Frame Rate for shooting in different countries?

[Andreas_Gumm]

Here in North America, frame blending is rejected by broadcasters for everything except television commercials, but even then they don't like it.
I would guess most European broadcasters are the same.

Same here in Europe!
And even frame dropping qualifies to get rejected by serious broadcast stations!

Frame dropping looks terrible.
If anything you wan too rather repeat frames/fields (pulldown approach) rather than remove frames.

Yes, indeed!
But here repeating fields or frames makes no sense in a 29.97 -> 25 process.
I've just expected some bad "conversion" shemes with unwanted frame drops
when someone states a magical and easy fps conversion.

Hello I want to shoot 23.98 with my A cam and want do do some slowmotion with B cam what framerate must i shoot to match the 23.98 project? 60 frames? I live in pal land.

The best solution for slow motion is to shoot at the framerate that that allows you to play back at your chosen project framerate giving you the slow motion speed that you require.

For example, if your master project is 23.98 and you shoot 29.97p for slow motion, when you play the 29.97p footage back at the project framerate of 23.98, you get a slow motion speed of 80% (23.98/29.97=0.80....). If you shoot 47.96 (48fps) you would get a 50% slow motion speed.

This method avoids frame interpolation and blending in creating the slow motion in post.

So the answer to your question is, you need to do the math to figure out what slow motion speed you want, and adjust your framerate to get it. otherwise you have to settle for the adjustment in post.

Ideally you don't want to do it this way, but play existing frames at slower rate. In Edius this is done by changing source fps to your timeline fps and than dragging source to timeline.
If you drag some high fps source to your e.g. 23.98p timeline and than play with speed (or not) you will have interpolated frames (or skipped/repeated). You would need perfect: original/new fps=n cases to avid any conversion problems.

Are you saying not to do what I suggested, even though you are suggesting the exact same thing? (That being to play back a higher framerate at the project's framerate)

I totally understood you Bern, and you are absolutely right. Furthermore, it's the only way to get smooth and un-interpolated (no frame blending) in Edius natively. Andrew already knows this, I think he may have simply misunderstood your post.

Thank you all for your replays and for your help.

I figured it was a misinterpretation. Just wanted to clarify.

Yes :)

Not sure are how I have read it, but you've suggested the same.

No problem, just a clarification.

Yes, I am the said Avisynth novice, and indeed have found the fps conversion using this method to be outstanding - better than any software conversion I've seen. As good or better than a lot of the hardware converted stuff I've been given over the years. I'm definitely a believer now, and a daily user.

I tried out Episode trial version as well, but couldn't get very impressive results out of it, or any consistency. And at $1,200 a license (pro), that's not too inviting. I understand that, say, 50i to 60i is a very complex conversion to make, which is why there is hardly any software out there to do it well (no frame blends, no nearest-frame glitches). But More4K's Avisynth method does indeed deliver the goods AND it enables conversion directly from Edius timeline! Or using a third party application, whichever is more convenient.

As mentioned, I have zero prior experience with dealing with Avisynth or scripts in general, but had little trouble getting my sea legs and getting stellar fps flips right in my edit suite!

For anyone who deals with a lot of mixed fps materials, or delivers content from PAL to NTSC world or vice versa, would we well advised to check out this option. I only wish I'd found this out ten years ago - a lot of my stuff would have looked so much better...
