Is there a tool to resize MPEG2 to MPEG2?

[Chips]

I've looked through these forums and perhaps I've missed it, but I can't see how I can easily do this.

I need to resize some perfectly good MPEG2 material at a 544x576 resolution and output it to 720x576. All I need changing is the resolution. No filters, effects, or other processing is required. I'd have thought this was fairly simple. Is there a tool out there that does this in a one-pass job?

Thanks,
Chips.

Thught about this for a few minutes; And decided to give a blunt anwer. First I'll tell you why:

What have you done yourself to find a solution, what have you searched for and what did you come up with/what tools have you looked at.

I get the feeling that you havent searched well, and just thrown the question here.

The answer to your question is talked about in many ways on this entire forum, and there are many ways to do this (but not allways in 1-pass !).

So the blunt answer will have to be: :search:

Well, I'll tell you honestly that I have been searching solidly on these forums and elsewhere for the past three hours. I've downloaded VirtualDub MPEG, ffMpeg, DVDPatcher and QuENC. None of them did the job as far as I could tell. The obvious one is TMPEGEnc but I haven't tried as I understand it's not freeware, but maybe that's the best option, I don't know. If it works then I'm quite prepared to buy it.

Also, looking around extensively, I get the impression that most people are converting from one format to another, that's why I'm not seeming to end up with an answer to my specific question. I don't want to convert to AVI and back again, as someone suggested elsewhere.

So, I feel I've given the search a good go at least. The last thing I wanted to do was to wade in with this question without researching it first, believe me.

you have to reencode your content if you want to change the resolution.

for this job i'd recommend the following workflow:
index with dgindex => resize with avisynth => HCenc => Mux with IFOEdit => DVD

It sounds possibly like you may be changing to dvd resolution from a TV capture? (I could be totally wrong of course!)
You may not need to re-encode if that's the case. Check out step 3 in this guide:

If I'm totally wrong about what you want then I'd personally go with the workflow suggested by ToS_Maverick, possibly replacing IFOEdit with Muxman.

Thanks ToS_Maverick and Mr_Odwin.

ToS_Maverick, I'll bear that sequence in mind, although I was rather hoping for fewer steps. But if needs must...

Mr_Odwin, you guessed right. They are indeed TV captures. I live in PAL land and they are from DVB-T transmissions. Unfortunately they need converting to the higher resolution before they can be written to DVD, but I guess you knew that already.

I looked at DVDPatcher and tried to do exactly what it describes. Unfortunately, the DVD authoring software doesn't seem to like the file after that and displays it as a corrupted thumbnail in the editing screen. It also stutters and jumps around the screen in DVD Preview mode (I'm using Sony DVD Architect, btw). However, what I hadn't tried to do was to then burn this to DVD. Whaddya know? I burned it to a RW and played it - and it looks OK!

This was only with a small sample file, but I shall try a larger one and post back FYI. What I don't know is whether all DVD players will then play this DVD, or whether some will balk at the 'hacked' header.

Thanks for your help,
Chips.

PS: I notice that TMPGEnc is in fact Freeware - my mistake. I was under the impression that it watermarked the output in some way, unless purchased. :o

Hi!They are indeed TV captures. I live in PAL land and they are from DVB-T transmissions. Unfortunately they need converting to the higher resolution before they can be written to DVDA "one click" freeware solution would be to use "DVD Flick"...

[Chips]

Well, I burned a full DVD last night with 4 x 1 hour programs, 3 of which had been 'DVD Patched' to 704x576. My trusty Sony DVD player played them all without a hitch. I need to try the DVD on a couple more makes of player to be sure, but this looks like the solution I've been after - and no re-encoding required!

Thanks one and all for your help,
Chips.

PS: Thanks setarip_old, I had a look at DVD Flick and I'll bear it in mind if I ever come unstuck with DVD Architect.

DVD Styler is very flexible (and free) authoring tool. You can even burn DVD using VCD and SVCD MPEG files (after slight containter correction in VCDGear) without re-encoding. And such DVDs are perfectly playable on both my standalone DVD Player and Recorder.

If You need to re-encode MPEG (and to do it fast:D) You can use AviDemux. It is something like VirtualDub with many codecs built-in, and it works perfectly with MPEG (and VOB) files too. Its a shame it hasnt got HCEnc:/ (but at least it has Aften AC3).
