FAT32 vs NTFS for Video Capture Hard Disk

[jfebus]

HI All,
I have two 40GB IBM HDs and they are formated using NTFS. I have several frames dropped every time I capture. If I convert the HD to FAT32, will I get a perfect capture?

Are they 7200RPM drives?... Defragmented?... What are you trying to capture with... (format i mean)?

Id recommend staying with NTFS though.

Try the things ive said above (defrag) and then try capturing with the Huffuv (i think i spelt that wrong) codec. (check the how-tos on this site for further reference)

enjoy

HI,
Thanks for the advice. I did ran defrag and then I even format it.
I try to captured to my C: with out any frame been dropped.

How many frame drops are you getting? It's quite common for a few frames to be dropped during longer captures. Because most sound cards are slightly inaccurate, some frames are dropped to keep the audio in synch. As long as the frame drops aren't numerous and don't occur in bunches, you shouldn't have to worry about them. (Use VirtualDub's Edit -> Move to next dropped frame to find the location of dropped frames in your video.)

You may want to check if your hard drive is set to an Ultra DMA setting that it inappropriate for your motherboard and cable. You'll need to get the utility from the drive manufacturer. Very common overlooked mistake. Normally would result in other hard drive type problems besides capture

I have the same problem on my PIII 500 with W2K, using Vdub.
When i use avi_io, the framedrop is minimal.
Caputured an Star Trek episode with Avi_io in 352x288, 244 in sound, I lost 6 frams in 45 min., under W2K.

jfebus,

I notice in one of your notes that you said you were trying to capture to drive C without any dropped frames, if I understood you correctly. If the C-drive is the one your system is installed on and contains your swap file, you may want to consider capturing to another drive since Windows accessing the swap file will cause problems in a high bandwidth situation like capturing 640x480.

I still can't tell what happened on mine, but here;s my two cents (maybe someone else can explain if I've on track)

I run dual-boot Win XP RC1 / Windows 2000, on C: and D: respectively. C: is a 12 Gig drive, D: is 40 Gig.

I use Windows 2000 to do all my video encoding, captures (fairly obvious there). I all of the sudden had dropping frames, of the fatal variety (where I could not get video to synch with audio, because video frames didn't keep proper timescale at all, and there were several second gaps)!

This was on my D: drive which I used to capture on, by habit. I tried defrag, didn't work. Could it have been because of the Windows swap file? Probably...

I did another capture last weekend, of over an hour MPEG-2. This time to the C: drive, which said it didn't need defrag. Sure enough, not ONE dropped frame!

So, it pays to:

Defrag

AND/OR

Use DMA mode

AND/OR

Use a drive your OS isn't on!

...at least I'm pretty sure
