What does Video Transition Maker do?
Video Transition Maker joins two local clips with a real filter: crossfade, fade to black, wipe left or right, or slide left or right. Fade from black fades the first clip out and the second clip in, then plays them in sequence. It is not an abrupt cut. Overlapping transitions start at the offset you set. The output length is that offset plus the second clip. Fade from black does not overlap, so its output length is the sum of both clips. Both pictures are fit into one frame and set to 30 fps before the filter runs. Missing audio is filled with silence so the join stays aligned.

Browser and media limitations
- Only the listed transitions are available. The join is a real filter, not a cut.
- An overlapping transition discards the first clip's tail after the overlap ends.
- Both clips are scaled to one size and 30 fps, so the sources are re-encoded.
- A clip with no audio is padded with silence for the join. Very large files can exhaust memory.
How local processing works
Your media is processed locally in your browser and is not uploaded to Tubelexity for processing. The media engine downloads on first export. Page navigation and analytics still use network requests.
Frequently asked questions
How long is the exported video?
For an overlap, output duration is the transition offset plus the second clip. Fade from black adds the two durations because the clips do not overlap.
What if the clips differ in size or frame rate?
Both are fitted into one even frame, padded with your background color, and set to 30 fps before the transition.
Is fade to black just a cut?
No. Fade to black uses a through-black crossfade. Fade from black fades the first clip out and the second clip in.
Are the clips uploaded?
No. The join runs in this browser. The media engine downloads on first export.
