Hi,
I'm trying do copy my old VHS tapes to DVD and I'm using VDUB to capture the movie, a brief list of hardware:
1. rather strong laptop (i7),
2. empty e-sata hdd,
3. panasonic NV-HS1000 VCR (with TBC enabled),
4. Pinnacle MovieBox HD (Pinnacle 510-USB) capture card.
I've been doing some tests (capturing, filtering, etc). After I've learned everything (and prepared a list of filters I'll use) I've decided to dump my whole VHS tape. And the problem began 
I'm capturing the video without any big problems (91 inserted frames for 30minutes of video stream, usually on some "cracky" scene changes). But I'm not able to capture whole tape at once, because in the random time periods something wrong happens and the VDUB starts to insert a big number of null-frames. For example I have 100 "frames inserted" for 40 minutes of video and suddenly the number increases rapidly. The only thing can be done is just to stop capture. When I start recording once again - it works like a charm (in the same video moment it was broken before).
I have disabled all software I could, the disk does not produce any noise (and the head is not searching for anything).
The problem starts in random time periods (sometimes after 7 minutes, sometimes after 40). It goes clearly and suddenly - OMG "frames inserted" number rises to 1000 and still grows up.
I'm using Huffyuv 2.1.1 and no audio compression. All video filters are disabled, audio and video playback also.
Maybe you'll have some ideas and hints. Where is the problem?
Thanks in advance. |

In VirtualDub capturing modus:
- click the Capture menu and choose Timing...
- uncheck all the boxes and click OK
Now try once again ... |

Thanks for your answer, indeed this is great way to have "0" null frames inserted.
However I'll finish with video/audio desync... (I've tried)

When you look in File > Information... for the recorded video, do you have too less video or too less audio (for the given time period) ?
Probably there is something that is suddenly taking up cpu- and or disk-resources at a given time.
(Who knows, it can be your virusscan or maybe the Microsoft Windows Update process ...)
Maybe you can once run Sysinternals Process Explorer while capturing video, and look which process is taking up resources when frame rate is suddenly slowing down.

I believe there is no simple answer to this problem... but I think I've dealt with it.
First of all I've modified disk I/O properties (increased chunks in buffer from 2 to 128 creating total buffer with 65MBytes). This almost solved the problem  Unfortunatelly my VCR is rather worn-out and sometimes video-head loses synchronisation and the video is completely broken (black/white stripes). Then I must search for some scene-changes before desynchronisation and start dumping once again from this moment (to join the parts in VDUB afterwards). There is nothing I can do with that unfortunately.
So the short answer would be to change the I/O properties in such case and it should help.
Does it make any sense? Or it was only the lucky coincidence?

I'll check it today, but my CPU is used in 6-15% during dumping process, so I'm not expecting to find any critical info

I'll check it when this happen again, I'm not sure in this moment, but because I've checked "sync audio to video... timing option" the audio track was slowed down to meet the video sync and in this moment any speech is like a maaaaaarssssiiiaaaaaannn UUUUUFFFOOOOOOOOOOO

From the last minute, I've:
1. disabled all software running I could,
2. disabled WiFi,
3. disabled AntiVirus,
4. disabled SQL Server,
...and voila - whole VHS is on my HDD, 3 hours with 100-200 "frames inserted". Hope this thread would help someone.
Thanks for your attention and help! |
