How to Compress Video Files with WinX HD Video Converter Deluxe

Video files can get very large, especially when working with HD, 4K, high frame rate footage, or long videos. If your file is too large to upload, email, store, or share, you may need to compress the video and reduce the file size.

In this tutorial, we look at how to use WinX HD Video Converter Deluxe to reduce video file size while keeping the quality as high as possible.

Why Video File Size Matters

Large videos can be difficult to upload, send, or store. Some platforms also have file size limits. YouTube supports very large files, but huge uploads can take a long time. Other platforms, such as TikTok, Instagram, Facebook, and X/Twitter, may require much smaller files.

If you want to email a video, the file usually needs to be much smaller, often under 10 to 25 MB depending on the email service.

Can You Reduce Video File Size Without Losing Quality?

Any real video compression usually involves some kind of quality tradeoff. The goal is to reduce the file size in a way that keeps the quality loss as small and unnoticeable as possible.

What Affects Video File Size?

• Resolution – 4K video is much larger than 1080p or 720p video.
• Bitrate – lower bitrates can reduce file size, but may hurt quality.
• Codec – modern codecs such as H.264, H.265, AV1, and VVC can compress video more efficiently.
• Video length – shorter videos create smaller files.
• Frame rate – 60 FPS video is larger than 30 FPS or 24 FPS video.
• Aspect ratio – different formats, such as 16:9, 9:16, or square video, can change file size.

Best Video Settings for Compatibility

For most online video uses, MP4 with the H.264 codec is a strong choice because it is widely supported by video players, websites, and social platforms.

H.265, AV1, and VVC can offer better compression, but H.264 is still one of the most compatible options.

How to Compress a Video in WinX HD Video Converter Deluxe

Start by opening WinX HD Video Converter Deluxe and clicking the Video button. Choose the video file you want to compress and load it into the program.

In the example, the original video file was an AVI file with a size of 229 MB. The goal was to reduce that file size while keeping a good-looking video.

Choose an Output Profile

After loading the video, choose an output profile. For most uses, MP4 video is a good option. Avoid choosing a larger 4K output profile if your goal is to reduce file size, because that may make the file larger instead of smaller.

You can also choose platform-specific profiles, such as YouTube or Facebook, depending on where the video will be uploaded.

Trim the Video

One of the best ways to reduce file size is to shorten the video. In the Edit window, enable Trim and use the handles to remove unnecessary parts from the beginning or end.

In the demonstration, trimming the video from about one minute down to 29 seconds helped reduce the final file size significantly.

Adjust Resolution

Lowering the resolution can also reduce file size. For example, changing a larger video down to 1280x720 can create a smaller file while still keeping good quality for many online uses.

For YouTube, 1080p is a common standard, while 720p may be useful when a smaller file is more important.

Use Variable Bitrate

WinX HD Video Converter Deluxe allows you to use variable bitrate, or VBR. This lets the encoder adjust the bitrate as needed during the video, which can help balance quality and file size.

Be careful with bitrate changes, because lowering bitrate too much can cause a major drop in quality.

Use Hardware Acceleration and High Quality Engine

Hardware acceleration can help speed up the conversion process. The High Quality Engine option can help preserve quality during compression.

If you are trying to make a smaller video while keeping it looking good, turning on the High Quality Engine is a smart choice.

Final Compression Result

In the example, the video started at 229 MB. After trimming, converting to MP4, and adjusting the output settings, the final video was reduced to about 45.3 MB.

Your results will depend on the original video, how much you can trim, the resolution you choose, the codec, and the output settings.

Final Thoughts

WinX HD Video Converter Deluxe gives you several ways to reduce video file size, including trimming, changing resolution, choosing MP4 output, using H.264, and adjusting compression settings.

The best approach is to choose the settings that match your video’s purpose. A smartphone audience may not need 4K, while a nature documentary or large-screen presentation may benefit from higher resolution.
