[David Edwards] “I guess I incorrectly assumed there was some way to splice/merge segments just for simple edits.”
With smart rendering any untouched clips are copied instead of recompressed, if I understand correctly. It might not be the best option for you now because the preview files would need to be rendered.

[commercial hack] “Trouble is, I’m not getting both video layers (V1, V2) in the new timeline when I click on overlay, I get both tracks on V1. How can I separate the tracks into the new timeline?”
Not sure what you mean. Please post a screen capture of your workspace.

Another option is to use the Reference Monitor with Gang to Program Monitor disabled.

– Does image quality look good when viewing the composition in AE?
– What is the bit depth for the AE project (8, 16, or 32-bpc)?
– Have you tried importing the AE composition into Premiere Pro using the Dynamic Link function? -
First create a new 1280×720 sequence and drag the video onto the timeline. Open the Effect Controls panel for the clip. Click the arrow next to the Motion effect to reveal the controls. The next step will depend on how you would like the final output to appear:
Option 1) Crop the top and bottom: Change the Vertical position to move the clip up or down and trim the edges as desired. Use keyframes to change the setting at the start and end of each shot you would like to crop differently.
Option 2) Downscale and add pillars: Set Scale to 90%. When encoding, enable Maximum Render Quality in the Export panel (optional). Note: You can achieve the same result just by exporting the video at 1280×720 without creating a new sequence.
Option 3) Squeeze vertically: Disable Uniform Scale, set Scale to 90%, and leave Scale Width at 100%. Enable Maximum Render Quality in the Export panel (optional).

Smart rendering is another option. You would render ProRes preview files, then enable “Use Previews” in the export panel.
To make quick fixes on your current project, import the ProRes file and insert it in a new sequence. Overlay the desired changes on another track (or splice out the old footage with the razor tool). If appropriate, replace the audio stream from the ProRes file with the original audio. Even though the ProRes file will be expanded and re-encoded, it should not take long when there are no effects to render. There should not be any noticeable degradation in quality with ProRes 422(HQ).

In general, the file is encoded to meet the target bitrate. Based on the file sizes it sounds like your Vimeo setting is about twice the automatic setting. Note that the recommended Vimeo bitrate is for submitting the file prior to recompression. The final Vimeo bitrate is about 2500 kbps for a 1280×720 file.
I am having trouble with the math using the numbers in your post. The bitrate for the automatic setting can be calculated as follows:
Bitrate = File Size / Duration
= (180MB) / (215s) x (8 b/B) x (1024 kb/Mb)
= 6858 kbpsThis seems high for a 1280×720 automatic setting. What is the frame rate?
The encoded bitrate using the Vimeo setting is as follows:
(351MB) / (215s) x (8 b/B) x (1024 kb/Mb) = 13,374 kbps
This is much higher than 7000 kbps.
Please confirm the file sizes and length of video. If the numbers in the original post are correct, please take screen shots of the export panel with the automatic and Vimeo settings.

The crop effect would be the most common approach. You could also insert the clip into a sequence that is sized to the desired dimensions, and then embed the sequence into your main timeline.

DNxHD and AVC-Intra are similar to ProRes. You could also use uncompressed 4:2:2 YUV; the file will be about 11GB.

Use garbage mattes to cut out the TV screens. Move or change the mattes with keyframes as necessary. If the cutouts move around significantly, use motion trackers in After Effects to follow the television screens, and then link the replacement images to the tracking data. The following post provides more informaion:
