How To Remove The Fisheye From Your GoPro Footage



You can easily tell if a video was shot on a GoPro by the extreme fisheye effect that is present in the video. The GoPro has an extremely wide-angle lens so it can capture a large field of view this is one of its selling points. Sometimes we don’t mind the fisheye look, in fact it can add to the scene, however there are times that the fisheye effect is a hindrance and we want to remove it. There are many ways to go about removing the fisheye from your GoPro videos Most of the big video editing suites come with lens correction tools. These big name editors are great however they can be very expensive and the learning curve is quite steep. This sometimes not the best solution for a casual GoPro user.

There is a simple solution provided from GoPro in its GoPro Studio editor and the best part is, its FREE! You can download GoPro studio from the GoPro website. In this tutorial I will show you how to quickly and easily remove the fisheye effect in your GoPro videos with a few simple steps.

How To Remove The Fisheye Effect in Your GoPro Videos

Step 1 – Launch GoPro Studio: To start off we will need to launch our GoPro Studio desktop app. When editing any video in GoPro studio we need to convert the GoPro video file first into a format that can be easily edited. It is in this step that we will be removing and fixing the fisheye effect.

Step 2 – Load Your Media: On the left hand side of the page click on the “Import New Files” button. Brows to the location of the GoPro video file that your would like to do some lens correcting on.


Step 3 – Set Your Conversion Parameters: We are going to set our conversion parameters by clicking on the “Advanced Settings” button at the bottom left hand side. Place a tick in the box labelled “Remove Fisheye”. Close the advance settings dialog box when done. At this point you can trim your video by using the cropping markers. Trim the beginning and end of the clip to get rid of unwanted sections. This will dramatically decrease the conversion time, especially if they are long clips. Processed to step 4 when complete.


Step 4 –  Convert Your Clip: At the bottom right of the screen we can now add our clip to the conversion list. Once done click on the “Convert All” button. Your clip will now be converted and the fisheye effect will be removed. The newly converted video file will automatically be saved to your default export location on your computer, for mine it is the “Videos” folder. You could just close GoPro Studio now as your new video with the fisheye effect removed has been saved to your computer. You can however go a step further to enhance your new clip. If you wish to enhance your video further proceed to step 5.


Step 5 – Enhance Your Video: To enhance your video file we can now bring this new clip into the GoPro Studio editor. We do this by click the “Step 2 Edit” at the top of GoPro Studio. When prompted open a blank template. You can now drag your clip to the editing time-line and do any enhancements you desire such as colour correcting, sharpening, zooming and speed changes.


Step 6 – Export Your Final Video:  So with all your video editing done we can now go ahead and export your final video. We do so by click on the “Export” button at the top of GoPro Studio. Set your export resolution parameters and click the export button. Choose a location on your computer were GoPro Studio should export the final video.

Please Note: Technically you now have 3 versions of the video on your computer. The original, the converted file that was created in step 4 and the new enhanced version. You can go ahead and delete the original and the temporary converted file or you may want to save them for archival purposes.

How To Use A Bluetooth Game Controller With Ryze Tello Drone



In this video I go over all the steps on how to connect, pair and use a Bluetooth game controller with the Ryze Tello drone. Ryze does not make a dedicated controller for the Tello, you can however use various game controllers to fly the Tello. These Bluetooth controllers for iOS are normally used to play games on you iPhone or iPad but they also work quite well to control some drones. Now one thing I would like to point out is that these Bluetooth controllers will not give you any extra range for your drone unlike other drones such as the DJI Spark. A Bluetooth controller is different in the fact that it does not connect directly to the drone. The controller connects to your iPhone and then the iPhone to the drone.

The controller I opted to go with is the Speedy controller by PXN. Setup is quick and easy and the controller has a nice quality build. What ever brand you go with make sure it comes with a phone mount. This is important so you can mount your phone while flying.

To set up your Bluetooth remote with your Tello Drone you will need to do the following steps.

  1. The first thing you need to do is power on and put your controller into pairing mode. You do so by long pressing the power button for 4 seconds until the battery lights start to blink slowly. Then press the “wireless” icon beside the lights to enter into pairing mode. The lights will now blink fast to signify it has entered pairing mode.
  2. Now you will need to pair the controller to your iPhone/iPad via Bluetooth. Open up the Bluetooth options in the settings app on your iPhone. Find the listing for the “Speedy Controller” or what ever brand you are using and click on connect. Your phone will now be paired with your Bluetooth controller. This step only needs to be done once.
  3. At this point you can connect the Tello drone to your iPhone via WiFi as you normally do.
  4. Launch the Tello app and that is it. The Tello app will automatically detect that there is a Bluetooth remote connected. You can go to the settings within the Tello app to view a diagram of what buttons can be used for shortcuts (see Below).

Using The DJI Mavic Air With DJI Racing Edition Goggles



In this video I go over the necessary steps that need to be taken in order to fly your DJI Mavic Air with the DJI Goggle Racing Edition. Before the two are compatible you must update the firmware on the DJI Goggles or you will not get a video feed. To update the firmware on your DJI Racing Edition Goggles simply download the DJI assistant version 2 from the listed location and follow the steps below.

How To Update Firmware On DJI Goggles Racing Edition

Once the DJI Assistant V2 software is installed, plug-in your goggles to a USB port on a desktop or laptop computer with the USB cable that came with your Racing Edition Goggles (same port as charging on goggles). With my computer I must have the goggles powered on and connected first before I launched the DJI Assistant or it will not recognize my goggles. This may not be the case for everyone. Once the DJI Assistant is launched you will notice your goggles listed, click on the goggles icon to detect and upgrade the firmware. You will see a list of available firmware versions. You must install the latest version for your DJI Mavic Air to be compatible with the DJI Racing Edition goggles. The update process will take about 3 to 5 minutes to complete. Once it has finished you are now ready to soar FPV style with your DJI Mavic Air.

How To Connect Mavic Air to DJI Goggles RE

One thing to note before connecting your Mavic Air to the DJI Goggles Racing Edition is that it only supports one display at a time (first one that is connected). The way I like to do it is to set up the Mavic Air and controller as if I was going to be flying with a smart phone display. Launch the DJI Go 4 app and connect to the Mavic Air. At this point you will now have the visual feed on your smart phone. Now Power on your goggles and wait for it to fully load. In the mean time unplug the mini USB connector from the side of the Mavic Air controller. Your video feed will now be lost on your phone. Using the micro USB cable that came with the DJI Goggles, plug the micro USB end into the goggles (Charging Port) and the USB-A end into the USB port on the bottom of the controller. At this point you should now have the video feed from the Mavic Air in your goggles. Your all set to fly. If there is no feed you may have to use the navigation on the goggles to set the correct input.

The reason why I like doing this extra step and connecting the phone first is that at any time during the flight if you want to view the feed on your phone again all you need to do is unplug the goggles and re-plug the micro USB cable back into the side of the controller. You will now have a normal feed back on your smart phone or iPad.
