[1] Project Bin, Library: (Elaborate) (use links which is used in current handout)

The project bin is your media library. It stores all your video clips, audio files, and images for your project. You can import media from your computer and organize them with folders. The bin acts as a bridge, letting you drag and drop clips to the timeline for editing in the next step.

[2] Clip Monitor:

This is where the clip selected in the project bin is displayed. When you want to preview a clip before getting into the timeline, you can directly preview it from here.

[3] Project Monitor:

This is where the content of the timeline is being displayed with all the edits, effects and compositions applied in the tracks. It displays where your cursor is on the timeline.

[4] Timeline:

The most important section of the Kdenlive tool and most of the action/edit is taking place in the timeline. Here you put your sources in the order in which they will appear in the final video, make your edits (cuts and trimmings), apply effects, add compositions and transitions, and add audio and soundtracks. In the Editing section you will learn more about this using tracks and organizing your files

[5] Timeline Toolbar:

This is where you find all the editing related tools and features to edit your video project.

[6] Audio Mixer:

This section holds the audio mixing panel where you control the volume and pan of the various audio tracks and the master.

[7] Menu Bar/Toolbar:

At the top of the Kdnelive window screen you have access to the Kdnelive menu bar. The Workspace Layouts and the Main Toolbar.

Create new project

After launching Kdenlive, the first thing to do is create a new project. What is a project, then? A project keeps all the work on your video or slideshow. You can save the project and continue your work later, or restore your work if you need to edit something after you've finished it You are able to pick up where you left off once you save it as a project.

Image of choosing a new codec

Selecting a project setting, prompts a dialog box to show up on your screen when you select File > New > Project. There are several folders, and each folder contains multiple project options if you expand. The most important question at this point is: what settings should be selected? You can select 4K, HD 720P, Full HD 1080P, and many other resolutions based on your needs To put it another way, selecting 4K will cause your video to be rendered in its highest resolution, which calls for a more advanced hardware setup like only on specific smart 4K TV, High HD display computers and etc; selecting HD 720, on the other hand, will cause it to be rendered in its lowest resolution, making it suitable for usage with a less technical setup like basic smartphones, old computer, tabs. We can use FHD 1080p for learning and exploring; it is an intermediate resolution that is commonly used on YouTube, social media, television, and some movies. There are several project settings under FHD 1080p, Let's select HD 1080p 25 frames profile.

Importing your files to project Now that the project is ready, let’s start adding some clips into your project.

Click on the “Add Clip” icon, form file menu, directly it opens the file dialogue of your local folders, start browsing your local video clips, audio clips, images to start your edit.

Save the project

As soon as you finish importing your files and before starting any further editing, it is safe to save the project in your system's local folder, so you can resume the work you last saved. It is also recommended to store all the working folders in specific folders and subfolders that you are comfortable with. And make sure all the files are available in the main project root folder. it is also recommended that you save projects frequently.

Key Things To Consider 1.0

Folder Structure

Example image for folder structure

A well-defined folder structure is crucial for staying organized during video editing. It saves time, prevents frustration, and ensures a smooth workflow. Here's a breakdown of its benefits and recommended folders:

Benefits of creating Folder:

Easy file navigation: Quickly locate specific media files (video, audio, graphics) without sifting through everything.
Improved collaboration: Enables clear communication and efficient sharing of project files with others.
Reduced risk of losing files: Organized folders prevent accidental deletion or misplacement of essential project elements.

Recommended Folder Structure:

Main Project Folder: Create a folder with a clear and concise name reflecting the project title , this folder will house all the subfolders related to your video project.

Subfolders:

Project Files: Store your editing software project files (.kdenlive for Kdenlive,) here.
Assets: This folder holds all the media you'll use in your edit.
Footage: Unedited video clips captured from cameras or downloaded sources. You can further organize footage by scene, date, or camera operator for larger projects.
Audio: Background music, sound effects, voice-overs, and any other audio elements.
Graphics: Logos, titles, animations, overlays, and other visual elements.

Consider subfolders for different versions (drafts, final exports) for better clarity. Backup and Save Regularly: Create backups of your project folder on external drives to prevent data loss

About Tracks(to add content)

In video editing, a track is a virtual layer within the timeline where you arrange and edit your video and audio elements. Imagine the timeline as a multi-lane highway, and each track represents a lane for a specific type of media.

Video tracks[V1,V2]: These tracks hold your video clips, allowing you to sequence them and create the visual flow of your project. You can have multiple video tracks stacked on top of each other, enabling you to layer video clips and create composite shots.

Audio tracks[A1, A2]: Devoted to audio elements like music, sound effects, narration, and dialogue. By using multiple audio tracks, you can create a layered soundscape for your video

Lock: This feature in video editing acts like a safety switch for a specific track in your timeline. When you lock a track, you accidentally won't move, edit, or delete the clips on that track. This is helpful to prevent messing up important elements like music or narration while you focus on editing other parts of your video.

Video Layers: Each layer can hold video clips, images, text, or effects. You can arrange them on top of each other, letting you create effects, overlays, or composite scenes. By adjusting the order. Generally it goes as V1, V2, you can manually add as much tracks/layers as you want. Audio Layers: Each layer holds a different audio element, like music, narration, or sound effects. You can stack these layers to create a rich soundscape for your video, adjusting volume and timing for each layer independently, similar to video tracks it goes like A1, A2, etc

Audio Layers: Each layer holds a different audio element, like music, narration, or sound effects. You can stack these layers to create a rich soundscape for your video, adjusting volume and timing for each layer independently, similar to video tracks it goes like A1, A2, etc

Timestamp: A timestamp in video editing is like a bookmark. It marks a specific moment in your video timeline. you can click on them to jump right to that spot in the video. It's like fast-forwarding to the exact part they want to see.

Mute/Unmute Audio: As it says you can mute or unmute the entire track as per required.

Enable/Disable Video: As it says you can Enable/Disable Video the entire track as per required.

Note :The topmost content in the video layers will be displayed on the project monitor and the exact same thing will be rendered or exported.

Adding clips

Importing files into Kdenlive project

Now that the project is ready, let’s start adding some clips into your project. Click on the “Add Clip” icon, directly it opens the file dialogue, start browsing your local video clips, audio clips, images to start your edit.

Arranging files in tracks

After you have saved the project, the next step is adding files into the timeline and arranging it for editing. Timeline is the place where the media clips are edited. There are two different types of tracks, Video and Audio. Video tracks can contain any kind of clip for example Video, Images, graphic files and the text etc. audio tracks contain all kind of audios like music, track audio and sound effects. In both types of tracks, multiple tracks can be used by adding new track and per your requirement..

Files arranged on timeline

To add clips into Sequence select file from the project bin section and drag and drop it in the track where your files are suited.

Once a clip is dropped on a sequence, it can be moved (drag and drop it) to another place on the same track or onto another track.

Any time by pressing "space" button(or click on the “Play” button in the project monitor) to see the preview of edited work.

Before we move to next steps, these are some important tools used frequently while editing

Selection tool (Default shortcut S)

Lets begin the editing by starting with selection. As mentioned in the above image, select any of the clips that are on the timeline and start moving them by dragging left and right. You can also move the clip in track by dragging up and down. This helps you place the clip wherever you want as per requirements. When you have multiple clips on your timeline, you can also use this tool to join and separate clips

Razor tool (Default Shortcut X)

Using razor tool:

By using the razor tool, click on the cursor in the timeline at the point to be cut or trimmed, then select the razor tool by clicking on the toolbar or simply by clicking X (Default Shortcut Key). Click on the start point of the clip to have a first cut, and drag to the second or last point to have a second cut (on the same clip, multiple times can be used). Now select the portion using the selection key. Now that you have trimmed the clip, you can delete the clip by pressing the backspace/delete key or move the clip in the timeline using the selection key.

Ripple tool:

This tool is used when you have trimmed some of the portions on video or audio but you want it back or you want to extend it, or, in other words, it is used to shorten or extend the particular clip up to its full length. By default, a static image is added to the time limit of 5 seconds. If you want it shorter, you can cut it with a razor tool. What if you needed it for more than 5 seconds? Simply use the ripple tool to select at the end of the image; now you can drag it as much as you want, and Kdenlive has a special feature, which is that if you are in the selection tool or if you drag the cursor to any ends of the clip, the tool automatically gets switched.

Grouping and ungrouping audio

Grouping and ungrouping refer to two various forms, which are:

1.Audio and Video When you have imported any video file, it imports along with its respective audio , which are together called a group. If you separate both, it's called ungroup. Why is it used? When you need to remove the original audio from your video and replace it with another audio file or a background music, you can use this tool.

2.Sequence group In this case there are multiple audio and video clips in the timeline that are continuous can be grouped manually.

Why is it used? When you have to move a specific set of continuous files together if you group all, or if you can group all the files in the tracks with a specific duration, you can group them together and move them. This avoids selecting multiple clips every time.

How to Group and ungroup On your timeline select the video, right click on the timeline --> click Ungroup. Similarly, you can group an audio with video by selecting both and then right-clicking on any then click on Group.

Volume Control

Sound effect can be given for a video in Kdenlive in a very easy and efficient method.

To give the sound effect right click on timeline window that appears to the bottom of the screen click on "Insert an effect --> Volume (Key framable)". Immediately you can see a Red colored bubble on Audio timeline. You can flexibly move it to top and bottom to raise and down the volume respectively.

Resizing a clip

A clip can be resized from its start or end by dragging its left or right edge.

If you want a more precise resize, you can place the timeline cursor wherever you want the resize to end and use the menu "Timeline --> Resize Item Start or Timeline --> Resize" Item End.

Removing Space Between Clips

Right click in the space between the clips and choose "Remove Space".

Removing extra spaces between clips

Be aware however that if you have clips on multiple tracks in the timeline and they are not grouped, then removing space may disturb the alignment of the clips between the different tracks the space is only removed from the timeline where you clicked.

Key Things To Consider 2.0

Be aware however that if you have clips on multiple tracks in the timeline and they are not grouped, then removing space may disturb the alignment of the clips between the different tracks the space is only removed from the timeline where you clicked

Adding titles

Titles are text elements that can be added to the timeline and appear over the top of other clips. Titles are created in the Project Tree and then dragged to the timeline like other video clips.

To create a title, Click on Project > Add Title Clip from the toolbar

Here just start adding your title and do the formatting using different tools in it and finally click on “OK”. Once click on the OK, your title file will add to you project tree. Drag drop it on your track for adding into your video.

After inserting, check in your project bin for the title file and drag into your timeline

Inserting title to timeline form project bin

after dragging into your timeline it should look something like this.

If you want titles to overlay other footage, you put title clips on video track 1 and have the other footage on video track 2. You also need to retain the affine transition that is automatically added to the title clips if you want the footage visible underneath.

Inserting title over the video

Adding fade in fade out effect By adding fade-in and fade-out for the clips, it will smoothly change the slides from one to next.

Adding fade in/out for clip The most basic type of fade-in and fade-out are the fade from black and fade to black effects. The easiest way to add these to your media files is to move the mouse pointer close to the corner of a clip on the timeline, then click and drag until your fade reaches the desired length.

Adding transition effect

A transition effect in video editing smoothly bridges the gap between two separate clips. It creates a visual connection, adding flow and style to your video by:

*Animating the change: using fades,wipes,dissolves, or other visual effects to avoid an abrupt jump between clips.

*Enhancing the narrative: Emphasizing the passage of time, introducing new scenses, or creating a specific mood

How to add transition effect

Inserting transition effect

To add a transition effect, first 2 clips need to be placed next to each other without any void space. Double-click between the clips, and a basic wipe transition effect will be added. For another transition, click on the transition effect, which is in between the clips. A dilouge window opens next to the display window or project monitor. (Note: Place can be varied according to the customized workspace.In that dilouge box, there will be an option called wipe method. In that option, you can find different types of transition effects as per your requirements.

Save project files Kdenlive needs a project file to save the information that makes up a video project. Information such as the name and location of your project, video and audio files, timeline information, which clips have been trimmed, arranged, etc. This project file you can use it later if you need to do any change in your file.

Click on "File > Save Project", enter your file name and select location for save in that location.

Saving the project

difference between save and render project

Export/Render as Video

Once done with your all editing work, next is to export your video. This will convert your "Kdenlive" project into a single video file, which should play on any platform. to render Click on the "Project > Render" icon on the top toolbar. As soon as you click on render it shows multiple presets . In the beginning we have explained about Codecs and presets, based on that you have export/render the project. Here are the key things to keep in mind before exporting

1. When a variable bit rate profile is selected, the File Size section displays a drop-down for choosing the Video quality you want. 2. Select "mp4" format from the format list. 3. File size will differ from your parameter selection 4. In the last section, clicking on “full project” will render your entire project as video and by clicking on “Selected zone” will render the portion you are selected.

Notes: while exporting/rendering project we can render the entire project or a particular part.

Exporting in particular part

Selecting particular portion

In the above image, just right above the timeline, you can see a blue slider. By dragging the edge of the bar, you can choose how much sequence or portion you need to export. After selecting the portion, click on Project > Render. In the lower middle of the dialogue box, there will be options called 'Entire project' and'selected zone'. You have to select'selected zone' to export a specific portion of the project

Entire Project

If you want to render/export the entire project select entire project option before rending (Note: this will render the entire project including the blanks if any blanks are present)

Which Preset is best to use and why?

In the menu render option, you will find multiple render options. The MP4-H254/AAC preset is best because it exports in a standard preset, which is most commonly used in web videos like YouTube and social media platforms. and supports all devices, like smartphones, computers, and televisions.
