Changing the shape/size of an mpeg

[cawright1]

Hi there. I have an Mpeg that somebody transferred from a television show. The video size is kind of 'tall and thin' (sorry for the laymans language). I need to try and convert this to normal pal tv size. What is the best tool/way for doing this?

Possibly it has the wrong aspect ratio -- set at 4:3 when it's really widescreen (16:9).

A utility like Restream can change this easily.

Hi. Its a vcd type mpg not a dvd.

Here is a screenshot. I want the actual picture to fill the screen. (including the black borders). I have worked out how to change the screen size to various others, but I cannot find out how to change the actual pictures to fit the screen.

It looks like someone resized a half D1 frame to VCD without doubling the frame width (relative to the height). I'm assuming the dimensions of the frame are 352x240 since you say it's VCD:

Crop 80 pixels off the left and right sides. Resize what's left to 352x288. Encode back to PAL VCD compliant MPEG.

Restream may still work. Did you try?

Or perhaps http://mpgtx.sourceforge.net/

type mpgtx -h to see options.

I think you want
mpgtx -s -An Video.mpg

where -An is aspect ratio:
n=1 -> 1:1, n=2 -> 4:3, n=3 -> 16:9, n=4 -> 2.21:1

Hi. How do you do this?

[Radixmind]

with the appropriate software. if you do indeed have to crop the black bars off the picture and then resize the image, you're going to have to re-encode the video, so i would think Tmpgenc or VirtualdubMod would do the job. have a look at the TOOLS section on this site.

Should give you something like this

Thats fabulous. Just what I want.

Sorry, I'm a newbie with this stuff so, things that you may think are clear, are not to me.

Do I need to decompile the video, resize each individual frame and then recompile????

Load the mpeg into Virtualdubmpeg-2, then click on Video->Filters and add the Null Transform filter. Click OK, then click on Cropping, and crop off the black bars on either side. Click OK, then add the Resize filter. Resize to 352 x 288.

Finally, frameserve the results out to an mpeg encoder and re-encode to mpeg, then author and burn.

Edited for clarity. (below).

Frameserving is a way of passing video data from one program to another without the need to encode it to an intermediate file. The basics are simple. Set up your filters, start the frameserver to create a signpost file, load this file into your encoder, and encode.

This guide is for Virtualdub, but all the variants are similar enough for you to adapt : https://www.videohelp.com/oldguides/virtualdubframeserve

Thats fabulous thanks. Really appreciate your help, patience and education on this.

I followed the plan, and then just saved out as AVI from within virtualdub. I can take it from there.

not on mpeg1, no it won't

vdub is ill suited for the job too.
if you're going to frameserve use avisynth.

you can encode with vdub, and just remux, but it's a run-around.

avidemux is probably the easiest tool to use.

unless you're changing format and that's your final encode,
2 encodes are not part of the plan.
