1 hour video compressed size
« on: December 16, 2012, 11:20:34 AM »
Just wondering, but what size could a 1 hour video filmed using a 5d2 and a t2i at around 400 iso, 24p with magic lantern be compressed to using codecs available to the public exporting at 1080p that still retain enough quality to look professional?

What codec would you use?
What bitrate/settings would you use?

Either going to be editing using vegas pro 10 or premiere elements.

Needs to be a vimeo supported codec, and hopefully under 5gb.

Thanks guys

Check the Vimeo site for their recommended file sizes and bitrate settings. Then use your preferred editing software. I would suggest doing a trial run first experimenting with maybe a 1 minute clip. No sense encoding everything if you don't like the results. Post a link to your work when you're done.

In researching your answer I relied heavily on these links:

http://vimeo.com/help/compression
http://eugenia.queru.com/2007/11/09/exporting-with-vegas-for-vimeo-hd/

Basically, Vimeo is going to re-code your movie to VBR of about 2,500kbps average, 5,000kbps max. So all you have to do is to ensure that what you upload to them is comfortably above that.

Each 1Mbps of average bitrate is going to add 430MB to your file size. I suggest encoding at 5Mbps average (target) and 10Mbps max, for a final size of 2,150MB for one hour.

The best codec is known as H.264 and/or "MP4" and you want VBR so it should ask you for both an average (target) rate and a max rate. Main Concept seems to be the 'best', and also Sony MP4 AVC.

If you see a movie on Vimeo that seems to be better quality than yours, it could be that there's less movement; talking heads with bokeh don't take much data.

I just came to about the same conclusions as you, Andy, but what you got is much more detailed than what I was figuring! I just encoded 1 minute of film and multiplied it out and I ended up with about 2.2 gb for 1 hour when encoding MP4 @ 24 fps, two pass vbr with max set to 6,000,000 bps and average at 5,000,000 bps and AAC 48hz 128,000 bps audio.


I'm just going to be recording sunday church sermons, nothing fancy!

Thanks a ton for the help, guys.
