  1. Thanks for the information! I'll look into adapting GoPro Flip Close-Up Lens to Insta360 1 Inch. If it doesn't work, likely I'll just mount it next to the GoPro on the same tray - use GoPro for subjects within 90cm and use Insta360 1" for anything beyond. Insta360 1" + housing = US$630 and it is slightly wider than GoPro 8. Other 1" cameras that shoot 4K 60p + wide angle lens + housing = a lot bulkier, heavier, and far more expensive, which is why I'm interested in Insta360 1". My main goal is traveling as light as possible and still get decent 4K60p videos.
  2. Anyone has underwater experience with this Insta360 camera with an 1" sensor with 4K 60P option and a 60m (196.9ft) housing? I've seen a few YouTube videos, showing it has much better low-light performance under and above water than GoPros. Does it overheat inside the housing and how's the battery life?
  3. Extremely insulting! I'm reporting this to the moderator! Trying to help a fellow GoPro user now have to endure this type of behavior on this forum!
  4. Found this newer Flip Filter example! The magenta hue from the Deep filter can be easily corrected, shown below: GoPro + UW filter + color adjustment = results shown here at 31m (101')! Shooting RAW will get better performance for photos! GoPro users are smart enough to understand UW color dynamic and capable of making decisions whether this is good enough for them or not!
  5. Underwater light study done by University of Hawaii clearly stated that the RED SPECTRUMS are capable of reaching 40-meter depth in tropical water even though reds starts to appear dark at 20 meters, which is totally consistence with the fact that we can see with our own eyes in the 2013 Flip Filter video, some reds can be recovered at 27 meters (89 feet) by the 2012 GoPro Hero 3 with Dive and Deep filters even though the reds appear dark without filter. Photo and video editing software are all capable of restoring the recovered colors to how they should appear if the person knows how to use the software.
  6. These two 4K 60p video frames show 7 Black Protune Auto WB is much improved over the older models. Correcting colors for 10-meter (30-foot) videos should be pretty easy! However, using a filter below 8 meters (26 feet) is highly recommended!
  7. To those who are new to using UW filters with GoPro cameras, expect a filter rated 6-15m (20-50') to produce images a little red at 6m (20') and a little blue at 15m (50'). That's how filters and physics work! For deeper dives, it's a good idea to use lights! Speaking from personal experience, the 2018 Hero 7 Black with Flip Filters will produce better colors than what you see in the 2013 YouTube videos. I simply was unable to find a more recent example. Also, 7 Black RAW greatly enhances its abilities to take stills underwater.
  8. Magenta cast = a little more red than needed, also = Flip Deep filter will work at deeper depth than 27m, 89'. The magenta cast is SUPER EASY to correct in still and video! This image shows adjusting 2013 Hero 3+ Black video with FCPX!
  9. This video show Flip Filter performance at 27m, 89' with or without filters, and with or without lights. These tests were done with the 2012 Hero 3, 2018 Hero 7 Black has much improved underwater WB. My 2013 Hero 3+ Black with UW filters also produced similar magenta cast shown in this video; however, my 2018 Hero 7 Black delivers better colors.
  10. I recommend Flip Filters because they are easy to switch from no filter to Dive (6-15m, 20-50') to Deep (15+m, 50+'). I tried GoPro and Polar Pro filters and found putting them on and taking them off underwater to be a pain, and I had to bring a filter pouch. GoPro 7 Black takes RAW photos, which makes color adjustment easy.
  11. GoPro 7 Black provides option to use either HEVC H.265 or H.264 for many 1080, 2K, and 4K frame rates, but won't record H.264 at higher data rate to compensate for the codec shortcomings, resulting in lower quality videos! This YouTube video let you see for yourself (at 38sec mark) HEVC H.265 @ 320kbps outperforms H.264 @ 640kbps in overall image quality, especially in capturing motions. 7 Black HEVC H.265 videos can be viewed on the newer smartphones (iPhone XR was mistakenly omitted): https://gopro.com/help/articles/block/hevc
  12. White Balance: Underwater Auto WB for the 7 Black is much improved and I normally don't use filter down to 5 meters (16 feet). Beyond that, I recommend using a Flip Dive Filter since colors are harder to recover at deeper depths. Protune Auto WB is more stable than previous generations and color shifting is minimum. Sharpness: I leave it at "Medium" and never feel the need to sharpen 4K 60p clips any further. Also, 1/60 sec or faster shutters keep 4K 60p video frames from getting too soft since 60p videos don't need motion blur to look smooth. HEVC: 7 Black H.265 at 78 Mb/s can capture more details and better motion than H.264 at more than twice the data rate (156+ Mb/s), made possible by advanced codec engineering and much faster camera and computer processors! Example: bandwidth required for 4K broadcast: HEVC H.265 15 Mb/s vs H.264 32 Mb/s. All of the 4K 60p clips in this video were recorded with Protune above 10 meters (32 feet) without filter: https://youtu.be/Jc_NuFilVuU As usual, the YouTube version is much softer than the edited ProRes output.
  13. I shot a lot of 4K 60p videos with Protune on underwater - the most demanding settings on a 7 Black - and the camera never overheated. I only turned the camera on when I was ready to shoot BTW.
  14. Osmo Pocket waterproof case is not yet available. For sure I'll get one asap! UW White Balance: Forgot to mention 7 Black has much improved UW white balance for shallow depths around 6m (20'); therefore, Flip filters were installed on the camera but not used for recording my whale shark video .
  15. After using an Osmo Pocket and a Hero 7 Black extensively on a dive trip and a ski trip, in my opinion, these two small cameras are perfect complement to each other. Field of View: 7 Black is considerably wider. I use Hero 7 Black for super-wide shots, and Osmo Pocket for standard-wide situations. 4Kp60 Image Quality: Osmo Pocket captures slightly more details, but it's hard to tell during normal playback. 4Kp60 high-ISO Image Quality: Osmo Pocket has a lens that is one stop brighter and uses less aggressive noise reduction; therefore, it produces better IQ under low-light situations. Daytime Exposure: Hero 7 Black ProTune settings produce more accurate exposure than Osmo Pocket, which tends to overexpose by 1/3 to 1/2 stop, requiring manual compensations. Osmo Pocket's latest firmware adds a "Cine" profile and it does help the situation. I haven't tested it much yet! Stabilization: Osmo Pocket kept the horizon perfectly level and stable on the ski slope, and it was impossible to do the same with the 7 Black. Both cameras did a fantastic job, stabilizing the skiing videos overall, but, at the end of the day a real gimbal is better. https://youtu.be/Jc_NuFilVuU Here's my whale shark video, shot in 4Kp60 with a 7 Black, which was barely wide enough for the task, hence an Osmo Pocket would not be the right tool for this. However, a 7 Black was too wide for many small marine creatures and I wished I had the Osmo Pocket with me underwater. BTW, how do you get the YouTube link to display preview?
