rendering wrong resolution?
Doing something that should be relatively simple: Ripping a clip from a DVD, bringing it into FCP, scaling it up to 720p, exporting a Quicktime.
1. I’m ripping to ProRes 422 at the source resolution & frame rate. I start with a file that is 720×406 at 29.97 fps (although my dvd ripper insists on creating a 30fps file, I conformed it to 29.97 in Cinema Tools).
2. I import the file into FCP & drop it into a Sequence that is ProRes 422, 29.97, 1280×720. When it asks if I want to change my sequence settings to match the file, I say no. The file is then automatically scaled up to 177.xx%, to fit the 1280×720 raster, which is exactly what I want.
3. I Export a self-contained Quicktime movie using Current Settings. The file renders & gives me a movie which Quicktime Player tells me the actual size 1248×702.
Can someone explain the discrepancy? Is this a pixel aspect ratio thing?
Thank you!

1. “I start with a file that is 720×406” Where did that number come from? What are you using to rip Use MPEG Streamclip. It should be 720×480 anamorphic if the media is widescreen. Or better yet rip it directly to ProRes 1280×720.
2. is wrong because 1 is wrong. If you say No, who knows what you’re getting.
3. Anything is possible after 1 and 2.
All the best,

That’s the screen size on QT Player on display.
Import your file back to FC and read on the Browser the real picture size.

Yep, ok. That leads me to believe that my ripper isn’t being all it can (or should) be. I’m didn’t use MPEG Streamclip because (at least for me) I haven’t had a lot of (i.e. any) success using it to rip commercial DVDs which is what I’m using for this…nobody freak out, I’m just doing some tests for internal use only.
In the ripper than I’m using (the trial version of Foxreal Blu-ray Ripper for Mac), it gives me a 720×406 file when I use the “original resolution” setting. In related news, when I rip directly to 1280×720 as suggested (and already tried), I get a file that is 1272 x 720. It also gives me a 30fps file when I use “original frame rate”, which, as I mentioned before, I had to conform to 29.97 in Cinema Tools.
So, to paraphrase General Beringer from War Games: “After careful very consideration sir, I’ve come to the conclusion that [my DVD ripper] sucks”
In case anyone is wondering, I was trying to determine what gave me the best quality for an HD file…ripping the DVD at native resolution & scaling it up in FCP or ripping it at HD resolution & working with it that way. If anyone has any conventional wisdom on the subject, I’d love to hear it.

MPEGStreamclip is not a ripper. It can not skip the DVD protection.
MPEGStreamclip is to convert the files you get after ripping.[Hillary Knox] “In the ripper than I’m using (the trial version of Foxreal Blu-ray Ripper for Mac), it gives me a 720×406 file when I use the “original resolution” setting.

You can try the “Foxreal..” to do the ripping, the use MPEGstreamclip for the conversion.
Don’t check the “fps” button, so will keep the original time-base, and make sure to chose the size “Unscaled”.

I won’t put 2 + 2 together for you (on circumventing copy protection) but FairMount will let MPEG streamclip (or anything else) get to a decrypted DVD
