Interlaced video, noninterlacedvideo, and progressive scanning
After Updating After Effects CC 2018 and AME CC 2018 for latest fixes (eg. The fix for the brush which only drew 1 circle when you wanted a line in AE), rendering now in AME CC 2018 from a file created in AE or I believe adding to media encoder queue from within AE only renders with software only not hardware accelerated. Support for Adobe CC 2020 (Premiere Pro, Media Encoder and After Effects) ffkroma updated to 4.2 like ffmpeg 4.2 (will automatically be updated) OSX: New 'AfterCodecs Desktop' standalone popup next to the plugins (in MediaCore/Autokroma AfterCodecs/) also available like on Windows, so you can access Global Settings & License more easily! Deinterlacing: The process of deinterlacing involves taking an interlaced video, which includes analog TV signals or 1080i signals, into a non-interlaced, or progressive, form. Interlaced video frames have two sub-fields that are taken within a sequence. These sub-fields are sequentially scanned in odd and even lines within the image sensor.
A. For interlaced video, entire upper field (odd-numberedlines) is drawn to screen first, from top to bottom, in one pass. B. Next,entire lower field (even-numbered lines) is drawn to screen, fromtop to bottom, in one pass. C. For noninterlacedvideo, entire frame (all lines in counting order) is drawn to screen,from top to bottom, in one pass.
Interlacing is a technique developed for transmittingtelevision signals using limited bandwidth. In an interlaced system,only half the number of horizontal lines for each frame of videoare transmitted at a time. Because of the speed of transmission,the afterglow of displays, and the persistence of vision, the viewer perceiveseach frame in full resolution. All of the analog television standardsuse interlacing. Digital television standards include both interlaced and noninterlaced varieties.Typically, interlaced signals are generated from interlaced scanning, whereasnoninterlaced signals are generated from progressive scanning.
Chris Pirazzi provides technical details of fields and interlacingon Lurker's Guide to Video website.
Trish and Chris Meyer provide various materials about interlacing,field order, field dominance, field rendering, and separating fields:

Fields in a clip can become reversed from the statein which they were originally acquired in any of the following ways:
The video capture card used to capture the footage isset to the field dominance opposite that of the source device,
The editing or animation software that last rendered theclip had the field dominance set opposite that of the original clip,
The clip is set to play backward.
Ordinarily, individual interlacedfields aren’t apparent to a viewer. However, playing a clip in slow-motion,creating a freeze frame, or exporting a field as a still image canmake a single field distinguishable. For these purposes, it is sometimes preferableto deinterlace the image—that is, replace pairs ofconsecutive interlaced fields with single non-interlaced frames.Premiere Pro can generate these new non-interlaced frames from thefields in one or two source frames.
One unwantedinterlacing artifact arises from a mismatch between the fieldorder of a clip, and that of a sequence. Field order specifieswhether the field of odd-numbered lines (the upper field) or thefield of even-numbered lines (the lower field) is drawn first. Forexample, placing a clip with upper field order in a sequence usinglower field order could result in jerky playback. You can correct thisproblem by reversing the field order of the clip so that it matchesthat of the project. You use the Reverse Field Dominance optionto reverse the field order.
- Select a clip in a Timeline panel or in the Projectpanel. Choose Clip > Video Options > Field Options.
- Select Reverse Field Dominance to change the order inwhich the clip fields play back.
- For Processing Options, select one of the following choices:
Doesn’t apply any of the Processing Options. Selectingthis option does not disable Reverse Field Dominance, if that optionis checked.
Converts each pair of consecutive progressive-scan (non-interlaced)frames into the two interlaced fields of a single frame. This alsoresults in the clip running at twice its original frame rate. Thisoption is useful for interlacing clips created by animation applicationsnot capable of generating interlaced frames. Ideally, you coulduse it to convert 60-fps progressive-scan animations into 30-fpsinterlaced video.
Converts interlaced fields into non-interlaced, progressive-scan, frames. This option is useful for clips you want to play in slow motion or in freeze frame. This option discards one field (retaining the dominant field specified for the project in the Fields setting in the New Sequence dialog box, General tab). Then it interpolates the missing lines based on the lines of the dominant field.
Note:
In a sequence with No Fields (Progressive Scan) selected in the Fields menu, Always Deinterlace retains the upper field. However, in this type of sequence, if you also select Reverse Field Dominance, Always Deinterlace retains the lower field.
Prevents thin horizontal details in an image from flickeringby slightly blurring the two fields together. An object as thinas one scan line flickers because it can appear only in every otherfield. This option blurs consecutive lines 50%; it does not deinterlacethe clip. It is especially useful for graphics containing thin horizontallines.
Note:
To improve the appearance of video whenthe clip speed is not 100%, turn on frame blending. Choose Clip >Video Options > Frame Blend.
In the Project panel, you can change the fieldorder of all instances of a clip in all sequences of a project.
- In the Project panel, right-click the clip forwhich you want to change the field order.

You can apply the field dominance to multiple clips in the timeline (or project panel). The dialog can be used for any valid clip or valid track items that are not nested sequences or have no closed captioning that are in the timeline. Mixed states are also supported for field dominance. If a selection has mixed states for the field dominance field then then the checkbox displays a mixed state UI. If you press OK without changing it, the selected clip states get maintained. However, mixed states are not supported for the field processing radio buttons. If the Field Processing field has mixed states, Premiere Pro displays the state of the first selected item in the Timeline or Project panel. If you press OK without changing anything, the state gets applied to all valid selected clips, overwriting any previous mixed state.
