Fraps recording 3 minute, 5 GB movies? Why?

Just bought the full version of fraps and tried out the video capture. After an hour recording I find all the movies have been split into 3 minute videos, each one is 4.9GB in size. I tried running VirtualDub (compressing) but afterwards that 3 minute movie became 16 GB!! Somehow...
What on earth?

Check your quality settings. They're probably up way too high.

Fraps files are always going to be ginormous. I don't recall it being that bad, but they will always be big

They're not the proper file format. You can convert them after you're done with the raw footage.

Use Windows Movie Maker or Sony Vegas and edit them, depending on the format of the rendering you will have a smaller file. Like 10Mb.

Because it has to record in real-time while your computer does other stuff, Fraps dumps raw video data into the file. It's incredibly space-innefficient, but it's high-quality and you're expected to compress before using.

Because raw video is fucking huge. Change the file format after recording.

I tried compressing using VirtualDub, but that didn't help. At all.
Perhaps I'll get Moviemaker and use that instead.

You were recording at 1080x1920, weren't you? And with sound turned on too, probably.

All the movies are meant to be that big from fraps, as they are uncompressed, this lets you have better frame rates when recording.

1) Open virtual dub
2) Open movie (first part)
3) Append avi segment for each part afterwards (in order)
4) Go to compression and use the following:

Codec: FFDshow if you do not have it, download and install this: http://www.cccp-project.net/
Presss configure
Encoder: MJPEG
Bitrate: Set to max then mess around with settings to suit your fancy

5) File > Save as avi..
6) Save and watch

No problem ;P , quote or PM for any further help.

1080x1920? Surely you mean 1920x1080 :P

Because it records in real time, it hasn't got the time it encode it and compress it, and even if it could, that would be a ginormous amount of computing power. So it dumps it in without encoding and compression to keep system speeds up, and it limits it to 5gb so when you do go to compress, it won't take an age to load up a 80gb file.

And what about the length? Are they always 3 minutes, or is that just due to file size?

The file size limit is usually 3.9GB or 4.9GB and it will cut it off then.

Because 3min is equal to about 5gb in your rendering rate, I would guess.

What most people said in this thread is completely right.

VirtualDub is a great free tool to compress video, you need to select the appropriate codec first, FFDShow based codecs are great, too. :)

I downloaded CCCP but my options under 'compression' don't change. Any reason this might be?

This is entirely correct. Uncompressed video means each frame is entirely new data from the previous (the most basic and often used compression only updates pixels that change from frame to frame rather than having lots of extra information) and this can be enormous (for 1920x1080 at 32 bit color depth, this equates to about 64 megabytes per frame, 3 minutes is 4500 frames at 25 FPS). The actual process of compression is computationally expensive as, in the most naive interpretation the algorithm must check each pixel in one frame against the same pixel in the next frame. This equates to roughly 2 million individual checks per frame. The end result is simply that few computers would be capable of doing this in real time (in a single second it would be required to perform 50 million checks with the actual number of operations being several times as large. Given that any given step, even the most trivial computation in the process, requires several clock cycles to complete (several dozen cycles just to grab the data of a single pixel from memory followed by many more clock cycles to compare the two), you quickly find that, even at the very high frequency of clock cycles on modern computers, you simply cannot do the job quick enough. As a result, the program has no choice but to simply write the raw data to disk so that it can be compressed later.

I usually go for the K-Lite complete codec pack. I'm not sure if CCCP comes with the proper codecs to actually compress files, if only to read them.

Also make sure you use VirtualDUB x86. 64 bit based codecs are actually rare. Basically the 32 bit version of VDub can only read 32 bit codecs, and the 64 bit can only read 64 bit codecs.

Well I'm using the 64 bit version of VDub but I have no idea what the codecs are :/ Just downloaded the CCCP pack recommended but it hasn't changed anything.

Use the 32bit version. The 64 bit version doesn't have enough codec support.

You're telling me, I just downloaded the K-Lite pack as well and still nothing.
I'll try 32 but if that doesn't work I might just drop the whole thing and stick to Movie Maker.

Right, just tried the 32x version and no difference. No compression options showing no matter what codecs I have installed- I hereby declare this a waste of time.
Plus its 3 am and I'm tired. Uninstalled everything and decided to just use Moviemaker from now on (still 500MB per video but oh well).

This used to be a quirk of non-NTFS file systems, but now it's a universal 64-Bit problem. Normally, you can stitch them together in VirtualDub.

Yep. That's about right.

FRAPS doesn't compress the videos while recording, which means higher quality videos for you (a good thing). The video and sound alone for that three-minute bit was a total of 16 GB uncompressed. This is why high amounts of RAM are recommended nowadays.

You have to compress them manually using VirtualDub or another compressor. VirtualDub is handy, if you have a compatible video codec.

Which I don't.

And they're ridiculously hard to find.

If you find a goo one, could you please tell me about it?

(Fun story: Due to a glitch in VD, my seven minute video ended up taking up about 212 gigabytes of space. I couldn't even drop it in the recycling bin, it was so massive.)

Easiest thing to do is open up Windows Movie Maker. Import every file and add them all in order to the timeline, then publish it as an MPEG. Depending on the settings you choose, that should effectively compress the entire thing to a mere few MB with barely any loss in quality. Then you can delete all the raw footage and use the new file as your new 'raw footage' to do whatever you want with.

Seriously, that does work. I had half an hour of footage a few days ago to turn into a 45 second trailer as part of a commissioned job, and it was around 8GB originally. After I did this I had the same file, barely any drop in quality, taking up only 481MB, much more suitable for my crappy laptop to handle.

And this is exactly what I'm now doing. a 20GB+ 11 minute video down to 400MB. Still too big for my taste but at least it isn't eating my harddrive.

1080x1920? Surely you mean 1920x1080 :P

What's wrong with portrait mode?

FRAPS files for me are always huge.

I don't quite remember the program I use to convert them, but it's really good and 3 minute files normally come out < 50MB, still HD.

I suppose it's just the lack of compression in FRAPS.
