Encoding odd aspect ratios with TMPGEnc

[Paulcat]

One of the things that annoyed me with TMPGEnc is that it would only encode aspect ratios of 4:3, 16:9 and 2.21:1 in it's standard settings.

I have a few files that are 2:1 and even 2.5:1 and there is no internal setting for those in TMPGEnc.

My solution? Under 'settings', 'video', 'aspect ratio', change this to 16:9 (if the source is widescreen, might as well use the bitrate to encode in widescreen). This is the setting for the DVD itself, not the video you are encoding. Don't use 2.21 here as no dvd authoring software I know can use it.

Under 'settings','advanced','source aspect ratio', change this to 1:1 (VGA)

Under 'settings','advanced','video arrange method', change this to centre (custom size)

In the custom size menu, enter the following sizes based on the aspect ratio of your source material:

16:9 - 720x480
2:1 - 720x427
2.21:1 - 720x386
2.35:1 - 720x370
2.5:1 - 720x341

This way you don't have to crop anything to maintain a true aspect ratio.

I wonder if the following might be helpful to you.

There is a little app Jsoto wrote

that calculates the resizing parameters from the resolution of the input source.

This seems to be designed for AVISynth correct? It gives a few different number from my calculations...anyone else out there have any math for this?
