best program to resize (larger) dat (VCD) video files

[perfection]

What program should i use that resizes faithfully and with minimum loss (any particular agorithm to be chosen like bicubic or nearest neighbour)l my extracted VCD dayt video files

Shall i retain the dat/mpg 1 format or change format also (which format is best) in the process

any advice or precautions or settings i need to worry about

Thanks

Resize for ??? resolution? What?

You will save in hardisk or other media?

Try avisynth scripts or Virtualdub to resize resolution.

Last time I resized up from VCD to DVD I used VirtualDub and frameserved over to MainConcept.

DGIndex -> AviSynth with NNEDI plugin

Resizing function in NNEDI leaves the existing pixels untouched and inserts interpolated ones for x2 (=VCD2DVD) or x4 size.

I agree nnedi3_rpow2() is probably your best bet. But VCD usually has a lot of macroblocking so you'll want to deblock before upscaling. You can also look into Video Enhancer.

On the other hand, why bother? Most DVD players or HDTVs will do a fair job of upscaling the original VCD. Usually a bicubic filter. Not as good as nnedi3_rpow2() but not a huge difference. DVD players can play the MPEG 1 video from VCD. You just need to convert the audio from 44.1 to 48 KHz.

Except a lot of recent model DVD players, and many BD players, no longer play VCD (though they may still play plain MPEG1 files), so the idea of doing a conversion beforehand may not necessarily be the 2nd choice.

Mpg1 is dvd compliant so no need to convert if you are going to author as dvd video.

Yes, but...
Few authoring programs accept it. I have a test DVD that I made containing only MPEG-1 video (it's at valid resolutions and bit rates for DVD) and I had to use Scenarist to make it. That would not be a realistic option for most of our members.

It would not surprise me if a small number of manufacturers no longer support even valid MPEG-1 in DVDs as I think the only place I ever saw it used was on some Russian DVDs I have where it was used for a short studio logo clip.

Yes, that's what I meant. Leave the video as-is, convert the audio to 48K AC3, author as DVD.

Only a subset of MPEG1 is compliant with DVD. Thankfully, this matches what's proper for VCD.
But from here on out, I'd say it might be smarter to do a conversion to MPEG2 or even better to h.264, for compatibility's sake.

I would agree.

I do quite a few conversions from VCD to 720x480 for DVD. Like already mentioned, nnedi3 is about the best upscaler in the AviSynth world at the moment. And that's after deblocking and noise removal along with other kinds of cleanup of the original crap MPEG-1 file. Then after the resize I'll sharpen.
