Canon 60d reduce video size

i recently shot a documentary with 60d & 5dmk2
total video data size is 300gb (it was 2-3 weeks shoot)

so now i wanted to ARCHIVE this Video Data But also want to Reduce its Size as in future it will be used for Re-Edits again...

Is there any Loseless Codec which can reduce the Video Data Size without reducing the video/audio quality?

I have only been working with ProRes files for the past several years and it doesn't do what you want, in fact it increases the file size by quite a bit. Just as a best practice I would suggest you save your camera raw video files PLUS any transcoded versions...yes we are again talking about taking up MORE storage space not less but the whole point is you want to preserve the best quality possible, not the smallest file size.

I don't recall what other lossless codecs do re file size, you could always create a one minute clip and then try saving it in different lossless formats to see what file sizes you end up with.

Generally what I do is export a ProRes version of the completed movie off my FCP timeline and save that as my master. I also like to save all the assets used to create the final version and sometimes all the assets period...ooops here I go again increasing your storage requirements! :-)

Also, don't forget about backups - how many you make is up to you but a lot of pros save the orignal files plus TWO copies - each copy stored on a different medium. LIke one backup copy on DVD data discs and another copy on a hard drive or online or something.

Do a google search for 3-2-1 backup strategy, I did it for you here:

https://www.google.com/search?q=3-2-1+backup+strategy&aq=f&oq=3-2-1+backup+...

I am told the top link from Dpbest flow is pretty good. This backup strategy comes comes from Peter Krogh's “The Dam Book: Digital Asset Management for Photographers”. ... Leo Laporte and Alex Lindsay from PixelCorps are always talking about it

The Lagarith video codec is a lossless codec that gives small files sizes (at least compared to others.

Check out this link http://bellunevideo.com/tutlist.php
"The Open Source Tool Kit" tut will have info on this codec.

@David Rehm thanks
but Lagarith Lossless Video Codec did preserve the video quality, but it also increaded my video file size from 135mb file to 1,225mb (1.2gb)

its a great video you linked to by the way

but, i need to reduce the file size & reserve the quality of video as well, even 5-10mb save on each file will do me wonders of disk space saving...
