Yesterday I filmed a tom turkey showing off in front of three hens. I filmed five and half minutes or so of this and the footage is taking up 1.14 GB. I was looking at some deer I shot last year with the same camcorder and a ten minute and twenty second long clip only took up 622 MB. I also shot about 12 or 13 minutes of deer over the weekend and the clip took over 2GB. Why are my clips taking up so much more space now and how do I fix this?

Sounds like a setting on the camcorder has been changed, whether you meant to or not.

^ Exactly correct.
Rather than trying to make smaller files, you will someday hate yourself for choosing lower resolution (which gives you smaller files) over good video quality.
Things that matter to you, that you're filming for yourself, deserve a setting that equals "SP" (or better if you have the equipment that is capable of benefitting from the "HD-level" files when you view them).
Remember, you can always burn up to 4.35 GB (4459 MB) of files to a .25-cent DVD if you need to conserve hard-drive space :)

It's not the hard drive space that is the concern it that I can not upload anything with more than 1 GB to YouTube. I'll double check all the settings on my camcorder, to the best of my knowledge I have not changed anything.

Just checked all my settings. Nothing has been changed. Even a month ago I was uploading nine and a half minute long footage to YouTube with no problems. Now a five and a half minute clip is taking too much file space.

Perhaps there is a setting on YouTube that has changed?
Do they allow you to choose what resolution you are uploading (up to the 1 GB limit)?

Are you using some sort of editing program to capture the video to the computer? If you are, you need to check the settings on the program to see if it's capturing the video and audio at a higher quality than your previously captured footage.

Roughly speaking SD video captured in AVI format is 1.9GB per about 9min and 36sec of footage captured uncompressed. BigBob is right...always capture in max resolution for later use. You can use a program like Sorenson Squeeze or Cleaner XL (there are dozens of other) to compress the full res clip to an optimized youtube format like h.264 which will give it the option to be viewed in high quality. If you're editing it. Still render it out in full res uncompressed or with a good DV AVI Codec and then use either one of the programs I mentioned or the editing program itself to render out a smaller sized version for upload to youtube. Hope that helps.

Another option would be Nero (many people already have Nero).
You can open a non-copyright protected movie (such as your original home videos) using Nero Recode (part of the Suite). Then, you can edit your movie (selecting the start and stop points) and burn it again at any quality level (in 1% increments) you choose to, to get it under 1 GB.
If you really want to get into creating a movie out of many pieces (resulting in a single contiguous movie), you can do that with NeroVision Express. You can then choose to save it at multiple resolutions (equating with EP, LP, SP and HD as found in hardware recorders) in order to get it under 1 GB.
Typically, a DVD recorder can record two hours of "SP" level video onto a DVD (which will use about 4.3 GB of space). That's .0358 GB/per minute.
So, this means you should be able to have about 27-28 minutes of "SP" quality video and keep it under 1 GB.
You must be recording at "HD" quality, and/or having it being expanded to HD during the upload process, to be having a problem keeping it under 1 GB (which is really huge for an Internet video file).

What I'd like to know is, is there a program that will easily (and quickly) compress full resolution AVI videos into something of comparable quality but much smaller size? Every time I've tried to compress an AVI file from my camera, the program was either way out of my range of skill or the video came out looking like total shit. These videos (From an early Sony Digital8) look great at full quality. I don't want to trust burned DVDs with this content but I don't have nearly enough hard disk space to just store them all on a drive at full quality.

Do you want quick or do you want quality? I don't think you can have both, though fast processors can help. At ay rate, try AutoGordianKnot. It's free, so you aren't out any money if it doesn't suit.

Ideally, I'd just like good quality compression that doesn't take a month for each video. I've never really had a serious problem with waiting reasonable lengths of time if I know the quality is going to be worth it. It just seems like any significant compression simply kills the quality. I get stuck on those kinds of compromises. On the other hand, sometimes even if I know it's worth the wait, the processing power it takes to do it brings my PC to it's knees if I want to run Foobar or something while it's running.

My limited understanding is that good compression is not a simple, one-step process. Ergo, getting a decent quality image is going to take some time, and you can't expect to have much processor power left over to do other stuff on your computer.

@RP: I assume your AVI files are using the raw DV codec, straight from the camera. If not, what codec are they using?
If so, I'll further presume that your camera is 4x3, and the files are huge, like 1 GB for 4.5 to 5 minutes of video.
I personally hate throwing away originals, but if you can live with it, you might try compressing them with XVid for the video and MP3 for the audio. This guide has *most* of the details, including downloading three or four packages that you'll need to get the job done:
http://forum.videohelp.com/topic244151.html
I think you can skip the first step, as you already have the DV files on your system. I'd try bitrates between 1000 kbps and 2000 kbps for the video and see if you can see any differences between them and the originals. I'd encode like 20 to 60 seconds of video at a time as a test bed, evaluate, adjust, and repeat until I found the right rate. Once you find the right rate, you can save the files as XVid/MP3 AVIs.
However, note that VirtualDub has an "add to queue" setting. This queues the job up for later processing. Once you're *sure* about all the videos you want to convert, you can load them up one by one, add them to the queue and move on to the next. Once you've got 5 or 10 or 20, or whatever number of videos queued up, go to job control, and you can start the queue running. They'll crunch away for however long it takes, video by video, until they are done.
You may feel some impact as it encodes them. I don't usually see much difference but YMMV. You can always stop (and later restart) the queue if it's impacting the PC. You can even run the whole batch overnight while you're asleep. Hope this helps.

Thanks for the effort DrP but I've tried Xvid/Divx, etc. Basically, I wasn't able to get a level of significant space savings that didn't make a noticeable difference in the quality.

That's extremely surprising, as DV isn't a very good codec. XVID should give you significantly better compression, even at a high bitrate like 2000 or 2500 kbps. Oh well, I tried...

To address your space problem, you should purchase an external hard drive, preferably one that is at least 1TB and store your full quality content there. When using any conversion program, have any temp files and finished product sent to the external hard drive. The more free space there is on your hard drives, the better the computer will run. NEVER LET ANY HARD DRIVE GET DOWN TO 15% (PARTICULARLY THE C DRIVE/OR OTHER LETTERED COMPUTER MAIN DRIVE) OR ELSE THE COMPUTER WILL JUST ABOUT COME TO A HALT.
Now to address your processing concerns. I don't think there is a program out there that won't use a good deal of CPU power to run it unless someone is using a quad core computer meant for professional editing or something.
I've mentioned this somewhere in another thread. The technique I use is to restart or turn on the computer, right-click on any programs that aren't needed on the System Tray and shut them down. Especially anti-malware programs as they tend to be the largest resource hog on the System Tray.
Once everything is shut down, don't click on anything but what is needed to run the conversion program. I shut down my Internet connection also so I won't get any updates from my anti-mallware program or any other possibility of intrusion.
At least on my computer, the reason I do this is because once I open almost anything, even if I completely close out of them afterward, the CPU and PF usage is higher. I try to get these values down as low as possible before starting the editing process. Obviously this is because simply clicking on certain things causes something to run in the background that can't be shutdown in the System Tray.
I use the Performance tab in the Task Manager to track all of this. In closing, to my knowledge, you are never supposed to use the computer while doing any editing. If you're only converting a small file, I guess it's okay. Just try to do any major editing or conversion when you don't need to use the computer.
