Combining videos into one file is really a subset of building a compilation: you import the separate files as clips, let them get sequenced into scenes, and export a single MP4. The distinction from a full compilation build is that you're less concerned with hook/peak/payoff pacing and more concerned with just getting everything into one output.
Import every source file as a clip
Each separate video you want combined becomes one imported clip, up to 100 per project. Duplicate detection runs automatically on import via local fingerprinting, so if you accidentally drop the same file in twice it gets flagged rather than silently doubling your runtime.
Decide how much of each clip survives
Unlike a simple concatenation tool, ReelWorkshop's edit plans select and trim scenes from your clips rather than keeping every second of every file. If you specifically want full clips end to end with nothing dropped, trim each clip yourself to the exact range you want kept before generating a plan, and check the resulting plan to confirm none of your intended footage got left out.
Order matters
Reorder clips earlier or later so the combined result plays in the sequence you intend. The quality score assigned on import can suggest an order, but it's a suggestion, not a requirement — move clips manually if the combined narrative needs a specific order regardless of which clip scored highest.
Generate, preview, render
| Setting | Options |
|---|---|
| Target length | 60s / 75s / 90s |
| Resolution | 1080x1920 or 720x1280 |
| Audio | kept from source clips or muted |
| Container/codec | MP4, H.264 video + AAC audio |
Generate a plan at your target length, preview it live in the browser, and render. The render runs locally through WebAssembly FFmpeg and produces one MP4 that downloads to your device and appears on the Exports page.
Because the tool is built around edit plans made of trimmed scenes rather than a straight file-append, don't expect frame-for-frame preservation of every source clip in full. If you need an exact untouched merge of complete files, a dedicated concatenation tool is a better fit than an edit-plan-based compilation maker.
Common mistakes
- Assuming the combined output automatically includes every second of every clip — it doesn't unless you've trimmed to match and verified the plan.
- Not checking audio settings before rendering and ending up with muted output when you wanted the original sound.
- Picking 720x1280 out of habit when the platform you're posting to expects 1080x1920.
When to use something else
For a literal, untouched merge of full-length files with no scene selection at all, a plain video joiner or an editor's export-as-single-file feature will serve you better than an edit-plan tool.
