FRAME COMPARISON FOR DIGITAL CROPPED VIDEO
Canon 5D3 / Canon EF 50mm 1:1.8
Manual Mode 1/125, f1.8, ISO 100, WB 5500k
Setup

Here is the process I used:
1. Took a photo a full RAW
2. Took a video at 1920x1080 24 fps with Neutral Picture Style
3. Took a standard RAW video at 1920x1080 24 fps
5. Took a Zoomed RAW video at 5X at 1920x1080 24 fps (Cropped Digital Video)
6. Extracted the dng frames from the RAW videos
7. Extracted the tiff frames from the MOV (canon) video
8. Processed all frames in photoshop with following corrections:
DNG:
1. Changed WB to 5500 and +6 Tint since this was the values from the CR2 file
2. Took all sharpening out
3. Opened to Photoshop and adjusted Levels
4. Sharpened with Unsharp mask 50%, radious 0.9 pix, Threshold 0
CR2:
1. Took all sharpening out
3. Opened to Photoshop and adjusted Levels
3. Opened to Photoshop and adjusted Levels
4. Sharpened with Unsharp mask 50%, radious 0.9 pix, Threshold 0
Tiff:
1. Opened to Photoshop and adjusted Levels
2. Opened to Photoshop and adjusted Levels
3. Sharpened with Unsharp mask 50%, radious 0.9 pix, Threshold 0
Final Comparison
CR2 versus Zoomed DNG

In the photo above it is clear that the detail of the zoomed RAW video is equal to the detail in the CR2 image.
Tiff versus no zoom DNG

In the above photo it is clear that the detail, dynamic range, noise, and sharpening characteristics of the normal RAW video is superior than MOV.
