Is there anything that can make a divx movie full screen when you play it instead of the letterbox format.?

some of the players have the ability to stretch the picture, but I dont think you really want that. Without croping the actual video, there is no way to make a letterbox movie be screen height without messing with the aspect ratio...

srry...

Yes, you would need to crop the sides. When you are setting up your AVI synth script instead of just cropping the black, you would also have to crop the sides. If you are not using AVI synth then what ever you are using should have crop/resize features... The values would also depend on whether you are dealing with a 16:9 PAL or NTSC film.

Correct me if I'm wrong, but I think that you loose around 25% of the width of you go from 16:9 to 4:3.

For instance for a PAL movie you would have to crop from 720x576 to 540x576 and then resize to say 512x384. Where as if you leave it as 16:19 it stays at 720x576 and then scales down to say 640x360.

Through cropping, you also need to re-encode the entire movie again.
You can do this through virtualdub.

Plus when you crop, you'll lose some of the picture on the left and right sides, and you might crop stuff out that you don't want to. In other words, when you convert it to full screen, it's not pan-and-scan where the screen follows the action; the picture will remain fixed.

You might want to check this out.. From what I gather it will let you crop in real time, so no need to re-encode or perminatly crop the sides off.

I've just tried it m8 but not sure if I completed the setup, drop the bicubic_resizer.ax in the window 32 folder / open reg_bicubic. and thats where it stop for me, could you or anyone else explain how I go about Using mediaplayer 6.4 or
similar to get properties from filter it has resolutution setting and bicubic
setting. I find setting b = 0 and c = 1.0 quite good (default). Those are
exactly same setting as in avisynth. Bicubic higher the
c is sharper the picture is b = 0 and c = 1.5 might be better for really blurry
material. And anyone knows what flip picture setting is. And you need allways to
press save buttong to save your settings. Only flipping works in realtime other
setting only start working as soon as you load the next file.

I have no idea what the above means thea was just a quick copy & paste. Also is this proggy meant to make your movie larger at top and bottom, left and right sizes which is what I need..

It is a direct show filter capable of cropping and resizing in real time. Just set the filter up with the way you want it. Save and then load ya movie. What exactly is your question??

Are you talking about when your making a divx movie if so thats where we are getting our wires cross, I was talking about when you d/l a movie and you want it to be full screen instead of the letterbox format.

Originaly I was talking about re-encoding a movie which you had downloaded, to perminantly get rid of the letterbox format.. Then it occured to me that it was possible to do it without re-encoding.

Once you have installed the filter you can change it's settings the by going into it's properties. Some settings will take effect instantly others, you have to open the movie again..

Upon actually testing this filter though, I find that you can only crop the top/bottom.. You can't crop the sides, so it looks like if you want to get rid of the widescreen then you are going to have to rencode, which will take time and cause loss in quality.

So unless someone knows a way to crop the sides in real time, then there is no real point to this... Movies look much better in widescreen anyway.

You could use AVISynth to do it real time, however you would have no audio, unless you had a PCM wave sound file.

I use avisynth and what celtic said, you will lose some of the sides of the movie about 10-20%
