when using MuSymbol('export_utils.exportMarkedFrames')
to save the annotated frames, can we control the name, so that untill the annotated frames are being written we call them ending with .download
and once done strips the .downlaod
from filename ?

Hi @supercool,
Unfortunately, exportMarkedFrames does not support any sort of callback, however, if you check out the implementation for that function, it is fairly minimal, you could reimplement the changes you like in a new version of the function:
As of today, it looks like this:
246 \: exportMarkedFrames (ExternalProcess; string filepat, string conversion="defa ult")
247 {
248 use io;
249 osstream timestr;
250 let frames = markedFrames();
251
252 for_index (i; frames)
253 {
254 let f = frames[i];
255 if (i > 0) print(timestr, ",");
256 print(timestr, "%d" % f);
257 }
258
259 let temp = makeTempSession(conversion);
260
261 string[] args =
262 {
263 temp,
264 "-o", filepat,
265 "-t", string(timestr)
266 };
267
268 return rvio("Export Annotated Frames", args, removeSession(temp));
The remove session gets a callback, so that runs after the export is complete. If you build your function that does your post-export renaming, it would work well.
