Now, whenever you open the project, as the cursor is on the problem clip, Resolve crashes the same way before you can interact with it, making it impossible to fix.
(I get it, 4x on a 4K clip is insane. but you should be able to change it back but you can't because of the crash).
4X scaling of a 4K clip gives you a 16K clip. Even 8K clips tend to give some people trouble, so I'm not at all surprised that this would cause problems. As my doctor always says: "if it hurts when you do that, then don't do it".
If you're desperate to get the project back, this is what I'd try (no guarantees of success, though):
- Create a small project with one clip
- Save the project
- Make a copy of the project and change the clip scaling
- Save the copy
- Use a comparison utility to see how the project files differ. This will help you find where in the project the scaling factor is set.
- Using that knowledge, make a backup of your original project file (just in case) and change the scaling factor.
Projects are stored in a database format, so you may need to use a database front end to make changes to it. Or, with a little luck, you may be able to use something like a hex editor to change one simple number from "4" to 2" or "1".
