Hi
I've been working on the edit of an independent film. we plan on screening the film at a theater played off of a Mac Pro. I've been having a problem outputting the final film and am confused.

How the heck do you properly output "720p 60f" footage????

Is it 960x720 or 1248x702???

My original footage was shot in HDVC 1248x702 HD, but when I import it into Final Cut it shows up as 960x720???? hunnh I'm really confused. Then no matter what, when I out put the footage no matter whether I output at 1248x702 or at 960x720, my film titles look pixelated. They DO NOT look super crisp and clear.

I'm confused on how to output the footage.

12" powerbook, Mac OS X (10.4.8)

    What type of video card (not graphics card) do you plan to use?

    Video card? as opposed to a graphics card? wow I'm stumped. I have a radeon xt-1900. But I believe that this is the Graphics card. WHy would I need a video card. I'm going to be sending the video to a projector via a DVI cable.

    Your codec and original image sizes make no sense - HDVC is not a codec & 1280x702 is not a standard frame size.

    What's up? What camera recorded the original material and what's the sequence preset settings for codec and frame size? fwiw - it sounds like you recorded using a Canon in one of it's wacky proprietary formats. Is this the case?

    Are you planning on playing out from the FCP timeline using Digital Cinema Preview or using a QT file and QT player?

    I'm with this guy. Yes, the dimensions don't work, but I shot a project in 720p 60 and now it's suddenly in 960 x 720? There's a big gap on either side of the viewer as I cut (conformed sequence) and I'm nervous, as I'm creating a lot of motion graphics for it and have no idea how they'll turn out.

    My scratch footage is at 1280x720.

    Any ideas? Is it 1280x720 or is it 960x720? If you know, would love to hear. Thanks!

    Your video was almost certainly shot at 960x720 or 1280x720.

    960x720 may be a pixel size, but it's not "square" pixels. If you're mixing new footage or effects, you should probably output at 1280x720, the square pixel resolution, using ProRes 422 for high quality, smooth playback. It's common for cameras to store only 75% of the horizontal resolution; HDV does 1440x1080 but it's always a widescreen image. Some 30fps flavours of DVCProHD use even stranger sizes, like 1280x1080, but the other size you mentioned sounds like a clean aperture or something similar — just use the full frame sizes in production.

    If you're seeing black bars left and right and a squished image in the middle, your footage needs to be reinterpreted. If the sequence is ProRes 422 1280x720 and the footage should match but doesn't, set Aspect Ratio property (in the Distort value in the Motion tab) to 0 and see if that works.

    A graphics card is a video card for these purposes. If you're playing back live from the Mac, make sure you're using 1280x720 with 60Hz as the refresh rate in the Displays pane of System Preferences.

    If your titles look pixelated, make sure that:

    a) Your sequence is ProRes
    b) You're not using bright red or green titles
    c) You have rendered everything
    d) You're viewing it at 100%

    Finally, make sure everything is rendered before playback and that nothing else is running or likely to pop up during the movie. You may wish to export the movie and play back with QuickTime Player or something else; if so, add plenty of black at the end.

    Hey Thanks for all the help.

    I have not posted back because I've been working like mad to try to get this thing done.

    Here are the details I left out. The footage was shot on a Panasonic HVX-200. There is also footage shot in mini-DV. If i "GET INFO" on a file from the finder. It says

    Dimensions: 960x720
    Codecs: DVCPRO HD (720p60), integer (little Endian)

    However and here is where some of my confusion lays. If I open the movie in Quicktme player, "show movie inspector" this is what it says:

    Format: DVCPRO HD (720p60), 960 x 720 (1248 x 702) Millions.


    ahhhh..... OK.... well which one is it? and correct me if I'm wrong. but "960x720" that's not what's refered to as 720p. Right?

    You're fine. 720p IS 960x720 in acquisition, but it's anamorphic. The size in parentheses is the display size. It's the same as shooting SD widescreen. You don't actually shoot 853x480. You shoot 720x480 anamorphic, and the display shows it as either 853x480, or 720x405. But the acquisition is still 720x480.

    If you are playing this from a Mac, it's simple. Export with current settings. Unless you have limited storage, don't even compress it. Export a self-contained Quicktime movie, and play that. If everything looks right in the timeline, it will look right on export. If for some reason it looks squished, open the movie, go into Window/Show Movie Properties, click on the video track, then the Visual Properties, deselect Preserve Aspect Ratio, and dial in the correct numbers. If it says 960x720, change the 960 to 1280.

    One last issue since you guys have been so helpful. for the past two months I have been working on a 5.1 surround sound mix for the film. It is done.

    Question: Do you know if that 5.1 audio file can be part of the same Quicktime file? then how would I play it "out" of the computer. In Soundtrack Pro and in Final Cut and Logic it is part of the sequencing program and interfaces with my MOTU 2408.

    Isn't there a way to use TOS link or something?

    You would need a surround sound card in your computer, or some external unit that connects to your computer. I don't know of any off hand, but your audio output jack is not 5.1 surround, it's 2 channel stereo. But the QT file can contain that information. You just need an output source.
