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. Video compression can be either lossy or lossless. If you expect small video file size with original video quality preserved, the lossless video compression algorithms will help you achieve that. So, what is lossless video compression and how does it work?

Video Compressor for Beginners

WonderFox HD Video Converter Factory Pro is an easy video compressor offering lossless and lossy video compression options at the same time. It has optimized presets, which is easy for new users to reduce video file size while keeping good video quality.

Part 1. What is Lossless Video Compression

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 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.  

Video 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. Before starting lossless video compression, let’s learn about these popular lossless video codecs.

Part 2. Best Lossless Video Formats and 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 editing or conversion program that supports one of the video coding formats above for lossless video compression. 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 video compression codecs are for video editing and rendering, and don’t have all-round compatibility. The popular video compression standards, H.264 and H.265, however, can implement lossless video compression and are supported on many video compressors.

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.

Part 3. How to Achieve Lossless Video Compression

No matter you want to carry out lossy or lossless video compressions, 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 video compression while offering quick settings for you to compress videos 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.

WonderFox HD Video Converter Factory Pro
  • Convert videos to lossless H.264 and H.265.
  • Advanced parameter setting options to resize videos.
  • Quick compression option for one-click easy compression.
  • Cut, crop, and split videos to remove unnecessary sections.
  • Also offer other tools including video downloader, recorder, GIF maker, etc.
  • Here is how you can easily convert videos without losing quality in WonderFox HD Video Converter Factory Pro.

    Step 1. Open Converter

    Start HD Video Converter Factory Pro. There are 5 function modules. Select Converter.

    Step 2. Import the Videos

    Click +Add Files, select the videos you want to convert, and click Open. You can optionally drag videos into the Video Converter window for importing, as well.

    Step 3. Choose H.264 or H.265

    Click the format icon on the right side, go to Video, and select H.264 or H.265 for MP4. Generally, the latter can achieve up to 50% better data compression with the same video quality but the conversion time will be longer.

    Step 4. Start Lossless Video Compression

    Click the triangle icon on the bottom to designate the output path. Finally, click on Run.

    Bottom Line:

    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.
