My input comes from a hacked Nikon D3200 giving me FullHD, 64Mbit in h264. With only previewing these files I can already push towards the boundaries of my internal memory.
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
