bad frames

[cava99]

im trying to convert a an svcd mpeg to a dvd compliant mpeg

i have extracted the mpeg file using iso buster the file plays fine on any video software

how ever when convert it at a certain point in the film it freezes at a certain frame

i downloaded several versions of virtual dub and in each version when i try to open the mpeg file i ge this error

"Mpeg import filter : pack synchronization error"

im trying to fix this bad frame if this software doesnt work or cant work for me could any body give me some suggestions?

[likwid8]

you should try fixing the SVCD first and then conver it to DVD mpeg... if it happends during the conversion then try using a diff encoder, like CCE

[cava99]

i dont have thos svcd's anymore just the converted files is there anyway of fixing or taking the bad frames out?

[Dragonsf]

If you don't have the original SVCDs anymore, what do you have now (on HD) ?
A mpeg file in SVCD-Format?if so, can you use AViSynth?Open the file with the mpeg-filter and try to frameserve.Such way, you can delete the bad frames very easy.

[cava99]

ok ii downloaded svi synth but when i install there is now .exe to open the programme all i have in the folder is some htnl pages and an uninstall .exe does anyone know of any other programmes to help me with bad frame editing ??? please reply asap

You have to copy the file avisynth.dll into your Windows/system32 directory and apply the registration by double click on avisynth.reg.
Here:
http://www.avisynth.org/index.php?page=YourFirstScript
you find a beginner's script.

c=DirectShowSource("myclip.mpg")
f=1234 #your 1st bad frame
c.deleteframe(f).duplicateframe(f-1)
f=4567 #your 2nd bad frame
c.deleteframe(f).duplicateframe(f-1)
.
.
.
return c

Put this into a text file myclip.avs and open that file with VDub.

instead of DirectShowSource, you can use the MpegDecoder:
http://nic.dnsalias.com/MPEGDecoder.html

LoadPlugin("C:\MPEGdecoder.dll")
MpegSource("C:\myclip.mpg")
.....

BTW:what version of avisynth do you want to use?

Depending on the problem, a simple pass through VCDGear may fix your problem. You can find it in the tools section. Make sure you turn off the SPLIT setting in the options, and turn on the 'fix mpeg errors'. It won't work miracles, but it will correct some issues, which may also be causing your problem. At worst, you've wasted 2 minutes trying

Just select 'MPEG to MPEG', and browse to your source file. It will then prompt you for a new file name.

Dragonsf, new versions of AVISynth just use a standard setup.exe, not the old registration patch methods. 8) You just run the setup, and install it like any old piece of software.

[Dragonsf]

yes, you're right, but only the old version works with Premiere (as avs plugin).Or is there a newer version?

i tried using vcd gear i did wat u said djgrumpy but it just freezes at an ealier point i thkn its going to have to be fixed through some video editing software right. about avisynth i have downloaded it and installed it but what i want to klnow is, is avisynth and actual programme or is it a plug in of some sort becuse there is no luanch file for it

ne idea's?

and any idea's why these mpeg files dont open up in virtualdub?

[Dragonsf]

Avisynth is a sort of codec.If you open an avi ending .avs, the dll will be loaded and the avs will be interpreted.If everything goes right, you'll get you frames uncompressed.
Vdub can't normally open mpegs, only the modded VDub can.
Looks like you mpeg stream is somehow corrupted.

[cava99]

dragon ok firsstly can i talk to u on msn messenger i would really appreciate your help and could you walk me though sorting this mpeg issue out

is there any other software that can help me?

[DJRumpy]

Your almost there, if you have it installed. AVISynth is a frameserver. What it does, is open your source file (MPEG or AVI), and serve it to any encoder that supports it, like TMPGenc, CCE, or MainConcept.

What version of AVISynth did you install? Also, just to verify, your source file is AVI? If it is, open NOTEPAD, and type the following:

AVISource("c:\folder\video.avi") #put the right folder\filename here

Save the file as VIDEO.AVS. Drop the VIDEO.AVS file onto meda player. It should play as if it was the original AVI itself. Frameserving like this will often get around corrupt/bad frames in a source file. Just open the .AVS file in whatever encoder you use.

I presume from the previous post, that he ripped a mpeg-2 from a SVCD to HD.So IMHO he starts with a mpeg.

[cava99]

wat im actually looking to do is burn it on to a dvd so really wat im looking to do is reair it???

any suggestions

[DJRumpy]

That's what we're attempting to show you. If your source file is still MPEG, then you will also need MPEG2DEC for AVISynth versions 1.0 - 2.0, or MPEG2DEC3 for AVISynth versions 2.5 and greater. Place the DLL in your AVISynth plugin directory (Usually C:\Program Files\AVISynth\Plugins )

Your script would look like this:

Mpeg2Source("c:\folder\video.d2v") #put the right folder\filename here

You have to open the original SVCD MPEG in DVD2AVI, and save it as a project file ( FILE | SAVE PROJECT ). Download DVD2AVI version 1.76 from www.doom9.org
