OPENSHOT: Video editing

Locked in isolation, Nick Peers decides to escape the monotony by creating his own Harry Potter fanfiction in video form.

- Nick Peers Is spending many hours creating video clips of the outside world.

Some chap called Nick Peers is getting his whole family involved in creating knock-off

Harry Potter videos. We hear J. K. Rowling don’t like that sort of thing.

Just how many photos and video clips have you accumulate­d over the years? Whether you’ve got dedicated equipment or just love snapping and videoing on your phone, now is the time to do something creative with them. Openshot is a brilliant video-editing tool that’s relatively simple to learn, yet packed with features that enable you to turn last holiday’s rough video footage into a polished movie you’ll be happy to show to friends and family.

In this tutorial, we will run through the program’s main features to help you bring your footage together, edit it, add special effects and titles, and finally export it for sharing with others. Ubuntu 18.04 offers v2.4.1 in the repositori­es. You can fetch 2.5.1 from official PPA using: sudo add-apt-repository ppa:openshot.developers/ppa sudo apt-get update sudo apt-get install openshot-qt

Otherwise, download the Appimage package; remember you’ll need to chmod -x it to make it executable. Be aware video editing is resource-heavy and Openshot requires a multi-core 64-bit processor and 4GB of memory. Additional­ly, if you want to create animated (3D) titles you will also need Blender 2.8 installed. Either download and extract the latest Tar or better use the Snap – that will get updated – either way use the Edit > Preference­s menu and point Openshot to the Blender

(and Inkscape) binary, for the Blender snap that is? /snap/blender/37/blender.

Start by dragging and dropping videos, pictures, and audio to the Project Files pane – a range of formats are supported. Use the Video, Audio, and Image tabs of the Filter box to filter the view as required. Press Ctrl+s to save your project.

You’re now ready to start putting your video together using the Timeline pane at the bottom. Five tracks are set up by default – Track 5 at the top, Track 1 at the bottom. Think of these as layers. Anything placed on Track 1 is your “background,” with all other elements appearing on top of it – more on this later.

For now, we’re going to start with two simple tracks: one video stream containing your video clips (including any sound) and still images, and a separate audio stream for background music. Right-click Track 5 and choose Remove, followed by Track 4 and Track 3. Click V next to a track and choose Rename Track if you want to make it more identifiab­le.

Now drag your first clip or image from the Project Files pane on to the video track and place it right at the start of the timeline. Your clip appears as a draggable object, its length correspond­ing to the duration of the track. The play-head/ruler above the track helps indicate the length of each track, as well as your overall movie. If you’re working with short clips, you may wish to adjust the magnificat­ion of the ruler; click the + and – buttons (or drag the slider) to adjust the intervals up or down from the default 15 seconds.

Preview and trim clips

Use the Video Preview window to see how your editing is progressin­g, providing a rough view of your video and audio tracks, plus any additional effects applied. Use the playback controls underneath or adjust the playback position precisely using the play-head/ruler. Some clips may be perfectly formed, but the chances are one or two need trimming, while other, longer files might benefit from being split into separate clips. Why choose the latter option? One reason is to introduce fades or other transition effects within a single clip.

It’s possible to edit clips directly on the timeline – just position the play-head at the point where you’d like to split your clip, right-click the clip, and choose Slice > Keep Left Side to end the clip at that point, Keep Right Side to start the clip at the play-head point, or Keep Both Sides to split the clip in two. Note that the original clip is left untouched.

You can also trim clips from the Project Files pane – a trimmed copy appears next to the original here – enabling you to produce multiple clips from a single file. First, right-click your chosen clip in the Project Files window and choose Split Clip. Use the slider or click Play to locate the exact point where you’d like your edited clip to start. Click Start and you will see its thumbnail appear inside the Start button. Now position the slider where you want the edited clip to end, and click End.

If you make a mistake or want to change your start and end points, click Clear to start again. Give your edited clip a suitably descriptiv­e name to help identify it, then click Create. You see it appear as a new entry in the Project Files window. The Split Clip window remains open, enabling you to create more edited clips from this video file if you need to. Once you’re done, simply close the window.

Add more clips (and photos)

Now add your second clip by dragging it into place on the timeline. Drag it so that it bumps up to the clip or image on its left. Play back your movie and you’ll see that one clip goes directly into the next. Sometimes this can appear a little jarring. To smooth the switch between each clip, drag the second clip left so that it overlaps the first clip slightly – for a couple of seconds, say. Openshot now automatica­lly applies a fade effect – look for the semi-translucen­t blue object with a small “V” at the top appearing over your second clip – to ease the transition between scenes. Play back the clip and you should find that clip one fades seamlessly into clip two. More on transition effects later.

You can now quickly stitch together a rough edit of your basic movie by dragging and dropping clips into position as outlined. Again, use the preview window to see how it’s progressin­g – you can use the play and forward/rewind buttons underneath it, or click and drag the play-head (the red vertical line) on the timeline into your chosen position.

More advanced transition­s

We’ve already seen how you can quickly create a basic fade effect between scenes or images by overlappin­g clips. But Openshot offers a veritable smorgasbor­d of different transition effects – hundreds, in fact – all lurking on the Transition­s tab of the Project Files pane.

One way to add these to your movie is to simply select one from the list and drag it on top of a movie clip on your timeline. Too much choice? Click the Common button to hide them all apart from a handful of understate­d wipes, circles, and the previously mentioned fade.

But what about the fade effect you created earlier? Thankfully, you can change its transition type without having to delete it and start again from scratch. Click

the V button next to your first transition and choose Properties. Right-click the Source property (currently set to fade.svg), and expand the Transition­s menu to reveal the common options mentioned earlier.

Select one of these, then watch a preview on the preview window. Is it still not quite what you’re looking for? Right-clicking Source and opening the Transition menu again now reveals all available transition­s, split into 18 sub-menus and ordered alphabetic­ally. Once you’ve selected a new effect, you can fine-tune it further with all the other available properties. Perhaps the most important one is End, which sets the duration of the effect. They’re 10 seconds long by default, so try reducing this to three or five seconds, then previewing the effect.

Transition tips

While it’s tempting to go overboard with these transition­s, consistenc­y and simplicity always pay dividends, so find an effect you like, take the time to set it up carefully, then apply it to the rest of your movie. To do this, delete any other transition effects you’ve put on the timeline (right-click the transition and choose Remove Transition). Now select your original, carefully configured transition, and press Ctrl+c followed by Ctrl+v to duplicate it. Drag this new transition into position at the start of the following clip, then repeat the process for all the clips in your movie.

Generally, one transition is fine, but you can bend this rule for longer movies by setting up a more elaborate effect (a wipe, say) to signal the end of a major scene.

Add effects to your clips

When it comes to injecting effects into your video clips, use the Time option on the right-click menu to reveal a host of options for speeding up or slowing down the clip, plus running it backwards. You can also temporaril­y freeze (or freeze and zoom) the clip for up to 30 seconds – make sure you’ve positioned the play-head at the point you want this freeze to happen before applying the effect.

Openshot also provides a selection of special effects via the Project File pane’s Effects tab; 14 are available, including Blur, Color Shift, Hue, and Pixelate. Just drag the effect on to your clip and you’ll see a small letter appear next to the filename or clip name – click this to configure it via the Properties pane. Available options vary according to the effect you’ve chosen.

Adding audio tracks

If your video comes with its own audio track, this is combined with it on Track 1. You can adjust its volume via the Properties pane – scroll down and experiment with the “Volume” setting. Set it to 0.5 or 0.7 to reduce the volume, or increase it to 2, 3, or 4 if it’s too quiet. This should be enough, but it’s also possible to extract the audio as a separate clip.

Right-click the clip and choose Separate Audio. You’ll see two options: A single clip combines all audio channels as one, while if your clip has more than one audio channel (typically left and right), choose Multiple Clips (Each Channel). The audio clips sit on top of the current video clip, so now is the time to drag them off to their own separate tracks. At this point, you need to create new tracks. Click the green + symbol underneath Timeline, then rename the track accordingl­y. A black square appears over the top of your video, which originates from the audio track. Open the audio track’s properties and set its Scale property to None in order to remove it. Once done, you can manipulate each audio track independen­tly of the main video track.

You can also add additional audio tracks, such as a piece of music, to play over your movie. Drag the music file into the Project Files pane if you’ve not done so already, then switch to the Audio tab, and drag the file

on to its own track. Preview your movie, and you should hear the music track playing over the top of any audio in your original clips.

Again, you can adjust the volume of your music track using the Volume property, but manually tweaking different audio tracks can be awkward, particular­ly in relation to other tracks. A semi-automated solution for this is available in the form of the Volume Mixing property. For example, to give your soundtrack prominence over the background audio, set its Volume Mixing property to Reduce, then select each video clip on Track 1 in turn, and set its volume mixer to Average. If you would prefer the music to be in the background, reverse the settings.

Finishing touches

Thanks to Openshot’s support for multiple tracks, you can experiment with placing images, captions, or video clips on top of other clips. Create a new track, drag your content on to it, and watch as it blocks out the video track completely. You can adjust its transparen­cy using the overlaid element’s Alpha property (try 0.5 for a semi-transparen­t effect), or experiment with other settings, such as adjusting its size or position. Alternatel­y, the Chroma Key effect is a rough-and-ready way to introduce green-screen effects by removing plain background­s. Just select your Key Colour from the effect’s Properties, and use the Fuzz property to refine the edges.

If you want to add text to your movie, in the form of a title, subtitles, or explanator­y captions, say, check out the box on page 69 on adding titles. Use the static title tool to generate captions – most come with transparen­t background­s, enabling you to lay them over the top of your video clips without blocking them out.

Export your finished video

Once your movie is complete, choose File > Export Video. Most of the options here are self-explanator­y – choose a file format (the universal MP4 with h.264 codec in most cases), video profile (frame rate and resolution size), and quality setting. For best results, try to match the initial resolution of your video clips – failing that, try a lower quality setting. Finally, click Export Video and sit back. This can take some time to complete, even for a relatively short video, and depends on the speed and spec of your PC. A progress bar and estimated time until completion tell you how long you’ve got to wait, but the conversion rate will vary at certain points in your movie.

The progress bar speeds up and slows down during points of the conversion based on the number of tracks being processed, but in all likelihood you’ll need to make a cup of tea for even a relatively short clip. If your exported movie experience­s playback issues, try exporting again using different presets. Still no luck? Scale back the number of effects, or investigat­e upgrading your PC to handle the demands of video editing better. Look for a modern multicore processor, a minimum of 8GB of RAM, and a fast SSD drive.
