I've scoured the forums and the web, and have seen posts from some who have had issues with controlling their frame rates. However no solution has been found.

I am using make_video.py to convert a series of *.jpg files to one *.mpeg file. The params dictionary that is fed into vcodec.Encoder has frame rate keys,:

frame_rate_base
frame_rate
rate
base

but manipulating their values does not seem to decrease the speed of my mpeg.

After further experimentation, I achieved the result I wanted.

My frame rate was slowed only by changing the bitrate manually. I was hesitant to do this at first, because the mpeg1/2 bitrates were specifically defined, and I was not sure if changing their values would break their codecs.

I also was only able to change the frame rate when using mpeg1. mpeg2 would not change its frame rate.[/quote]
