
To convert other file formats to the "Media Cache File" file type, you need software like Adobe Premiere Pro or a similar tool.
The .mpgindex file is an Adobe MPEG Index File generated by Adobe video editing software such as Adobe Premiere Pro, Adobe After Effects, and Adobe Media Encoder. It is a system-generated cache file used to speed up the playback, scrubbing, and rendering of MPEG video files. Instead of decoding the entire video stream on the fly, the software reads the .mpgindex file to locate specific frames instantly.
Users often try to convert these files because they mistake them for actual video files. A major disadvantage of the .mpgindex format is that it contains zero media data - no video, no audio. It is completely useless without the original MPG or MPEG file stored in the same directory. Furthermore, these cache files often clutter hard drives and annoyingly litter project folders.
Because this is not a media file, you cannot convert it into standard video targets like MP4, MOV, or AVI. Converting it to a plain TXT file or inspecting it in a hex editor may allow you to view the raw frame offset data, but it will not give you a playable video.
This file format is difficult to open or convert because it is a closed, proprietary data structure designed exclusively for internal use by Adobe rendering engines. Standard online converters fail to process it because they expect video streams that do not exist. If our analysis detects supported underlying text or embedded data, viewing or conversion may still be possible.
Convert.Guru analyzes your MPGINDEX file, detects the exact format, and lets you read the text inside.
If you want to convert MPGINDEX file to MP4, AVI, MOV, WMV, FLV, WEBM, MKV, M4V, 3GP, OGV, ASF or RM, you can use Adobe Premiere Pro or similar software from the "Video Cache Indexing" category. In the File menu, look for Save As… or Export….
To convert MTS, MOV, RMVB, DIVX, RM, H264, TS, WMV, VOB, MP4, XVID or AVI files to MPGINDEX, try Adobe Premiere Pro or another comparable tool in the "Video Cache Indexing" 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 MPGINDEX converter.
