Best Video Reducer Software: Resize 4K/2K/1080p Video from GoPro/Action Cam/iPhone/Drone

The original video footage doesn't come on the scene in a way that you want. Its video size might exceed your expectation; the video image size is probably incompatible with your playback device and the footage length goes beyond the limitation of some video sharing platforms. In such case, you need a video resizer software to help you reduce video clips shot by smartphone (iPhone/Android), action cam (GoPro), camera/camcorder, monitor, Drone and more. To losslessly downsize your hi-res 4K/2K/1080p video footages, VideoProc cuts the buck.

Fast and Smooth: VideoProc supports you to load whatever video/audio inputs for video reduction. It can resize MP4, MOV, M4V, MKV, AVI, as well as 720p/1080p/4K video produced by GoPro, action cam, camera, iPhone, Android, Drone, monitor unit, computers and tablets without any CPU overheating or deaktop laggy issues, for it sports with the advanced Intel QSV/Nvidia/AMD Level-3 GPU hardware acceleration techs to hand over the computation-intensive tasks from CPU to the graphic processing expert GPU. Thus, the whole 1080p/4K video reduction mission can go quickly and smoothly, no any burden on CPU.

All-round and Easy: This video resizer program covers almost all the video compression features. To be specific:

1. Cut, Trim & Split: they're available for you to badly resize video, esp. for long survelliance video, camcorder video, action cam GoPro video like 2 - 5 hours.

2. Crop: enable it to use the marquee box to easily shrink the video image size so as to reduce video size.

3. Change video resolution, frame rate & aspect ratio: downscale 4K/2K to 1080p/720p, lower 240FPS to 120FPS, 60FPS to 30FPS, tweak 16:9 to 4:3/3:2/1:1.

4. Transcode video codec from H264/MEPG-4/VP8 to HEVC/VP9 with much higher video compression efficiency, at least 50% smaller than before.

How to Resize a Video with VideoProc

Step 1: Free download VideoProc on your computer.

First things first, get this video resizer program downloaded on your desktop. Afterwards, install and launch it on your computer.
Free download VideoProc on Windows 10/8/7
Free download VideoProc on Mac OS X 10.6 or above

Step 2: Load the video file you wanna reduce.

Tap on the "Video" on the main panel to navigate to video processing interface. Click "+ Video" icon at the top menu of the window to import your video file.

Bulk video processing is supported, as well. You can choose to press on "Ctrl" key (for instance) on Windows to bulk import several video clips or hit "Video Folder" to add a video folder into this video size reducer. Then you can opt for the proper methods listed below to downsize your video. You don't have to use them one. Instead, apply the ways that best suit your video sources.

Method 1: Cut off Superfluous Clips from Your Video.

Tap "Cut" button on the editing bar below video input & output info > you'll be directed into the video cutting interface, where you're allowed to drag the green knob to set the start and end time of your video clip to remove the unwanted clips from video and just keep your desired clip > then click the orange "Cut" button > lastly hit "Done" button and it will go into action.

Note: generally, your iPhone or Android smartphone recorded videos don't seem too long in video length. You probably cut iPhone video or Android clips because of the video start or end part. Things are different with videos recorded by action cam GoPro, Drone, monitor unit and other camcorders. They usually shoot a video around 2 ~ 6 hours or even longer. Therefore, you have to cut a long video into several clips to get what you want. So this video reduction feature is a must have for whatever video sources.

Method 2: Trim Video to Get Your Desired Part.

Unlike the above Cut feature, "Trim" doesn't enable you to slice your whole video into several parts. It only supports you to trim a video and get one desired part at a time. If you just need one certain part of your 4K/2K/1080p video for sharing to Instagram, Snapchat, YouTube or Emailing, "Trim" fits the bill.

Find "Toolbox" at the bottom of the interface > click "Trim" and its setting icon at the upper right corner of the option to pop up the trim window > still drag the green knob to freely control the start/end time to get your desired part > tap "Done" after you select the video clip.

Method 3: Averagely Split a Large Video into Small Parts

In case the video you possess has the same video duration at each timeline, you can choose to averagely split a large-sized video into 5/10/20 segments or split a video every 1/10/30 minutes to shorten video length and resize GoPro 4K video, surveillance video, downloaded TV series/TV show and more.

Method 4: Crop Video Image Size to Shrink Video

The adjustment of frame proportion in the video can also help you reduce iPhone video, action cam GoPro footages, Drone video, etc. and change video aspect ratio to the one you need. Click "Crop" icon at the video info panel > tick "Enable Crop" > freely move the marquee box (show as below) to get your desired video image and correspondingly downsize 4K/1080p MP4 or MOV video. The output video size is clearly display thereon after you tweak.

Given that the free adjustment would lead to the non-standard video image like 2700x1736, 1874x924, which can't perfectly fit your playback device, you can take the preset settings into consideration. Beyond the default "Free" model, there are more 6 options available: Crop LetterBox, Keep Current, Keep Origin, 16:9, 4:3 and 1:1. Choose the one preset you require to customize your 4K/2K/1080p full HD video image with proper aspect ratio. BTW, the "Expand Video" option is accessible for you to add black bars to both sides of the video (top/bottom or left/side) to stretch your video.

Method 5: Lower 4K Video Resolution and Frame Rate

4K 2160p has roughly 4 times more pixels than 1080p, which results in 4 times larger than 1080p in file size. And the 4K video size would be expanded to even larger when it comes to 4K video at higher frame rate like 50FPS, 60FPS. So if you're inclined to further compress GoPro/camcorder/Drone/iPhone/Android video footage, lower video (4K/2K/1080p) resolution and frame rate as follows:

Hit "Codec Option" icon at the video info panel > tap the extension icon of resolution under "Video Codec Options" to select the video resolution you want, e.g., 2560x1440 (2K), 1920x1080, 1280x720, etc. > the same applies to opt for frame rate, be it 60FPS, 59.94FPS, 50FPS, 30FPS, 29.97FPS, 25FPS, 24FPS, etc.

Optionally, you can also adjust the video Bitrate from the default mode "Auto Calculate" to "Manual" mode > tick "CBR" mode > properly lower target bit rate (kbps) around 20% - 40% to strike the delicate balance between video file size and video quality.

Method 6: Change Video Codec to Make Video Smaller

Another common way to resize video is the video codec conversion. With this all-sided video resizer software, you're given with maximum freedom to transcode H264 to HEVC (at least 50% size off), MPEG-4 to XviD/DivX, MPEG-2 to WMV2/FLV/VP8, etc. with better suitable video codec and smaller video size.

Move your mouse to the bottom of the home screen > tap "Video" > choose the video codec and format you prefer. Or directly press "Target Format" to make the pop-up output format dialog visible. Then you'll be greeted with more than 420 preset profiles, not only the general profiles (H264, HEVC, AVI, MKV, FLV....), but also the latest device profiles included (iPhone Xs Max/Xs/XR, Huawei Mate 20 Pro, Galaxy S9 edge, Sony flagship model, PS4, Xbox One, Google device...).

Method 7: Ditch Away Unnecessary Video/Audio/Sub Tracks from Multi-track Video

You would be surprised to find that some videos downloaded from online websites have multiple video, audio or subtitle tracks. And most of them actually mean nothing to you except larger size. In such case, you can take advantage of this video reducer program to remove unwanted video/audio/subtitle tracks from video to compress video file. And it's a no brainer to delete reduntant tracks from video:

Place your mouse at the video detailed info window, where you click the expansion symbol to select the video track(s) you need. The same can be used to choose audio and subtitle track(s). Thus, your video is only covered with the useful video/audio/subtitle tracks, no superfluous yet space-consuming tracks remained.

delete unwanted tracks from video
Step 3: Choose output folder.

Find "Output Folder" at the lower right corner of the interface and tap "Browse" to select the destination folder for your outputs.

Step 4: Resize your video now!

Hit "RUN" button and its video compression engine will go into action to begin resizing your video (MP4/MOV/M4V...) with highest possible quality. If your computer supports GPU hardware acceleration (check "Option" under Hardware Acceleration Engine. If it's available, tick the box of Nvidia/Intel/AMD), the whole video reduction procedure would be finished mainly on the graphic processing expert GPU, up to 5X faster than any other toolkits.
