Use a guided video to create keyframes in the stable diffusion; 2. Embed the stable diffusion keyframes with the guided video to EbSynth; 3. Combine the EbSynth exported videos on DaVinci Resolve with crossfade effect;Twelve Lakes in Shirakami-sanchi, Aomori, JapanBellergy RC2022-09-22 | A stock-video shared to pixabay.com for free download.explosion-experiments Houdini export to Blender for shading and renderingBellergy RC2022-01-27 | The abstract explosions were created on Houdini. It used the pyro solver to create a smoke simulation and then used "Pop Advect by volumes" to convert the smoke volume to particles. Finally, export the particles to Blender for shading and rendering. It is a project to test how to export particles with attributes (e.g. velocity, colors) to Blender.

The equipment used is as follows: - Parrot DISCO - DISCO4G softmod (Thanks for active and friendly community uavpal.slack.com) - Panasonic NCR18650B Li-ion 3S2P Battery - HUAWEI E3372 (4G USB)Disco4G 24km Long Range Flight with 3S2P Li-ion batteryBellergy RC2019-01-08 | This time, I tried 24km flight. It only used about 50% battery. Next time I can plan for a 40km flight.
I change the Disco's BATTERY_PERCENTAGE_TABLE_VOLTAGE in config file. It can provides more accurate li-ion battery usage data now.
This time I changed the 4G modem antenna angle, but the result was even worse. I lost connection 3 times on the flight. The reconnection took 1.5 to 2.5 minutes.
The Insta360 let me control the camera angle after flight. It is useful when i lost the signal.
The Parrot Disco installed: - Disco4G softmod - 3S2P NCR18650B Li-ion battery - HUAWEI E3372h modem - Insta360 One X cameraA little crash, but lost my Mavic 2Bellergy RC2018-12-29 | A very common mistake, I lost my Mavic 2 while on vacation. It crashed in the trees. The location was hard to reach. I searched it a hour but no result. I have to leave it because of travel schedule. The video is DJI Go app realtime cache, so the resolution is not high.Shoot 4K VR aerial video with Parrot Disco and Insta360 One X (long flight 6.7km)Bellergy RC2018-12-19 | I installed Insta360 One X on the bottom of Parrot Disco. It is the result of 4K VR video.
The soft stabilizer of Insta360 One X is awesome. The Parrot Disco swings in the air, but the picture is very stable. At the same time, you can see how hard the Parrot Disco works and it is very interesting.
In my other video, you can see how Insta360 is installed into Disco. youtu.be/5pgjx5-cwyY
The Insta360 with battery is weight 115g. I don't feel it has too much impact on Disco.

When I did this test, the effect was better than expected. Awesome!
"Shooting" I installed Insta360 One X on the bottom, just like many other multi-copter cameras. Now I can shoot a lot of angles that I could only get in an multi-copter cameras. Because it is a 360 degree panoramic video, I no need to distract the video angle and view during flight. Through post-production, I can find the angles I like in front of my computer.
Please pay attention to the screen (10:20), the eagle that rushed to the front was discovered when the post-production. Due to the speed, it is impossible to make a live capture.
"Disadvantage" 1. Insufficient resolution, this film is HD (1920x1080), we can't render it to 4K; 2. When the wind is strong, flying at high speed or climbing, the video will have a jello effect, which cannot be eliminated by post-production (00:33); 3. Post-production will take more time; 4. 360 video files are larger, and the computer's functional requirements are higher
"Landing" Since the camera is below, the Parrot Disco has no landing gear. A flat landing may damage the Insta360. So the place with the long grass is found to be landing, and the result is satisfactory. (12:07)
"Long distance flight" Thanks to the author of disco4g providing tools for long-distance flight for free. The video is taken from a single shot, from launch to landing, the longest distance is 6.7 kilometers (08:26). Source code: github.com/uavpal/disco4g
"360 video" With the same source file, I'm editing the VR video version, you can compare the source with the editing version, please stay tuned.FPV Racing Drone Build (timelapse)Bellergy RC2018-12-12 | It is not a guide of "How to build a FPV drone?", but I want to show you the full process that build from scratch in a timelapse video. If you didn't build your own racing drone, it gives you an overall idea that how it be builded.

They are 34-An-YuJin, 52-Choi-YeNa, 56-Lee-KaEun, 57-Huh-YoonJin, 74-Takahashi-Juri.
The result is not very well. I think Asia faces are not well recognizable because the training dataset is western faces.
