DJI phantom 3 time lapse video, Sea of clouds in Clear Water Bay of Hong Kong.
updated 8 years ago
1. 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;
It is a project to test how to export particles with attributes (e.g. velocity, colors) to Blender.

- 16" propellers
- NCR18650GA 4S5P battery (16,500mAh)
- 4G data link by HUAWEI E3370
- Pixracer r15
- Raspberry Pi Zero with live streaming camera
- Insta360 One X (Camera)
- Parrot DISCO
- DISCO4G softmod (Thanks for active and friendly community uavpal.slack.com)
- Panasonic NCR18650B Li-ion 3S2P Battery
- HUAWEI E3372 (4G USB)
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 camera
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.
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.

The Insta360 with battery is weight 115g. I don't feel it has too much impact on Disco.

"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)
"Softwares for post-production"
- Adobe premiere 2018;
- GoPro VR plugin;
"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).

"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.

The result is not very well. I think Asia faces are not well recognizable because the training dataset is western faces.

山彦の滝 28米高的瀑布,隱藏在山林之中。航拍機在林頂往下望,完全看不見瀑布的踪影。在下面,人可以走進瀑布的背面,我稱之為3D的瀑布。
瀑布不算很大,但很別緻,經過丸瀬布的話可以一遊。停車場住山上走約五分鐘便到。

由於浪大,原來的行程「知床觀光船」被迫折返。在船上看到一個很有氣勢的斷崖,上岸後就在Google Map上找找有沒有陸路可以去到,原來就是知床八景之「フレペの滝」。
廣闊的觀景區內空無一人,腳下是百米斷崖,對望燈塔與藍天,真是一個航拍的絕景哦!
北海道航拍之旅第4天:
礼文島是我旅程中最期待的地方,美麗的自然風景,人不多,很適合航拍。但天氣不似預期,大風得連人也站不穩,航拍就更不用提了。
這條片是禮文島的東南端所拍的,地名是知床。那裡風還是很大,飛出去不知能不能回來。但太美了,冒險也得一試。正因為天氣不好,拍出來好有氣勢。
還是很喜歡禮文島,這裡我一定會再來的!I will be back!

オシンコシンの滝是很多香港旅行團都會「到此一遊」的景點。這天一早六點便出發到此,就是為了避免多人。在下面觀看雄偉的瀑布多了,今次有機會航拍一下,旅程又多了一點樂趣。
這個瀑布隱藏在樹林之中,飛行時要格外小心,萬一撞上了樹枝就玩完了。

好奇怪的,郵輪碼頭平台兩邊種了好些植物,使遊人不能接近欄杆。有些想和郵輪影相的人只有踩過植物,而管理公司就多加些警告牌,再加繩保護。為什麼變成這樣?上平台,想看看郵輪是常識的吧。 (哦,注意,此片不是在平台上拍的。)

這晚在雲丹御殿的夕陽晚宴,餐廳就是野塚展望台的景觀,望着太陽在ペシ岬的襯托下慢慢下沉,而且每秒鐘窗外都會有海鷗飛過,吃的是海膽大餐,這一個晚餐真的值千金。

這次我們特別繞了路,行稚內西海岸的沿海路,一路上都是濕原的延續,停車的地方是拔海附近。如果天氣好,對岸可以見到利尻富士,不過可惜今天視野很差,利尻富士只可略見形狀,不過沿途景色都不錯。

這次帶drone去旅行的旅程中,唯一一次有人「阻止」的飛行。
在飛行完結後,把航拍機拿回車上的不到50米的距離中,有位管理員女仕走出來,很有禮地對我說了一段日文,我估計是不可放航拍機之類的吧。我也有禮地對她說我現在就走了,她還向我說對不起,過程中沒有不快。
接下來的飛行我也盡量不在有管理的地方起飛,便沒有發生任何問題了。

神居古潭-北海道石狩川的溪谷上有條吊橋,這是一個賞櫻和賞楓的好地方,過了橋翻過小坡,便可見到廢棄了的舊火車站,外形是按照1901年開業時的樣貌來重建,留下來的鐵軌遺跡還上保存著3輛蒸汽火車呢。

在北海道旭川市附近的「北海道傳統美術工藝村」,由「優佳良織工藝館」、「雪之美術館」、「國際染織美術館」所組成。
其中雪之美術館最吸引,採用了拜占庭式建築,很有童話世界的感覺。它的螺旋階梯和冰之回廊,身在其中會聯想起「冰雪奇緣」FROZEN。館內的音樂廳感覺很寧靜,可能由於遊人不多的關係。還有一個結婚會場,可以想像在這處進行婚禮會十分華麗。

日本最大的黃色花海 - 北海瀧川油菜花祭 Canola flower in Takikawa
駕車進入滝川,便開始看到大大小小的油菜花田散布四處,只是會場的兩幅最大,花也最密。每年五月底至六月初油菜花盛開的日子,主場地每年都不同,要到時再上網查看。
