Since resource utilization is kind of a thing with me, I'm curiously 
watching this thread.  fullHD?  What does that mean in terms of 
resolution and frame rate, and D3200 native codec format?  What is the 
container format you are pulling from the camera?

Also, what happens if you render to a different format?  mjpeg?

does the memory bloat happen slowly as rendering proceeds?  is it a 
linear increase or does it happen after some amount of rendering frames?

common cinelerra transcoding/rendering uses ffmpeg/libavcodec as a 
backend.  I'd be curious if you see similar issue if you transcode your 
content directly, independently of cinelerra

ffmpeg -i source -vf scale=1280:720 -c:v x264 -r:v 29.97 -c:a aac -o out.mp4
