Sure thing, thanks.
In STP, I go to File, down and select Export
I name it, use a Custom Preset
Exported items: Master Mix
File Type: Using Compressor
Preserve Video/ Linear PCM Sterei 16Bit 48kHz
Preset: Custom template dialog box
Press Edit Presets
Drag the .mov file into the arrow box
Get Setttings tab, select GT H.264 codec
Destinations tab, select Desktop
After Export: None
Press Export
Then I wait some hours, a zip file arrives, and it won't open.
So far, that's all. thanks, Frank
