confused with compressing mov and flv etc.
hi!
I have exported a movie from final cut as a mov file in size 2.46 GB and data rate 26.56 Mbit/s size 1920×1080
I now need to get it down to about 1 GB.
If I force final cut to set the datarate to 19 Mbit/s and changes the size to 1280 x 720 it will get down to a 1.9 Gb mov file.
I was thinking of if I might make it to a .flv instead and tried with sorenson squeeze at a friends place and exported as a flv instead but with 19 Mbit/s and 1280 x 720. Then it ended up at the same size as above 1.9 Gb.
That makes sense in some way cause its the same amount of data but my question is:
– Are there any point exporting to flv using sorenson or mov through quicktime conversion in FCP or are they just two different formats and havnt got anything to do with size and quality?
– if flv should be a better compressed format, what is a acceptable datarate to use?any other tip would be very much appreciated!

Hi Per,
A 1920×1080 picture has 2.073.600 pixels
A 1280×720 picture have 921.600.
That means basically half the number of pixels, so you can half the data rate (13.200Kbps) while keeping the same quality.
That would make a file of 1.2 GBs.
You can still reduce a bit the data rate to get the 1GB file and probably you won’t notice the difference.
Don’t use Flash. H264 is much better codec.

I agree – H264 in a Quicktime format (.mov) is the way to go. I wrote a detailed tutorial a short time ago about doing this in Compressor. You can read it here:
