3D Video Editing:
How to Create Your Own 3D Videos

As mentioned before, each 3D video consists of two videos, either recorded with two different cameras or a 3D camera with two lenses. Usually the recordings are located in two separate video files. However, there are some 3D cameras that only create one video file that contains both partial pictures.

First, load the 3D video footage into a new Movie Studio project:

• Open MAGIX Movie Studio Platinum and create a new project in the start dialog.
• You can access and drag the 3D video files into your project via the Media Pool. If you have two separate files, drag the first file onto track 1 and the second file below it onto track 2.

If the material was taken by a 3D camera, the videos are synchronized and you won't need to do anything else. If you have videos from two different recording devices, you may need to synchronize the videos first so that both recordings are aligned without any time offset. You should proceed as follows:

• By pressing the "S" (= solo) button at the very beginning, you can temporarily switch the preview to solo track 1, so that only this video can be seen. Otherwise, it will be covered by the video on track 2. This enables you to compare both 3D videos.
• Move the 3D videos within the tracks in such a way that the individual frames are exactly under each other without any time offset.

Select the synchronized 3D videos by dragging a rectangle over both objects with the mouse.

• In the Media Pool, open the Effects tab and click on the icon "Properties" in the effects category "Stereo3D".
• Open the "Create Stereo3D" dropdown menu and choose the appropriate setting for your videos. If you don't know which setting is correct, try the "Stereo3D pair (left image first)" option first.
• Put on your 3D glasses and switch the preview monitor to anaglyph mode. Click on the menu icon in the upper left corner of the preview monitor and select the "Anaglyph display" option.

The anaglyph display causes the two 3D videos to be blended and applies a red or cyan filter.

• If the picture does not look correct yet, try a different 3D setting from the Media Pool.
• If it's necessary to further optimize the 3D video image, use the "Alignment" effect dialog. This allows the possibility to adjust the two 3D videos spatially in order to improve the 3D effect.
• Use perspective correction in case the left and right 3D video image haven't been recorded in quite the right perspective in relation to each other in order to join them into a single, clear 3D image.

If the 3D video image is displayed correctly, play the 3D video and review the recording.

• Press the spacebar on your keyboard to play the video back. To stop the preview, simply press the space bar a second time.
• To jump to a specific position in the video, click in the timeline above the first track to move the playback marker. This also works during playback while it is "live".
• If you want to cut a specific section out of your 3D video, place the playback marker at the start and end points of the segment to be removed and press the T-key each time. This will place cuts in the object.
• To remove the unwanted parts from the video, click on the areas to be removed and press the Del key.
• A gap will appear in the track after removing the object. You can drag the following second part of the 3D videos forward until it connects with the first to fill this.

Now, you can edit your 3D video in a variety of ways and enhance it with additional material:

• If you want to create a music track, drag a music file from the Media Pool to any track below the 3D videos, e.g., onto track 3.
• For a voice-over commentary, activate an audio recording by clicking the red record button on the preview monitor. This will automatically play the 3D video, so you can see the video while adding your commentary.
• You can also apply effects from the Media Pool to 3D videos. You can use these to crop the frame or to add a virtual camera pan, for example.
• In the "Templates" tab, you can find title templates among other content. You may use all 2D title templates for your 3D videos, but there are also a number of 3D titles. After importing a title template, the "Title editing" will open.
• Browse in the other categories of the Media Pool as well, because almost everything you will find can also be used for 3D videos.

Lastly, export your 3D video as follows:

• To export a 3D video file, go to "File" > "Export movie" and select an export format in the sub-menu, for example an "MPEG4" (MP4). In the export dialog, you will find several options for Stereo3D video. The "side-by-side" options are for specific 3D capable playback devices. "Anaglyph" is usually the correct option and appropriate for playback on ordinary TV sets and computer monitors. Spectators will need standard red-cyan 3D glasses and will be able to enjoy the 3D video without any other requirements.
• To render the 3D video directly to your smartphone, upload it to a social media platform or burn it onto a disc via the Options in the upper right-hand corner of the program. Here, you will see a separate interface for burning discs as well as the dialog "Finish movie".
