I'm not sure in what forum to post this question, but I guess this is the most appropiate one... I live in Europe, where the TV standard is PAL at 25fps, but most of the movies I download are in NTSC framerates. Most DVD-players in europe play both PAL and NTSC movies. The question I'm struggling with is; should I convert my movies to 25fps progressive or not? I read this article on divx.com, and I think I understand the whole 3:2 pulldown and interlaced video thing (but I might very well be way off), so here are my thoughts so far: http://www.divx.com/support/guides/guide.php?gid=10 I’m afraid my knowledge of progressive video is very, very limited. Please, please correct me if I am wrong about any of this (and I probably am). 'Film' to PAL can also be done by slightly increasing the speed of playback (1 frame more per second, not noticeable). This is not a ‘real’ frame rate conversion (it’s not creating any new frames, like Canopus Procoder does), But the quality of video stays intact (until you code it to MPEG2). One app I found wich does this is EO Video. Most importantly, it alters the audio stream, so A/V sync stays intact. But what if the source is 29.9fps… Did the encoder of the Xvid or Divx set the codec to preserve the interlace (and 3:2 info)? Could I simply remove the pulldown info, and get a 23.98fps movie? I know Divx can be set to preserve this info, but how do I tell? And how do I remove it? Once I’ve got a FILM frame rate, and want to create a NTSC DVD, 3:2 pulldown info has to be added to create a interlaced DVD. 3:2 pulldown is the cause of NTSC DVD’s jerky playback in scenes that are supposed to have a smooth and slow horizontal motion. But what happens when I encode the DVD progressive?? Interlaced PAL uses 2:2 pulldown, which plays back smoother. No frames need to be ‘created’, every frame is simply divided into two fields. As appose to 3:2 pulldown, where every 2 frames equal 5 fields. This is how I create DVD’s at this time: 1. I let EO video render the MPEG4 source, at 25fps, saving both video and audio uncompressed (which can take up to 85GB of space). MOTIVATION: a. Adobe premiere doesn’t accept compressed audio. b. Trying this with Virtual- or Nandub will cause issues when the audio is VBR Mp3 this (even if I let premiere handle the frame rate conversion). c. Separating the audio with –Dub will cause A/V sync issues. Because I’m coding to PAL, and even if I where not, VBR Mp3 would still cause sync issues. 2. I import the huge file into Premiere pro. I let the build in MAIN-CONCEPT MPEG codec handle the conversion to MPEG2 DVD. I set the standard to PAL, two passes and progressive. I let the surcode AC3 plugin render Ac3 stereo audio at 192kbps MOTIVATION: a. I like Premiere. It’s easy to encode to MPEG fully compliant with official DVD specifications, and ensures the file is accepted by Adobe Encore. b. AC3 stereo is less lossy than MP2, or so I’m told. c. The above makes me think I’m best off encoding PAL progressive (????) 3. I author the DVD using Encore DVD. MOTIVATION: a. Encore allows me to easily add subtitles, which is a must. Again, I simply like it. I realise this is a lengthy post, but I’m trying to make you guys understand exactly what I’m struggling with. Please advise. Sincerely, John.
