Does exporting frame from timeline is a sync process?

Hey, 

 

I'm bulding a PPro panel, I doing an export of a frame from a sequence using the command:

 

1. some line of code..

2. activeSequence.exportFrameJPEG(<timecode>, <path_to_export_frame>)
3. another line of code..
 
my question is - after this command is executed and the program moves to the next line of code (line 3), do I have a guarantee that the frame is aleady saved and the file is now ready for a read action?
 
I'm asking because I had some issues reading from that file right after I exported it, but when I used some delay (~400-500ms) before reading it, I noticed that I can read the file just fine.
 
thanks

Correct answer Bruce Bullis

Thanks again Bruce! (:

So I've manged to manually select a work area and it worked, but I can't find a propper way to set the work area from cod,e there's nothing online out there.

Is there a way to Get and Set the work area in Extendscript ?


PProPanel shows how:

No guarantees.

I can't find exportFrameJPEG on the documentation, is there a return value?

I'm trying to execute this method but nothing happens, no exception or other error as @dpt12 mentioned, the next line is executed right after. How can I resolve this issue?

The sequence is active, the time input is valid and also the file path.

Thanks.

exportFrameJPEG() is part of the unsupported, undocumented, and not-recommended QE DOM.

I can neither confirm nor deny that it returns a bool, true if successful. 😉

From my observation, exportFrameJPEG() consits of two parts:
- exporting frame, sync process.
- creating (writing) file, async process.

After export you still need to check if file was created in your system.
