Hi,
I have capture some old movies from my analogue video cam. I captured using VirtualVCR using the Huffhyv code for compression. Worked great. I now needs to do some cutting to remove stuff that I don't want etc. The target is then to create DVDs out of it.
So I now started to test with VirtualDub to remove some parts and do some filtering (Deinterlacing to start with). But I get a problem. I want to use Huffyuv again when saving the edited files. Everything seems to work fine in VirtualDub, I can save a avi file using that compression. Although when I want to try to play/open the file it both crashes my Windows Explorer and the program I use to open the file. In some way the resulting file is corrupt in one way or another. I made some tests outputting using divx or completely uncompressed format and it works great. It is only with Huffyuv that I get this result. Doesn't matter on which disk I output it, it always ends with a corrupt file that I can open.
Has anyone experienced this problem? I would think the Huffyuv codec should be OK since the captured files from VirtualVCR works perfect when opening and playing them. Could there be a problem to read a Huffyuv compressed file and outputting a Huffyuv compressed file at the same time in VirutalDub??? Heeeeelp!
By the way I should also mention that using direct stream copy for the video stream of course resulted in an OK file so I could do the cutting part. But using the filters I need to go into full processing mode and then a I need to do the compression again when outputting as I understand.
Regards
Micke

Since you can capture using Hufyuv, it appears the codec is properly installed and functioning.
The suspicion could be directed to VirtualDUB. Which version are you using? Possibly a very old version could have a problem.
Next thing to try, is to save a small part of the file (1 minute) using no filters and full processing mode. If that file is also corrupt then you are having a problem with how VirtualDUB uses hufyuv, which would be strange.
Another thing to consider is the deinterlacing. Irelevant of your problem, but don't de-interlace interlaced video. It doesn't work nicely and will produce good results, unless you have a progressive DVD player and a progressive TV, projector or Plasma panel.The more I learn, the more I come to realize how little it is I know. -
First, what version of Huffyuv are you using? If it is 2.2.0, then answer this: are you saying that A)after capturing in Huffyuv, you are then successfully able to open that file in VirtualDub without errors? Or are you saying that B)you can capture using Huffyuv and you are able to resave avi files to Huffyuv in Virtualdub, but are unable to open the resulting Huffyuv avi files again without error? If B is the case, then immediately remove version 2.2.0 and replace it with version 2.1.1. The newer version, in most situations, produces 'files' that are completely unusable. Hope this helps.

Thanks Steen. Yes I were using 2.2.0. And well I guess the answer is yes for both A and B. I can capture compressing with Huffyuv and open in VirtualDub without errors, and then editing and resaving in VirtualDub using Huffyuv again is also done without errors. But then trying to open that output file does not work, it gives an error every time.
I now tested with 2.1.1 and that worked fine. Although then I get a new problem which I guess I have myself to blame to not test all the steps in the chain before capturing a lot of video. I now have one and a half hour of captured video using 2.2.0 which does not work with 2.1.1 so opening my captured videos now only shows garbage since they are compressed with 2.2.0 and I now have 2.1.1. So back to step 1 to do the capturing again but using 2.1.1 this time. Not funny but at least now I know the editing in VirtualDub can be done with the 2.1.1 Huffyuv.
Regarding Deinterlacing SaSi. When I captured I got horisontal effects, mostly when things move in the picture. I searched for answers and found that doing Deinterlacing would solve this. From what I could see watching the output window in VirtualDub it actually makes it better so thats why I thought I had to go with Deinterlacing. Any other suggestions on how to get rid of the horisontal effects? From what I understand they are common in the result of capturing analog input. -
There are many fine articles and tutorials concerning interlaced video and telecined video on this site. You might also want to check Nicky Pages' site ( http://nickyguides.digital-digest.com/ ) and Luke's Video Guide ( http://www.lukesvideo.com/ ) , both of which contain excellent explanations of this topic. If your video is true interlaced video (meaning that each field of each frame represents a unique moment in time), your best bet, IMHO, is to leave the interlacing alone, especially if these files are destined to be played on a tv set. If, however, you are creating files exclusively for viewing on PC's, then you probably would want to use an area-based deinterlacer or a motion-based deinterlacer (like smart deinterlacer). Both are available for VirtualDub. BE FOREWARNED, though, that interlacing is NOT the same as telecining, so do NOT try to, or let anyone convince you to, inverse telecine (IVTC) fully interlaced material. You WILL be sorry.

I have had the same problem just recently. I use the huffyuv codec with IUVCR and then edit the avi file with TMPGEnc and have in the past had no problems. Now, TMPGEnc (and Pinnacle Studio and Express) both "crash" when trying to open any recent captured files. I have tried other codecs with IUVCR and TMPGEnc has no problem so I have decided it is something with the Huffyuv. I am using 2.2.0 and went back to 2.1.1 but still have the problem. I even uninstalled the huffyuv codec and reinstalled to reset any settings that may have been changed causing the problem but no sucess. VirtualDub will read the file and I can edit but when saving with the huffyuv codec - again the file is not usable by other programs.

Kanpoke: without more details (how is vdub set up, what program are you re-opening these files in, etc) I cannot figure out what the problem may be, but it could be that the AVI format output by virtualdub, AVI 2.0 or OpenDML, may not be compatible with some older programs. Also, virtualdub has an AVI 'ceiling' of 4GB (4096KB) on FAT32 systems (on NTFS systems, filesize is limited only by available drive space), which can choke some programs. Try using the "save old format AVI" option and see if that helps.
