1080p 25 F55 into a 1080i 50 workflow

[Shane Ross]

No, the number indicates the number of IMAGES per second. 60i…60 images in an interlaced stream, so there are two images per frame, one for each field…30fps. 50i…interlaced, each field a different image, two per frame…25fps.

Bouke…shoot 1080i50. Look at the frame numbers on the timecode…does it go up to 50? Or go up to 24 and then 00? I’ll bet you it goes to 24, then 00. Then shoot 1080p50…look at the numbers. They will go up to 49, then 00. 1080i50 runs at 25fps….interlaced. 1080p25 runs at 25fps…progressive.

Last time.
READ WHAT I WRITE (and try to understand at least half of it, then you don’t make these stupid posts.)
I KNOW what it means, but it is A WRONG NOTATION.
I work with 25i all day, for the last 30+ years.

Ok, so over there you don’t have it called 1080i50…it’s called 1080i25? I hope I’m getting that right. Because here, it’s 1080i60 at 29.97 and it causes confusion.

As we have now. Sorry that I messedup.

Thanks for all the info Shane. Appreciate it.

Do you think there would be an avid/sapphire or Borris effect to help smooth out the stepping.

Cheers
