So I put together a video of Team Doublemints journey through the levels last night, it's about 18 minutes long total and set it to render... my normal settings are 1280x720 with a bitrate of 3000, mp3 audio at medium quality (112kbps I think). The file came out 425mb which is a tad large for what I want to upload.

So... I set it to render @ 640x360 (half size) and the rest of the settings the same... 425mb (down to the byte size they match!!)... I'm confused! Is the only way to get this file smaller to cut it's bitrate or did something go wonky?

Thanks,
