350mb = 1,7gb!?
 
Hi,

I´m trying out Neoscene and I´m wondering if this file conversion is correct or if I did something wrong. I took this 2 minute 350mb AVCHD file from my NEX-5N and converted it with Neoscene to cineforms´ intermediate codec....I ended up with a monstrous 1,7GB file! Is this correct? Are the converted files supposed to be so massive?

Do these rough numbers make sense?
2 minutes / 350mb = 1,7GB
1 minute / 175mb = 850mb
10 minutes / 1,75gb = 8,5GB
60 minutes / 10,5GB = almost 1T!!!!

If very very easy to end up with 3 hours footage after a music video or a short. This would mean almost 3TB of HD plus a dedicate HD for the system.

That seems about right, yes. I reckon as a rule of thumb about 1GB per minute. But you should remember that this compares to roughly 8GB-10GB per minute for uncompressed HD. I do find that I buy a lot of 2TB hard drives ...

I think your calculation for the 60 minutes is a little off. The file size will be about 50GB.

Rafael,

Your math for 1 hour of converted video is way off. 60 minutes of video converted to Cineform should be only about 51GB. Three hours of video so converted should be just over 150GB.

I just looked at a recent 30 minute output file (Film Scan 1), and it's 28GB, so that makes 56GB/hr

You guys are right. I have to stop drinking before posting :)
