minor compression of movie without any qualityloss?
on Sep 14, 2010 at 9:06:19 pm

Hi!

I recorded and edited a shortfilm in final cut and will deliver it to a filmfestival through their uploading system in http://www.imdb.com. The problem is that my shortfilm is at 2.26 GB but the maximum filesize to upload in imdb is 2 GB.

so I have to get rid of 0.26 GB by compressing it someway. The file format at the moment is:

Ive been shooting it with a Canon HV30 with this format:

Frame size:
1440x1080

Vid Rate
25 fps

Compressor
HDV1080i50

Pixel Aspect:
HD (1440x1080)

Audio format
16-bit integer

Audio Rate
48 Khz


how shall I do this to preserve maximum quality?

shall I use:
- compressor?
- final cut and mixing with the export settings?
- final cut and quicktime conversion?

and in case of any above - WHICH SETTINGS?

thanks a lot !!!

Perik

There is no editing codec down from HDV. If you need to reduce size try H.264 1920x1080 at a really high bitrate.

But the real question is what do THEY want? Is it for the internet? Will they re-compress it?

Yes on the 1920x1080, the HDV 1440x is not a true size, software like FCP knows to play it back at 1920x, so when you convert it to H264 you would want to go to the correct size.

I would try 15 Mbps to start with. See how that looks to you.
