I've been trying to find a middle ground for bit rate for a MPEG4 compression between the Medium VBR and High VBR setting.
I'm compressing a sequence from FCP 7 to Compressor 3.5.
When I compress using the Medium VBR bit rate the compressed video typically has a rate around 4.5 - 5 mbits/second. File size: 385mb
Compressing the same video using High VBR setting comes out around 20mbits/second. File size: 1.87 gb.
A huge difference is size and quality.
I need to find a middle ground. When I try to set the custom bit rate in the encoder pane I can only max out on just over 2mbits on the bit rate slider and it won't let me enter a specific above 2mb/sec in the bit rate field.
How can I get this video compressed using the MPEG4 setting to around 10mbits/second?
Don't use the 'quality' settings. Set the data rate by hand. Oh wait, you have. Yeah, Compressor is a pain for such stuff.
You can do this via a QuickTime Movie setting, go to settings and choose MPEG4 or h.264 (mpeg4, part 10) and have a QuickTime Movie that's in the mpeg 4 or h.264 codec at whatever data rate you want. Problem: it's technically a QuickTime MOVie.
Alternatively, you can create a true h.264 file by choosing any of the h.264 options (Apple devices, Blu-Ray and for DVDSP) and have more freedom with data rates.
