60P to 60i question

[ExFool]

When using a 60P source clip in a 60i standard NTSC project, will Edius take the first field from the first frame of the source clip, and second field from the second frame of the source clip, or it will simply double the first frame - thus basically giving me a 30P output instead of 60i?

Thanks,

I always assumed the latter but will need GV in japan to totally 100% confirm i feel.

Should make sense to use 1:1 field/frame ratio for best output!

a 50p clip looks fine here in 50i project, pans are smooth and not jerky as in 25p

I assume you will experience the same

I did a test and it looks like our theory is right... 60i output from 60P source looks butter smooth.

Still, can anyone confirm this for shure?

GV, this is the forum... you copy?

You don't believe your eyes?

As my NX doesn't output 1080p I also edit interlaced with 50p source footage.

Not sure if you trust my eyes but it looks pretty darn good to me :)

Nope, they are known for deceiving me - take my lady for example, I saw her and thought she's about 60 kilos... she's actually 90... oh wait, that was 20 years ago... lol... (please don't tell her).

Thanks guys, good to know that what should be, it actually is.

60P from my CX700 looks just as smooth on a 60P or 60i timeline.

If I'm not mistaken the spark 1080 @50p timeline is 1080 @50i output over HDMI, should look the same !

Yes that is true I think, but if Edius was changing 60P in a way that just took the odd or even fields that would be like 30P and would then not look smooth when a DVD or Bluray was made. Not the case as both Bluray and DVD look smooth when mixed with 60i from my NX5U or other AVCHD cameras. I leave the CX700 on 60P as it is better for getting stills from the video.

A way to test which frames are used by Edius in an interlaced project that is using 50P or 60P footage is play a clip where the camera is panning and set Edius view > pause fields to "frame". Motion will be smooth as described above by people but when paused will show interlace jaggies. These stair stepping jagggies prove both fields are coming from a different point in time, thus confirming it's separate frames that Edius is using to create these fields rather than any frame doubling going on.

While the smooth result is ok though at the cost of interlace artifacts when paused, it's definitely not the same eye popping quality of full 50P/60P from a proper 50/60P project previewed in full 50P with a Storm 3G.

I love my 3G!

Yes Claire, watching 60P direct from camera to TV there is a noticeable difference. Less difference on my Sony 240Hz interpolating TV that does a good job of smoothing out most things !!!
