Don't know if you have time to cast your eyes over this Err 70 problem I keep getting.
Here is the crash report:

Here is the test code snippet:
for j = 1, clips do
msleep(1000)
movie.start()
for i = 0, 5, 1 do task.yield(1000) end
movie.stop()
task.yield(1000)
endThat is, I record for 5 sec and repeat until clips is achieved
Instead of movie.start() and movie.stop() maybe test key.press(KEY.REC). I find it more reliable, at least from early lua scripts I worked on.
Is task.yield(1000) same as msleep? Or is it pausing the loop until reaching 5, then continues? Anyway, msleep never failed on my end.
/my two pennies...
@Danne
Tried various combinations but continued to get the error and crash.
Have got round it by 'putting a man in the loop'.
Will up issue the script soon.
BTW the reason for the up issue is to get round the 128 frame TIFF average limit, ie take sets of clips of 120 frames each.

I have ffmpeg for mac working with tmix filter and 1000 files instead of 128. Are you able to compile for windows?
@Danne
No, I'm afraid I'm still not a compiler, 'just' a scripter ;)
I assume from what you say, tweaking ffmpeg to work beyond 128 was straightforward?
Yes. Change number 128 to 1000. Not too hard ;).
Compiling static build spanning from mac os 10.9 and onwards is harder.
Maybe some kind person will pick up on this and make that change next time MLV App is updated.
Thanks for all your help, as usual.

Been testing with masc. Not sure what is better though. Exporting multiple tiffs rather than one big fat averaged image. I tested a sequence of 269 files. Worked but not a fast workflow.
My 'use case' is to process as many images as there are in a single MLV, ie to an averaged TIFF.
If you and @masc could ensure the above is covered, as well as the other use cases, I will be a happy man ;)
Ensuring maybe not. Locally no problem to build and modify Mlv App. A more general solution might be hard. Right now only official ffmpeg builds are used so it means every machine needs some heavy ffmpeg compiling. See if anyone is interested in helping out.
@Danne
Understood.
As I say, hopefully those developing the MLV App for 'general use' will recognise the value of tweaking the tmix filter, eg to, say, 1000 ;-)
I'm part of the general use party. I suppose ;)
;) ;) :D
