Time Interpolation: Frame Sampling and Opitcal Flow in PPro, then again in Media Encoder?

[Letty2019]

Hiya,

say I have a sequence in PPro, and some of the clips are slow mo.  Most of the clips are using standard "Frame Sampling" but the slow mo clips are using "Optical Flow" for the time interpolation.

Now, when I got to export it all thru Media Encoder, at the bottom there is a little drop down menu that wants me to select the Time Interpolation....  3 choices,   Frame Sampling, Blending or Opitcal.

What should I check?  My export has regular and slo mo. Seems odd to have to select one at export when the sequence has multi selections.  

Please advise,

Thanks!
Letty

The settings in the export settings affect the entire sequence.

You dont check them, unless you are e.g. exporting to a different framerate.

In PPro seq: when I changed the speed of a clip, I would select opitical for the time interpolation for just that one clip.

All other clips are the default 'frame sampling'

But in Media Encoder settings page, it requires a selection to be made.  (can't leave it blank)  frame sampling, blending, or optical. (located close to the bottom of the settings menu)

I'm assuming to leave it on 'frame sampling' but not positive. That selection would throw off the opitical selection for the slo mo clips in the sequence?

Thanks for your reply.

Read my answer again.

I'm not exporting to a different frame rate.

The AME export settings still requires a selection in the drop down menu.

The default is 'frame sampling'.

what did I miss?  The drop down menu is not active? Caz it seems to be active.

[Ann Bens]

If you are not exporting to a different framerate you dont check the boxes, leave it default. Cannot be more simple than that.

[Letty2019]

I still don't know what boxes you are referring to.

I'm referring to the drop down menu selector that appears to be active towards the bottom of the AME settings pop up page, when you export from the ppro timeline.

Reason asking is, it seems to be an active selection.  It's not gray'd out.

[Ann Bens]

Yes I gathered you meant that.

The answer is still the same.

Hover of the box and read the text.

[Letty2019]

Answer is not still the same.

The issue was never answered.

Hovering over the box only describes the selections.

It doesn't answer which one should be selected if the original sequence has clips that use regular frame sampling and some clips are using Optical.

This drop down menu seems to want control over the entire export in that regards.

Don't worry about it.  I'll try google again and see if I can find an answer.

I find it hilarious how you failed to realize after so many replies that Time Interpolation isn't an optional checkbox but a mandatory drop-down. If people could downvote all of your replies, I'm sure they would.

just keep export settings (Time Interpolation) at frame sampling

since you are not exporting to different frame rates,

Optical Flow still applies to and affects the clips you assigned that to in your sequence... 

[Letty2019]

ahhhh.  Thank you very much.  That makes sense.

[Ann Bens]

Optical flow in the export settings analyzes the entire sequence not just the clips which have OF applied.

[Carlos Ziade]

I said optical Flow for clips in the sequence Ann.. Sequence = Timeline not export settings

[Carlos Ziade]

Ann Bens, you can apply optical flow to individual clips in the timeline

Hi Carlos, I think Ann is aware if this since she is one of the most talented Premiere Pro helper in this forum.:)

I know Ann very well
