How to Change Video Container without Losing Quality?

Launch HD Video Converter Factory Pro and open the “Converter.” Click “+ Add Files” to load the needed videos. You can also drag these files into the converter directly.

Click the right-side format image to open the format library and then select one appropriate format as the output format. Remember that the selected format must support the encoder used in the original file. For example, to remux an H.264 encoded MKV file, you can choose MP4 or MOV as the output format.

The program will automatically smart fit the best settings for your conversion after you selected the output format, usually with the same encoder, same resolution, etc. But you should double-check the parameters in the “Parameter settings” and ensure everything matches the source settings. You will see a lightning icon appear at the conversion list when the video is ready for remuxing.

Click the ▼ button to set an output path. When everything is ready, hit “Run” to start changing the video container without encoding.

Click “Edit…” and add the FFmpeg binary directory to the path, e.g.  C:\ffmpeg\bin. Then click “OK” to save the changes.

Step 4. Type “cmd” in your system search bar to bring up “Command Prompt.” Then input “ffmpeg -version” and press Enter to see if the configuration is done.
