Yes, all Blu-ray players support 1080/60i as part of the standard Blu-ray specs. Some also support playing 1080p60 AVCHD video files (though 1080p60 isn't part of the standard Blu-ray specs).
Tell me please what happened when I record on 60p and convert it with software into 60i: does it cut half of my video quality? Like every second line of every frame removed, right?
Yes, you'd end up with 60 fields per second instead of 60 frames per second and it would have with half the lines. How much visible quality loss there was it would depend.
Same question about converting 30p to 30i while blu-ray burning: does it reduce video quality?
There isn't a 30i so I assume you mean 60i (60 interlaced fields per second). 60i should be able to store 30p footage. In theory, the only quality loss should be from recompression. You shouldn't be dropping any lines.
I was wrong saying my camera had 3 video modes to record, it actually supports only progressive mode for recording, the only option to choose I have is amount of fps: 30 or 60 (please see me corrected post above). So what I currently have been doing is recording all my video in 1080/30p, than during import it onto computer memory for editing I'm asked if I need it imported as interlaced or progressive, I choose interlaced 30fps.
If it really is recording 30 progressive frames per second, I don't see why, on import, you tell it to interpret it as interlaced footage. Wouldn't you only tell it to interpret it as interlaced if it was recorded as interlaced?
Than same question during burning, I set it up to be 1080/30i (CyberLink PowerDirector 10). So I wonder if the video quality I initially recording differs from what I watch on tv having this process? Please advise. Thank you
You mean watching the finished encode? Recompressing the video could reduce the quality from the original.Edited by Joe Bloggs - 1/22/13 at 11:44am
