Video render size too large(Logitech c920) On exporting a captured video via Logitech c920 webcam , the size of a 1 minute clip is approximately 60Mb .Note that this is only a webcam capture and doesn't include a screen capture.I was planning a 4hr shoot ,but with such large render size,it would be very difficult. 

Render format -mp4 
Render settings - 30fps(Priority- FrameRate)
Openh264(Cisco)
Video-Hd1280x720 (7400kbps)
Audio-Stereo-48Mhz (194Kbps)
White balance-60%
Image adjustment -Turned Off
Antiflicker -60Hz

Is their any way to get a render with a reduced size ,without affecting the current quality and without using a postprocessing external compression software
60mb is already a ridiculously small size for a minute of footage. If you go even below that, your video will quickly look like one of those made with unregistered hypercam 3.0 back in 2009 youtube-era. Please don't. Hard-drives nowadays are incredibly cheap and I recommend just buying an external or internal one. You can get 1tb for about 50$. You could fit 16666 minutes of footage on there, which is over 277 hours. That sounds fair for 50 bucks. Please don't go below your bitrate, it's already barely intermediate.
