1920×1080 vs 1440×1080
All,
Sorry, this may be redo but this forum is more active than the HDV one.
Would some please help me understand what format to record? 1920×1080 vs 1440×1080? 60i vs 30p? I prepare to edit from premier pro out to H.264 format mp4 (keeps at 1080p) BTW, what file size should I expect out of these? Are both 1920×1080 & 1440×1080 true 1080p? What is the regular HDTV support? 1920 or 1440? May be I am just confused.Sincerely,
Perry -

Had me confused for some time too. I think I’ve cracked it…
HDV = 1440 which is 16:9 anamorphic with a PAR of 1.333
HD – 1920 which is square pixel PAR 130p = progressive
60i = interleavedIf I’m doing a mixed edit using HDV footage (Sony Z1) and HD EXCAM material (Sony PMWV350), I uprez the HDV to 1920 square pixel and import it into the EXCAM timeline.
h.264 files sizes vary hugely dedpending upon the quality factor. Sorry I can’t be more specific. I did a job recently where the h.264 sequences (to be played on 30′ screens in a conference) had to be delivered via FTP. We were amazed at how much we could reduce the quality before it became unacceptable. In effect we knocked two-thirds off the file size.

HDV records in 1920×1080 but puts it on tape as 1440×1080.
That is what you will be capturing.
Shooting in 30p is not suited for every situation.
If you want to keep things simple film in 60i which is interlaced if you want your project shown on tv on dvd. If you want BluRay you do not have a choise, its all interlaced.
Filesize is about 13 gig a hour (same as DV)
You can either export in 1920 or 1440. All players play at 1920.
If you export to 1920 the software handles the conversion. If you export to 1440 the player will handle the conversion.
Hope that makes sense.
