Being able to convert the formats that are used to store your video files can be very useful. It can help you to ensure they are compatible, compress and reduce their file size, and preserve their quality.
However many people often make mistakes when converting video formats that could affect the quality of the video, its compatibility, or other areas. Needless to say you’ll want to avoid these mistakes, which is why it helps to know the more common issues:
Transcoding the same video multiple times
Every time you transcode a video by switching the codec in its format from one to another – some data is inevitably lost. As such if you transcode the same video file multiple times between different codecs, more and more data will be lost over time and it will affect the video quality.
To avoid this it is recommended that you keep a copy of the original version of the video. That way every time you need that video file in a particular format, you can go back and transcode it from the original – minimizing the data that will be lost.
Not checking for hardware support
While a video may be able to be played on a particular device because it has software support – that often isn’t enough. The fact of the matter is that decoding videos using software alone is processor-intensive and requires a lot of power.
That is why it is important to check for hardware support when considering the format that you want to convert your video to. In particular for mobile devices it is impractical to use formats without hardware support, as watching them will have a big impact on your battery life.
Using the wrong video bitrate
If you convert a video format to a new codec, it may require a different video bitrate. Simply put the video bitrate depends on the compression that is used, and for example H.265 (HEVC) videos require about half the video bitrate of H.264 videos.
The reason it is important to avoid this mistake is that it can affect the file size or quality of your video. If the bitrate is too low various types of compression artifacts will appear, whereas if it is too high the file size will be much larger than it needs to be.
The next time you convert a video, be sure to avoid the mistakes listed above. If you’re just converting the container (but not the codec) you normally don’t have to worry about most of them, for example if you use Online Video Converter (www.videoconverter.com) to convert a video to MP4 without touching its codec.
All said and done none of the mistakes listed above are that hard to avoid once you know about them – so it shouldn’t be that difficult. By making sure you avoid the mistakes, you can enjoy the benefits of being able to convert videos without having to worry about adverse effects on its quality or compatibility.
