Does Compressing Video Lose Quality?

When it comes to video compression, people always wonder does compressing a video ruin quality. Sadly, in most cases, compressing a video will downgrade the quality. The common video compressing methods, including re-encoding video into another format (lossy), changing the video bitrate, downscaling resolution, and reducing frame rate, will lead to quality loss inevitably. But by using a high-efficiency encoding format such as HEVC and VP9, you can compress video without losing any noticeable quality. Moreover, cutting out the unnecessary parts from a video is another way to make the video smaller without quality loss.

In the next part, we will see details of how to compress video without losing quality with a powerful video-size compressor. Please read on.

Step 3. Pick an Output Format

On the right side of the program, click to open the output format page and go to the “Video” section. Here, you can select your preferred format. MP4 is most recommended. But if you have trimmed your video, you are advised to keep the same format as the original.

Pick Output Format

Step 4. Choose an Advanced Encoder

* To trim video without losing quality, skip this step.

Now, open the “Parameter settings” below. Then, find the video Encoder option and choose H265 as the encoding format. Please note that only MP4 and MKV formats support the H265 codec. If you have chosen WebM as the output format in Step 3, you can use VP9 as the video encoder. Then click “OK” to save the settings.

Note. H265 and VP9 are not supported by some devices and applications. You can use the free VLC media player to open these files if you encounter a playback error.

Choose Output Format

Step 5. Start Video Compression without Losing Quality

Finally, choose an output folder at the bottom of the program and click “Run” to output your compressed video without quality loss.

Downsize Video without Losing Quality

Tips. If you are not satisfied with the output file size, you can try other ways to reduce video MB to an even smaller size, such as decreasing the video resolution, bitrate, and framerate. But that will lead to some quality loss. However, if you compress a video from high quality/bitrate, you may not interpret much difference on a small screen.

Now, download download the video compressor software to complete your work!
