Resize from 1440x1080i to 1920x1080i
Good day,
Just would like to ask if there is any benefit in resizing 1440x1080i video footage to 1920x1080i? I can imagine that quality may be affected.
Also, is there any benefit in rendering Interlaced footage to Progressive?
Many thanks guys.

There will be no quality hit as both are the same size, just with a different PAR (Pixel Aspect Ratio). The former has a PAR of 1.333 while the latter has a PAR of 1.0
I regularly render my 1440×1080@60i projects to 1280×720@30p for YouTube use and don’t have any problems.

That’s great regarding the ‘no loss’ of quality. Can I trouble you for the best project and render settings to create a Bluray compliant mpge2 file?
I assume rendering from 1080i to 1080p is definitely the way to go. Would this be correct?
Thanks for your help with this Mike.

Sorry Michael but I’ve never made a Blu ray disk and don’t want to send you down the wrong path. This topic has been discussed at length on the Cow Vegas forum so I recommend searching there for the answers. Look for posts by John Rofrano as he answers this question a lot and knows what he’s talking about.

Actually Blu-ray wants interlaced video for NTSC and PAL and only allows progressive for NTSC 24p. If you are shooting HDV then I would use MainConcept MPEG-2 with Blu-ray 1440×1080-60i, 25 Mbps video stream template. This matches your source footage exactly. You could also use the Blu-ray 1920×1080-60i, 25 Mbps video stream template as well.
