@@PeterChrzaszer-yx8fg Any problem?

@@osnbob4805 Yeah! Thanks

event the camera angle is fun and different

Thanks!

well i also have a gravel bike with mtb tires, but believe it or not that 80's steel roadie is faster and nimble than my carbon gravel in some regards, that's why the gears hack is such a plus

@@IsaacRC Yeah I know that feeling. I have a 90's mtb with cromoly steel, fast and light with 3x7 gears. It really made me a stronger rider.

@@cosmicwav yeah i was looking at some 90's mtb vids they where like actually kicking ass in todays standards without any suspension but also my back pain says thanks to todays 42tooth cheap cassettes 😅

Safety is of my first priority and I follow safety rules towards others from a bicycle stand point not from a motor vehicles point as they are in another completely different level of dangerousness, you can see in the video how i don't endanger anyone at anytime even more i lower speed and leave space or concede the pass when things get close. I don't say it's a model of riding, in fact this bike was faulty from factory- shitty mechanics is also a different story but explains a lot.

Thanks! Well after 18 years of uphills about time i learn to install big sprockets 😂 it's kinda weird industry won't cover that gear range? but now many people are sharing their hacks so it was a big support for me, hopefully i'm able to do it as well

Yeah in the city you can tell by the steepness of the street that the number of cyclist neighbours must approach to zero lol seriously i previously did a much better quality hack than this one with my 2x11 shimano grx gravel bike and without extender! but this 9 speed road bike it's much tough to crack, i really want to spread the info about this matter so i'm planning to do narrated nerdy bike checks but well my gravel bike it's been down since January, i think next week it will be up again so

Thanks! It was a gopro 9 + max lens + chest mount. Settings where flat color -2 exposure compensation, stabilisation normal and i think i used a particular audio mode for this model that works well: raw audio-non processed option (or something called like that) the fact is that it splits a wav file into 3 mono channels for each mic, the upside mic is the best for windy action, the bad thing is that's 32-bit that's raw unprocessed and i barely got it to sound good with my limited audio knowledge 😅

@IsaacRC thank you 🙏 Sick videos. Keep it up

I forgot to mention the lens mode and aspect ratio, it was like the default of in the Max lens mod option and also 2.7k in 4:3 ??? I don't remember but the fact is that later in video editor i used a sort of a plugin for Davinci Resolve called PTGui11 for correcting the curvilinear perspective into rectilinear and also to reframe the point of view, that's why the black bars up and down in the video, this way if the chest mount was looking down i could correct a little bit

@@javierorduna6914 appreciate it! I should mention that just a week ago insta360 launched its X4 model that pretty much makes all this complicated setup unnecessary, although Gopros still better in some regards, when it comes to cycling i would check the X4, the older models like the x3 has quality problems though

Thanks, i wish too but i'm keeping the gravel rest for a while, been bleeding money and time for 2 years plus, probably next month will be running again. Its a megamo gravel

@@IsaacRC That's awesome, I'm looking into gravels right now, was thinking about a road bike but the city I live in is stupidly hilly, so I'm still looking around, for now I'm just on a commuter e-bike and nothing more Well, hopefully your situation gets better soon, will be looking forward to see you riding around with it again 😁

@@igordomingues7870 Yeah this is very hilly too and full of fast traffic, while I'm doing mechanics just now, I can tell you that urban oriented bicycles have been in a kind of a dumb bubble for a while, as long as I can remember in fact, the first wall one hits is precisely with gear group-sets don't cover easy gears to go chilling steep uphills in combination with gears to pedal steep downhills, I use in this gravel bike a hacked Shimano groupset to cover these situations I could detail how you can do it. But even more important for me the brakes need to be strong which this hydraulic Shimano grx 600 is good enough, as third priority i would say the tire "wideness" capacity, now the bike has a 52mm-wide cheap mountain bike tires, as the MTB tire measurements are different than road I had to carve down the knobs because it was touching the frame (it depends on the actual wideness of the wheel mount and the capacity of the frame to make room) but for having stability and freedom of movement (obstacles, bad roads, rain, MTB, etc) i wouldn't look at any gravel that doesn't come with a 45c (45mm) minimum from stock which was the wheels that came with this Megamo bike. Now wheels are another whole discussion but the industry doesn't get much diverse either, but it connects with the final priority and no less important: the geometry, a gravel for me must be a fast and nimble bike, road bike geometry already is like that with a compact geometry but to fit bigger tires some modifications have to be done, so be careful with some trends that simply copy the long-wheel geometry from mountain bikes under the argument "it's a stable bike", unless you're planning on doing some kind of crazy "tokyo drift" on dirt roads that argument is BS rather I find an excuse to sell uncomfortable bikes to noobs hoping they will buy the next expensive model.

Thanks, I had to dig deep in UA-cam's audio library 😂

Thanks! I got lucky with the crash, could've gone worse

Thanks! It's the insta360 x3, i made it look good but normally it's not so good as reviews make it seem, actually i almost turned back the camera when i bought it, the new insta360 x4 probably is the solution to the x3 problems if you're planning to buy it

@@IsaacRC I'm actually having a hard time choosing between DJI Osmo aciton 4 and 360x4. insta360 x4 is very compatible for cycling and many things. But I also do street photography. and for that I need something single angle and smaller. Insta360 Go 3 also winks, but in general, I think Osmo Action 4 is the best choice. It also offers a wider range of color editing and night shooting. Thank you for your answer, I subscribed, I'm waiting for new videos ✨

@@ahakuytra5179 You're welcome, in my quest for a good action cam for cycling, I ended collecting 4 cams so far, I realised that when you ride there's some problems that standard action cams can't solve, mainly the fact that when you ride the torso moves in relation of how fast you are pedalling like when one is sprinting the camera ends up looking down ruining the vid, the only way to solve this is with a camera that can record 180 degrees (a fisheye lens) then in post one can always reframe, turns out a fisheye introduces many other advantages like if you noticed super wide field of views are more realistic with speed, looks actually as fast as it was, also better stabilisation as it has more image to crop. But for that a high resolution to crop is needed and that's where Insta360 X3 was failing with really bad compression artefacts but now with the x4 i'd guess they corrected that and can be the perfect cam for cycling, you can always crop as if it where a standard action cam, the insta360 software works perfect, and the raw photos with the X3 are perfect. Well there's plenty of secret tricks i learned with the x3 like using a single lens with Gyroflow, if you need tips feel free to ask anytime

yeah i disabled stabilization to get the full circular fisheye of Max lens, for technical reasons this mode is not supported for stabilising it in post with third party software, and honestly i don't remember if i used a DIY ND filter in between the gopro and the max lens but I think most probably i did

@@IsaacRC thanks for your response ❤️ Im currently working on my own mold for my gimbal and copy your setup. Once it is finished i will go to the phone app and speed up the panning to catch up with my downhill road cycling.

​@@Wtfitsgabonabike If you need tips for modelling the adapter or the problem with the max lens feel free to ask, I should mention the biggest problem with this setup is till this date Gopro doesn't support using the Max lens in full circular fisheye for post stabilisation with any of its models, I've tried with the 9 model like in this video and the 11 and it's not possible to obtain good quality stabilisation or "normal" stabilisation, the reasons are not a short story to explain, very technical, but also mention that I never asked directly to GoPro to solve for this problem, but if you wanted to ask GoPro please tell me because i would go and support your initiative if it's in the main forum

Insta360 x3

Well the POV is exactly as the thumbnail, I like it so much, perfect stabilisation, speed realism, easy to use, when did we need anything else for sharing?

Thanks, mountain riding at night during winter where past 6 is dark was a huge discovery for me

Thanks i also got an ahead adapter it fits ok but it's the stem diameter that I got wrong 😆 luckily i bought once a expensive Cinelli stem that came with a metal cilindre to fit normal ahead stems into thiner ahead fork tubes. I don't know today i tightened the nut but felt that the stem was still like percussing inside every time i brake with the front wheel, I might pushed the stem too far down perhaps (the stem tube shape gets thicker approaching the 90 degree bend) but this braking vibration started when I loosened the nut for sure very recently, i can't say yet it's 100% this what caused it because honestly it's a miracle this second hand road bike has stood cyclocross-like smashes for many years so will see, it would be really awesome to put it flying 60 + km/h, only thing is that i have to remember to not ride without hands as the ballbearings are totally crushed there's no free movement and more than once almost went down like a rookie 😆

Why the narrow bars?

@@MatthewBlue-yg1wkOh mainly because it's the only handlebars i found that where 100% straight without any weird bend for classic stem diameter (narrow) but also it comes handy for comfort as in urban riding one tends to stay mostly seated a closed angle of the arms helps with body stress etc

Noted BTW yesterday i posted a new video without music 👌

Normally I use thick plastic graduated sunglasses, never fall off they're very stiff, but with the normal glasses of thin metal mount is really a problem in summer with sweat they fall instantly so i made like a rubber band but then the nose mount like hurts a lot, dont know thick plastic mount all the way

Ima 170 so i could be wrong but taller sizes like yours benefits from the 700c wheel size standard, you see the frame sizes indeed change but they put the same wheel size so what i've seen is they push forward the seat post angle (from the bottom bracket) to make room for the wheels in smaller frames, rather i like the seat post balance of a bike to be as much over the rear wheel as possible so what i've seen is that big guys look for smaller sizes but then appears another problem that i recommend you to really watch out that is that the foot doesn't hit the front wheel when turning the handlebars that is kinda dangerous

@@IsaacRC Is Poseidon X Ambition good (Im on a budget so)

@@Huurhunmat Well yeah there's infinite details that matter but if you ask me I use every day bicycle with pretty steep uphills and dangerous heavy traffic so i've had really tuff moments with a bike so when I go to an elite bikeshop to buy they don't understand the needs as a matter of fact the whole industry itself is limited in some engineering aspects to my particular needs, so instead what i'd ask you, first of all, is what's your "ideal" expectations of your next purchase? What is your "ideal" use specifics you want your next bike to fulfil? And in order of priorities like: easy gears for steep uphills or a good looking but discreet design for urban areas etc From there we could translate in engineering language what actually you need and trickle down what boxes are checked or not amongst the product models on the market, that's why "ideal" is so important at the end of the day you can always improve your mechanics like installing better parts, i do it all the time, but the starting point, that is the bike model you decide to buy, will determine not only to fulfil your most important needs, after all the perfect bike doesn't exist, but also the capacity to adapt them or customise them in the future

It's for decorum 😁

Oooh you opened a can of problems friend 😂The short answer is: for this video I disabled internal stabilisation and used the 4K 4:3 in Wide (maximum field of view and resolution possible) also make sure Gopro Labs firmware is not installed then I used Gyroflow software to stabilise it, you will need to make a lens calibration for your max lens but since I already did if you want to test it I can upload it, here the problem starts that you will see small vibrations even when the main stabilisation is technically perfect with Gyroflow because with Gopro 9 is impossible to disable in-camera something called rolling shutter correction, GoPro corrects rolling shutter internally like it corrects stabilisation: it knows the movement of the camera and the lens geometry and corrects the rolling shutter distortion that sensors produce (that is the velocity that a sensor reads lines of pixels from top to bottom) BUT since we want the maximum field of view that is the Wide lens setting the Gopro "thinks" that the geometry of the lens that is has to correct is for Wide but in reality the geometry needed to be taken in account is for Max lens and there's no way of doing that, actually with the GoPro 10 and 11 you have an option using Gopro Labs firmware to disable internal rolling shutter correction altogether but then appears ANOTHER problem that is that the gyro data needed to correct for rolling shutter with Gyroflow software apparently is totally crap, almost unusable, curiously enough the GoPro 9 without the Labs firmware installed does good gyro data... it's like GoPro not wanting to make this possible perhaps? Who knows, anyway if any doubt ask freely BTW nice cycling videos you have bro subscribed! 👍

@@IsaacRC thanks! I used Gyroflow for the first time today. Could I give it a try with your 4k 4:3 Max Lens calibration file? Thank you for such a detailed response! You already helped me a lot with better understanding of where I should be looking. 🙏👍🙂

@@BrokenShifterCable You're welcome, by the way there's a Gyroflow discord forum with lots of info where Adrian (main Gyroflow developer) helps a ton with this kinds of challenges and I'm thinking that there might be a better solution casually only possible with the GP9, I will ask around in the forum but if it works I'll hit you back. Here's the lens profile link: drive.google.com/file/d/1KTHgLIiKLBTg5pMkuJSw4Ppg6fxrRO7F/view?usp=share_link

@@IsaacRC Thanks! I am testing your profile and it works great! I'll check the forums too, thank you!

@@BrokenShifterCable Forgot to correct the rolling shutter value in the lens profile file, the one that i passed you is wrong, I corrected it and uploaded it although the rolling shutter is kinda irrelevant since with the 9 it's already "wrongly" corrected from camera and Gyroflow shouldn't do anything so the best is just to uncheck the rolling shutter box option in the Gyroflow left menu, here's the link for the corrected profile: drive.google.com/file/d/1uRIbFGoHprgzkeAbYIYk6wKi0rIZqZjt/view?usp=share_link By the way whenever you want to know the rolling shutter value of any GoPro video (it varies depending on resolution settings like 4K, 2.7K, 4:3 etc) you can go to this web and upload the video file and instantly will show a list of data then you search for the "SROT" line and its corresponding value is the rolling shutter value of your video gopro.github.io/labs/control/metadata/

Thanks! I'm cooking a spicy one for this weekend, stay tuned for mad stuff 😆

Megamo gravel bike

This wasn't a LUT and also was recorded using native white balance, nevertheless amongst many color adjustments I used an experimental LUT for color saturation that is very powerful, so much that the more colorful colors go nuclear so with Davinci Resolve (or any software that can do that) you have to filter out the LUT to only affect the less colorful colors: drive.google.com/drive/folders/1SmKbeT7OyoyHlc57s3TfEr_VVp_Jaje2?usp=share_link

It would have to be a map of the size and shape of the water surface of the bathtub i guess

@@IsaacRC I ordered a camera to try and already picked up the larger fov lens. Thanks for your video it helped inspire me to work more on some of my optics projects

@@IsaacRC I’m going to try some with a few mirrors around it and try to see what the retroreflection will do and also use more layers of different refraction index if possible to see if 3 or more layers does something different or others

​@@angelarenee5832 Sounds good, experimental science in the visual field it's really fun, the last addition of my wish list is a glass prism for splitting the light or why not just a modern spectrometer. I should mention that both my Gopro models 9 and 11 came glitchy from factory, although the company is legit and very diligent on sending a fully functional replacement in a week, i would be prepared to beta test with a microscope those cameras for the first signs of software red flags and to document it for their online technical support, it's frustrating but they're in my opinion the best color science out there.

@@IsaacRC sometimes the mistakes can be useful. i had chromatic abberation in a cheap camera and helped me win an art contest lol. raman spectroscopy always fascinated me. i was supposed to train w a unit but the teacher was more busy w the quantum optics grant they had. i still hope to get a unit some day. good tips thanks.

Insta360 x3, a little fiddly to make it look good but for cycling field of view and stabilisation wise i'd recommend it over a standard action cam

@@IsaacRC yeah it really gives a nice wide pov. thanks for your videos ;)

Let's not disclose locations while I'm jumping red lights in YT 😄

No ND filters

@@IsaacRC how do you color grade video? It feels very gentle on eyes.

@@harisankar1317 I color grade a lot, Davinci Resolve is the tool i use, after making many adjustments i convert them into a single LUT, if you want to try I can post this LUT for download, but it will only look the same for this kind of scene (cloudy day, camera white balance, camera exposure, etc)

@@IsaacRC can you pls post the LUT

@@harisankar1317 Here's the download link, the 01 and 02 LUTs are almost the same but the 03 is darker used in the video for when I entered the forest canopy, remember it will only look as this video if the gopro is set to "flat" color, exposure compensation is 0 and the white balance in auto, also each model has its own color variations this was the 11 model: drive.google.com/drive/folders/1ilQF5Q8h4YK4wUZL_fWciIFhUccSee6G?usp=sharing
