From http://www.ffmpeg.org/faq.html: If you have large number of pictures to rename, you can use the following command to ease the burden. The command, using the bourne shell syntax, symbolically links all files in the current directory that match *jpg to the ‘/tmp’ directory in the sequence of ‘img001.jpg’, ‘img002.jpg’ and so on. x=1; for i in *jpg; do ...

The production group you refer to has a team of 20 guys ("no girls") and 40 computers. Do you think there is an open source for 20 CGI professionals and 40 computers too? This is a very real production company with a budget to get things done. They have created enough attention to fund the project 'Iron Sky'. No easy task. What you are asking is like this, ...

There are a lot of answers regarding open source on this answer: Good open source Video Editors? If you specifically target Linux I'd suggest Lightworks or Kdenlive. Lightworks isn't open source yet but is announced to be after the mac release is finished. Both a great option for video editing under Linux and fullfill your requirements. Lightworks has only ...

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) ...

The very simple answer is yes - all these tools have open source equivalents...after a fashion. But they haven't had as much development, as there is less money going into them - so you may need to work out alternative ways to create some effects... and that will take more time for skilled people - which costs more than using tools So I reckon @filzilla ...

with ffmpeg 0.11.1 it's as easy as: ffmpeg -f image2 -i %*.png out.avi From the man page, in an example under "Video and Audio file format conversion": When importing an image sequence, -i also supports expanding shell-like wildcard patterns (globbing) internally. To lower the chance of interfering with your actual file names and the shell's glob ...

Besides the workaround in my comment, you should be able to use this syntax from the ffmpeg documentation: ffmpeg -f image2 -pattern_type glob -i *.png out.avi

I would actually suggest the same thing Mulvya suggested. Whenever I've needed to do stuff like this when dealing with 3D animation renderings, I've renamed the files to make them sequential. It's just easier to work with that way in a lot of different software unless you need to preserve the file names for some reason. Total Commander is also a great ...

There are a few things to consider. The MP4 spec was not designed for the playback of high frame rate files, because the files are highly compressed, and limited to using a single core for decompression. Even if you had 12 cores, the file would not decompress any faster. The easiest way to solve your issue is to either encode the MP4 into another codec, or ...

You're on the right track with -crf and x264 (the H.264 encoder), and it should provide the "quality threshold" that you're looking for. CRF is recommended if you want a certain output quality and output file size is of less importance. Conversely, performing a two-pass encode with -b:v is recommend if you are targeting a specific output file size and ...

To make your vector artwork into a playable movie file, it will have to be rendered, and another term for rendering is rasterizing. For example, in printing, a single image is rasterized when a vector image of a page is converted to the tiny dots the printer produces on the page. Digital movies exist in pixel-based raster formats, so each frame of the ...

While it is true that 720p video only has about half the data of a 1080p feed, the other thing you have to realize is that when you push the system beyond it's limit, it may spend a lot of time trying to process frames that it doesn't finish in time. Depending on how the player is configured, it may give up and try to catch up rather than finish rendering ...

Blender has video editing options, and of course, it is free. Check it out.

I was going to recommend Kino which is the one I used when I needed to do that, but according to their web page the project is no longer mantained, so you can either use it the way it is or try the other software that is recommended on their web page: Shotcut, Kdenlive, Flowblade, OpenShot, PiTiVi, LiVES, and LightWorks.

Capturing the video frames in XWD format then converting to PNG yields results that are almost pixel perfect when encoded with ffmpeg. Install xvidcap: mkdir -p $HOME/dev cd $HOME/dev svn checkout svn://svn.code.sf.net/p/xvidcap/code/trunk xvidcap-code cd xvidcap* ./autogen.sh LIBS="-ldl -lX11 -lXext" ./configure --prefix=/usr/local make && sudo ...

The first thing that I noticed is that your camera is delivering yuv422p - which isn't bad in and of itself, but you could try forcing it to yuv420 by adding -pix_fmt yuv420p to your command. (This is nice if you ever plan on displaying your video on anything that isn't linux.) The second thing that I noticed is that the start times are wildly different - ...

This is an issue with your ffmpeg installation. You have a mismatch between the version numbers of the libraries you are trying to use. Most likely, your version of the webm libraries is not built on the same version of ffmpeg as you are using.

Asfbin appears like it might be able to do what you are looking for.

You do need to keep in mind that, there is an entire production team behind that movie, with some money to start. However, a lot of this can be accomplished in Blender. Blender is the free open source 3D content creation suite, available for all major operating systems under the GNU General Public License. Full movies have even been made on Blender, ...

You can't edit FCP project files on Linux for sure. Sorry :)
