Compress Video in Much Efficient Ways with Winxvideo AI (AI-powered)

  • Cut video size up to 90% off by simply dragging a slider thanks to its intraframe & interframe coding algorithm.
  • No noticeable quality loss after video compression with the help of High Quality Engine and de-interlacing engine.
  • Offer different ways to reduce video file size, cut/trim videos, lower down resolution/frame rate/bit rate, increase GOP, etc.
  • Unique Level-3 GPU acceleration tech makes the program compress 8K/4K/1080p video at 47X real time fast speed.

Way 1. Compress Video with VLC by Downscaling Video Resolution

First off, let's make it clear what determines the file size of a video. From the formula "video size = bit rate x duration", we can draw that bit rate and video length are the key points, with several other video parameters, say video codec, resolution, frame rate affecting the final size too. VLC can work as free video compression software. So, no more other words, just check how VLC compresses the file size of the video shot by iPhone, GoPro, DJI or digital camera by adjusting the key factors above in VLC video settings.

Before you resize video with VLC compressor, please DOWNLOAD VLC and finish the setup, then follow the steps below.

  1. Click "Media" -> "Convert / Save" or tap "Ctrl + R" keyboard shortcuts to pop up a smaller control;
  2. Add source (4K/HD) video into the file list;
  3. Click "Convert / Save" button to go ahead;
  4. Choose profile such as HD(720p) or SD(480p) or smaller file size.
  5. Rename output in destination folder and click "Start" to compress video in VLC at once.

Convert 4K to 1080p, 1080p to 720p, HD to SD

Scaling refers to changing/lowering down the resolution of video to reduce video size. In order to shrink video size in VLC, downscaling video is required. If you choose a profile with no SD or HD tag, like Video - H.264 + MP4 (TS), the resolution frame size will remain as original. So click setting icon right near profile and navigate to resolution to fill either of scale, width and height value to downscale source video. You can click 4K to 1080p/720p, or 1080p to 720p, 720p to D(480p) to compress video with VLC.

Compress Video with VLC by Downscaling Resolution

To make it easier for the novices to compress video for sharing online or watching on mobile/home TV, VLC presets 10 video profiles with resolution fixed in 1080p, 720p HD and (640x480) SD as shown in the screenshots. The difference between SD, SD Low and SD High mainly lies in video bit rate and frame rate parameters which will be specified in Way 2.

Way 2. Compress Video with VLC by Changing Video Encoding Parameters

E.g: H.264 MP4 -> H.265 MP4, 120/60 fps -> 30fps, 40000kb/s -> 8000kb/s

VLC's video compression feature empowers users to customize encoding parameters for reducing video file sizes while maintaining satisfactory visual quality. These parameters include quality control for better visuals at the cost of larger files, bitrate adjustment to influence data rate, frame rate reduction for smaller files, and resolution modification to decrease dimensions.

While primarily focused on video, VLC also provides options for audio configuration. Additionally, users can save personalized compression settings as profiles for convenient future use.

For 1080p (Full HD) videos, a bit rate between 5,000 and 10,000 kbps is often suitable for good quality. For 720p (HD) videos, a bit rate of 2,500 to 6,000 kbps is usually sufficient. For most standard video content, a frame rate of 24, 30, or 60 frames per second (fps) is typical. Common aspect ratios include 16:9 (widescreen) and 4:3 (standard). The choice of aspect ratio depends on the original content and the display you're targeting. Aspect ratio and frame rate don't affect the final video size too much.

VLC Compresses Video by Changing Video Parameters

Since 30 frames per second is enough for human eyes, it's available to compress high-fps video by lowering the fps directly to 30. Note that if the high-fps video is taken for slow motion, take care to decrease the fps before you post producing a favored slow motion video.

Video file size depends on its length and bitrate. Lowering the bitrate makes the file smaller without changing the video length. Generally, 4K video looks clear and smooth when streaming at 35Mbps or higher, 1080p at 8000kbps, 720p at 5000kbps, 480p at 2500kbps, 360p at 1000kbps...

Way 3. Compress Video Size in VLC by Altering Audio Encoding Parameters

VLC also enables user to reduce video file size without losing video quality by resetting audio codec, bit rate (to 128 kb/s), sample rate and channels in VLC video and audio settings. The audio settings are available under the Audio Codec tab. Click the Audio codec tab, check the box next to the Audio to get audio setting options.

Note that audio doesn't have much influence on the total video size. If you don't want to set audio parameters, leave it alone. When you only need the audio file, it's a good way to extract the audio from your video for much shrinked file size.

Way 4. Compress Videos in VLC without Losing Quality by Trimming/Cutting

VLC does not support cutting or trimming video for removing unwanted video part off. Therefore, you can alternatively "cut" video content by recording the important or necessary clips only with "Record" feature under playback. In this way, you can compress video size with VLC without losing quality. Drag the video to the start point you want to keep, play the video, and click the red recording button, after the video reaches to the ending point, click the recording button again.

Way 5. Compress Videos in VLC by Converting Video Format

Embracing all media formats supported by FFmpeg libavcodec and libavformat libraries, VLC is able to recognize and transcode a variety of videos to H.264/HEVC MP4/MKV, VP8 Webm, WMV, AVI, FLV, ASF, MP3, MPEG etc. (Check VLC Format Support from Wiki).

Generally H.264 MP4 is the go-to pick for its wider compatibility and better balance between file size and quality. But sometimes if the end player or social site supports HEVC, or you just shrink video for saving space, it's more recommended to downsize large video to H.265 MP4, because the High Efficiency Video Codec / H.265 codec achieves the same quality as H.264 with only half the size. If you can accept HEVC compatibility, you can choose to convert H.264 to HEVC for higher data compression ratio.
