Why do I get this static ?
I am at the very first step of using Avisynth i.e. opening an .avi file. I set up my test.avs with just 1 line in it avisource("myfile.avi") and got the message "Couldn't locate decompressor for fourcc dvsd". Windows medial player otherwise was able to open the file with no problem but not through the script. I, somehow managed to open it by searching and reading and installing Panasonic DV Codec. Now, I can open the file and it plays it but I get static this static screen every 2-3 seconds:
Any help greatly appreciated... Thanks. Subhash. |

?? no, avis should be opened via avisource, why directshowsource??
and why should he install ffdshow, as all that is/ was missing is a DV decoder... Subhash already found out that a DV codec is missing and installed Panasonic DV codec - so far so good... @Subhash I'd recommend another DV codec - I can't see your picture as it is not approved by now and I don't know what you mean by saying 'static' - but as I said, try another DV codec. I'd recommend Cedocida DV Codec by A. Dittrich. It is free and open source and supports PAL and NTSC and a variety of in- and output formats... please un-install your Panasonic DV codec and install Cedocida and report back... / Sill Edit: windows does offer a Microsoft DV codec out of the box - that's the one used by WMP... and that makes me curious why avisynth wasn't able to decode your DV file... hmm, probably because Microsoft's DV codec isn't registered as VFW

Exactly.
I tried loading up some DV AVIs that played in premiere just fine the other day. Drag and drop to VirtualDub complained that no VFW decoder was available. Of course... Cedocida is nice ~MiSfit

Looks like a problem with the colorspace, 4:2:2 Planar ?
Edit. I could be wrong. Maybe the wrong type of codec is trying to decode something it's not supposed to Last edited by Terranigma; 12th March 2007 at 00:02. Reason: correction |

Thank you all for your replies. As I said in my previous post, I get this every 2or 3 seconds. Here is the good frame from beginning of the same clip that I posted before.
If it was the codec problem, then it wouldn't play at all. Right ? I will try installing Cedocida and see what happens. Thanks... |

Actually, try encoding a x264 file to .avi, and change the fourcc to xvid. It won't play correctly. You'd only get a black screen with the video's resolution and audio if it has any audio.
I can't really help you here as i've never experienced anything like this. foxyshadis any incite? I can sense your presence. I'm a fox after all Last edited by Terranigma; 12th March 2007 at 00:28. |

maybe something went wrong during transfer - I don't know. But before making any false assumptions please test out Cedocida. as it turns out this isn't an avisynth issue - this thread should be moved to the DV sub-forum as it will get a wider audiance

OK. I uninstalled Panasonic DV Codec and installed cedocida. Made no difference. I transferred the video with Windv which I understand makes a direct copy from the tape to the hard drive. I have tried couple of other clips also transferred the same way and all give the same results.
What else can I try ? |

how did you configure WinDV ? for type-1 or type-2 avis?
I don't know if that makes a difference but it's worth a try... and I remember to split up the DV capture into 20min pieces and join them afterwards...

Does it work in anything else? At this point there's strong evidence that it's just corrupted, either on the tape or during transfer. Try retransfering. Otherwise you might need to maually remove the bad frames, and maybe check out your camera for causing corruption.

I could clip 1 minute from my capture and send it to someone more knowledgable but filesize is going to be a problem. Even 1 minute avi is going to be about 200 MB. Any suggestions ?? Thanks. Subhash. |

I don't know how else we can try to address this issue. I am still stuck at the first step whereas I have a long way to go having to remove noise from the avi files using its filters but I am still at square 1. Any other ideas please ? Thanks. Subhash. |
