I have to create a couple of DVDs using a bunch of videos that are already created. These videos have all the following specifications:
- Resolution: 1280 x 720
- Format: .mov (I believe using de H.264 codec)
- Video bitrare: around 10 Mbps
When I use any software to create DVDs (for example Adobe Encore) or to just convert the files to NTSC DVD format (for example Premiere), always using the 16:9 DVD output format (720 x 480) I notice the following 2 things:
- Two small vertical lines show on both sides
- The definition decreases A LOT (not just the resolution)
Point 1 doesn't concern me too much, it's not a big deal. Point 2 is actually pretty bad, the output definition of the videos is almost unacceptable, specially when the input videos have very good quality. I believe that this loss of definition might be because the difference in the aspect ratio of the pixels of the input format (square pixels) and output format (non-square pixels).
Is there any way I can keep the definition/quality of the output videos as high as possible? The input videos are what they are, I can't change them...
Capture 1 (input video, picture is a link):
Capture 2 (output video, picture is a link):
The encoding of the second video is: mpg-2 NTSC Widescreen, max quality (in Premiere) with target of 8 Mbps.
