HDV in Compressor
on Feb 1, 2011 at 2:27:14 am

Having trouble compressing a 57-minute film that was shot on HDV at 1080i 30F using a Canon XH-A1.

Here's a few versions that I've executed thus far using Compressor and/or straight from FCP:

Photo JPG --- 84.54GB
H.264 720p --- multiple versions ranging from 20GB to 1.76GB
H.264 640x360 (converted from H.264 720p version) --- 2.76GB

My goal is to get this file below 1GB and am willing to downres to SD.

...any suggestions? Should I try MPEG-Streamclip? I'm planning to upload to Vimeo and embed the film from there but I am open to other methods of presentation.

Thanks-

Back to 7th grade math.

A big 18 wheeler truck needs to travel 60 miles in one hour. How fast does it need to travel?
A tiny sports car needs to travel 60 miles in one hour. How fast does it need to travel?
The big truck and tiny car are driving at 60 miles per hour. Which one is going faster?

A 57 minute file needs to be 1GB in size. What data rate does it need to be?

kbits a second times duration in seconds is file size.
Convert kbits to MB or GB as needed.

Solve for X
2500 kbits a second x 57 minutes = X MBytes

If you're planning to upload to Vimeo - their guidelines are here

You'll have to pick h.264, and follow their rules. At 2000kb/s, you should get a file around 900 Megs - right around the size you need for Vimeo.

You'll need a Vimeo plus account, because I believe they limit you to 500 meg uploads.

Best,

Thanks Jeff- hadn't adjusted the kbps to 2000 for SD. That should solve things-
