I bought in addition to the cameras GitUp 2P 90 and 170 for water and not only trips. You need to shoot only in the GoPro palette - thecomlors are very juicy. The Linear mode perfectly removes "pop-eyed". I tested it in different modes for about 30 minutes. During this time, the battery sat down by 50%, though it was in thecomld. Filmed in 4K + 60 fps mode, thecomputer refused to play, my hardware is clearly not for 4K. Image quality is many times better than GitUp. Hypersmooth is a real miracle, no additional electrical stabilizer is needed. I definitely recommend. I amcomrrecting the review based on the results of using it on a hike along the Lovozero tundra (Seydozero). The camera hung several times and started to get very hot. This was especially true when voicecomntrol was turned on. Only pulling out the battery helped. Several times during the shooting, in the middle of the video, she stopped writing the video stream, butcomntinued to write the sound. At the same time, she did not inform about it in any way, she found it only at home. The memory card is the fastest in tests, there are nocomplaints about it, I use it in another 4K video camera. All videos were shot in 2.7K 50 FPS HYPERSMOOTH, maximum bitrate. The quality is here (after auto-processing with youtube, the quality has deteriorated, but gives an idea): ? v=a7R_HdIQMts (colorcomrrection applied). The work of hypersmooth is excellent and is shown here (I hold the camera in my hands during the jumps of the motorboat on the waves at speed - a trip along Seydozero): ? t=920 Downgraded to 3 stars.
