AVStoDVD + HCenc keeps giving me interlaced output. Why?
Hi,
I've just started using HCenc to convert uncompressed AVI to mpg2. I use AVStoDVD with it. I'm brand new to this so maybe I'm missing something..... My source video is ('progressive' NTSC 23.976fps uncompressed avi). But no matter what I do, the HCenc keeps giving me an 'interlaced' mpg2 file. I assume to make the encoder do ''progressive'' you just tick the "DV source" box, so that the interlaced options become grey'd out? But still when it's encoding it says ("Interlaced = no") and ("TFF/BFF = BFF"). And when I check out the outputted mpg2 file, it is indeed 'interlaced'! Why? Please can someone help? Here are the settings I used. I assure you my source video is progressive. Thanks! |

Maybe GSpot is wrong? Use MediaInfo, much more reliable.
You can set the BFF flag and still have a progressive footage. Progressive overrides the field order. In other words for an interlaced source the field order is mandatory, for a progressive it is irrelevant. To close the loop, could you run again the AVStoDVD project using default settings (without touching anything in Title Edit)? Then, please post the complete AVStoDVD project log file. Bye |

ok, thanks for that info, good to know. And I'll do that.
And possibly what I'm about to tell you might be part of the issue. the source video (uncompressed AVI) isn't technically "progressive". It was a PAL (interlaced) mpg2 that I converted to NTSC 23.976fps in Sony Vegas (the proper way) and then rendered as "Progressive" without "de-interlacing". I did this for a reason. Because for some reason, rendering in the correct Interlaced field order caused the output avi to have major ugly ghosting. Why, i do not know. So I found that if I rendered as "progressive" - no ghosting! So can AVStoDVD/HCEnc actually tell that my source video isn't truly ''progressive''? Maybe this was the problem all along. :S Last edited by Butcher Wing; 27th November 2012 at 21:42. |

It's a complicated one.
I need it to be NTSC because it's a movie trailer going to be put on an NTSC dvd as a bonus feature. Hence the converting to NTSC. But weirdly it was coming out with serious ghosting when I rendered as interlaced. Even though the source itself was interlaced. This doesn't usually happen. Anyway, I found that rendering as 'Progressive' sorted this problem. Weird? Anyway, after encoding that uncompressed avi to mpg2 in HCenc, the resulting mpg2 file is a mixture of progressive and interlaced, according to a friend who checked it out for me. Not really what I wanted, but it'll do. So not to worry. Last edited by Butcher Wing; 29th November 2012 at 01:04. |

And as MrC implies, your conversion method is screwy. |
