Increase the resolution of a video

[thiyagups]

I have video file (mpg) of resolution of 176X 144 . If I am making a vcd with this file the picture comes very poor on tv. So I want to improve the resolution of the video to 512 X 384. Is there any way to improve the quality or video size? If so, what tool should I use. Kindly help.

Also is there any tool to find the resolution and birate for a video file?

Thanks
Thiyagu

Nope. Increasing the resolution of a video will degrade it regardless of the situation. If you increased the resolution and played it back on your monitor full screen the original would look better that the higher resolution one.

The quality of the video will never be better than what you start with. While there are some tools that will permit you to process the footage (1. expand pixel size, 2. blur/degrade the image, 3. unsharp mask it), you can readily see that this will just make it a mess (albeit larger).

I believe there's "mpeg info" (or something similarly named) that will provide the details of the mpeg file.

I have to take issue with this statement, otherwise why bother with all those avisynth and virtualdub filters ? The first rule of video is first do no harm. The output should not be worse than the source. The second is try to improve on the source. Not always possible, granted (hence rule one).

In this case you may well be able to improve the quality of the video, however resizing it to double it's current (low) resolution isn't going to do that.

The latest version of g-spot can handle mpeg files, as well as most other formats. Find it in the tools section.

Look at it this way ....

You have 25344 pixels of information in your source file. You want 196608 pixels in your putput file, meaning the computer has to figure out / embellish / guesstimate the contents of 171264 pixels, or 87% of your pocture. Pure and simply, it ain't gonna happen. Let me rephrase that - it can happen, but it won't be pretty. TBH, even quadrupling the frame size to VCD-compliant 352 x 288 will be a task in itself to keep watchable, and then you've got the DVD Player doing a resize to full-screen on playback. I conclude with - it ain't gonna happen.

For educational purposes, knock yourself out. But I wouldn't waste your time if I were you.

GSpot. The latest Beta (2.52) supports MPEG video.

I'm sorry that you're rationalizing how you waste your time.

Video can be improved, don't let anybody tell you differently, but that's generally because you are starting with analog video and plan to use a battery of analog processing hardware and filters.

On the other hand, anything that starts out digital, and is LOW RESOLUTION, and is poor quality, is pretty much damaged forever. That's basically what we have here. You can try a few things to make it less ugly, but not by too much.
