.ts with 1280x1080i

[SBaT]

As some HDTV is sent as 1280x1080i 30fps is there anything special I should note in my .asv when encoding it to 720p?

What is a '.asv'?

If you're talking about an Avisynth script, then please post it.

Avisynth (avs) was what I was aiming for :)
Maybe I should have tried to be more clear also.
With 1920x1080i .ts I have been able to use as the simplest only
tfm().tdecimate()
crop( 0, 0, 0, -8)
LanczosResize(1280,720)

Now as the source is 1280x1080i should I need to adjust my .avs filter in some different way as I go now from 1920->1280 in the source? I tried to search the forums but couldnt find anything on DTV or the resolution. If resizing 1080 to 720 is just enough I'm happy with that. I was suprised on the resolution as I had no idea that HDTV was sent with that resolution also and used to save bandwith.

What's the aspect ratio of that video? If it's anything other than 1.78:1 you should pay attention not to resize to 1280x720, but to e.g. 960x720.

I'm asking because 1280x1080 is 1.19:1 (with square pixels).

[edit] Typo, I meant 1.19 not 1.9

I'm asking because 1280x1080 is 1.9:1 (with square pixels).Don't you mean 1.185:1?

Its 1.78:1 /16:9 here is a sample (http://rapidshare.de/files/15800231/sample.ts.html) just in case.

The sample is pure soft 3:2 pulldown. So you can use Force Film in DGIndex instead of tfm.tdecimate. It will be much faster to process it that way.

Thankyou for all the help. I will really need to read up on how identify sources so that I can trust myselfe on what I'm doing. When I was running preview in DGIndex for about 6min
I had information jumping Film ~70-80% and Video 7-25% ,frame type Progressive to some Interlaced

The clip you gave us was all film. So don't blindly follow my advice if the film percentage for the *whole movie* is less.
