One of the crucial aspects of making 360 degrees videos is video stitching. It refers to the process of combining the various video takes together with the overlapping fields to create a 360 degrees video in one screen. Stitching is mostly done through computer software and involves various processes dictated by the intended use of the video. Presented here are a few tips on how to stitch GoPro clips into a 360 videos.
1. Stitching GoPro clips into 360 videos step by step guide
Now that that you already have your raw clips and have also decided on the right stitching software to use, presented below are the post production steps you need to follow to arrive at your final 360 video-:
Step 1: Plug in the microSD card to the card reader
After mounting the card, you will notice that the file naming system adopted follows the structure of GoPro. Change this to reflect your own file structure for proper organization and the best way to do so is to create folders for each of the takes.
Step 2: Ensure that every clip is in proper order
Do a quality check to ensure that each clip is in proper order since a single missing clip will make the software not to sync all the clips properly and the final result will not be a perfect 360 video.
Step 3: Import the clips into the stitching software
Once done with the quality check, all the clips should be imported to the stitching software. If you are using Autopano for instance, all you have to do is drag and drop the clips in to the new project window.
Step 4: Sync all the video clips
Synchronize all the clips using audio and once this is done, hit “apply” so that you are ready to begin the actual stitching process. One beautiful thing about using this software for stitching videos is that it has up to 60 templates and with just a push of a button, all the clips will get stitched as they play.
Step 5: Adjust the Panoramic Stitching
At this moment, you have a nice panoramic view of the 360 degrees shoot. In general, it looks pretty, but a closer look will reveal some kind of messing between the stitches, such as lighting not matching between the cameras.
To iron out things, you will use Autopano Gig to smoothen out things and create the stitching you desire. For instance, you can use the vertical align tool to straighten horizontal lines which might appear wavy. You can also use the blending tool to harmonize the lighting between cameras so that the lighting is congruent throughout the video.
Step 6: Video Editing
After adjusting the stitching, you will be ready to export the video out of Autopano Video Pro. While rendering the video, (as exporting is referred to as in Autopano), you need to have the frame size as well as the frame rates in mind. The ideal measurements for the highest quality by this software should be 3840X1920 and 29.97fps respectively.
After rendering the video, open it in the editing software and for the purposes of explanation, we will be referring to Adobe Premier. At this point, you can start editing as you normally would for a 2D video. For instance, you can apply effects, color corrections, muzzle flashes etc just normally.
However, there are a few things you need to keep in mind while editing a 360 degree video. They are as follows-:
Be aware of the edge of the frame. For instance, if an effect or a title spills over to the edge, yo have to wrap it back together again.
In 360, YouTube videos will show you just a small portion of the sphere. Remember this when creating titles in the editing software. If the title is too large, it may extend past the field of view.
Preview the video in Color Eyes to ensure that the titles are of the correct size.
Remember to remove the rig where the camera was mounted. To do so, you can use Content Awareness tool in Photoshop or other third party applications such as SkyBox to get the same results.
Step 7: Export the Video
After you are through with the editing, the next step is to export the video and this should be done just as you would normally export a traditional video. While exporting, be sure not to forget the frame size, the frame rate and most importantly, you have to export the video as an MP4, which implies an H.264 codec.
Step 8: Upload the Video to YouTube
The video now should be ready for uploading to YouTube; however, you must first unlock it in the panoramic view and convert it into a sphere. You can do this by using a program known as 360 Video Metadata. Just have in mind that the video will initially process as a low-race panoramic view before turning into low-race spherical view and finally a high race spherical view.
With the software and the tips given above, stitching GoPro clips to 360 videos should be fairly simple and anyone who is interested in creating such videos can easily follow and make successful 360 degrees videos.
