Download 99% and get stuck. Don't worry! After learning how to repair the video, it will not be in vain for dozens of hours. Please follow us and turn the incomplete video into a treasure.

The reason why I want to play

A movie file consists of three parts: File Header, data block, and index block. The data block contains the actual data stream, that is, the sequence data of images and sounds, which is the object body. Index blocks include the list of data blocks and their locations in files. They are responsible for ensuring random data access in files. The file header includes common file information, defined data formats, compression algorithms, and other parameters.

If any part of the file is damaged, the playback is abnormal. The most common reason is that the file header is damaged during the download process. For example, we use the software that supports resumable download, during the download process, files may be incomplete due to abnormal restart. Another reason is that many Movie Download servers have made some effort to prevent multi-point downloads. The tool software for downloading streaming media often lacks some necessary mark data during file reconstruction, this prevents normal playback.

In addition, if a proxy server is used during the download process, the downloading may be incomplete. Another reason is that the video files are incomplete due to problems during the splitting and merging process.

The easiest solution is single-threaded download of HTTP or FTP. Many films downloaded to 90% or later are only download completed, but the extension name cannot be changed to the actual type.

Effective repair tools

RM repair requires re-Indexing

RM file damage is usually caused by index data problems. You only need to rebuild the index data. RMFix can repair the RM files that cannot be played or are not completely downloaded, and re-index the RM files that cannot be dragged for playback so that they can be played freely.

Method: drag the RM file to be repaired to the RMFix program icon. At this time, RMFix runs in DOS mode and displays a menu. Press the "R" key to recreate the index data. For RM files that can only play A part of the image, press the "A" key to switch to the automatic repair mode, and press the "2" key to start checking all data blocks, RMFix scans the entire file and fixes corrupted data blocks. After that, re-create the index data, and then the RM file can be played normally. Once the RM file is damaged, you can use RealMedia Analyzer to fix it: start the program to enter the DOS operation interface, and enter "rma-f aaa. rm "command, so that the RMA program can automatically scan video files. When there is a bad data block during the scanning process, it will automatically repair until all the data has been completely repaired.

DivX needs to be rebuilt

We can use DivFix to fix common DivX files. It allows you to watch undownloaded DivX (AVI) movies, rebuild error indexes in files, and perform error detection to automatically check error messages in audio/video streams. After importing the incomplete video file to the DivFix program, click "Rebuild Index". DivFix creates an Index for the file, you can quickly forward, backward, or drag the time bar with the mouse. To fix ASF and WMV files, we usually use ASFTools. After running the software, click "Add" to Add the files to be processed, next, you only need to press the "Make Seekable" button and "Repair" button to start ASFTools to fix the selected file.
