Large AVI

I have several very large avi files (10g) that I need to turn into a 3 minutes time lapse of a construction project.  I've tried to render small pieces at a time to MP4 but I'm still having issues with performance and ending up with black screens.  I let one rendering go almost 2 weeks. I'm clipping large sections out of the avi and I'm speeding up the clips to 50X.   What are the resource hogs that I can avoid on the first pass while converting from avi to mp4.  I'm happy to put multiple mp4's together later.

how long in time are the AVIs; where did they come from

regardless, suggest you do multiple speed adjustment steps, maybe no more than 10x at a time

how much time would be between "frames" to go from real-time to your 3 minute goal?

maybe grabbing manual saved frames world work?

or play the AVI while recapturing with Recorder set to capture at 1 FPS

I would recommend the last suggestion, above.  It avoids potential data loss (or artifacts) resulting from from re-encoding multiple times.  It is also precise -- and simple because it is automatic.  Elegant.
