Stabilise Filter Example – Telstra Tower
On the left is the original footage from the DJI Naza F450 GoPro. On the right is the "stabilised" version. By uploading the original to YouTube, applying the stabilise, then downloading the MP4 and running it back through YouTube you're able to see a side by side comparison.
The stabilised filter has some funny side effects where it appears as though the video is suddenly zoomed in and out. The blurriness of the RHS probably isn't a fair representation because that side has been uploaded, compressed, and downloaded.
The process does crop the video slightly and uses the edges as a buffer to remove the sudden movements from side to side or up and down.
The videos are in pretty good time sync but you may notice the RHS looks like it's behind the LHS. This lag is due to the smoothing effect of the filter and sudden movements take a little bit more time to catch-up with the RHS.
I've since changed the mount that the GoPro uses and without any post-processing the video is quite smooth. It will be interesting to see how smooth a video would look from the new mount after applying the stabilise filter.
Overall for this type of video, the stabilise filter does a pretty good job.
Timelapse GoPro extended by external power source
Ran the GoPro from about 2pm till 8pm on the upstairs balcony. I'm not sure how long the GoPro battery would last so I hooked it up to a LiPO 2650mAh battery via a uBEC. I checked the charge before and after and it had used about 40% or about 1060mA. I think the GoPro battery is 1100mA so it would have been pretty close to dead flat.
A chilly weekend in Tat
Mum and Dad insisted I go outside to walk the dogs. Are they crazy!? It was freezing, wet and windy this weekend. Luckily my Great Aunty Chris gave me a nice warm body suit to keep me warm. I think I look a bit chubby in it though.
