| I usually run Inverse Telecine when going from 3:2 Pulled down material to 24fps movies, and get spectacular results.
But what I am running into is full 30fps completely interlaced streams. Like a TV Sitcom, or live broadcasts. Now my only option is to deinterlace, and that leaves me with ghosted images. So I utilize Decomb521 in AviSynth. I know that this is a major problem, but does anyone have a better way to deinterlace? | ||

| Yadif is about the best AviSynth deinterlacer that runs at a bearable speed. TempGaussMC_beta1 is even better but it's really slow.

| Yeah, I tried that one too, and it does take a long time to recode. Isn't there a way of recombining the frames instead? | ||

| There are no complete frames in interlaced video. | ||

| What I meant was, isn't there a way to separate the fields, and then re-insert the frames inbetween. Basically you would achieve a half-resolution, but twice the frame rate. | ||

| You're probably not loading it correctly. You can find it here:
http://avisynth.org/warpenterprises/ There are 2 ways to load it. I load it as a C plugin: LoadCPlugin("C:\Path\To\Yadif.dll") | ||

I've been AviSynthing for almost 5 years now... and I never knew you could do that! I guess you learn something new every day. Thanks! | ||

Ahh.. be careful with what you say :lol: just as there are wolves that cloth themselves as sheep to hide their identity, like-wise are with interlace videos :wink: During the course of my pal/ntsc restoration research of the last three years, I came into contact with various video types and layouts that I unraveled, or restored back to progressive. Some where not fullframe but still restoreable without the sure signs of the zigzags/saw tooth effect. In fact, I just did a few more of these in some of my analog cable tv captures of this evening. These are for computer watching, though I have a rather odd way of watching them. I will try and upload (over dialup) of just such a demo in case anyone doubts me :) -vhelp 4885 | ||

I doubt you since, by definition, interlaced video means interlacing/combing/sawteeth during movement. Of course, progressive video is sometimes encoded as interlaced, but that's not the same thing and surely you know that already. Field blended video, such as you often get from bad standards conversions, may have a mix of progressive and interlaced frames. Hard telecined video will also be mixed (3 progressive followed by 2 interlaced frames in every 5 frame sequence). But an interlaced frame is comprised of fields created during 2 different points in time and will show interlacing during movement. There's just no getting around that. |
