Is this the lens? I will do some more research about lens options for the camera. I have the max lens mod but the gyro image stabilization seems fine without using it. https://www.skyreat.com/product/skyreat-1-33x-anamorphic-lens-compatible-with-gopro-hero-9/ https://www.amazon.com/Anamorphic-Compatible-Filmmakers-Cinematic-Accessories/dp/B093WD4CS1/ Thanks, Tom

Testing continues. I thought the Yi supported image stabilization at 4K but I was wrong. I will need to reshoot video at 1080p instead of 4K. The GoPro 10 continues to amaze me in video quality. I am impressed with the stabilization and dynamic range while heading into the sun with shadows from the trees. There is some curvature due to the wide angle lens that could be corrected by either shooting linear or shooting native sensor 4:3 AR and applying ReelSteady that corrects for wide angle lens distortion and crops to 16:9. Nice morning for a bike ride. Clear sky and cool weather. 4K/30 HEVC 44 Mbps Tom

Webb Captures Stellar Gymnastics in The Cartwheel Galaxy
tom95521 replied to Igor's topic in Slideshows & AV Shows
I have my doubts that humans will make the leap to an interstellar species. We have no propulsion technology that would allow us to travel fast enough for a human to visit another star system in one lifetime. That means our only option would be multi-generation space travel in a ship like Arthur C. Clarke's Rendezvous with Rama. Tom -
Webb Captures Stellar Gymnastics in The Cartwheel Galaxy
tom95521 replied to Igor's topic in Slideshows & AV Shows
It's hard to comprehend how large the universe is compared to our small part of a galaxy. I did a quick google search and a conservative estimate of 200 billion galaxies and each galaxy has an average of 100 million stars. Each star has an average of 2 planets. I think there is a good chance there is life and probably intelligent life far beyond our own intelligence. Thanks, Tom -
HI Rosy, I was thinking maybe cloud cover but where we live it hardly ever changes in summer. Overcast in the mornings, sometimes clearing up if there is enough wind in the afternoons. Our average summer temperature near the Pacific ocean is usually less than 70F/21C. If you want higher temperatures you have to travel inland a few miles to a higher elevation above the reflective cloud cover. I will try to make a proper 2 camera comparison in the near future so the same amount of light is on both cameras. Looking forward to viewing your video. Thanks, Tom

Short video. Still learning about GoPro editing. Unfortunately due to operator error (me) my Yi camera did not record when dual mounted with the GoPro so I used a previous Yi video from a few days before in the same area (notice the white truck in the upper left change). Also the cameras need to be tilted up higher. The GoPro records in HEVC at 45 Mbps and splits videos into 4 GB segments. The Yi records H.264 45 Mbps but not limited to 4 GB file size. Both cameras were set to 4K 24 fps. I think there are advantages to capturing at 24 fps like more light on the sensor and fewer frames to stabilize. The 4K quality out of the GoPro camera viewed on a 4K monitor is amazing. I re-encoded the video 2 times (GoPro player trim and PTE mask) and then uploaded to YT so there is some loss of detail in the video. The hypersmooth gyro stabilization does a very good job. The fine grain in the road is easier to see on the GoPro and the colors more saturated. I might do another video comparing GyroFlow, ReelSteady, FinalCut Pro, and Davinci Resolve stabilization software when I have time. I should also test the wide angle max lens mod for the GoPro. Tom

I was planning on using a PTE rectangular mask to split the screen. It should be more accurate for color comparison. Tom

Hi Rosy, I'm still learning the GoPro Quik app on my smartphone. I forgot to mention you could download the mp4 from the GoPro website (click on 3 dots in lower right corner). Here is the YT version that has the full 4K version. Also the media info. Thanks, Tom mediainfo.txt

Kind of busy but a short after dinner ride to test the new camera. I think the rattle sound is from the front LED light bouncing off the rack when going over a slight bump in the road. I will try to do a real road test and a dual camera test soon. The camera does get warm. The user interface has many more options than my Yi camera. From my limited testing I think the hypersmooth works better than the Yi image stabilization. Tom 4K 30 Hypersmooth High https://gopro.com/v/m0QDlGNBZbXLO

My GoPro and accessories arrived a couple of days ago. Busy with a room remodel so I just opened the box this morning. Missing the 64 GB microSD memory card (new card arrives on Tuesday). I also have a dual camera mount so I should be able to compare videos from both cameras. My bike is a hardtail (no rear shock absorbers). I have a couple of seats with seat posts. One of them has an elastomer shock absorber seat and linkage seat post suspension system (SunTour NCX). Tom

Hi Gary, That ride looks smooth. I will be testing the GoPro 10 soon. Thanks, Tom

I agree 100%. Igor and WnSoft provide the best support. I have been using computers for about 45 years and many operating systems and applications. To get replies directly from a programmer is amazing. Tom
-
Yes. I believe some of the items had a 30% discount . I'll send you a message with more info. Thanks, Tom

Yes. The GoPro Volta adds about 4 hours of recording time (if your memory card is large enough). Some people have had problems with the USB interface not working as a remote, with the bluetooth still working. It's supposed to be fixed with a firmware upgrade. https://gopro.com/en/us/shop/mounts-accessories/volta/APHGM-001-master.html Also the 155 deg. FOV max lens mod for maximum hypersmooth and level correction. https://gopro.com/en/us/shop/mounts-accessories/max-lens-mod/ADWAL-001.html Tom

I decided to order the GoPro. I wanted the option to overlay gauges like speed and elevation using GPMF data embedded in the video or imported from a data logger on my smartphone. Thanks, Tom
-
Hi Rosy, Good idea. I will do more research. I assumed the GoPro had the best stabilization, but maybe there is a less expensive option that has better stabilization than my existing camera. Thanks, Tom

I have a seldom used 2 year old Yi 4K action camera (GoPro clone). Recently started e-biking and thought I would try to capture video. I notice image stabilization problems on rough country roads. I am thinking of upgrading to a GoPro 10 and use hypersmooth or reelsteady to stabilize the video. Also I am upgrading my e-bike seat with suspension system that might help. Does anyone have a GoPro and have they created biking or hiking videos? How is your stabilization compared to the video below. Some of the YouTube videos look amazing but never sure if they give impartial reviews or payed influencers. Thanks, Tom Yi 1080p/30 Chest Mount

Goode idea. I like how Boxy handles history with slider or button or selection. Tom

If you want to try to chroma key the background then you could try using Google Chrome and press F12 to get into DevTools. Then you can adjust the background color by editing the html code. Remove app-bg and bg-image-full from <div class="app-bg bg-image-full bg-classic"></div>. Select a background-color from .bg-classic. I'm not sure about using a video alpha channel (limited to certain codecs) unless it's an animated gif. Thanks, Tom

I think the cloth animation algorithm is interesting. Amazing what javascript can do. If you want to make a quick flag in PTE just upload your image and then screen record a video. Many options to change wind, background, flagpole. https://github.com/krikienoid/flagwaver#readme Animate any image https://krikienoid.github.io/flagwaver/ Tom Demo

My results from comparing encode times using the very versatile Shutter Encoder software. I was surprised how much faster the AMD Ryzen was for AV1 encoding compared to the Mac Mini using Shutter Encoder. The H.264 encoding time is the same. The fastest encoding was 1 min 49 sec on the Mac mini M1 (almost real time) using Wondershare Filmora 10 or 11. AV1 is apparently not supported on the Windows version of Filmora. The new Intel AV1 GPU encoder is supposed to be 50x faster than CPU encoding. Tom Source video 1080p 33 Mb/s 1min 44sec 432 MB Output video converted to 5 Mb/s Mac Mini M1 SSD macOS 12.3.1 H.264 HW 33 sec 69 MB H.264 CPU 1 min 25 sec 69 MB AV1 CPU 16 min 39 sec 67.8 MB (11x slower than H.264 CPU, 30x slower than H.264 HW) AMD Ryzen 2700 SSD Nvidia 1660 Win 11 H.264 HW 27 sec 69 MB H.264 CPU 1 min 25 sec 69 MB AV1 CPU 3 min 8 sec 66 MB (2.2x slower than H.264 CPU, 7x slower than H.264 HW) Update: April 5 I am now getting faster than realtime encoding in the M1 version of Filmora 11. The Sample Project is 2 min 36 sec and the AV1 encoder is finished in 2 min 15 sec (>60 fps). When AV1 is added to PTE AV Studio I hope it works as fast. https://tommendenhall.com/pte/compare.html

From my limited testing AV1 software encoding is much slower than H.264/H.265. Now we are finally getting hardware encoding support for the open source AV1 codec. I hope AMD and ARM chips catch up with Intel. https://www.notebookcheck.net/Intel-ARC-GPUs-trump-AMD-and-Nvidia-with-hardware-AV1-codec-support-as-game-streaming-demo-vs-HEVC-shows.611051.0.html Tom

Future Windows personal computers will also have System On Chip (SoC) technology. It makes more sense to have a single large chip with shared cpu, memory, and graphics on a high speed backbone. My 2020 model M1 mac mini has been very fast and reliable. Tom

Hi Rosy, This brings back old memories. In the 1960s my older brother was a mechanic in a foreign auto repair shop. He owned a very cute little Austin Healey bugeye Sprite that he painted bright yellow. He then upgraded to the faster Austin Healey 3000 he painted bright red with electric shift overdrive and also a BSA 441 Victor dirt bike. The bike was single cylinder and it was a real thumper. I think it had a compression release to make it easier to kick start. Thanks, Tom
