VHS to MPG Converted file To HD Quality

[ConverterCrazy]

Hello,

I got a VHS tape converted by a commercial vendor [not a professional].

The quality of video doesn't look good.

Is it possible to convert it to high quality video in some other format?

A step-by-step guide will be helpful.

The file info is as under:

I forget the precise term right now but 480*576 was a schema used by broadcasters to allow for a reduced bitrate. I did not think that was even possible directly as a capture medium.

Now add to that your picture-in-picture (I must assume that was there on the original tape/broadcast) and you have an even smaller video frame.


So combine that low bitrate - can not improve quality by throwing more at it - plus the smaller frame - which will look even worse if upscaled - you are in a lose lose situation.

In your player turn Deinterlace: ON, and it will immediately look much better

Is it possible to convert it to high quality video in some other format?

Yes, By recapturing the VHS tape in a better VCR with a better capturing workflow.

Low bitrate, low resolution (480px), dropped frames.
It can be improved a bit, but it's just poor digitization quality.

Thank you all.

With deinterlace ON, it looks better.

Using another VHS player is impossible. Nobody I know has it. I got the digitization done at a small commercial shop.

The MP4 sample looks good. I will experiment with Avisynth script to deal with blooming in certain scenes and use sharpen. Deinterlace? Yes, that too.

The bigger problem is small frame size in the original.
