Does lagarith support aspect ratios?

[sphinx99]

I do not see any options in Lagarith for specifying an aspect ratio, yet opening a Lagarith-encoded file in GSpot shows a 3:2 display aspect ratio. Is this a default that GSpot displays in the absense of any AR information in the file, or is there a way to specify aspect ratio data for this codec?

I don't believe it does support aspect ratio tags. What is the actual resolution of your image ? Wild guess, shot in the dark, I bet it works out at 3:2 in square pixels.

Lagarith is intended as an intermediate codec for lossless intermediate encoding. AR is not so important because you can usually tell your editor what AR a clip is supposed to be, and most end delivery formats (Mpeg-2/4 etc) do support AR tags.

Hehe, and I'll go even farther out on a limb and hazard the guess that it's 720x480.

As the man says, Lagarith is only used as an intermediate file before reencoding to something else (MPEG-2 for DVD perhaps?). If for some peculiar reason of your own you have to check it out at the correct aspect ratio, make the change in a player. Since you've looked at the Configure portion of the Lagarith Codec and haven't seen any way to set a DAR, I think you can logically conclude there isn't a way to do that. Set the DAR in your MPEG-2 encoder (if that's the ultimate output format).

Thanks everyone, it was 720x480 and it turns out Gspot assumes square pixels unless being told otherwise.

Btw - My question was not about Lagarith but GSpot and how it displays AR. I was confused because I was certain Lagarith doesn't store this information or care, and yet GSpot was implying that it did.
