I have question? I have a green screen project finished. But when i render my footage to ProRes 4444 with aplha i got a mega file more then 5gb. In the specifications I found out that I have a bitrate of 203,57 Mbit/s. How can i lower the bitrate in the rendersettingd for this codec?
I hop to hear some of your suggestions.
You can't. ProRes codecs have fixed data rates.
What Andrew said.... Production codecs are all going to have high data rates. That's why we use them in production. Storage is so cheap now that it shouldn't be a problem for anyone that is making a living making movies or for anyone with enough budget to support a movie making hobby. My first 4GB Ultra SCSI drive array cost nearly $20K, I just bought a 1.5TB drive for $89... It wasn't that long ago that I was paying $1 / foot to shoot, process, work print and sync 35MM film. (98 feet / minute @ 24 fps).
If you want a smaller file size you'll have to go to a delivery codec. Just be sure you know what to use when...
