- Export MP4 video.
- Save and load project files.
How to make a simple video edit in Grafiq
-
Open Video Tools.
In Grafiq, open More → Video Tools. -
Import video clips.
Use the import option to add one or more video files to the timeline. -
Select a clip on the timeline.
Click the clip bar in the timeline so the Inspector controls apply to the correct clip. -
Trim the clip.
Use Trim In and Trim Out, or drag the clip handles on the timeline. -
Move or reorder clips.
Drag clips along the timeline or reorder them as needed. -
Add audio if needed.
Import external audio for narration, music, or voiceover. -
Mute original audio if needed.
Use mute ranges when you want to silence part of a video clip under narration, music, or an overlay. -
Preview the project.
Use Quick Preview for a fast timing check, or Preview (HQ) for a higher-quality preview. -
Export the MP4.
Click Export and choose where to save the final video.
How to make a picture-in-picture video
Picture-in-picture places one video over another. This is useful for reaction videos, tutorials, demos, face-cam overlays, or showing a small supporting clip on top of a main video.
-
Add your main video.
Import the main video clip into the timeline. -
Choose an overlay video.
In the Overlay video section, use Choose Overlay… to pick the second video. -
Enable the overlay.
Turn on Enable overlay. -
Set the overlay timing.
Use Overlay start, Trim in, and Trim out to control when the overlay appears and what part of the overlay video is used. -
Choose the overlay shape.
Use Rectangle for normal picture-in-picture. Use Circle for a bubble or face-cam style overlay where supported. -
Set size and position.
Adjust Size, Margin, and Position to place the overlay in a corner or center. -
Set opacity if supported.
Adjust Opacity if you want the overlay to be semi-transparent. -
Click Apply.
Apply the Inspector changes before previewing or exporting. -
Preview and export.
Use Quick Preview first, then export the final MP4 when the timing and placement look right.
Rectangle overlay vs. circle bubble
- Rectangle overlay: Best for screen-over-screen demos, tutorial clips, picture-in-picture, or showing another video in a corner.
- Circle bubble: Best for face-cam or speaker-bubble style overlays where supported.
- Opacity: Useful for semi-transparent overlays where supported.
- Margin: Controls how far the overlay sits from the edge.
- Size: Controls how large the overlay appears compared with the output video.
How to add narration or external audio
-
Record or prepare your audio.
You can use a separate audio file such as a voice memo, narration track, music file, or exported recording. -
Import the audio.
In Video Tools, use Import Audio to add the audio file to the audio track. -
Line up the audio.
Drag the audio clip to align it with the video timing. -
Adjust volume.
Use volume controls to balance the video audio and external audio. -
Mute video audio if needed.
Add mute ranges to silence the original video audio where the narration or overlay should be heard clearly. -
Preview before exporting.
Use Quick Preview to check timing and audio balance.
Good uses for Video Tools
- Make a simple reaction-style video with picture-in-picture.
- Add a face-cam or speaker overlay where supported.
- Trim a video clip before sharing.
- Combine a few video clips into one MP4.
- Add narration or background audio.
- Mute part of a video under narration or music.
- Create quick tutorial clips.
- Rotate an output video if the source orientation is wrong.
- Preview and export a simple MP4 without opening a large video editor.
What to watch out for
- Video export re-encodes the file, so output quality, file size, and processing time can change.
- Large or long videos can take time to preview or export.
- Always click Apply after changing Inspector settings.
- If an overlay is not visible, confirm that Enable overlay is checked, a file is selected, and the overlay timing overlaps the main video.
- On Intel Macs, overlay support is opaque rectangle only. Do not rely on circle overlays or transparency there.
- Use Quick Preview before a long export to catch timing, audio, or overlay placement issues.
