Min CPU speed for capturing

[compaq76]

Hi,
What is the min speed of CPU required to do an acceptable video capturing and convert to VCD?
Does HDD speed and FSB speed plays an important role?

I've tried to capture from video-in to AVI file, when playback the AVI file, the movie very jerky. I'm using an AMD 350 processor.

BTW, what is the min HDD require to capture a 70min movie from video source to AVI file?


Thanks for help

Well I am on a Pentium 3 - 450, and have 256mb SDRAM, and this is probably the bare minmums for capturing.

For 70mins of video in an AVI File it depends on how you capture and what with, I have found most success using Huffuyv, and 70mins would be about 11.2 gig... so pretty big hehe.

I thinks your best bet will be to upgrade. Otherwise you will get way to many dropped frames and audio/video wont be synced.

cybermage26, i would like to know how you can get 11.2 gig for 70 min worth of video with Huffyuv.i use up about 12 gigs for 36 min. what are your methods of captureing????

Ok,

The answer to this question depends on what you want to capture with.

Hardware card:
Your pc is not that important, as the hardware capture card does the work, and the data going to the disk is not as much.
Software card: you need some decent cpu.
Non compressed software card (avi): you need a decent cpu, and some fast disk.

I would go with a hardware solution (pv256, DVCii, ADS etc.)
UNLESS you need to upgrate your computer in general.

My cpu is plenty for 90% of what I do EXCEPT video....I am getting an ads.

Thanks for all reply.

What is the min speed do I need that can be consider as a "decent cpu"?

I capture at 352x288, maybe you use a higher setting..?
But anyway, I just made a very uneducated guess on the 70min thingy anyway, I recorded 1minute of video which came out to be like 160mb, and times that by 70, thats how I got my answer of 11.2 gig ..

Here's my personal experience, Compaq76:
You absolutely need a 7200 rpm HD. Don't forget to install the UDMA driver. Space required for capturing:
1) If I use a DV500, I'll need about 12-13 gig/hour.
With a DVCII, it all depends on your capture settings. They have three settings: 7.5, 22, and 30 MBytes/minute. So to obtain the HD space needed, just multiple the above settings by 60. Ex.: At 22 MB/mn, you'll need 1320 MB/hour.
2) Use the fastest CPU your budget allows. The difference in price is very small between 1.2 and 1.4 GHz, and they don't sell 800 MHz CPUs for a long time now. But it will save you a tremendous amount of time in case you use TMPeg. With an 800 MHz CPU, it took me 3 hours to encode a 25 minute AVI; when I upgrade to a new 1.33 GHz, the time needed dropped to 2 hours, so that's significant.
3) By the same token, buy the fastest bus speed you can find: 266 MHz, and a minimum of 256 MB of DDR RAM.
4) If you plan to buy a Dazzle DVCII, avoid the VIA KT133 chipset. Look for the KT133A (read the manual for the motherboard to find out). I had a lot of problems with it, but now I learned to make it run most of the time.
Hope that helps.

Hey networkswiz

thanks for the great explanation.

I can do you one less, slightly.

I use a dated Celly box that I have lying around for my AVI caps.

Celeron @ 400mhz only
96mb RAM
Pinnacle Studio PCTV Pro card
cheap Maxtor 60gig 7200rpm as the [slave not master]
NO lossless codec captures like Huffyuv or MJPEG
only full 24bit UNCOMPRESSED RGB

only 2 fans, the cpu and power supply fan

this thing NEVER heats up, only on hot summer days
used to have a water based HDD cooler that fit right between to 3.25in bays, but after I removed it found there was no difference with the cooler installed [but who's inside on hot summer days when you can be at the beach peeping the dips]
