Anamorphic dvd to fullscreen vcd

[varunb]

Can any1 tell me how i can resize only certain portions of mpeg2 anamorphic movie to fullscreen with almost lossless quality. Actually the dvd is a telecined, anamorphic ntsc movie which i have successfully converted to 23.976fps using the forced film method in dgindex as the film % was 99. Now i just need to crop the black borders & resize only certain portions of the movie & then encode the movie to pal vcd format. Why I need to convert only certain scenes to fullscreen is bcoz some scenes have text which will go out of the screen if i crop the entire movie with 1:1 AR. SO can any1help me ? Is there any avisynth-scripting solution to it ?

Is there any way by which the scenes containing text get cropped & resized by 1:1 AR in such a way that the black borders also get reduced & the text also doesn't leave the screen ? I hope u guys understand what i am trying to say.

(When i talk about 'text', i mean the actual texts & not the subtitles. There are no subtitles in the movie.)

I dont get it really but the conversion from widescreen to fullscreen is flawed.

If you want fullscreen (with parts from left and right cropped) mixed with scenes that are letterboxed than you need to apply crop&resize to the required scenes and just resize to the other parts.

You actually want to do a pan&scan of the video? What you're describing (different cropping depending on the scene) is exactly that.

I would be interested if there's indeed free software that can do that.

Well according to my, there ain't any freeware that can do pan & scan & yes, I do mean pan-scan when i talked bout cropping. There's only 1 method & dat is conversion to avi using divx codec. Its 'square pixel' resize method has helped me a lot in cropping a lot of movie trailers accurately. I just hav to input some values in d left & right cropping box to calculate the exact cropping value which can remove the black bars. I must say dat its 'square pixel' method is a pan-scan method.

There's no way to do this "with almost lossless quality", especially if you want to make a VCD. Interestingly enough, the subject on your original post mentions VCD, but nowhere else do you talk about it, so I think the responders have overlooked that part of your post.

I strongly encourage you to make a letterboxed VCD and just live with it. Remember that VCD has a very low bit rate (1.150 Mbps) so letterboxing will reduce the size of the image that has to be encoded and will give you better results than trying to encode a full screen image. I sometimes buy commercial VCDs of Chinese language movies that I want to see but don't really want to pay DVD prices for. Commercial VCDs in Hong Kong are all letterboxed and have been for the past few years. It has increased the quality of the image quite a bit over the old pan and scan VCDs they used to do. It's very easy to convert your original movie to a letterboxed VCD. TMPGenc can do this. AVIsynth can do it, but you'll have to write some scripts.
