Export mistery! why an 1920x1080 come up stretched?
on Oct 12, 2012 at 11:20:46 am

Hi there,

I'm having this problem recently which I can't understand and drive me mad!

The 1920x1080 export from FCP comes up stretch!! as the SD anamorphic/non anamorphic issue but it's all in HD and it can't be possible!

If I play the export on VLC it does fix it but preview and quick time play it as an 1920x1080 sequence stretched!!
How is that possible?

I do have different raw file (but all HD or HDV)
1920x1080 apple pro ress
1920x1080 XDCAM EX 1080p25
1440x1080 HDV1080i50
few clip on 720x576 dvpal

Timeline setting
1440x1080 aspect ratio HD(1440x1080) 16:9
pixel aspect ratio HD (1440x1080)
field dominance None
frame 25
compressor apple pro res 422(HQ)


the export comes up in 1920x1080 but stretch.
what I'm doing wrong?!
here a snap shot with some info


thanks for your help!

Looks like you're exporting out a HDV sequence. HDV has a different PAR (pixel aspect ratio) then 1920x1080 HD and different from 720x576 PAL. That's probably why your stuff is looking stretched. The PAR is wrong, given that you setup your timeline as a HDV sequence.

I would recommend transcoding your footage to one common format. Either 1080HD or DVPAL depending on your output and needs.

Other options:
— Change your timeline settings to a standard 1920x1080, square pixel aspect. This will require you to readjust the HDV and PAL clips on your timeline (possibly scale them to fit).
— Change your export settings to do the conversion to 1080HD
