There have been numerous cases of CRC error. CRC short form of cyclic redundancy check is a technique for detecting errors while transferring data. CRC error simply indicates that the file is damaged. When you transfer a file from one system to other or download a file from internet, your computer makes a calculation for all the data in the file to ensure originality. Computer compares the CRC value of the original file to the value of the file being transferred to another system. If these two values differ, the file that was transmitted does not match the original file, and your computer displays a CRC error message.

Irrespective of the file type a CRC error indicates damaged data, and it is not possible to access that file for further use. For example take an instance you copied a movie with .avi file extension, while running the file OS prompt with CRC error. But sometimes it may play fine in any particular media player and not so good in another.

All it takes is only one bit in one byte to generate a CRC error. So if your video is working fine then you don`t need to worry a lot. However, one bit within one byte will not be seen in a video.

Why CRC error occurs?

In normal computer usage CRCs are most generally generated when you "transfer" data from one place to another (i.e, disk to memory, memory to disk, memory to application, or disk, etc). When the receiver does a CRC check on the received data stream and if it is not the same as what the sender sent you, then normally a CRC error is raised and depending upon the level of sophistication built in either a retransfer happens or processing stops.

Some typical causes are noise on the line (sometimes called burst errors and most CRC algorithms will account for some classes of this type but not large amounts). The sender and receiver not using the same CRC algorithm (rare but it does happen). Some other possible causes include exposure of media to excessive temperatures or magnetic fields, cross linked disk sectors, and mechanical problems with disk drives.

How to Fix CRC Error AVI file?

The catch is you have some missing data in this AVI file which can be recovered using AVI Mac repair. Go with Repair AVI Mac tool that helps you repair AVI video file errors and restores all the data from it.
