The first thing you should do is just "doubleclick" on the H263 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install MediaCoder

Programs to open H263 file

Remember to download programs supporting H263 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of MediaCoder with H263 files

However, it may happen that the application itself does not cause the H263 file to open in the MediaCoder application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the H263 file with the MediaCoder program.

Step 3. Update MediaCoder to the latest version

The fault may also lie with the MediaCoder program, it is possible that H.263 Video Format requires a newer version of the program. In this case, use the MediaCoderHQ website or update the program from the application.

Step 4. Check for the following problems with the H263 file

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The H263 file may be unusually small compared to the original file. Usually this applies to H263 files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our H263 file. As a result of the scan, sometimes it is not possible to recover H263 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the H263 files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged H263 files. The easiest way is to restore the file from a backup, if there is one, or contact N/A
The program indicates that the file is encrypted or corrupted. The encrypted file H263 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. If possible, you can try to move the H263 file to another location.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the H263 file while scanning. If nothing helps, please reset the device.
