Well, let me put it this way. Compatibility mode works fantastic. The audio is never out of sync, and as long as I keep the recording under 2 gigs, it works great. I use the huffyuv codec, etc.
The problem is, most of my recordings are well over 2GB. I know that the VDub site says, any recordings in (compatibility mode) over 2GB will not function. Well, they ofcourse do not. I can't open the 2+ gig file in Vdub, or any other application. I REALLY want to know if there is some way around this.
Everytime i try the normal F6 capture mode, the audio gets really out of sync, codec or no codec, etc.etc. I've tried everything. I've messed with many various settings, with no real luck. So I stick with compatibility mode, which ofcourse works great, until it passes 2GB and I try to open it to edit it. It says it does not recognize the file type.
So is there possibly some way around the compatibility mode 2GB limit? Why is there a 2GB limit anyway? What causes this restriction?
thanks for any help |

Compatibility mode leaves the entire writing of the AVI file to the the AVICap routines built into Windows. Unfortunately, this module simply cannot write AVI files larger than 2GB, period.

I have a small feature request regarding the filesize so I'll put it here. Could the spill drive option be tweaked so that the filesize wouldn't have to be less than 2GB? I have two NTFS drives I could use for capturing but the 2GB limit per segment doesn't appeal to me 
Or have I missed something (once again) ? |

ok
im just plain having problems trying to get this audio to sync in normal F6 mode. Works fine in compatibility mode, as it drops more frames, which is fine by me. But in F6 mode, it drops barely any frames but audio is out of sync
this is frustrating |

hear,hear!
i want 4gb limit as i'm on fat32.
capuser, have you tried different 'resync mode' options in capture->timing panel?
the 2nd option should drop some frames for you.
1st one won't drop, but you may end up with weird fps rates.

i honestly didnt even realize vdubmod had some capture enhancements, i just always used it for audio purposes.....
thanks for bringing that up as it seems to be working alright now. All I originally wanted vdub to do, was to drop frames in normal F6 capture mode, not just F5 compatible mode, and in vdubmod it seems to do exactly that. Out of 50,000 frames, i lose about 1,800, which really isnt bad at all imo, considering the audio is now in sync.
thanks for that
i have one more rather simple question:
in the rocky snapshot below, you can see the faint diagonal line patterns in the darkened areas......i'm recording via YUY2 @ 352x240 29.97, and these lines are noticable during fullscreen. I've gotten rid of them before by re-encoding (while I record) with huffyuv, but this time they dont seem to go away.
Any ideas?

rocky is a big man, he deserves 720x480, no less!
i never suggested you should capture via vdubmod; try 1.6.4, or latest stable release of 1.5.10.
or the one from my signature which has a timer too.
if there's plenty of motion is video, then even 1 drop is too much. and i guess rocky is not just standing there.
hehe
if you have a constant audio offset(same offset on the beggining and at the end of the file) then use audio->interleaving to bring it back.
interference on the dark areas only?
pretty weird: do you see it in source vhs too?

well, im on a celeron 1.4, and my hardware does zero work, so, after 352x240 it gets pretty retarded
on another forum someone suggested vdubmod, and you mentioned the 3 timing panel options, which i only see in vdubmod, so thats how i came up with the vdumbmod stuff.
i dunno, its pretty frustrating cuz im limited due to my comp specs |

Something is really wrong here, because you have way more CPU power than needed even for full-frame 720x480 YUY2 -> Huffyuv. In fact, with a Celeron 1.5 you should be at less than 50% CPU. Make sure you don't have any unnecessary filtering modes enabled in VirtualDub itself, and enable directdraw acceleration (preview accel in 1.6.1+) if you can, as it will make a big difference in CPU usage if you have the preview display enabled.

well, hmm
my processor IS only at 15-20% when recording......
but anytime I go above 352x240, I drop frames like crazy...... Not just in Vdub, but other recording applications as well....... |

I do know I should mention that I am using a plextor PX-AV100U USB 2.0 device to capture everything. Not the best, I know, but it should be able to ATLEAST provide perfect 352x240 recordings. I am using S-Video in, composite audio in, and the audio goes from the capture device to the line-in on my soundcard.
Here is everything im doing, maybe something is wrong.....
so I open up Vdub.....
I go to capture avi.....
Audio - compression, i select CD Quality - 44.100 16bit stereo 172 kb/s
Video - Preview Usually off
Video - Compression - None or Huffyuv
Video - Cropping, Noise Filter, Noise/Vertical Reduction, Squish Luminance - all unchecked
Video - Set Custom Format - 352x240 YUY2
Video - Filters - None
Video - Enable RGB Filtering - Unchecked
Capture - Capture Settings - (capture audio checked) - Frame rate: 29.9697 - Drop % limit - 10, Maximum Index Entries = 32,4000, Video Buffer Limit = 10, Audio Buffer Limit = 4, Audio Buffer Size = 0, Lock Video Stream to audio - checked
Capture - Preferences - Default Capture Driver = Driver 0 - Microsoft WDM Image Capture (Win32)....... "Change Driver settings for: Driver 0 - Microsoft WDM Image Capture (Win32), Overlay checked, nothing else checked
Capture - Stop Conditions = Nothing checked
Capture - Timing - Checked (adjust video clock dynamically)
Capture - Disk I/O - 512/2
Capture Drives - nothing in there
Only thing checked below that is "show information panel", and Enable DirectDraw is checked for Both Fields
whew, hope that helps some |

Have you updated your chipset drivers to the latest version? That's very important with USB2.0 devices in question. You could also try raising the video and audio buffers.
Do you have any other capture devices in the list? |

yeah, to my knowledge all drivers are up to date.......
raised the audio/video buffers, didnt seem to help
im wondering about my controller card a bit........I have a maxtor 4 port usb 2.0 to PCI hub.......and well, with any video capturing device I connected to it, i'd get a stop error (the maxtor drivers worked fine with anything else, it didnt like capture hardware though)........so I finally just diverted to using the standard microsoft usb 2.0 drivers for the hub...... and there are no driver updates on the maxtor site for it.......

Do you have any other USB devices attached to the hub? Does your motherboard have any USB ports you could use?
Maybe you should report the stop error code to Maxtor, they might have some ideas (strongly suspected though  ), or maybe they've got a beta driver hidden somewhere. |

yeah but none of them are on...... I got an external HDD (thats powered off) and a digi cam (with no digi cam attached), and no other 2.0 ports on the system, just these 4
so basically you guys are saying......
on a Celeron 1.4, 384MB RAM, USB 2.0 capture system, i should be getting captures HIGHER than 352x240 with little to no frame drops? I just want to confirm this is abnormal. As i'm not 100% sure, though I imagine I should be having no problems with 640x480. |
