converting from 1080i50 to 720p25 makes audio delayed

[adom]

Hello,

I'm new to avisynth - just playing with basic scripts like one below:

DirectShowSource("e:\_video.ts")
assumeTFF()
separateFields()
selectOdd()
crop(8,4,-0,-4)
Spline64Resize(800,448)


my source is from hd pvr (hauppauge) recorded as *.ts

and when I open this in vDub and encode with xvid then audio is not in sync with video.
This is vissible on my pmp (portable media player) - ~1 sec delay.
On my computer everything seems to be fine (but I suspect there is something wrong as well)

Thanks for any advice.

I would really appreciate any help, just pointing to what may be wrong would be fine.
I just cannot fix this by myself.

I had the same issue, until I realized that my PMP was the problem. When trying to encode with xvid, the audio got a progressive out of sync, even with qpel, packed bitstream, close gov, variance aq and other options off. I also tried with profiles with no success. Finally, I decided to change encoder with ffdshow's xvid, which worked better (related to audio sync) but still not "perfect" with my PMP. I didn't continue searching, but... maybe Divx?

SAT recordings usually have up to 1 second of delay. You need to fix this first before going into any video processing.
