The video engine seems to be compatible between 12 and 13, so you can use the v12 video engine without a problem in v13 as a workaround until Steinberg fixes this. I just imported a > 2 h movie file mp4 in 13 with the v12 engine, and it worked beautifully.
Here is how (I’m on Windows):
- Close Cubase. Open Windows Explorer.
- Go to C:\Program Files\Steinberg\Cubase 13\Components
- Rename videoengine.dll to videoengine.dll_13. Confirm the warning.
- Rename VideoCodec-Apple-ProRes.dll to VideoCodec-Apple-ProRes.dll_13. Confirm the warning.
- Go to C:\Program Files\Steinberg\Cubase 12\Components.
- Select videoengine.dll and VideoCodec-Apple-ProRes.dll.
- Right click and chose “Copy” symbol or hit STRG+C.
- Go to C:\Program Files\Steinberg\Cubase 13\Components.
- Right click into the empty space and chose “Paste” symbol or hit STRG+V.
Works beautifully here. Please don’t forget to undo this change before installing any further 13.x update, otherwise the existing files won’t be accepted by the updater and consequently won’t be updated. That’s why you made a backup in step 3+4. Just delete the copies from 12 and rename the backup files to their previous names to undo it.
Have fun
