QT files are black
on Dec 12, 2008 at 3:13:24 pm

Clients can't watch my QT outputs on their computers. They get a black screen and audio.

Shot on Panasonic P2: 1080i/24p. Edited in FCP 6.0.5. QT files work fine on my Macs (Power PC G5 on OSX 10.4.11 with QT 7.5.5, Intel MacBook Pro on OSX 10.5.5 with QT 7.5.5, iBook on OSX 10.3.9 with QT 7.1.3)

Help!

Shane's Stock Answer #48 - See only black video, but hear audio, when try to open FCP captured QT files utilizing the DVCPRO HD, HDV or XDCAM codecs:

Unless the computer you are trying to open this footage on has FCP installed, they will not display video. These codec only comes with Final Cut Pro.

Or you can purchase the DVCPRO HD decoder from Calibrated Software:

Shane, Thanks for the prompt response.

How can I export these files quickly and with minimum compression (as close to raw footage) so that anyone can see them via QT?

Or can I re-save them (or re-export them) with QT?

Use Compressor. Choose a QT 7 setting...make sure that you make the dimensions 16:9 in the Inspector. Then drop in all the clips, drop the setting onto all the clips (save the setting as a custom one...that helps). Then let Compressor do all the rest.

http://www.imagineproducts.com is coming out soon with a product that wil automatically make low res proxies of your P2 cards when you offload them, complete with timecode. It will also automatically make low res proxies of anything that you import or capture. Just tell it what folder to look in, and when new QT files arrive, it compressed them in the background as new smaller QT files. In beta now, but due out very soon.

You can compress them to PhotoJPEG at 50 to 75%. They will play equally well on both Macs and PCs.

I'm not a big fan of PhotoJPEG- it's not efficient for the quality you get. I'd go H.264 which can play cross-platform and even ProRes- though it will tax a less than optimized system. Just make sure they update to the latest version of the QuickTime Player:

For once, you and I disagree Noah. PhotoJPEG will play lot easier on any system and the quality is decent enough for review copies and the processing time it takes to make them will be significantly shorter than h264.

Yeah you're probably right- it's just not the sexy latest technology. That's more my hang up.

[Noah Kadner] "That's more my hang up. "

That's hilarious. yes, PhotoJPEG is old, but it is very nice for review copies in a small form factor tht look good and totally cross platform. Also, it's 4:4:4 at 100%. Does that turn you on....maybe?

You're on a slippery slope trying to stay with the latest! The Adobe Media Encoder in CS4 makes some nice looking H.264 for Flash. What's your favorite encoder?
