A practical guide to Join videos
Join Videos arranges several clips on a timeline, normalizes them to the first clip's frame size, 30 fps, stereo 48 kHz audio, and compatible intermediate codecs, then exports one program.
Example: combine three event clips chronologically
Order the arrival, presentation, and closing clips, preview every seam, and export one MP4 with consistent frame dimensions.
Task-specific steps
- 1
Add all clips, preview their orientation and sound, and remove accidental or duplicate files.
- 2
Arrange the timeline in narrative order and check the transition between every adjacent pair.
- 3
Choose common output settings, render the joined video, and verify duration, audio continuity, and orientation.
Options that affect the result
- Clip order defines the finished timeline from left to right.
- Scale-and-pad normalization preserves aspect ratio while matching the first clip's frame, and audio is resampled to stereo 48 kHz before concatenation.
Limitations to know first
- Joining does not add fades, transitions, color matching, or automatic loudness balancing.
- Mixed portrait and landscape inputs may need cropping, padding, or scaling to share one frame size.
Questions specific to this task
Why must unlike video clips be re-encoded before joining?
A continuous output stream needs compatible codec parameters, dimensions, time bases, and audio layouts. Re-encoding normalizes those differences.
Can joined clips keep their original resolutions?
A single conventional video track uses one output frame size, so mixed sources must be scaled, cropped, or padded.
