Greetings!

I've had some problems recently with some of the AVI files that are saved when UFOCapture records an event.

About every 3rd event produces an avi that wont play properly. the file size seems right but when I attempt to play the video file it locks up the viewer.
In UFOCapture itself the video only is able to show 2 or 3 frames.
I've changed video capture hardware and even moved everything to a new PC
but the problem remains.

I've attached an avi that exhibits this error.

Can you offer any suggestions?
Thank you in advance!!
Kevin Palivec

Hi kevinp, welcome.

It seems the AVI file is broken (not written correctly).
I have experienced similar things.
It happened when the writing to HDD could not catch up the input stream speed.

There are many possibilities.
1. Other tasks bother or delay the writing to HDD.
-- Unti virus check
-- Shadow back up of Windows Vista
-- System paging or other tasks.
2. HDD writing speed is not enough.
3. Data trandfer bandwidth of PC is not enough.

I am recommending below.
1. Use inner fast HDD > 7200rpm. (external disks are usually very slow)
2. Stop other tasks that may use the drive. Especially untivirus check at the creation or writing of a file, Shadow copy of Vista .....
3. Target drive should be dedicated drive, not include system paging file or system files.

I need information to advice more. What are your OS, CPU, HDD, capture device? Is it laptop or notebook PC?

Hi Kevin
Thank you for info.
Your PC seems good enough. It may not be the reason.
There are many users who uses weaker PC than yours.

There may be some reason that bother the HDD. Such as ...
1. HDD auto power off setting (Control Panel > Power option)
2. Security soft setting (check at file creation or writing)
HDD deflag of the target drive is sometime effective.

I'm not sure though there might be other reasons.
Old HDD that has defect sector runs very slowly....

Thank you for your insight!

Based on your suggestions I'm going to try the following to see if I can eliminate thge problem or at least alter it to see if it's the drive itself or something other than the drive causeing the error. (I have a suspicion it might be the capture card).

I've Re-Partitioned the drive and formatted it with a larger allocation unit.
My hope is that this will allow the drive to save files in larger blocks and thus mitigate the head access times on the drive.

Hello to everybody Smile

I have exactly the same problem you Kevin are mentioning at the beginning.
I have a Samsung laptop, i7, 8Gb RAM, W7 OS, I use for UFOCapture a dedicated logical hardisk. I tried all suggestions read in this forum but without success.
I tried 3 different frame grabbers and the problem remains Crying or Very sad

Kevin, did you manage to get rid of this serious issue ?

I don't want to be forced to use an old XP laptop to be able to work with UFOCapture.
Any help is definitely appreciated

Have you checked below?
Control Panel > Power Options > Change plan settings > Advanced settings > Hard disk > Turn off hard disk after
The default of W7/8 is 10 or 15minnutes to power off. It should be " Never".

Hello Mr Sonota,

sorry for late answer. Yes indeed, the setting was to "Never".
Consider that the antivirus is disabled (no firewall, no diskscan active), the logical disk devoted to UFO capture is not indexed, having 8GB RAM i don't think it could be a paging issue.
Consider that i can get from 10% to 40% of the total video capture corrupted, i don't really find any regularity that can explain the issue.
What can it be ?
kindest regards

Thank you for clear details.
Well..... it is not easy to imagine Confused , but....

How about physically?
If there are other volumes on the same physical drive, then its head seek time may cause problems.

If you pocessor have enough performance, lossless codec (such as Huffyuf) may solve the problem. It reduces the required HDD speed down to 1/3 or 1/4.
I 'd like to know the detail model number of your laptop, cpu, ahd HDD.
There can be auto spindown HDD or else.

Hello Mr Sonota
I report below all details about the used system:

Laptop Samsung NP-RC730
physical disk Hitachi HTS547575A9E384
CPU Intel i7-2670QM @ 2.20GHz
Windows 7 Service Pack 1
Grabber device: Ion Video2Go

The disk is partitioned in C: and D:, the former about 280Gb is devoted to OS and programs, the latter about 50Gb only for UFOCapture database, not indexed.

About the codec, i'll try, but now my UFOCapture trial period is expired so i'm going to register.
Kindest regards

It seems excellent. There are many UFOCapture users who uses lesser power PCs.
I believe that HDD access to the C: may cause the problem.
But I know that it is not easy to use second physical fast HDD on Laptop PCs.
In this case, not D: but C: may be better because there may be less head seek time.
And using Huffyuv and checking all HDD access by performance monitor and stop stopable task will help to solve the problem.
Cheers.

OK Mr Sonota

I used to capture in C: disk, but the issue was there with same severity.

I installed Huffyuv on the PC and now i'm running a daily UFO capturing session with this coded, if the issue is still there even in this case (night session much worse) few corrupted videos come out.
Just a question, maybe a silly one Confused : coding the AVI in Huffyuv (so, just selecting the coded from the list in UFO) is not preventing me to go ahead in video analysis (UFOAnalyser, UFOOrbit), correct ?

I'll let you know of the outcome.
thanks and regards

Maurizio

It is correct. Huffyuv is lossless and UFOAnalyzer will use its decoder automatically.
The clip requirtes the codec installed for replay or analysis, but there is no other demerits to use it.

Apparently Huffyuv coding doesn't solve the problem (haven't tested on nightsky but on daily capture i got corrupted clips), surely the issue comes from ghost tasks that access the HDD when i'm capturing.
I have to monitor the disk access/performance during a full night capture session, with a timed list of processes that use the Hdd, to be able to relate which process cause that at that particupar time. I don't think i have such an inspection tool directly in W7, anything you can suggest like HD Tune (never used but read of it...) ?
this thing is driving me crazy Crying or Very sad
Cheers
