You can encode to Theora video and Vorbis audio with ffmpeg if it has been compiled with --enable-libtheora and --enable-libvorbis. Depending on your ffmpeg version the default settings may not provide good enough quality. Therefore you must add some additional parameters to enable a constant quality type of mode for the video. Theora video Adjust video ...

What you are talking about is upscaling and any current HDTV will do upscaling automatically. Upscaling doesn't work miracles though, it will only make it so that the lower quality signal can be watched on a higher quality display. It just multiplies the pixels so that a 720 by 480 (.9 pixel compressed) signal for example doesn't end up only taking up 1/4 ...

ffmpeg has removed their x264 presets so the -vpre setting doesn't work any more. Now, I have a script for converting video files to a format my Cellphone can handle. ffmpeg -i input.avi -sws_flags lanczos+accurate_rnd -vf "scale=320:240" -c:v libx264 -crf 20 -preset veryslow -profile:v main -tune fastdecode -c:a copy output.mkv I'll explain each option ...

Thanks to Brads recommendation, I used ffmpeg for the job. Here is a small bash script that converts all the mp3 files to mpeg4 avi files (a jpg image must be included in the folder): #!/bin/bash # Requires: ffmpeg # Usage: ./convert.sh for file in *.mp3; do ffmpeg -i *.jpg -i "${file}" "${file%.*}.avi" done Some more info here and here, but that ...

You can use wonderful ffmpeg for your desired workflow. There is a guide here on this page but once you have the ffmpeg installed, you can simply cd into your folder with sequence, and type in your terminal: ffmpeg -f image2 -pattern_type glob -i '*.png' -vcodec qtrle -r 25 -s 1920x1080 test.mov To understand the options, you can check the documentation ...

The cabling is likely your problem. The composite cables you're using (red, yellow, white) will only move analog signal from the set top box to the TV. Likewise with RG59 or RG6 (coaxial). While both varieties of cables there are technically capable of passing digital signals (they don't care... they're just dumb cables), set top boxes typically only ...

Wonderful ffmpeg command line utility is the solution. Just check their documentation, but something like the following will probably work for your case: ffmpeg -i video.mts video%05d.png This will take your video, and create video00001.png, video00002.png... files in the same folder. You can find a lot of guides for ffmpeg, or ask here for a specific ...

I'm trying to help. First, I don't understand why you're saying FFMPEG H.264 is not the input format? I don't know the FFMPEG command line well enough (is there anyone who does? ;) ). There's got to be a switch for multipass encoding. I know there are some built-in presets you could probably use and do almost certainly what you're aiming for. These are ...

Devices are often picky, and specifications are usually too uninformative so it's always trial and error. For example, your link indicates that the phone supports MP4 playback, but that is simply a container than can utilize several video and audio formats. MPEG-4 part 2 video and AAC-LC audio (partially based on the working video details you provided) ...

If you had just 4:3 and 16:9 videos, I would suggest: ffmpeg -i input.mov -filter:v 'scale=-1:768;crop=1024:ih' \ -c:v libx264 -crf 23 -preset veryfast output.mp4 That would scale a video to a height of 768, scaling the width to keep the aspect ratio; and then it crops the width to 1024, keeping the height at 768. However, the fact that you are using 1:1 ...

For a server, you definitely want ffmpeg. I would also strongly recommend compiling it yourself (those are Ubuntu instructions, but should work for Debian as well AFAIK) - the best AAC encoder available for ffmpeg (libfdk_aac) cannot be redistributed alongside x264 (because of the GPL), and the version of ffmpeg in the repositories is probably too old for ...

Many different factors can contribute to stutter in video playback. It could be a CPU issue (check your CPU when playing the video) in which case, a simpler codec or a player that can leverage the graphics card for decoding would help. It could also be data rate related though. In this case, using a simpler format would actually compound the problem as ...

How old of a Mac? MPEG Streamclip is a great option. This free software requires at least Mac OS X 10.2 (Jaguar) and QuickTime 6. It is also compatible with Mac OS X 10.3.x (Panther), Mac OS X 10.4.x (Tiger), Mac OS X 10.5.x (Leopard), Mac OS X 10.6.x (Snow Leopard), OS X Lion, and QuickTime 7. It works with PowerPC and Intel based Macs. Unless you are ...

FFmpeg should be able to do this - assuming you don't mind getting down with the command line (there may be some GUI options out there too possibly). My Olympus E-P3 produces .MTS files - I assume they're similar (AVC/AC3 in a Blu-Ray Video wrapper). I ran the following command: ffmpeg -i 00001.MTS -vcodec copy -acodec copy -f mp4 00001.mp4 That just ...

Adobe Premiere Elements is like $80 and does all that including stabilization. I use Premiere pro on my main comp and you elements on my backup computer since I couldn't afford another copy. It's not free but I've looked for free editors and you won't find anything free that does stabilization. Elements project files can be imported in to Premiere Pro so ...

I spent my eveening but finally found a working software. That's not a freeware :( 69 boxes, but it works so I'll buy it. This is Wondershare Video Converter Ultimate. Don't hesitate to edit this answer if you feel that my answer is too spammy. Happy converting

For amateur events, SDI may be overkill compared to using simple Component. The key for long runs is to separate the various components so that they don't degrade. There is a similar question here about long distance runs. As for HDMI to SDI, there should be no quality loss compared to HDMI as both are digital formats supporting full uncompressed HD ...

If you select your clip and go to the Clip menu, then choose Analyse Content, Premiere will attempt to identify speakers and even attempt to dictate what is being said. You can assist this analysis by providing a script file to it by adding either an Adobe Story Script file or a TXT file to the Reference Script option. I don't have any experience with how ...

Amazingly, the best place to start with a question like this is Youtube.

Please note this is UK legislation After some research I found the following in a Government consultation paper: From MODERNISING COPYRIGHT: A modern, robust and flexible framework http://www.ipo.gov.uk/response-2011-copyright-final.pdf There is a clear mismatch between what is permitted by law and the type of private copying that most people think is ...

VGA is RGBUV (horizontal and vertical sync) not YPbPr so without active adapting hardware, it isn't going to work. The formats are not compatible as the addressing information is missing. You might be able to find a dual mode monitor that has support for both formats on the connector (some video mixers do for example), but it would be luck of the draw ...

While it can't go direct to H.264, VirtualDub I believe can work with Vfw codecs and can transcode to something more compatible with your other tools. I don't know if Quicktime for Windows supports Vfw codecs or not, but I do believe the Pro version of Quicktime supports H.264 encoding. If you have Adobe Media Encoder, it would also easily do what you ...

What you are looking for is called a Screen Capture program or Screen Cast program. A quick Google search turned up gtk-recordMyDesktop as an option that should work for your purposes and appears to be built in to Ubuntu. This was the site I found that explained more detail on how it is used. I personally have no experience working with Ubuntu, let alone ...

If you want something pretty standard and with good quality with DV. The most important thin, whatever the codec you choose, configure it for an interlaced source (since VHS signal is interlaced). If you don't you will end up with a digitized file that will need more space and have much lower quality.

VHS is already highly 'compressed', so capturing to an uncompressed format is likely overkill. For your purposes MJPEG with a reasonably high quality setting will preserve all your options and shouldn't degrade the images any further than VHS already has. MJPEG goes by other names -- the idea is that it's all "I-frames". It is a lossy codec, but there are ...

Have you tried using Quicktime Pro version 7? It's what I usually use for file conversions. It costs about £20 / $30. http://store.apple.com/uk/product/D3380Z/A/quicktime-7-pro-for-mac-os-x Open your file. Go to the file menu, and select Export Choose your format, e.g. Quicktime Movie with ProRes 422 codec at 30 fps.

The worst part of transferring old VHS to DVD is that it has to be done in real time as VHS is linear access and analog. Here are two ways I know of that work. One will eat your time the other will eat your wallet. 1) for about $35 or less you can get a transfer device which connects the output of your VHS machine into a USB interface to your computer. ...

You can download a FREE 30 trail version of Vegas Pro 11 from Sony. http://www.sonycreativesoftware.com/download/trials/vegaspro I've have Vegas Pro 10 and I have used these features: Stabilize, Convert resolution down to 720p, and convert (render) to MP4. I never convert resolution up, it just looks terrible (see my comments above). By "Crop to ...

I would recommend downloading the trial version of Adobe Premiere Pro, and cutting the videos together in there. The trial lasts 30 days which should be enough to get the job done.. Premiere Pro can take almost any file you throw at it (so you can leave all your videos in their original format). This way you wont be loosing any quality by converting your ...
