premiere has an optical flow feature.

-Exporting time interpolated media
The Time Interpolation setting in the Export Settings dialog box (File > Export > Media) allows you to change the frame rate of the exported file by leveraging Optical Flow to interpolate the missing frames.

->now, this can work all the way from amazing to hardly at all. it all depends on the quality of your footage.

each station has their own guidelines

exporting 1080 would be essentially burning in black.
Most stations take letterbox with black but not dcp or vimeo.

depends what AR you want. 2.39 would be 1920/2.39 or 803. It’s always best to work in and export same AR so your text isn’t offset. most people do AR 2.4 800(Bluray scope) because some codecs don’t support an odd number of pixels.

here’s a cheat sheet

[Chris Wright]

2944×2160 is a ProRes format with black padding left/right, the active image is actually 2880×2160.

Currently there are two way depending on your lens choice:
a) 4:3 2.8K with anamorphic lenses
– set your project resolution to 2048×858
– set Input scaling preset to “Scale full frame with crop”

Since the 4:3 is way too wide for 2.39 we need to do two things: crop & scale.
for the 4:3 2.8K shot set sizing “Zoom” to 1.142 (2944/2578) and “Height” to 0.5 to squeeze the image.
Now you can edit your 2048×858 next to this shots.

Aspect Ratio = (Horizontal Resolution / Vertical Resolution) × Pixel Aspect Ratio

ts a big reduction in quality. you can upload 4k to youtube as youtube will automatically letterbox.

as you have surmised, going from anamorphic to 16:9 won’t be pretty.
Since:
Aspect Ratio = (Horizontal Resolution / Vertical Resolution) × Pixel Aspect Ratio

so your AR = 2.66666 square
and 16:9 = 1.77 square

To fit the player perfectly, encode at these resolutions:
2160p: 3840×2160
1440p: 2560×1440
1080p: 1920×1080

but if you had to keep AR, 2.6 square would be 1920/720 square pixels or 2880×1080.

anamorphic videos will be letterboxed in both 16:9 and 4:3 players. The player can only do this if the native aspect ratio of the video is maintained – i.e. don’t add black bars to the video itself.
Note: If you add letterboxing to a video before uploading it, the widescreen player will add vertical bars, resulting in black bars all around the video and a bad viewing experience.

well 1 pixel at a time is 255-235 or 20 pixels. so make a gradient with 20 pixels. would be easier in photoshop.

here’s a long thread how to do it

i wish i could say there’s a better option, but at that price, including lens, batteries, yea pretty much the gh4. the g7 doesn’t have vlog so may be a little cheaper, so it would be my second choice. Sony A6300 third choice.
