Specifications

Max GOP Length: This parameter is used to specify the maximum GOP length for all videos on the DVD. For compliant

a compliant video, the maximum GOP length is 15 frames for PAL and 18 frames for NTSC material. However, most

DVD players will accept GOPs much longer than that. If you are recoding your video, then we recommend leaving this at

the default value to create a compliant DVD.

The VideoReDo authoring engine can only accept GOPs of up to 35 frames. So no matter what value you specify for

this parameter, VideoReDo will internally limit your GOPs to that value.

DVD Display mode: This option is used to set the display mode for 16:9 video on a 4:3 TV. The default option is

"Letterbox" which causes the DVD player to shrink down the video, with black bars on the top and bottom, so that the

entire picture fits onto the screen. The "Pan & Scan" option causes the DVD player to crop off the sides of the video so that

it fills the screen but at the cost of losing a bit of the picture. (You can convert the aspect ratio of the DVD to 4:3 through

the

cropping and resize option but this involves a time consuming recode. )

Remember these settings:

Check this box so that VideoReDo will retain these settings as the default for future DVDs.
