Confused over which field order ?

[beammeup]

Hi

I used to capture and edit in Vegas... Then render a large AVI... then open and encode in Procoder.

The source file was PAL lower field first so I made the target file the same lower field first.

I am now framserving from vegas to procoder and here's what happen yesterday.

I noticed that my source file was upper field first, ( don't ask me why, because it was captured from the same camcorder as a million lower field first videos.

I then frameserved to Procoder, but when I loaded the source framserved file into procoder, it identified the file as lower field first.

Anyone know why ?

Also, does it really mater if one gets the fields reversed when creating a mpg2 file ?

What is the visual effect of doing this ?


Cheers
Scott

procoder DOES NOT know the field order, it only guesses OR uses the last field order of the same type of file ....


this was covered on the procoder forum ..


it will read mpeg header field order though ..

so you have to tell it your field order - or it does not know (its just guessing) ..

BUT

IT DOES NOT MATTER THE FIELD ORDER OUTPUT SETTINGS IN PROCODER (if you have the input set correctly)


Procoder will properly offset the top line and reverse the field order - and i have found that ntsc to pal conversions work better (for some odd reason) always reversing the output FO ..
