Ubuntu Multimedia :: Converting Multiple BMPs To An AVI Without Compression?
Aug 1, 2011
I am trying to convert hundreds of BMPs into a single AVI file, without compression. Since every pixel matters in my case, I don't want any kind of compression. It's fine if the output file is extremely large.
I'd like to know if it's possible to achieve this with packages coming with Ubuntu 11.04. I have tried ffmpeg/mencoder, but they either compressed the output file, or the output file is not playable in totem. I am a new user for both tools. there is actually a way to get uncompressed avi from these tools.
"BMP to AVI Sequencer" [URL] does the job perfectly. I successfully converted 180 1080P BMPs into a 1G avi, running at 30 fps. Unfortunately I need a command line tool this time.

I use mplayer to play my media files. Occasionally I want to take screenshots of media I am playing. I use the -vf screenshot option to take screenshots which generates shotxxxx.png. The issue is that all those png are not compressed and usually large. When dealing with Hi-Def media they are extremely large, each is 4-5 MB in size at the least. Is there a way I can set the option for compression of png images. If I use imagemagick the same files get compressed to like 1.5MB of png file.

some reason it seems like the lowest it goes is ~64kbps (~ implying variable bitrate).So yeah, any thing that'll let me do the compression limbo better? (How low can you go? ) A different program? Unlock bonus stage? What

I want to rip all my CDs to flac at the lowest compression (space is not an issue) via Banshee. I have tried a few tracks but the seem to be ripped at a higher compression to the ones I have done via sound juicer (set at compression 0)
How do I adjust the flac settings in Banshee to do this? The option to edit the settings is not available for flac? I guess there is a config file somewhere?

I finally got K9copy to work and I'm using it to extract DVDs to my hard drive. I extract a dual layer DVDs it becomes a 5GB DVD. In the settings, I have DVD size as 9GB because I assumed this would not cause any compression. When I use k9copy assistant to change the shrink factor before ripping, I can only change the shrink factor of some titles to 1.67 from 2.50. I want the shrink factor to be 1 since this seems to ensure that the output of the file is the same size as the title on the dvd. I want the copied DVD to be the same size as the original. I have no problem with hard drive space since I have 6 terrabytes of free space.

I'm head engineer for a community radio station. One of our compressors has recently died and I want to replace it with software compression on our streaming machine. I've been looking at VST/LADSPA/JOST etc and I've got nothing but confused. Hence I'm coming here looking for help.
My spec is this. We need a system to run a compressor and EQ, probably a graphic and a parametric. The compressor needs to be multiband and have proper control of the compression curve. A way of configuring it without too much command line work would be an advantage. All needs to run on an Ubuntu server with not massive overhead as it's not exactly the latest hardware. I suspect it would be possible to run WINE for windows requiring VSTs if needed.
I was hoping some of you good people might be able to point me in the direction of a suitable host and plugins to achieve the effect described.

I have spend the entire weekend trying to convert a mkv file with a DTS audio track to an AC3 audio track. I wrote a small article on it on my website with plenty of links and suggestions. I used applications like TVersity, PS3 Media Server, mkvdts2ac3 script, and avidemux. I just hope i can save someone's weekend with this. Anyway here is the link:

i am converting my DVDs into a media library. The ripping itself is no problem. (using Xilisoft dvd-rip under wine; works flawless).
when i convert to a mp4 file, with good quality, the output is always around 1.2 -1.8 gb. depending on the movie file. i tried Xvid and the size is pretty much the same. only by reduucing the pixel size etc... i get like a 600-800 mb file.
when i see other ripped movies, with about the same movie length, they getting 800mb mp4, in perfect quality, no smaller screen, pixels are great etc... is there any kind of advanced setting to it? bitrate, audio? to get down to this file size..?

I have mediatomb (0.12.0~svn2018-6ubuntu2) installed on Ubuntu Server 10.04.2 LTS which I use to serve video to my PS3 (slim version). MOst videos work fine but I have some mkv's giving me trouble.I'm trying to use mencoder to re-code the video to one that the PS3 can play. mkvinfo says the video track is Codec ID: V_MPEG4/ISO/AVC and the audio track is Codec ID: A_AC3.I used this command to convert to avi (found it in a thread on this forum):
mencoder -oac mp3lame -lameopts cbr=128 -ovc xvid -xvidencopts bitrate=1200 video.mkv -o video.avi
but the PS3 says the avi is an unsupported format.

I am in Toronto Canada and we have NTSC television. I am going to England where they use PAL. My mom's DVD player cannot read NTSC.
I have a TV show on my PVR that I want to burn to a DVD so that she can see.
I have to output the program from the PVR to my DVD recorder; I do not have the hardware to send directly to my computer.
So I believe I must follow these steps:
Rip DVD to computer
Convert to PAL format
Burn to DVD

Trying to burn with CD/DVD Creator. I can't find anything in the program (settings wise) that will automatically convert mp3 files to wav files. I used to use k3b, and it used to do that. I did try installing k3b, however I am getting glitches in the program. I don't want to covert mp3 files over to wav every time I want to burn a new cd. Does anyone have a suggestion as to another program or place to find the burn setting for encoding?

To Ubuntu after switching from Windows Vista. So far I really like it. I am trying to convert music in wma format that I purchased on Zune to mp3 format so that I can play it in Rhythm Box and use it on a SanDisk Fuze that I recently purchased. I installed Sound Convert. Sound Convert works fine when converting wma files that were created from ripping CD's. However, it freezes when trying to convert wma files that were purchased from Zune. Also if I try to double click on one of the wma files to play it with movie player, I get an error message saying that the file is encrypted and decryption is not supported.
I did find a converter on Windows that works. However, it was a trial version that only converts 90 secs. The full version costs $25. I do not feel that I should have to pay for music that I have already paid for. The music was purchased a la carte from Zune (not with the monthly pass). Does anyone know of a workaround to free my Zune music so I can access it on Ubuntu?

The problem is the only video codec that iPod touches can playback is MP4. My Psych episodes are AVIs. I've heard of and used mencoder to change video codecs before, but I'd have no idea how to write my own script for it. What I was thinking of doing is using Avidemux to convert it? Open the AVI in adivemux Switch the video to MP4 Mpeg-4 switch the audio to MP3 lame
Honestly i'm not too firmiliar with codecs and containers but its telling me that rather than Xvid(which i think it was previously) the video codec is MP4 and the audio is MP3, and the container is AVI. First of all is this correct? Did i get the codec/container right?
Secondly will this work on my iTouch? I guess dealing with AVIs as a container is ok as long as the video codec is MP4? rather than like OGG or something? Ugh i'm so confused, i've just been rambling..
Ok. First of all do i have codecs/containers down? Am i correct with my assumptions? Second, I am correct that the CODEC is the problem, it must be MP4 to play back on the iPod? the container being AVI has nothing to do with it? (i'm basing this off of the fact that i know the only "codec" iPods can playback is MP4)
Edit: are there any other possible ways to convert an AVI to an MP4?

I copied some songs off a CD and wanted to convert them to mp3. Is there a program that I should have used to rip them that would have done that or is there a program that will convert them for me?

I need something that will convert and then burn a DVD. I have tried almost all of the options on Ubuntu including Devede, K3B, Avidemux, Qauthor, Tovid, Transmageddon, DVDstyler and probably more. None will convert to a NTSC format without trying to create a DVD menu which seems to be the problem involved in playback except for Transmageddon, but it fails to provide the bup and ifo files to go with the video files to get K3B to burn it. I'm able to make DVD's that work on computers, but I want DVD's that will play in my DVD player. Any programs other than the ones I named that can do the conversion without creating a DVD menu and create all the files needed to get K3B to burn it? If needed, I'm converting from AVI. Also,

Is there a way (strictly in Ubuntu -- well I am viewing the noteworthy files under wine) to convert these files to lilypond format? I have tried the nwc2ly converter, but so far without any success. Any thoughts, or suggestions? You see I have a friend that has done a lot of Orthodox Music in NWC, but I want to get it into Lilypond as it will look better, and then I can easily convert to pdf, and easily change things if needed, etc. But I would rather not have to print and retype it all.

I just purchased a new digital camcorder and after recording I realized that it records that the files were not in a format that I am use to. I need a program or code that I can use to convert these files into a format that I can watch and that I can manipulate to make a longer movie.

I have just captured some screen-shots with GTK-RecordMyDesktop, but now I can't use them. The videos plays right in vlc and totem, but crashs Pitivi and turn into pink splotches in kdenlive. When I convert them using ffmpeg, the video turns into blue and pink splotches. Here is how I'm converting it:Code:ffmpeg -i out.ogv out2.mpgConverting it with vlc crashes the program.I never had problems like this before. I have used recordmydesktop and ffmpeg many times, but on a 32bit computer. I have a 64 pc now, running ubuntu 10.04 x64.

I converted using a simple app called sound converter to convert my mp4 vids to flac (because they were music i didn't need the picture.)
Which is bad because one of the main reasons I wanted to convert is because i thought removing video reduced the file size.
For example one file went from 6.4mb mp4 to a 19.7mb flac.

We are working on a project to create a display wall of 8 monitors arranged as 2 high by 4 wide. Each monitor is connected to a single machine and all machines are networked with a master machine with its own, seperate monitor.
Our goal is to get the 8 machines to share a single desktop, with the master machine acting as the server. We have looked at using Xinerama or NMM, but we are unsure about how to get started configuring the multi-machine, multi-head display.

I tried converting wma to mp3 with vlc, but an error comes up this is what it says.
p, li { white-space: pre-wrap; }
Streaming / Transcoding failed:
It seems your FFMPEG (libavcodec) installation lacks the following encoder:
MPEG Audio layer 1/2/3.
Either how can I get that encoder for vlc or what else can I use to convert wma to mp3?

I've seen posts with similar titles on these forums, but I know nothing about the plethora of codes out there and all those thread seem to be way over my head. I've installed ffmpeg (an unrestricted version) but I can't convert m4a audio files to mp3 audio files. I installed a package called 'libavcodec52' from synaptic because it came up in the search results for 'm4a' and its description said something about m4a and ffmpeg but still no luck..
