Keep original aspect ration when ripping Blu-ray Disc


07 Feb

(Submit Articles) When watching Blu-ray movie on a widescreen TV, you may find that the image do not always fits the screen well. Now that most BD movies are released in 2.39:1 aspect ratio, you get bars across the top and bottom of the screen. This is not a big problem with LCD TVs, as they should stay that way because that is how they are meant to be seen. However, it is a problem when you watch these movies with plasma TVs, because you have to use the 16:9 zoom feature because of burn-in issues. This leads to grainy pictures. In order to play 2.4:1 Blu-ray movie at full frame on 16:9 HDTV without black bars, there are two ways to go: either stretch the image to fit for 16:9 screens or crop the anamorphic picture to 16:9. This guide aims to tell you how to rip Blu-ray movie of 2.39:1 to fit for HDTV with Pavtube Blu-ray Ripper software.

Step 1. Load Blu-ray Disc and set subtitle and audio language.
Hook the BD drive to your PC, Place the Blu-ray Disc you’d like to rip into BD drive. Run the Pavtube Blu-ray Disc Ripper software, and click “Blu-ray Disc/DVD ROM” icon to load Blu-ray Disc from source drive. When your movie is now loaded as source, expand the folder and select the chapters to keep, and set subtitles as long as you like. If you would like to combine all selected Blu-ray Disc videos into one file, please check “Merge into one file”.

Step 2. Choose output format for watching Blu-ray movie on 16*9 display.
Click the Format bar, and choose a desired format in “Common Video” group. HD Video formats (1280*720, 1920*1080) are recommended for Blu-ray Disc. Here I select “HD Video>>DivX HD (*.avi) as output format. This format creates 1080p HD AVI video, which plays stunning on HDTV.

Step 3. Decide which method to follow for ripping anamorphic Blu-ray to HDTV.
A. Alter the 2.4:1 anamorphic Blu-ray movie to 1.78:1 ratio.
Click “Edit” button enter the Video Editor, switch to “Crop” tab, and drag the green frame in “Original Preview” window to crop out black bars. Uncheck the “Output keep original aspect ratio” box and click “OK” to back to main interface of the Blu-ray Disc Ripper.

Pros: everything is preserved and the picture takes up the whole screen, without black boarders.
Cons: you lose the OAR (original aspect ratio) and the movie is stretched.

B. Crop the 2.4:1 anamorphic image to fit for 16:9 displays.
Click “Edit” button enter the Video Editor, switch to “Crop” tab, and drag the green frame in “Original Preview” window to crop out black bars. Check the “Operation keep original aspect ratio” and drag the green frame in the “Original Preview” window to select the portion that you’d like to keep. Then click “OK” to back to main interface.

Pros: you get full-screen display of the movie and not lose aspect ratio.
Cons: this results in a loss of more than 25% of the original image.

C. Use the 2.4:1 OAR (original aspect ratio) of Blu-ray Disc.
Click “Edit” button enter the Video Editor, switch to “Crop” tab, check “Output keep original aspect ratio” box and click “OK” to confirm.

Pros: you get BD movie clips played in the way that they are meant to be seen, like playing Blu-ray Disc with PS3 or a regular BD player.
Cons: the movie is letterboxing and there are black boarders on top and bottom.

Step 4. Start copying cropped Blu-ray Disc to hard drive.
When back to the interface, click the “Convert” button to start cropping and converting Blu-ray Disc movie to hard drive. After conversion completes, click “Open” to find converted movie.

Common aspect ratios using in DVDs and Blu-ray Discs:
1.33 (4:3)
35 mm original silent film ratio, today commonly known in TV and video as 4:3. Also standard ratio for MPEG-2 video compression. This format is still used in many personal video cameras today and has influenced the selection or design of other aspect ratios. It is the standard 16 mm and Super 35mm ratio.
1.78:1 (16:9)
Video widescreen standard, used in high-definition television, one of three ratios specified for MPEG-2 video compression. Also used increasingly in personal video cameras.
1.85:1
35 mm US and UK widescreen standard for theatrical film. Introduced by Universal Pictures in May, 1953. Projects approximately 3 perforations ("perfs") of image space per 4 perf frame; films can be shot in 3-perf to save cost of film stock.
2.35:1
35 mm anamorphic prior to 1970, used by CinemaScope ("'Scope") and early Panavision. The anamorphic standard has subtly changed so that modern anamorphic productions are actually 2.39,[1] but often referred to as 2.35 anyway, due to old convention. (Note that anamorphic refers to the compression of the image on film to maximize an area slightly taller than standard 4-perf Academy aperture, but presents the widest of aspect ratios.)
2.39:1 (2.4:1)
35 mm anamorphic from 1970 onwards. 2.39:1 is sometimes rounded up to 2.40:1[1]. Often commercially branded as Panavision format or 'Scope.
