How to export for projector
on Aug 26, 2013 at 3:12:27 pm

What is the best way to export a fcp 7 for screening via projector?

My sequence is DVCPRO HD 720p60.
Frame Size 960x720
Vid Rate 23.98.

During a test run the colors looked Washed out.

Also During a test run -- There were two thin black lines running running horizontal across the image dividing the screen into thirds. Do you think this is a projector issue?

Should I upsize it for better screening? If so to what?

This was my workflow:
Sent Sequence to Compressor:
H.264
Data Rate > 15,000
1280 x 720 -- I made the size larger. Should I have done this?
Pixel Aspect 1.000 Default for Size

Thanks

You base your export based on your playback device connected to the projector. You can attach a variety of playback devices to a projector. A video device will give you the best quality. Some devices can output an HD signal. AJA KiPro (ProRes), Blu-ray player (BD Disc), Apple TV (h.264)

You can use a computer via VGA or DVI. That will be your lowest quality.

[Julie Lewis] "H.264

That's OK.
Make sure that you set "Key-frames: AUTO".
In Compressor you must set the "Frame Control ON". and "Resize: Best".

Thanks Rafael,
Does everything else remain the same in Frame Controls? Do in need to de-interlace? I don't thing so because my project is DVCPRO HD 720p60. Rate conversion?
Thanks, Julie

[Julie Lewis] "Does everything else remain the same in Frame Controls? Do in need to de-interlace? I don't thing so because my project is DVCPRO HD 720p60."
Right.
Your stuff is already Progressive.


[Julie Lewis] " Rate conversion?"
Your footage is p60, but you said that your FC sequence was 23,98fps, so FC should have done the p60>p23,98 time base conversion.

Just to be clear... my sequence compressor settings is DVCPRO HD720p60 and the vid rate is 23.98.

I read on another forum that "video projectors don't do 23.98fps...they're clocked by the power, which is 60Hz so either 29.97 or 60p is best.".

So am I OK or should I change anything?

Thanks again,
J

That's if you are using an old NTSC projector.
23,98 fps is a a broadcast video standard.
But is to you to decide which frame rate you want to use.
There is a noticeable visual difference from 60fps to 23,98fps.
The picture at 60fps will be much smoother than at 23,98fps.
Picture at 23,98fps is film like; much more choppy.
