Svcd to Avi?

Ok, i'm trying to convert an Svcd to DivX because i can't stand any (x)vcd but i'm not sure if i'm doing it right. I've tried the guide on doom9 and it never works out for me so i tried using Dr.DivX and it worked but i don't know if my specs are right or need tweaking so i'm hoping one of you guys can give me a hand. This is the specs...

Now i read under the post of Willard Spud and Polityk talking about framerates shouldn't be 29.97. Is that also correct for this? If so please explain how to correct anything i did wrong here.

29.97fps is for pure NTSC TV/Camera only. Anything shot with a tv camera, or many home cameras will be @ a framerate of 29.97fps.

However, this is not for cinema movies! Even if the DVD reports 29fps, this is incorrect, the actual content 99 times out of a 100 is infact 23fps. What you have to do is either, when using DVD2AVI, ensure FORCEFILM is checked if you get "FILM 96%" or above. This means that you have a mixed content dvd, but the vast majority is at 23fps. If you can't forcefilm, then you must use a process known as IVTC to give the movie its correct framerate!

The reason for this is because if you encode a 23fps movie at 29fps you are wasting a hell of a lot of video bandwidth and the quality of your encode is significantly reduced. What happens is there simply isn't 29fps, yet you've set it to record 29fps, so what it does is simply copy extra frames to fill up the extra fps. This is an awful waste of data, and means your encode will look poor. It may also artificially introduce ghosting and other nasty things.

URGENT ADVICE: don't use dr. divx :lol:

You'll get much better results if you use doom9.org guides. Don't think about what it says, just do it :lol:

It really isn't very hard to follow the gknot guide (although for SVCD re-encodes I've never used it), and if you need any help, then just ask. But I'm not impressed with dr. divx at all.

On the specs, your resolution is too small and you should use VBR audio. Try using Xvid over Divx too

The doom9 guides cover correctly encoding NTSC material so it will be at the proper framerate.

Exceptions that may be pure 29fps:
TV Movies (less and less so, most use proper cameras now)
Home Video
Very Low budget shot on home video cameras.

Ok, i will try doom9's guide again and see if i can get it to work out. I know a lot of guys don't recommend Dr.DivX but it's the only one that i ever got it to work out(or so i thought). Re-encoding is a fucking pain in the ass!

I've only ever done one SVCD encode myself, that was using Nandub :lol:

ThEdEaDLiVe · **Posted:** Mon Sep 06, 2004 9:39 pm **Post subject:**

Now i keep getting this error everytime with virtualdub "An out-of-bounds memory access (access violation) occurred in module 'ntdll'." It happens at the same spot everytime.

Well i give up with this because Vdub keeps crashing. I think i might just upload it the way i did it with Dr.DivX unless i can find another way to re-encode it without using Vdub.

Polityk · **Posted:** Tue Sep 07, 2004 4:12 am **Post subject:**

You may try nandub, perhaps it will handle the problem better. If you really must use automatic tools, try AutoGK, although it uses virtual dub too, so it probably won't solve your problem.

I don't know why people insist on those inventions like DrDivx etc, they produce mediocre results because they cannot be tweaked... Those doom9 guides really aren't that hard to follow! The only thing with GK is that sometimes the sound in multiple audio rips can be slightly desynced, that's why I always mux my rips manually.

Trust me i would rather do it the way you guys do it but it never works out. I just was going to use Dr.DivX because it's the only thing i've used that's encoded the file without crashing. I don't want to use it because i know everybody says it sucks.

But if i can substitute Nandub i'll try that. I got no problems following the guide on doom9 but it's the software that's not working out for me. Do you know what that error is i mentioned above with Vdub?

Guess what, some people seem to have similar problems:

Use google to find more, perhaps you'll find your solution somewhere. Good luck.

Ahhhhhhhhhhhhhhhhhhh!!!!!!!!!!!!!!!!!!!!! Now with Nandub i get an error when i try to load the Svcd into it ---> mpeg import filter pack synchronization error. Do you guys think maybe the Svcd is corrupt? I've tried doing the google thing with both these errors and i'm not getting anywhere. With the Vdub error i had read that one guy got it to work after he upgraded to XP SP2. So yesterday i upgraded and still the same error. I tried XviD and DivX but they both ended up with the same thing. Do you think if i tried uninstalling all my codecs and reinstalling them that would help? I've been using the Kazaalite Codec Pack. Or do you think it's just a software issue?

Polityk · **Posted:** Wed Sep 08, 2004 12:48 am **Post subject:**

Don't use Kazaalite Codec Pack. Use GK Codec Pack.

Ok. Thanks for the quick response :beerchug:

Will see if that helps. I'm fucking bound and determined to get this right even if it kills me :suicide:

I think i got it now guys. Does this look ok...

It looks a little pixelated but i think that's just from re-encoding an encode, no? But after uninstalling all codecs on my computer, ffdshow, gordian knot, autogk, and some other crap and starting fresh Vdub still crashes but it's only after it finishes doing a pass. So i just clicked ok when the error came up and it would start the second pass and at the end would crash again but still encoded fine. Or i guess you'll let me know...

Looks good to me. Like you said, it's a re-encode job, quality can't be as good as the source.

Polityk · **Posted:** Thu Sep 09, 2004 2:12 pm **Post subject:**

Looks fine to me.

Ok. Thanks for all the help guys. Will do cd2 and hopefully have it ready for upping tonight.

ThEdEaDLiVe · **Posted:** Sat Sep 11, 2004 2:11 am **Post subject:**

I noticed with my re-encode of the 2nd half that it always comes out oversized slightly. I tried twice and the second time i used 0.188 bits/(Pixel*Frame) and it came out at 361mb but the first half came out as 351mb. Now i was just going to cut off some of the end credits to make it 350mb but is that the wrong approach? Should i be able to always get 700mb altogether without cutting some of the credits?

spudthedestroyer · **Posted:** Sat Sep 11, 2004 2:21 am **Post subject:**

aren't you muxing together the movie, since if its a multiple cd SVCD, lengths will be different, and you'll get a more accurate result if you work from a single source.

TMPGenc can join mpgs easily i believe

ThEdEaDLiVe · **Posted:** Sat Sep 11, 2004 2:33 am **Post subject:**

Ahhh, i see. Join the 2 Svcd's togethor before encoding. Shit, why didn't you say that before? Now i gotta start all over again :cry:

Just kidding dude. Thanks for all your help once again.

Svcd to Avi?
