What is the best compression for our purpose? July 23, 2009 04:00PM |
Hey Gang, thank you in advance. We tape our pastor's sermon on a canon xh a1, in HDV. We digitize to FCE. We create our graphics in CS2 at the proper size. Edit as needed. We export a reference movie. Open the reference movie in quicktime pro and save as HD264 (mpeg4). Play back on our HD projector comes right from a macbook pro (not the one we edit on) thru HDMI cable to the projector. Please Please, tell us if we have missed a quality step somewhere. Is there a better compression we can use? Thank you in advance for you knowledge and professionalism. 
What we are doing looks real nice, but want to make sure we're at the highest resolution.

Haven't worked on FCE yet, but I don't think Uncompressed HD or ProRes is available. With that set up, you would do good to capture and edit in AIC, or capture as HDV but render that out as AIC, then send that to Quicktime Pro for the encoding.
What bit rate/ frame size are you using for the encode?
Next, do you need H.264 in the first place? Can you playback AIC/HDV on the MBP? If so, you do not have to compress that down to H.264.

Within the same machine and a short time span, there's no difference in quality between a reference movie and a self contained quicktime movie. When playing it out on a different machine, a reference movie may not play at all.
A reference movie contains links to the source/render files. A self contained quicktime movie contains the video and everything needed to play.
Go AIC if you can, I recall Apple's white paper mention lower error rates on renders on AIC vs HDV.
Skip the H.264, if you can, if your playback machine is fast enough to play it back in real time, and you have sufficient hard disk space. You may need to have FCP/FCE installed to play back AIC/HDV, so do a check.
