Files don't fit on a CD!?

[joncom11]

Ok, now I've got a wierd situation... I've been encoding an anime series for my brother, and burning two episodes per disc. When in the project wizard, it predicts what bitrate I can use to fill 50% of a 700MB SVCD disc... I use that bitrate, and encode my video. The file size usually comes out to 390MB. Although, 2 x 390 = more than 700... it seemed to add to the disc and burn the SVCD fine (using Nero).

I took about a 3 month break from encoding the series, and formatted the computer etc, so I had to reinstall TMPGenc and didn't have my saved settings that I used for encoding. I used the same method, to select the bit rate, etc... and started encoding new files from the anime series... the .mpg output files are about 390MB also. The thing is, now when I try to add these to a Nero SVCD project, it says that it fills WAY to much of the disc (775MB) as apose to the other ones I used to do that were BELOW 700MB.

I still have a couple of the old .mpg files from before and I don't understand why files that are the same size, wont both fit onto a disc.. (in fact: the newer encodes I'm doing as actually a bit smaller!!)...

I'm really confused, I hope someone can tell me what's up or how to fix this... thanks

Try this, it MIGHT work.

1- In Nero, Click on:
File->Preferences->Expert features
and select Enable Overburn.

2- When all is ready in Nero and just after you click on the "burn" button, click on the Video CD tab, and UN-select "Create Standard Compliant CD"

Make sure ur using Cd's with 700mb capacity when you burning ur SVCD's. And always use a CD-RW to test first (cuase if it dont work, u can always erase it and try something else, and u wont be wasting blank CD's)

Hope this helps

As long as you are using the VCD or SVCD templates in Nero there is shouldn't be a problem with fitting up to 795mb on one 700 CD without using overburn.

That's what I thought too.... even if I take two older encodes (.mpg) and put it on the template, it fits, but if I use the same template but with my new encodes (.mpg) it doesn't work!

[teegee420]

Describe the specs of your new encodes. Perhaps they're not standard compliant.

[joncom11]

They aren't.... but the old encodes weren't standard compliant either. See, I encode my SVCD's at 640x480, since nero just makes them that resolution when creating the SVCD anyways (works on every player I've ever tried.)...

Just going down the lists and tabs in TMPGenc, those are my settings for the encode... the file is about 23min

Well that will cause probs straight away
std ntsc SVcd should be 480x480 .. also use 2 pass vbr with hi of 2500, avg 1600, low of 300 and this should make the files a lot smaller with no loss in quality..

[joncom11]

shouldn't the filesize still be the same no matter what resolution you do it at, since it only puts out the set bitrate anyways? if u have 800x600 video at 2000bitrate... and 400x300 video at 2000bitrate.. wouldn't they come out to same size?

[teegee420]

They should yes, but why are you using non-standard resolutions? You should stick with 480x480.

[joncom11]

because my source file is 640x480 and if i encode it at that, it fits the screen perfectly without having letterbox effect on vertical OR horizontal.... and i don't have to cut anything off.

You are SO clueless you haven't a clue as to the concepts behind WHAT it is you are DOING.

i know.. i'm quite arrogant in this field.. but i'm just going off the little experience i have and what worked best... how can i convert a file form 640x480 without losing quality? i'm losing 160 pixels in width... plus it gives me black bars either on the horizontals, or verticals...

[teegee420]

how can i convert a file form 640x480 without losing quality?

You can't. Use a decent bitrate and the quality loss won't be too bad. Why don't you use the original source file instead of your created mpeg?

i'm losing 160 pixels in width... plus it gives me black bars either on the horizontals, or verticals...

Have you actually tried this or are you just speculating? Your DVD player should stretch the 480x480 video to fill the screen.

letterbox has nothing to do with 640x480 or 480x480 or whatever.
if you convert any video to some standard resolution, you should always keep the aspect ratio (unless maybe when you create a 16:9 video). if black bars appear, they do cos they're needed. you may ofcourse remove them, but you should never stretch!

You got 480 lines vertical so you'll have plenty of quality. 352, 480, 640, 720, whatever. The horizontal is going to be stretched to fit your screen regardless. All you are accomplishing with using the 640 horizontal is quality loss because you're needlessly wasting your available bitrate. If you're going to deviate from the SVCD standard, go smaller with the 352 horizontal, you'll get a better picture because you're encoding less with the same bitrate.
