Video Processing: How to Compress Large 4K/2.7K GoPro Videos While Retaining Great Quality

Fast compress large 4K/2.7K GoPro videos to free up storage space, to share and upload to YouTube, Facebook easily and quickly, to send via email, to play back smoothly, etc.

"I'm trying to figure out how to compress GoPro 4K videos for storage and uploading to YouTube. They are coming out at about 6 gigs each for a 15 minute video, and it is going to add up fast."

GoPro cameras are very popular with those having deep love for outdoor explorations, extreme sports and so on. This is because such cameras are small, portable, waterproof and support superview, video stabilization, noise reduction, high-definition video recording, etc. GoPro users can even capture 2.7K and 4K videos on HERO3, HERO 4 Silver/Black, HERO5 Session/Black, and HERO6 Black, with varying fps. Such 2.7K and 4K videos are super clear.

However, every coin has two sides. Those super-high-definition videos will put heavy burdens on your storage devices, players, or other applications, making storage device running out of space quickly, media player (i.e., VLC) unable to play these GoPro videos smoothly, video editing or other programs failing to recognize and process them, etc. Plus, it will take us a very long time to upload such high-resolution large video to YouTube, Facebook and the like. Therefore, demand for compressing 2.7K/4K GoPro videos arises.

So, how can we zip big 2.7K/4K GoPro video files for email, for YouTube/Facebook/Instagram uploading, for fluent playback, or for other purposes? VideoProc can act as a GoPro video compressor.

Apart from showing how to downsize 2.7K/4K GoPro videos with VideoProc, we'll also explain how to compress 2.7K/4K GoPro videos with HandBrake and why we don't recommend compressing GoPro videos online as your reference.

Part 1. How to Compress 2.7K/4K GoPro Videos with VideoProc

To begin with, we need to download and install this compression software on our computer. The download links are attached below.
Free download GoPro video compressor for Windows (10 and lower)
Free download GoPro video compressor for Mac (10.13 and lower)


1 Open target 2.7K/4K GoPro videos on this compressor.

After launching VideoProc, click Video button to get access to video converter. Next, click +Video button to browse and open target GoPro videos or simply drag and drop them into the screen for later compressing.

2 Choose an output profile for resized video.
select output for compressed GoPro video

You'll find some popular output profiles at the bottom of the screen. Click Target Format to get more presets. Those ready-made presets come with different video audio codecs, resolutions, container formats, etc., to meet different user needs.

* If your to-be compressed 2.7K/4K GoPro videos are encoded with H.264, you can choose HEVC profile. By converting H.264 to HEVC/H.265, your GoPro video file will be reduced by about 50% without sacrificing quality. >> Check GoPro video format for 4K

* If you want to compress GoPro videos for YouTube, the test data below may help you choose a YouTube profile.
The two YouTube output profiles deliver different file sizes when we compress a 4K (3840x2160) GoPro video (833 MB) to 720P (1280x720).
YouTube Video -> MP4 (h264+aac): file size - 162 MB
YouTube Video -> FLV (h264+mp3): file size - 119 MB

3 Lower resolution and other parameters.

Click Option icon and then you'll be able to tweak the video audio parameters. Every item offers a drop down list for you.

* To choose a lower video resolution, simply get access to the drop down list and choose your desired resolution, 1920x1080 for instance.

* Bitrate is also another main factor influencing file size. So lowering the bitrate is also of great help to reduce GoPro video file size. Don't set bit rate too low, otherwise you will get an inferior video quality. Actually, the bit rate of some profiles will be altered automatically according to the resolution you choose. The software developer has chosen the ideal bit rate for you. Certainly, you can also change it as needed.

* As for frame rate, you'd better keep the original frame rate because lowing frame rate may lead to less smoothness.

4 Enable Crop/Trim to compress 2.7K/4K GoPro videos.

Click Crop and Cut buttons to step into video cropping and trimming interface.

* Select Crop, check Enable Crop, and then you can drag the lines in preview window to cut off unwanted area. Or, move the up and down arrows of Left, Top, Width and Height.

NVIDIA/Intel/AMD hardware acceleration will be enabled automatically to boost GoPro 4K/2.7K video compression speed if VideoProc has detected that your computer has the proper hardware.


5 Begin compressing 2.7K/4K GoPro video.

Just click RUN button and the rest work will be handed over to VideoProc. In addition to hardware acceleration, this program will also take advantage of MMX-SSE, Hyper-threading and AMD 3DNow! tech to quicken video resizing.

Now it's your turn to download the program and process GoPro video file compressing.

Part 2. How to Compress 2.7K/4K GoPro Videos with HandBrake

Considering that some people get used to HandBrake, we will illustrate how to compress 2.7K/4K GoPro videos with this free open-source video transcoder. Here, let's take the operation on HandBrake Windows version as an example.

Step 1. Launch HandBrake and click File to choose a single 2.7K or 4K GoPro video for further compression.

Step 2. Click Browse to specify the save path and the name for resulting file.

Step 3. Choose a preset from the far-right side of the HandBrake window. You'd better select a preset that falls at or below your GoPro video's current quality. Here, we choose Very Fast 1080p30.

Step 4. Choose the Container under Output Settings. MP4 is recommended for its broad compatibility. In addition, you can check Web Optimized which will compress your GoPro 2.7K/4K video using web standards.

Step 5. Tweak video audio parameters.
* Under Picture tab, you can cut down the width and height pixels.
* Move to Video tab, and then adjust video codec, frame rate, bit rate, etc.

Step 6. Click Start Encode in the top menu bar to begin compressing your 2.7K/4K GoPro video. Typically this can take a quite long time. One more thing, I received an error message "Queue Finished with 1 errors or cancellations detected" after hitting Start Encode button during my test.

Pros:
It's free to use.
It's safe to use, because of the absence of malicious stuff.

Cons:
HandBrake is a CPU-intensive tool always taking up more than 90% CPU power.
HandBrake is far slower than VideoProc.
HandBrake may fail to compress some 4K videos.
