Video encoder to compile Rhino rendered images

I am looking for a video editor/encoder that can compile the single images from Rhino’s /'360 degree turntable animation" into a format that I can save and send to somebody. MP4 preferably…the video encoder from Bongo is able to compile these, but the quality is substantially inferior to the HTML visual.

AND, if there is an appropriate software, am I able to test it first before purchasing?..I have had a couple bad experiences and would like to be able to test it for free

Try the open source ffmpeg (

ffmpeg -v quiet -stats -r 10 -i input -vcodec libx264 -pix_fmt yuv420p -crf 15 my_video.mp4

where -r 10 is the frame rate in fps
