640 sd into 720 timeline
on Aug 24, 2012 at 1:46:58 pm

I'm having fits with this one. FCPX

I have a project using 640x480sd footage ripped from a dvd.
I need to use this footage with some newly created Motion graphics and create a new dvd.
I ripped the dvd successfully. I set my timeline properties at 720x480 nstc dv both plain and anamorphic.
Both version are wrong: anamorphic is appearing as 853x480 (although it says 720) and non anamorphic is appearing 640 (although it says 720 in the properties window).
I need 720x480 for the motion graphics and I need to either scale the 640 to fit (with a little crop) or in some cases stretch it to fit the 720x480.
I know the clips are taking a beating by upscaling and stretching but the client wants 720x480

Does anyone have any advice????

[Michael Denora] "I have a project using 640x480sd footage ripped from a dvd."
Ripping aDVD ou should be getting a 720x480 NTSC Pixels movie, whatever the DVD is 4x3 or 16x9.
If you've got 640x480, you have done something wrong when transcoding the files.
Convert the MPEG-2 again with MPGstreamclip making sure you check "720x480 Unscaled", otherwise you are unnecessarily making one downscaling + one upscaling.
You are working with a low quality format and you must avoid to lose two generations on the process.

Thanks Rafael you helped me last week with this issue.
I'm ripping using Protube imedia Converter software (seems pro) using a pro res 422 setting @ original size 640x480 (720 is not an option) (MPGstreamclip will not work with 10.8, the QT component is not compatible)
I then imported in fcpx and optimized media, then created a timeline ntsc 720x480 both anamorphic and not, expecting to see my 640 footage with two black bars on the sides. I thought from there I could upscale it to remove the black bars and either have a cropped image or transform it to fit.

The anaomrphic timeline appears 853x480 in fcpx window even though the properties setting read 720x480 and the non-anamorphic timeline appears 640x480 (without black side bars) even though the properties read 720x480

These values are correct when displaying NTSC as Squared pixels (PC screen).

How do I get a 720x480 final movie?

A bit more explanation: as weird as it may appear, FCP X is doing everything correctly because horizontal pixel sizes are different on different devices.

A 480p or 480i signal can be in the 4x3 aspect ratio:
640x480 (square pixels - ie computer screen)
720x480 (slightly thinner pixels - DV camera)

in 16x9 aspect ratio it is:
853x480 (square pixels - computer screen)
720x480 (anamorphic pixels, or wide pixels - DVD)

Weird ain't it? Once you get working that way it makes sense: Here is some more info: http://support.apple.com/kb/TA26788

Now FCP X will accept files with all these sizes (even thought the square pixel sizes are technically incorrect when working with video, but you can create files in that size just fine).

One gotcha with FCP X is that currently you can't manually tell a 720x480 clip to be anamorphic unless the clip is encoded that way. When you rip from a DVD most all of them don't embed the pixel aspect ratio in the clip, therefore you currently need a workaround. Just stretch the SD footage on the x axis 133%. (I've been waiting every release for a fix for this from Apple. It has to come soon!)

FCP X is going export SD when you Share > Export Media, as 720x480 with either an anamorphic or non-anamorphic flag set depending on the timeline settings. However when going to Apple devices it will export as the square pixel format, i.e. 640x480 or 853x480.

Does this make sense?

Thanks it's starting to make a little sense...... I think

I did just stretch the SD footage on the x axis 133% to fill the width.

But I can't seem to get a 720x480 screen in my fpcx window. It's either 853x480 or 640x480

What I need is a 720x480 proportion and then I'll stretch or crop and enlarge my 640x480 footage.

Can that be done?

Hi Michael,

FCP X is always going to show the corrected aspect ratio in the viewer. i.e. a 720x480 timeline or clip will "show" 640x480 (4x3) or 853x480 (16x9) in the viewer. If you choose Share > Export Media then it will export a 720x480 movie. If you open that movie in QuickTime Player you will notice that it is 720x480 but will in fact display 640x480 or 853x480 because of the aspect ration correction.

Is this making sense?

So are you saying there is no actual viewable in display 720x480

Yes that is correct. FCP X's viewer will always correct a 720x480 frame size (which is not square pixels) to display as 640x480 (which is square pixels). Internally FCP X is working at 720x480 but just displaying at 640x480. The export will of course be 720x480 if you do a Share > Export Media.

If your client wants 720x480 that is what they are asking for.

Michael,

By the way, you're best bet is to post in the FCP X Techniques forum rather than this one. This is the forum where people vent their frustrations with FCP X and the world in general. ;)
