If you want a native, uncompressed, or highly accurate export without conversion degradation, your project sequence must match the codec constraints directly. Can't export to file - Grass Valley Forums
If the steps above did not solve the issue, the problem may lie outside the standard settings:
The fastest way to bypass this error without altering your timeline is to allow EDIUS to convert the output stream dynamically. Press to open the Print to File exporter window.
The error “could not use the selected format” usually means one of the following: If you want a native, uncompressed, or highly
: This is the most common fix, especially for H.264 or H.265 exports. In the exporter dialog, untick the "Use Hardware Encoder" box (or select "Software" in the Encoder dropdown for newer versions).

If you have video I/O hardware (like Storm Mobile or Storm 3G), it may not support the specific format of your timeline, causing the error to appear when EDIUS tries to output a preview.
If you are exporting using an uncompressed or high-end professional codec regularly, your temporary render cache must mirror that level of quality.

The "Render Format" is the default codec EDIUS uses for temporary video rendering and for the final export. A mismatch here is the most common culprit. If the "Render Format" you've selected is incompatible with your chosen export format, EDIUS will stop you.
If your graphics card drivers are outdated or incompatible with the current version of EDIUS, the renderer can cause format errors.
