What Is Lossless Video Compression and How to Convert Videos Losslessly?

A significant character of uncompressed media files is extremely large file size. With the intention of saving more storage space, many people are inclined to compress such videos by re-encoding. However, compressing a video can be either lossy or lossless. If you expect a small file size yet the original video quality, the lossless compression algorithms will help you achieve that. So, what is lossless video compression and how does it work?

Lossless video compression removes statistical redundancy without losing any data information, which uses fewer bits to encode data and consequently makes file size smaller. Compared with lossy video compression that deletes nonessential details, especially the components invisible to the naked eyes, to realize smaller file size, lossless video compression schemes are designed to keep intact quality while reducing the video file size.

Nevertheless, lossy video compression provides more possibilities to greatly reduce video file, but it is always at the cost of quality and tradeoff is an essential ingredient during the process. Unless you want to substantially free up your device storage or need to distribute “finished” videos on the network, it is more advisable to utilize lossless video compression, especially when your videos are still in the editing process.

Before the compression, let’s learn about some popular lossless video codecs. The codecs used for video compression is a crucial factor affecting the output file quality and size. There are different video compression standards on this filed, covering both lossy and lossless video codecs.

• H.264 Lossless
• H.265 Lossless
• Motion JPEG 2000
• JPEG XS
• FFV1
• VC-2 HQ lossless
• HuffYUV
• Lagarith
• Apple QuickTime Animation (RLE)
• Alparysoft Lossless Video Codec
• Autodesk Animator Codec

You can use a specified video conversion or editing program that supports one of the video coding formats above for compressing videos losslessly. For example, FFV1 is included in ffdshow and LAV Filters libraries so you can encode videos using it with most non-linear editing software, such as Blender, Adobe Premiere, and VirtualDub. QuickTime Animation format is supported on After Effects. It is also feasible to create HuffYUV files in ffdshow, VLC media player, and so forth.

Most lossless codecs are designed for video editing and rendering, and don’t have all-round compatibility. The popular video compression standards, H.264 and H.265, however, are supported by many applications and can implement a lossless compression easily.

If you need an easy solution to carry out the process or need device and platform friendly outputs, here is a good way to go.

No matter you want to carry out a lossless or lossy video compression, a program with the video encoding feature is necessary. WonderFox HD Video Converter Factory Pro is a simple yet powerful video compressor for Windows 10. It supports both lossless and lossy compression, offering quick settings for you to compress video files in the simplest way. There are no obscure terminologies or intricate process. The compressed videos can be easily shared, edited, stored, and used for other purposes.

This post has told the definition of lossless video compression, its implementation, as well as how you can carry out the process more easily. One thing needs to be noticed that lossless video compression is more applicable to uncompressed video data. If the quality of video source you want to convert is lossy, there is no way to improve the video quality to lossless one. If you persist in the action, you would not get good outputs but videos at the same video quality with even larger file size.
All in all, WonderFox HD Video Converter Factory Pro offers an easier and more efficient solution for video compression. Why not give it try?
