如今，制作和分享视频的方式已经走过了漫长的道路。除非您是专业的YouTube(YouTuber)用户，否则 2K 或 4K 等高质量视频似乎很浪费，而且有点矫枉过正，因为大多数视频都用于休闲娱乐和分享目的。如果您确实遇到太大而无法共享或上传的视频，您可能需要减小其大小。所以今天，我将建议一些您可以轻松做到的方法。我将讨论免费软件以及免费的在线工具。
什么会影响视频的大小？
在不影响其质量的情况下减小视频大小的两种最常见方法是修剪素材或从视频中删除音频。您可以降低视频的分辨率，但这会影响其质量，尽管工具和软件会尽最大努力将影响降到最低。您选择使用的分辨率在很大程度上取决于将在其上播放视频的设备。您的设备（例如电视或家用投影仪）的屏幕越大，您需要的分辨率就越高。因此，应该相应地修改他们的视频。
还有其他几个因素可以在各种视频大小中发挥作用，例如视频编解码器和比特率。视频(Video)比特率是视频每秒使用的数据量。不同(Different)的视频需要不同的比特率才能在不损失质量的情况下进行流式传输，具体取决于它们的分辨率和帧速率。视频编解码器用于对视频进行编码并压缩其数据。不同(Different)的编解码器提供不同的压缩比，具体取决于视频的内容。例如，H.265编解码器提供比H.264编解码器高 50% 的压缩比。

ShotCut免费视频压缩软件
ShotCut是一个成熟的视频编辑工具，广泛用于有效地缩减视频大小。要在ShotCut上编辑视频，您必须按照以下步骤操作：
- 下载(Download)并安装ShotCut，打开它并使用“打开文件”选项导入视频文件。
- 在右上角，您会找到一个名为“导出”的选项，单击该选项将打开大量选项。
使用H.264配置文件足以减小视频大小而不会过多地放弃其质量，这就是ShotCut本身声称为大多数用户完成的工作。
- 您可以在导出设置中找到压缩视频的选项。您可以使用分辨率和纵横比。您应该记住，除非您想要失真的视频，否则您会对配置进行相应的更改。
- 更改输出会自动修改视频的属性，假设您从HDV（25 fps 的 1080p 高清电影）转换为HDV（29 fps 的 720p 高清电影）。您的 FPS 和分辨率会自动更改，相应的大小也会自动更改。但是，小于预设分辨率将需要您手动计算适当的尺寸。
VideoSmaller免费视频压缩器在线工具
VideoSmaller与Mac和Windows兼容，是一款干净、易于使用的视频压缩工具。您会注意到的第一件事是，它首先让您对上传的视频使用较低的压缩级别。这将保持最佳质量，但不会减少尺寸。
或者，您可以选择缩放视频。这样做的选项就在低压缩设置的正下方，以具有所有可能尺寸的下拉列表的形式。这会影响您的视频质量，影响的重要性取决于您选择缩小多少，但它会大大减少文件大小。
底部是一个选项，您可以消除视频中的任何声音。如上所述，这与文件大小有关。因此，如果您的视频不需要音频，您也可以检查此设置。在您可以上传视频的窗口上会警告说VideoSmaller最多只能拍摄 500MB 的视频，但这并不值得担心，因为它需要数小时和数小时的镜头才能从智能手机等拼凑 500 兆字节。VideoSmaller还声称将您上传的视频保留在其云端，也就是说，您上传的任何视频都将在您完成工作几个小时后从其服务器中删除。去这里(Go here)使用这个工具。
您可能会遇到一些问题，例如网站上塞满了广告，或者一次只能处理一个视频，在这种情况下，您有多种选择，例如VideoSolo、YouCompress等。在您想要转换的情况下将DVD转换为MP4或MKV视频，HandBrake是派上用场的工具。
How to reduce video file size in Windows 11/10?
The way in which videos are made and shared these days have come a long way. Unless you are a professional YouTuber, high video qualities like 2K, or 4K can seеm wasteful and a bit of an overkill, since most videos are used for casual recreational and sharing purpoѕes. In a case where you do come aсross a video that iѕ tоо big to be shared or uploaded, you may want to reduce its size. Ѕo today, I’ll be suggesting some hassle-free ways in which you can do so. I will be discussіng freeware as well as a freе online tool.
What impacts a video’s size?
The two most common ways in which you can reduce a video’s size without impacting its quality is by either trimming the footage down or removing audio from the video. You can bring your video’s resolutions down but that is going to take a toll on its quality, although tools and software try their best to make the impact as minimal as possible. The resolutions that you choose to go with largely depend on the device that your video will be broadcasted on. The bigger the screen of your device, say television or a home projector, the higher the resolutions you would need. So, one should make modifications to their videos accordingly.
There are several other factors that can play a role in the varied video sizes like video codec and the bitrate. Video bitrate is the amount of data that is used by a video per second. Different videos require different bitrate to stream without losing their quality, depending on their resolution and frame rates. The video codec is used to encode a video and compress its data. Different codecs provide different compression ratios, depending on the contents of the video. For example, the H.265 codec offers a 50% better compression ratio than the H.264 codec.

You can reduce video size without losing quality. Using this free video compressor software or online tool you can make video size smaller.
ShotCut free video compressor software
ShotCut is a full-fledged video editing tool used by people far and wide to efficiently cut down on the size of their videos. In order to edit a video on ShotCut, you have to follow the steps mentioned below:
- Download & install ShotCut, open it and import a video file using the ‘Open File’ option.
- On the top-right corner, you’ll find an option by the name of ‘Export,’ clicking on which will open a plethora of options.
Using an H.264 profile is good enough to cut down on the video size without giving up too much on its quality, and it is what ShotCut itself claims to have done the job for most of its users.
- It is in the export settings that you will find options to compress your videos. You can play around with the resolutions and the aspect ratios. You should keep in mind that you make proportionate changes to your configurations unless you want a distorted video.
- Changing the output automatically modifies the attributes of the video, suppose you shift from HDV (1080p HD film at 25 fps) to HDV (720p HD film at 29 fps). Your FPS and resolution will change automatically, and so will your corresponding size. Going smaller than the preset resolution, however, will require you to calculate the appropriate dimensions manually.
VideoSmaller free video compressor online tool
Compatible with both Mac and Windows, VideoSmaller is a clean, easy-to-use video compressing tool. The first thing you’ll notice is that it first offers you to use a lower compression level on the video you upload. This would maintain the best quality but won’t reduce the size as much.
Alternatively, you can choose to scale your video. The option to do so is right below the low compression setting, in the form of a dropdown with all possible dimensions. This would impact your video quality, the significance of the impact would depend on how much you choose to scale it back, but it would reduce the file size considerably.
On the bottom is an option for you to rid the video of any sound. This, as mentioned above, has bearings on the file size. So, if your video is something that isn’t in any need of audio, you can check this setting too. On the window where you can upload your video is a warning that VideoSmaller can only take videos up to 500MB, but this isn’t something to be worried about, because it takes hours and hours of footage off of, say, a smartphone, to rag up 500 megabytes. VideoSmaller also claims to keep your uploaded videos off of its cloud, i.e., any video you upload will be removed from its servers a few hours after your work with it is done. Go here to use this tool.
You may experience some issues, like the website being too stuffed with ads, or that it can only work on one video at a time, in which case you have several alternatives like VideoSolo, YouCompress, etc. In a scenario where you want to convert a DVD into an MP4 or an MKV video, HandBrake is the tool that would come in handy.
