If the corruption is massive, however, it may be beyond a video converters ability to salvage it, or what is salvaged may be too short to be usable, or end up simply being an unusable section of the video. However, if a video file is not playing due to a bad index, the lack of termination, or has some slight corruption internally, it can often be saved by using a video converter program. Only when it is recoded by a video converter program will it be able to be played by the new formats video program that it is then associated with. You need to actually convert the file to a new video format, so it is coded in the new formats language. So, you can't simply change a video file's extension to a different one. (There are only 2 exceptions I know to this basic rule, and they are not video files). I only use the full licensed versions of desktop applications for video conversion, as they do not have file size limitations, and can rebuild file indexes as they perform their conversions.Īs far as just renaming files to other formats - you can't simply change a file's extension to a different one, because the extension indicates the formatting (the 'language') that the file is coded in, and is associated with the program that a video file needs to decode it in order to play properly.

Yeah, I never use online video converters because they usually have file size limitations, and they often have problems doing a conversion from any files that do not have proper termination and good indexes already in place.
