Crop and Resize: prepare for / how to
Time
OK, now I'm confused. I used video>frame rate>reconstruct from field - manual and saved the avi (direct stream copy). I tested this on a clip with 319 frames. So I thought the clip now would have less then 319 frames. But it still has 319 frames. So I repeated the process now also changing the framerate to 23.976. Now I get a clip of again 319 frames, but virtualdub says it has a 23.976 framerate. OK I understand the ammount of pictures can be the same and the framerate can change but I thought IVTC actually removed frames. Can someone please try and explain this whole pulldown system to me because I don't get it anymore.

I don't think it has somthing to do with pulldown. As far as I understand anything of 3:2, 2:3, inverse 3:2 etc. I'm a PAL guy. No, I have to say after upping the contrast and downing the brightness there's almost no trembling left. I'm not going to use pulldown, I'll keep it at 29.970 frames per second. Only problem left is resizing. Quality is going down after resizing. So I'm thinking about keeping it at fullscreen unless I find a lossless way to resize. I tried resizing in virtualdub (I'm doing everything in virtualdub).

Hi. Yes I can make a short segment. I just have to figure out how to make it available... I encode my avis using cce. Normally, bottom field first. If this is no good, I mark top field first. The field order in this case is bottom field first. Sometimes in a very bright part in a movie the image seems to tremble, in my avis it's like that thru the entire avi. I also used virtualdub for resizing. I cropped using nultransform (104 from top, 100 from bottom, just leaving the image, cutting of entire black bars). Then I resize to 720 x 360. I expand it to letterbox to 720 x 480. For the filter mode I used the lanczos filter, you can also select "interlacing (not recommended for enlarging)" well seems to me I must not mark it. But the problem is when I burn a piece of encoded avi on dvd to check it on my tv it seems the lines of the interlacing artifacts in the picture are twice as big and very well visible. Normally when I encode interlaced PAL material the image is very smooth on tv, in this case it's the oposite.

Hi. I want to make a ld to dvd transfer. I captured the movies on my pc. But the trouble is the image trembles/shake ( i don't excactly know how to put it in english). When I deinterlace the image is good, but ofcourse I don't want to deinterlace since this reduces the quality. My second problem is, when I resize (to 16:9 anamorphic) interlacing artifacts become visible on the tv screen. I normally work with PAL source so I'm new to NTSC material. Does anyone know how I can solve this problems? Thanks!
