Edit a video without the project file
The offer changed. The video still works. But all you have is the MP4. What now? Rebuild it into an editable Butter project, then work on the changes your next campaign needs.
Recreate a video when the project file is missing
When you only have the MP4, the job is to recreate the parts you need to change. Butter supports rebuilding an MP4 into an editable project: a new working version to develop. Start with a specific revision, such as a corrected headline or a new ending. A weekend promotion might need a different date; a product launch might need a clearer closing message. Bring that brief to the rebuild so the next version has a purpose.
How to rebuild an MP4 into an editable project
Choose the change
Start with your finished MP4 and one clear revision. Gather the correct wording and original assets you still have, such as the logo.
Rebuild the video
Use the MP4 as the starting point for a Butter rebuild. AI rebuilding uses credits. The result is a new editable project to review against your reference.
Inspect before editing
Check the part you need to change first. Inspect text, edges, overlapping elements and timing. Decide whether the reconstruction is a useful starting point.
Make the revision
Edit the resulting project, then play through the whole sequence. Check the surrounding scenes, especially the offer, closing message and reading time.
Change the text in a finished video
The promotion moved from Friday to Monday. Once the date is editable in your rebuilt project, retype it, adjust its placement and give the closing message more reading time. Manual editing lets you keep refining it: move, delete, retype, retime or resize. Those editor changes are free; AI generation and rebuilding use credits. Work through the approved copy changes in one project, with the campaign brief beside you and a clear list of what still needs attention.
How to change text in an MP4
Inspect the rebuilt text and other elements individually. If the headline you need to change remains part of an image, the job is not finished. Do not assume hidden artwork, exact fonts or complex effects have been recovered. Compare the new version with the reference at the moments that matter. Reconstruction is a route to a new working project, not a promise to recover the original source.
When rebuilding is the right approach
Ask for the original project first if it might still be available. Evaluate a rebuild when the finished video is what you have to work with.
| Decision | Original project available | Rebuild from an MP4 |
|---|---|---|
| Starting point | The existing editable source | A new Butter project based on the video |
| First action | Check the source contains what you need | Inspect the rebuilt elements before relying on them |
| Fidelity | Work from the original design | Compare the reconstruction with your reference |
| Best fit | Continue a project you can still access | Develop a new version when the source is missing |
Update an existing offer
Carry an existing ad into the next promotion. Make a revision list for the price, date and closing message so the new offer stays consistent from the opening scene to the end.
Take over a video handoff
Turn an MP4-only handoff into a concrete brief. Collect the approved copy and available brand assets, identify what must stay, and give the next editor a clear account of the requested changes.
What's under the hood
For designers, the important question is what the reconstructed project gives you to work with. Review element boundaries, text treatment and timing before polishing the composition. Look for differences in spacing, alignment and transitions. A visually similar frame does not prove that the next edit will be straightforward. Test the exact element or moment the brief depends on. If the original source becomes available, choose the starting point that best supports the remaining work.
Questions about editing a finished video
Butter can rebuild an MP4 into an editable project. Inspect whether the text you need is independently editable. Rebuilding creates a new working version; it does not recover the original source. Test the headline or word before committing to the rest of the revision.
