FRAPs doesn't compress its videos when you record, so the files are enormous. I recorded about 600 gb in one go.
Obviously, usually you would need to convert/compress them. What affects the speed of this? I don't think the RAM does, as when I converted the 600 gb my RAM usage didn't go up, but the processor was at 100%. Would clock speed or cores help the most?
Also, how much would the actual program you used affect is - if you had a stereotypical Microsoft program, is that likely to lower the speed significantly? |

| If your program knows how to parallelize, then cores would be significant. Also, RAM speed is probably the greatest bottleneck here. |

| When I record like 1 minute in FRAPS it's only like 500MB for me. 600GB in one go?? What's your highest recording time with FRAPS? |

| And when I do a 4 minute video and compress it in Camtasia Studio to HD it goes down to 123MB!! |

| Exactly, my compressed 600 gb is not about 100 gb. |

| @myrkos - are you certain about RAM? I have 12 gig and only 6 gig was used, whereas my processor (3.46 ghz with 6 cores/12 threads) was at 100% for 5 hours, and the only time it has ever gone to 100% before is through benchmarking. |

| Speed, not size. The greatest bottleneck on the CPU for this kind of stuff is waiting for the RAM to respond to its requests. |

| or you could just stop using CRAPS to record videos. |

@trapping
recommend better one
@Myrkos Presumably then it wouldn't use the RAM, it would just use the cache? After I looked in some other forum I found that it is mainly processor, and the converter used all the cores, so the 6 cores probably helped.
It took nearly 6 hours overall, I'm wondering what it would be like with less RAM speed and how that would compare with less CPU speed.

| I doubt it can convert multi-GB videos without accessing the RAM... the cache isn't THAT big. |

camstudio (With lossless codec otherwise that's even crapper) Camtasia (Need to cough***legitimately***cough obtain it though) xsplit
anything is better than craps |

| CPU cache is most likely just 16 or 32MB. |

| Surely it wouldn't need to store everything at once, but just tiny parts at a time? |

@trapping
camstudio - terrible camtasia - expensive and not as good as fraps for games, I've tried xsplit - have to pay to make it good for games |

And every time it switches between those tiny parts (quite often) it has to get them from the RAM. |

camstudio - terrible - Obviously hasn't used lossless codec. Since you don't seem to realise what difference a codec can do I conclude you're not as smart as I thought camtasia - expensive and not as good as fraps for games, I've tried - But doesn't result in your hard drive killing itself years before it should. Burning GBs a second CANNOT be good for it. xsplit - have to pay to make it good for games - Umm.. No.... It's free.... (For now), and when it's not, it's very cheap anyway |

Use hypercam3 with a good video compressor. I've been using "Xfire video codec" which a 1 hour and 30min video is about 43GB without touching it with any other program and the quality is pretty good.

No idea what a codec is, so that's probably why.
xsplit is worse than fraps for recording games unless you pay for the special games thing: I know, I've used it.
@Myrkos - yes, but the section swap does not cause significant slowdown compared to the speed of the processing of the parts. There is a bottleneck with the RAM speed, but not as big as the cache size and processor cores (that's what it looks like). I don't know how much the clock speed affects it.

"No idea what a codec is, so that's probably why. "
oh god and you think you can insult a recorder without even tryin--
no.
with the lossless codec you can get __1080p__ *WITHOUT* lag, at FLAWLESS 30 FPS on a _REGULAR HOME SYSTEM_. And since yours has crap-loads of everything, you could probably record at twice that resolution.
Just try it, but make sure you install the codec right. Camstudio on it's own is complete crap, with the proper codec it's proper good inni
Trust me, I've got practically every recording device going, or have had, on this system, all legitimately obtained, (cough cough) and none of them can match it. Xsplit's pretty good though. |

Trapping, in my experience I have felt that Fraps is better than the other ones. Maybe they have improved now. Also, the biggest bottleneck is RAM and your HardDrive write speeds. CPU is almost never the bottleneck.
There is a reason video editing machines have 24-32 GB of Ram. But of course, once that is saturated it starts paging, and that's when writing to your HDD makes a significant impact. Hence, video editing machines come with Solid State Drives. Also 600 GB of video in a single go? Sounds wrong. A minute of footage is 1.5 GB approx. You took 400 minutes of footage in a single go? Why?
