Thank you Lee, I know very useful. I purchased the RunCam Thumb that comes with Gyroflow. But I don't know how to use it. Thanks again for making this video.
Hi, I have a question. I have the iPhone 14 Pro Max. I'm not a professional, but I really like editing and recording videos (especially real estate videos). I want to use Gyroflow to stabilize some shots because even though I use a stabilizer (Hohem), I feel that in long shots, the walking is noticeable, and in the orbit-type shots, some movement is noticeable. How can I record the gyroscope movement? Because the iPhone doesn't give me the necessary data. I have an Insta360 X3 camera, does it help? In this case, would I need to set the same number of frames on both and the same resolution? But is there any issue when switching lenses on the iPhone (from normal to wide-angle)?
Lens profiles are selected once before rendering so you'd need to have lens profiles for all the settings. Ideally gyro data is needed to stabilise, but the latest versions have the option to stabilise footage without. See this page for iPhone docs.gyroflow.xyz/app/getting-started/supported-cameras/mobile-phones . Best of luck
A few notes: 1. Runcam gyro is not automatically synchronized, you need to click that autosync button, or add a few sync points manually. Only GoPro Hero 8 and later don't require syncing, all other supported cameras do. 2. When using Dynamic zooming, set FOV to 1. This way you'll have most pixels used and guaranteed no black borders. 3. For best results, and most cameras, you should use rolling shutter correction with a correct frame readout time
Thanks for the notes. I'm still testing the PRO here but the gyro appears pretty spot on.. I'll cover my findings in the PRO full 'review'.. happy flying!
Agreed Adrian. @ Painless, yes its very close, and it does appear to be working, but you see how the footage is still jittery. That means the sync may be off 1 or 2 frames (30ms-50ms) and the logging of the gyro data can drift over time so on a 2 minute clip the footage can be 4-8 frames out of sync. Autosync fixes all of this. Also, the recorded gyrodata is recording eveything at very high rates and so you really need to apply a low pass filter as well. Approximately the same as your video frame rate. So 60fps video maybe 60Hz LPF. I have a video on my channel about gyroflow.
it is possible, did it before with cheap HD cameras without gyros, but You have to get logging on Your FC about same time as You start recording, it makes easier to sync then, also You have to enter manually angle of Your recording camera and make custom lens profile, there were tutorials on RU-vid for sure for older versions of GyroFlow which will work with new GyroFlow as well ;)
Good video ! is it possible to use a supported action cam mounted on a dslr (only to record the gyro data) and then synchronize the camera footage with the stabilized action cam one?
@@Painless360 Thanks for your reply, very kind to take the time to respond. Is that mandatory to keep the same shutter speed on both camera (action/gyro cam and dslr) ? Thanks
every time i add a video file, gyroflow crashes and shuts down. i'm using the mobius maxi 4k and i've tried .mov and .mp4 formats and it keeps crashing. i've even tried with my runcam 5 orange and that crashes too. any ideas as to what could be causing this? i'm on the latest version of gyroflow at this time (1.1).
Lee, you mentioned using high resolution recording, because the stabilization process can discard a lot of the recorded scene. I would imagine you'd also want to "pull back" (or "zoom out") on the object(s) you are most interested in recording. Then, the parts that are discarded (I assume stuff on the perimeter) are less likely to contain the part you were really interested in. Is that correct? Also, the lense correction was dramatic. I'm thinking that's because a lot of cameras use fisheye lenses to give a wider field of view. Does Gyrofly essentially lop-off the wide field of view and discard it, and/or flatten the resulting video? Or once it's done stabilizing, does it put the fisheye effect back in? I'm intrigued by Gyrofly's ability to stabilize (clever tech) but it seems like it's changing the FOV and image depth dramatically. I'm wondering what you think about the video you're left with.
Lens distortion varies by camera and lens type, you can drop the amount of correction to retain more of the image. Flying at 200ft over trees needs very different settings than filming a desk as here. I may make some more in depth videos as there is a lot more interest in this video than I expected.... happy flying!
Higher resolution will help with the output, but no matter what the resolution, you will still feel like you are being cropped in and looking through a mail slot. Instead try to record in as much wide field of view that you camera supports and as much of the sensor as possible. For example, some cameras allow you to record 4:3 and then when you run gyroflow you crop it down to 16:9
Thanks for the comment, I've not seen that video but do agree that Gyroflow is not the silver bullet for everything and I've struggled sometimes here. It is improving all the time but we need to remember it is only V1.1.. happy flying!
