overscanning.. help?

[only_emo_kid]

Old analog TV components couldn't precisely size and center an image (not to mention that originally TV's had round picture tubes). Even if you adjusted one of those old TVs so that the picture exactly fit the screen -- you would find that as the components warmed up or cooled off the picture would change size and move around.

So TVs were designed to overscan. They enlarge the picture so that the edges of the image are never visible. It was considered better to lose an variable, but small, amount of picture at the edges than to have a visible black border the moved unpredictably.

I think this has also become a matter of marketing. When the typical consumer goes into a TV store and sees two TVs with identical size screens, but one has a bigger picture (ie, it overscans more) they may be more likely to pick the "bigger" one.

this tv is brand new basically.. I guess its whut u were saying has overscan... I notice with my dvd player on its main screen where it says APEX it only shows half the X (probably overscan) its in the top right corner too.. oh well, Thx

Yep agree with everyone about GUIDES.

A GUIDE is PURELY a GUIDE.....no more no less.......the REAL way is to FIGURE it out yourself....(maybe using a GUIDE as a point of referenece ONLY)...we all do things differently and probably prefer 'our own' way to anyone elses but that is not to say anyone else's method is wrong......holding someones hand is pointless as you need to become comfortable with 'your own' method(s).

There is no DEFINITIVE guide.

Why on earth people are scared of playing around with settings and encoding a couple of minutes of vid (or audio) is beyond me, its the only way you ever figure out anything....and lets face it more and more people are asking for INSTANT SOLUTION (best settings, best encoder, best res, best audio rate etc) but cant be arsed to TRY ANYTHING themselves.

Couldn't agree more. That is how I learnt also. The following is not aimed at anyone in particular - just a general observation. Everyone was a noob at some point, but I would be very confident in saying that the most knowledgable people on this site learnt by reading and experimenting - seeing what worked for them. You only get out what you put in, and if you're not prepared to undertake a bit of research, try a few things and/or make a few mistakes (and coasters) along the way, you're never gonna learn anything.

Far too many people buy their DVD Recorder or burner and think video is a mindless task. Well, here's a newsflash - it ain't.

There was a guy called "ElmarK" on here who had his own website and a little program he wrote himself called (S)VCD design helper. The purpose of (S)VCD design helper was to do all the calculations for you with regard the resizing for TV overscan allowance. It also included a very accurate bitrate calculator as well.

ElmarK is no longer around and I think his website has disappeared which is a shame because it was by far the most useful little app I've ever found. Anyway, I have liased with "Elmark" and modified his program significantly. I have tweaked the bitrate calculator and improved the program to do the overscan calculations for VCD, CVD & SVCD in both PAL & NTSC sizes. I can't host it because I have no webspace of my own, but if anyone thinks this might be useful and can host it for others then I'm happy to let someone else have a copy. Here's a screen cap of what it looks like:



It's designed for the TMPGEnc Plus user specifically since that's what I use, but I'm sure the same information could be interpolated and user in the other encoders as well. There is an accompanying TMPGEnc Tips encoding setup PDF file for it as well.

Dude you can't even figure out FitCD and now you offer to host a program that does the same?

*sigh*

dude wanted it hosted. so, i'm helping him out?

Sent. It's 167.9KB compressed with ACE including the PDF file of TMPGEnc tips document. If Baldrick is reading this, it might be nice if VideoHelp.com themselves could host this? Any chance?

You could always try and PM him. I would if I were you.

Highly unlikely I'd say. My experience of yousendit links are that they barely last 24hrs at best. Downloading from yousendit is like jumping on a moving train - very frequently unsuccessful. You said *you* had a site that could host it. Clearly that was not the truth.

I thought that's what this site was all about.

.. okay? i was only trying to help

Sorry, I meant to add: since they started that way that is the way they still work.
