Greetings,
I've scoured Google, Doom9 and these forums for information on aspect ratios but I still haven't learned enough to feel comfortable when it comes to putting an mkv on DVD.
I have an mkv that is 1920x800 (2.40:1) which I'd like to put on a DVD9. Here are some thoughts:
1. Simply resize it to 720x480 and use TMPGEnc to convert it with a 16x9 DAR flag
2. Resize it to 720x356 and add black bars to make it 720x480 and tell TMPGEnc it is a "16x9 display" source
3. Add black bars to make it 1920x1080 (which makes it 16x9), resize it to 720x480 and tell TMPGEnc it is a "16x9 display" source
The problem I'm wrestling with is that adding the black bars during encoding takes away from the useable lines for the actual picture. I always figured that the player should be adding the black bars during playback.
On the other hand, using option #1 would make the playback look squished wouldn't it (it isn't really 16:9). I don't particularly want to crop but I want to preserve the quality as best I can. Any recommendations would be most appreciated.
Summary:
What is the best method (ie: math) for putting a 2.40:1 anamorphic source onto a 16:9 DVD without cropping or distortion? |

Use the resize filter change the the top Absolute (pixels) to 720 x 405 and set the Aspect Ratio to 16:9
Test the above and check all is ok by viewing the output screen after the adjustments have been made.
By finding an object in the video that is round or circular a watch, clock, wheel, ball or other circular round shape. Preferably for most of these the object should be face on or best near face on angle. Often a video will have many such shapes face on. The shape needs to be be circular and round only not elliptical. Round and circular are exact size horizontal as they are vertical, if need to measure on screen use lint free cloth or maybe if careful by using a very soft tissue. Or better if software exists to do this using the mouse maybe some paint package via copy and paste. Image from virtualdub - Video - Copy output frame to clipboard.

Thanks for the replies and the link.
My concern with using either method is that I'm adding black bars in VirtualDub which means they are actually encoded into the video thereby losing space that could be used for actual picture data.
I thought there was some way to resize it so that it would look squished when played back as an AVI (without the need for padding) but when played as an mpeg2 with the 16:9 flag set it would be streched properly. |

Load your source video into virtualdub and select from menu Video - Copy Source Frame To Clipboard open some picture software paste the picture. The picture should have pasted with the same size dimensions as your video. Save it as then upload the picture to some picture server and post the url to it here |
