MPEG4 AVC/H.264 Question

[Shane Ross]

1080i? 720P? 24fps? 30fps? 60fps?

Not that I know the answer, but those will help.

BUT… you don’t edit that format. That is not an editing format. You need to convert that to PRORES, and those numbers you can get by downloading the AJA DATA RATE CALCULATOR from https://www.aja.com.

GETTING ORGANIZED WITH FINAL CUT PRO DVD…don’t miss it.

Thanks Shane,

I’ll opt to shoot 720 30fps [that should make the file sizes smaller, right]?

I understand I’d need to transcode to Prores to edit the files, that’s not a problem – it was more about trying to figure out how large the shoot files will be so we can make copies [burned to DVD] to have Fedexed to me from overseas.

Thanks,

Wayne

Any figures will be approximate as H264 is variable bit rate so the content will help determine the file size. As Shane said, depending on the frame rate and pixel dimensions it will fall into a range of data rate per second.

All you need to do is multiply that average data rate by 60 to find out how much data per minute and then by 60 again to find out how much data per hour. If you have any info on the camera you can work it out.

Normally these cameras have a Data-rate selector.
The file size will depends of the quality you choose, whatever the frame size/time-base.
I saw that normally records between 18 and 24Mbps.
So you will get files smaller than with DV (25Mbps).
