Compress Large 4K/2.7K GoPro Videos [No Freezing/Crash]

"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."

Those super hi-def 2.7K/4K GoPro videos put heavy burdens on your storage devices, players, or other apps, making storage device running out of space quickly, playback failure, video recognition error on editing programs etc. Plus, it will take long to upload such large-sized video to YouTube and the like. All these demand a GoPro video compressor to reduce GoPro 2.7K/4K footages. In this article, we'd like to introduce you the best GoPro video compressor and how to shrink GoPro footages in various ways.

Winxvideo AI - Compress 4K/2.7K GoPro Video at GPU Acceleration

Processing 4K HEVC GoPro video is high-demanding on both software and hardware configurations (CPU, GPU, RAM...). How to smoothly downsize GoPro 4K/2.7K H265 video without half-crash or software freezing? A 4K video compressor with GPU hardware acceleration tech is the key! Winxvideo AI, with Intel QSV/AMD/Nvidia GPU hardware acceleration tech supported, can hand over the compute-intensive 4K HEVC video compressing task from CPU to graphics processing expert GPU.

Thus, the whole 4K x265 GoPro video shrinking process will be smoothly conducted, no CPU 95% overuse, CPU overheating or sudden crash/freezing troubles. Compress 1GB GoPro video to 368MB only at 320FPS compressing speed, 5X faster than any competitors.

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

What Winxvideo AI Can Do for You:

  • Compress GoPro 2.7K/4K to 1080P or other resolutions to make GoPro files smaller for fast YouTube/Facebook uploading, email sending.
  • Trim off unwanted segment to reduce the GoPro video length and crop out unnecessary image area to shrink GoPro video.
  • Convert GoPro 2.7K/4K video from H.264 to H.265/HEVC to compress video without quality loss.
  • Change bit rate, frame rate, sample rate and other parameters to lower file size.
  • Speed up video resizing process to 47x realtime faster by GPU HW acceleration while keeping a good balance between quality and size.

At the very beginning, free download Winxvideo AI to your computer and launch it. Now start your GoPro compressing journey within several clicks.

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

After launching Winxvideo AI, 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.

Step 2. Choose an output profile for resized 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.

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
choose output format

Step 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.

Step 4. Drag File Size Slider and Trim

Find and select the 'Compress' icon within the Toolbox positioned at the interface's bottom. Utilize the compression slider to easily diminish the video file size. On-screen, you'll view both the original and resulting file sizes, enabling you to efficiently reduce the video size while managing the compression ratio and output file size.

Trimming video clips before compression can help reduce the overall size of the video file. By removing unnecessary or unwanted segments, you can decrease the file size before applying compression.

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

Step 5. Begin compressing 2.7K/4K GoPro video.

Just click RUN button and the rest work will be handed over to Winxvideo AI. In addition to hardware acceleration, this program will also take advantage of MMX-SSE, Hyper-threading and AMD 3DNow! tech to quicken video resizing. Click to see more free video compressor software for help.

Part 2. How to Reduce 2.7K/4K GoPro Footage Size 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. It's free and safe to use, because of the absence of malicious stuff. HandBrake is a CPU-intensive tool always taking up more than 90% CPU power and is far slower than Winxvideo AI. It may fail to compress some 4K videos. 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.
