Resample is a button in Export > Advanced > Video that enables the Resolution, Aspect ratio, and Frames/sec fields.
This was added in version 24.09, but the concept of resample in export always existed in Shotcut. It is named “Resample” because it usually occurs after each frame of the Timeline or Playlist is rendered. Export = render + encode (uncompressed is formatting and writing).
Some sample uses for this feature:
- Video Mode resolution = source (can make editing interaction faster), AND you want to down-sample to make a smaller file.
- You composed this project at resolution X but I need Y, AND you have some stuff sensitive to size and position, AND you do not want to take the time to adjust these by changing Video Mode. Best quality is not a concern.
- You made this project at aspect ratio X but you want Y, AND you really do want black bars.
- You made this project at frame rate X but you want Y, AND Y < X.
- All your sources are <= Video Mode resolution, AND you are not using text or vector graphics, AND you want to upscale export in order to game YouTube’s encoding (or avoid some other upscaler such as in my TV).
In version 23.09 clicking this shows a dialog:
(“Reframe” in that dialog was a typo and should have been “Resample.”)
Click No to acknowledge that you really do not want to change the Video Mode at this time and resample the export.
In the next version 24.10 this button and dialog are removed and instead an inline warning message may appear that does not block anything:
