Nowadays video converters have become more user-friendly than ever before, and in most cases all you need to do is add the video and pick the format that you want. However as simple as it may appear on the surface, there are intricacies involved when you convert the format of videos – and if you aren’t careful even the video quality may be affected.

That is why as far as possible there are 3 best practices that you should remember – and follow:

  • Do not convert the same video’s codec repeatedly

Every time you convert a video from one codec to another the data is recompressed. That means that the compression of the new codec is applied to it, and some of the video’s data that is considered redundant will be discarded due to the nature of ‘lossy’ compression .

If you convert the same video file over and over again, that process is repeated each and every time. Eventually the amount of data that is discarded will start to affect the video quality, and cause it to deteriorate.

  • Keep the original video and store it safely

The original version of your video is the highest quality copy of it that you will possess. Because of that you should try to keep it and store it safely.

Not only will the original video act as a backup that you can use to restore your video, but it will also provide you with a master copy that you can use to convert the video. If you need to convert that video into a different format you can revert to the original and convert from it.

That will let you avoid the problem of converting the video codec repeatedly.

  • Identify whether the video needs demuxing

<a rel=”nofollow” href=”http://adubvideo.net/informative/mux-demux-remux-huh”> Demuxing  </a> essentially involves splitting a video container back into its component streams. It is useful when you are converting video files that have been muxed (i.e. combined from several streams).

While it can get a bit complicated, the most common reason why videos may need to be demuxed is to extract the caption or subtitle track from the container. Different formats may not support captions and subtitles, or may support them in other variations.

By demuxing videos you can remove the subtitles and convert them separately instead of simply losing them completely.

The best practices described above should be used to convert any video files. For example you can learn how to convert MOV to MP4 using Movavi Video Converter and apply them along the way.

By applying each one, you will be able to preserve the quality of your video while you convert it. In the long term it will enable you to convert videos between formats far more effectively.
