Mpeg 2 PAR Is Incorrect. HELP

BriceWilliams2 wrote on 12/28/2014, 11:37 PM

I lent out my backup cam for a 3 hour event that will go on to standard DVD.
I set up the cam (ax2000) to HQ SD Mpegp-2 and handed over the camera.

After the event I trimmed out a few things and wanted to send over the mpeg-2 files.
The photographer is a FCPX user, so I encoded with DVfilm DVCpro50.

VP13 render template: QT 3mps 1.21 PAR.
As the file is encoded and I watch the preview window, all is well.

When I view it on QT, it is 4:3 and the PAR is 1.0. I did check properties of QT and tried all the settings offered.

When I bring the DVCpro 50 encoded file back into VP13, the PAR is Square, the image is the same as QT player. After I change the media properties to 1.21, the preview is correct in VP13. So the encoding is getting something wrong.

Any ideas?
Here is a link to the file, forgive the quality, I did not attend the cam.

I just need to get Mpeg-2 files to work on FCPX or encode to something he can use. Is Streamclip a better option on his end? Or another format that will work?

Stock QT libraries in Vegas do not recognize anamorphic.
Will. Look at your clip in the morning.

QT won't play back this file for me "without other components". Then just takes me to a page with lots of 3rd party QT components. No clues as to what it needs.

Is there any reason why you can't send the original MPEG-2 files? The less conversion you do the better.

FCPX should also be able to open DV .avi files.

I was under the impression that FCPX cannot open Mpeg files without another component. The user of FCPX is more of an artist in photography than tech savy. The DV.avi looks bad on QT player, not sure how it will translate on his MAC.

I know DVfilm does a fantastic job in quality, just can't get the PAR issue straight. I also tried a few other formats like Cineform avi than export in QTPro, but the Cineform avi is also the wrong PAR.

The PAR is wrong in VLC player, so some kind of metadata is not working.

It seems the only format that get's it right is mainconcept mpeg; the template has a 16:9 option.

I am lost.

Two things:

1. Set 856x480 at 1:1 PAR, uncompressed MOV, "stretch to fill output". This will work. That's widescreen DAR, adjusted for mod 8.

--or--

2. Did you set 16:9 in the DVCPro template?
Seems to work here.

Will Try. I did use DVpro settings, just didn't get great results in quality.

Just tried Cineform AVI set to square pixels at 720 X 405.
QT displays correctly, files are huge but I can live with that.

Thanks again..anamorphic pixels in QT, as pointed out in this thread, is the problem.

I will never use mpeg format again for FCPX users, I will use my NX5U in 720p, it seems to down scale to DV well enough.

Avid LE 1:1X is another one to play with..
Must be installed on both machines.

Thanks for input musicvid10.

I purchased quicktime mpeg-2 component (mpeg showing 856 X 480 on inspector)
export as DVFilm DVCpro50 QT

Quicktime will now play DVCpro50 (Raylight) correctly, the inspector is showing 856 X 480.

FYI: if i encode directly from VP13 with 856 X 480 (DVCpro50 Raylight) I get a green column on right side taking up the space between square and widescreen: showing Square PAR video. Uncompressed, as you suggested, works great..just the 64gig for 10 minutes is hard to manage.

So for my $200.00...lend a camera, DVfilm software, component plugin, QT pro, many hours: a great lesson learned.

it was all worth it ;-] Many thanks.
