Software :: Smaller Video File Size With Guvcview?
Feb 27, 2010
I'm looking for some suggestions to create smaller size video files with the following equipment: Logitech Webcam C200 (USB), 640 x 480 resolution, 30 fps, using guvcview software. I'm new to doing video and wish to make short, up to 10 minute, clips. The above configuration puts out only .avi files and those files are huge. One small 30 second clip will cost 30 to 35 MB.
I have a friend using a Flip video camera putting out 30 second clips at 3 or 4 MB tops and the video quality is head over heels better than mine. His Flip system puts out MPEG-4(mp4) files. Other than buying a Flip video cam is there any way I can produce smaller file sizes? Maybe better quality too?
This is on Karmic Koala 9.10. The video displays fine via guvcview using a Logitech webcam. The trouble is the capturing of the video. With .AVI, I've tried different video formats (MPEG-4, flash, etc.) and none of them will play. The generated .avi file seems to grow with data, but the result is just unplayable -- it just hangs, thinking it's playing. Is there a troubleshooting page or something to figure out what the problem I'm having with guvcviewer is?
I feel really stupid posting this, but I can't find what I am looking for. I feel like I have a decent understanding what is going on, but I am missing something very elementary. I have several mpc clientpro machines that are all in one's with 17" monitors built in. I can't get any resolution to fill the screen. I have been playing around with settings in xrandr, to no avail.
In windows xp it is usually ran at 1024x768 resolution which is supported. However there will be about 2 1/2 inches of blank space on the right side of the scree. and then another 2 1/2 inches of blank space on the bottom followed by about 2" of what seems to be a mirror of the top 2". I can change to several different resolutions all taking up different sizes of the screen, but nothing will fill it.
I understand I can't just do anything I like, like it would be unreasonable to expect the card to output 1920x1080. But can't I get it to at least fit the screen? Whether it was 1024x768 or 1152x864 or 800x600.
I have been searching and searching, and I think I am just simply misunderstanding a key term that is not allowing me to find more information on this. Something like panning, overscan, etc.
I have been using Debian on and off since Sarge and it's not as long as most people but since I can remember, the installer has always had some issues and I was wondering if you guys who use Debian religiously could answer these questions for me:
1. Difference between "Netinst" & "Business-card" besides the size being smaller? It seems like the Netinst installs two different kernels. One dated kernel to get the system up and running and then it downloads the latest one where I think the 'Business-card' ISO simply downloads the latest kernel and nothing more which seems preferred. Am I wrong?
2. After I install using "Netinst", why when I immediately perform an 'apt-get dist-upgrade' are there multiple packages to upgrade? I thought the whole point was to install fresh updated packages, no?
3. Why has nobody fixed the installer progress bar from hanging on 33%? As far as I have been using / installing Debian, the installer progress bar is always stuck on 33% & it still installs fine but never shows the user it's exact progress. I would think the developers would have resolved this after 4 years by now...
If I open my 3.3MB .jpg file in Microsoft Paint and re-save it as .jpg it will right away loose it's size and go down to 1.5MB and still keep the good quality.
I have 100s of these picture files, so I can't set down and do it one by one in Paint.
I am wondering if there is any command in Centos 5.4 or tool that I can use to not only make these files size smaller but also to standardize their size to let's say 800 X 600. The latter is not really needed but it will be bonus if someone can guide me.
I am running a php photo gallery script and it takes way to long to load the picture hence the requirement to lower the size for all the files.
I know that there is "mogrify" and "convert" but I think they don't work without GIMP. I don't have GIMP installed and I do install it I think it goes on to install a lot of gnome libraries which I am afraid might break my server or overload it too much. My CentOS doens't have any GUI or gnome package to it and I want to keep it simple.
I am using OS 11.0 Every time I boot my laptop (dell inspiron 9300 - ati video M300). I get the desktop display as 1920 X 1200. This is too large for my default. I use KRandRTray to resize back to 1024 X 768. How can I set 1024 X 768 as the default but still have the option to go to 1920 X 1200?
I want to set my editor's font as Monaco-11, but it has no anti-aliasing effect. And when I set it to Monaco-12, anti-aliasing effect works. How can I make it also work for Monaco-11? I'm using Ubuntu 9.10
Each version of Ubuntu I've used, the size of the text in the virtual consoles (Am I allowed to call it "screen resolution" if it's a CLI?) has varies widely; some versions had the consoles in 80x24 text mode while others used much higher resolutions.this version of Ubuntu seems to use 80x24 characters, which looks really ugly on my 17" screen. Is there any way to make the font size smaller? QBASIC had a WIDTH command to change the number of rows and columns of characters,
I have rendered out less than two minutes of High Definition animation to Avi-Jpeg Format in Blender. Now, I have this 2 GB file. Going at this rate, it's going to take a whole DVD set to play a 15 min movie.
Surely, this file doesn't need 2 GB just for 1:45 min/sec, right? Even at high def? How do I reduce this file size down to like a manageable number, say, 20 miB?
I am using 10.04 LTS Lucid, and I notice the free space of root is getting smaller and smaller.
Five months ago, there was about 3.9GB free space of root, but now it is only 1.6GB. I always run sudo apt-get autoremove and sudo apt-get autoclean every time the update is finished, and also use Bleachbit to clean the system, but both are useless.
I never faced such problem with older versions of Ubuntu, is there any measure to fix it?
I am trying to upload some pics on my Facebook account using Firefox. When I click on Facebook's file upload icon, Firefox bring up a 'File Upload' window. I noticed that smaller image file is previewed on the lower right hand corner, while bigger image file is not. Is there anyway I can change this behavior or maybe change what Firefox is using to browse my files?

I never faced such problem with older versions of Ubuntu, is there any measure to fix it? 1. There is not any .deb in the /var/cache/apt/archives. 2. The total content of /var/log is only 167.6 MB, that won't be a problem.
I have a single VRO file from my camcorder, it is made up of about 100 different clips, they show up as individual clips on my camcorder, but only as a single file when I take it off the camera. Is there any program that can extract or split this file back up into the different clips? It's a pain trying to edit this when I may only need one clip out of it (total number of frames is over 132,000!
I would like to know how to make the file browser column width smaller than I can normally adjust with the mouse. I have minimized with the mouse, it is still too wide. Is there a minimum column width setting I am supposed to specify somewhere?
I have a 500MB video that is 720x400. I want to half the size of the video while retaining the same relative quality.My main goal is to half the filesize of the video, but to do that and keep the same relative quality I will have to also make the resolution smaller.I can't seem to find a way to do this.I would preferer to use ffmpeg, but any solution would be good at this point. I would really like to be able to do this from the command line, but if there is a gui program that will also give me the command line it uses, that's great too.Does any one know of a way to half the file size of a video while maintaining the same relative quality?
