[Darby Edelen] “So the interlacing I see in that footage is a common problem, but I’m not sure if it’s due to the resizing that occurred when you uploaded it or if it’s in the source footage. If you turn Separate Fields Off and zoom into your footage do you see single lines of interlacing in that fast motion portion? Or do they look more like big fat lines as seen in the top two images on this site: https://www.100fps.com/
“

I’m beginning to think it is the latter….

Here is a screenshot of my footage during motion with separate fields set to off. This would be the fat lines you were referring to right?

These are the settings I just rendered with that outputted the same interlaced motion as the original. I double checked that the composition frame rate is set to 25fps. Same result when the footage interpretation is set to lower OR higher field separation.

Any ideas?

Thanks

Thank you, your suggestion worked for the aspect ratio dilemma.

As for the motion choppiness, there doesn’t seem to be any difference in the motion when I set the separate fields parameter to either upper or lower field first. In both cases when I step through in the footage panel, I see motion only every other frame, and in between the lines shift vertically, no backwards movement in either one.

Am I testing it wrong?
Is it possible my footage is interlaced permanently? Is there such a thing?
I just can’t seem to find any sort of relief in the atrociousness of the motion in this footage no matter what I try.

I’ve switched it to lower fields, higher fields, rendered it both ways…. what am I missing?

[Darby Edelen] “In After Effects the output frame rate and resolution is defined in the Composition Settings of the composition you are rendering (although it can be overridden in the Render Settings). However, you should also confirm that the frame rate of the footage source in the project panel is correct. You can alter this as well as the field order by right clicking the footage in the project panel and using Interpret Footage > Main…
“
I had the footage interpreted with 25fps and the composition as 50fps. Is this correct?

[Darby Edelen] “You should use the PAL D1/DV Widescreen Square Pixel composition preset if you want the rendered movie to be widescreen on square pixel devices (computer displays, HDTVs).”

Fixed! thanks!

[Darby Edelen] “You can upload images to the forum using the Image Upload button above the Message field where you reply (it’s the 3rd from the right in a row of buttons). A short clip may be better as it’s impossible to figure out field order from a still image. There’s a button for that too :)”

Here is what I’m up against. You can see the motion distortion at the very end. Also it got re-encoded to a different size when I uploaded it so hopefully that won’t derail your analysis :/

Thanks!!

Thanks for the suggestions!

I’m not sure I am adjusting the frame rate and resolution correctly. Should I just be be doing that in the comp settings or is it during the actual compressing?
I’m not seeing a huge difference no matter what I do even with the blur, timewarp, and resolution/fps adjustments ….
And another problem is that when I drag one of the clips onto the new comp button it is creating a composition that is 4:3 instead of widescreen and in addition to that, when I view the footage in AE it is 4:3 even though it says the aspect ratio is 1.46. Although when I turn pixel aspect ratio correction on it goes to widescreen but of course doesn’t export that way.

Is there an email address I can send you some stills of what I’m working with to you?

Let me know, again thanks for your help!

Hey Darby thanks for the response.

Thanks for the response Dave.
I basically just copied the VOB files from the DVD and renamed them to .mpg.

Is there a more appropriate way to capture the footage?

Thanks
