comment Lossy output with FFMPEG JPEG 2000
Also if you really just want to compress a few images and videos with jpeg2000 and don't need a command line you can use j2k from fnord. Its free and integrates into Photoshop, After Effects and Premiere (if you happen to own any of these, you can also use a free trial). fnordware.com/j2k

What is the issue with them being RGB? That doesn't affect the compression in any way, doesn't matter what color space your source has, OpenJPEG will decode them and use the color space provided by you for encoding. Almost all of the listed formats support 16bit color, much more than HEVC even supports.

Btw. if you just want to compare JPEG2000 implementations I recommend to just download the OpenJPEG binary directly and work with that, afaik FFmpeg only partially implents it. You will have far more options and better documentation: code.google.com/p/openjpeg/wiki/Downloads?tm=2

The -profile:v flag mentioned in the blog post might help you. It applys specific encoding profiles that are also found in other encoders. I cant find it in the documentation specific to JPEG2000, to know which profile is which you may have to look into the source.

+1 for reducing noise and specifically mentioning shadows.

comment After Effects Not Rendering Transparency
Sure using a png sequence or gif will both work in all browsers. If its just a single color or a small gradient on your "write out" effect a gif would be sufficent. You can import your rendered video into Photoshop and export it from there to a GIF. Photoshop Export to Web has more control over the GIF quality than Adobe Media Encoder. Though if you have a soft edge GIF will be a bad choice, it only has a 1bit alpha. You probably also experience some aliasing with GIF if you have lots of round edges.

comment After Effects - Recreate a “distortion” or a special Radial Blur effect / Slowly pitch sound down
Well you should use them in conjunction not either the blur or the ripple/displace, the blur in Dishonered isn't just a static blur, it floating and distorting the picture, for that you need something to displace the picture. To "slow down" sound you can't user After Effects, thats a whole other question for sound.stackexchange.com.

comment I only have the .mp4 files from a Sony XDCAM EX shoot, is there a way I can still convert them for use in AfterEffects on Windows?
Though unlikely, the camera would shoot not in spec with the MP4 format if thats the case. Every codec supported by MP4 is supported by After Effects natively.

comment What is good software for video editing under Linux?
Its actually a suprisingly solid tool despite the kind of boring website for it. NLE's for Linux have been pretty crap in the past. Would recommend it over a lot of free tools for windows.

He also searches for Linux tools and many are for Linux.

Possible duplicate: video.stackexchange.com/questions/2274/… Though its not asking specifically for Linux and mainly for windows.

comment What do you call the video effect where water looks like it's standing still when filmed
Do you just seek for the word for it or an explanation why this happens?

comment How can I convert .MTS file (AVCHD) to .mp4 by ffmpeg without re-encoding H264 video stream?
It's rather unlikely that avconv will do a different job for him. avconv is a fork of ffmpeg and ffmpeg is merging a lot of commits from the avconv project into ffmpeg, major bugs fixes like that would likely be present in ffmpeg.

comment WAX - How do I make it so the PiP can go anywhere?
not really an answer to your question but may I suggest using Lightworks. It's a free modern NLE with support of many formats and modern user interface. You will get a lot more support and tutorials for this tool aswell. lwks.com

comment Video for Windows Codec x264 and VP80
GStreamer is great for developing OpenSource or even commercial apps with video functionality but its not that super duber easy to use, though if you are willing to give it a try it definitely offers great features, is pretty robust and in the end not THAT hard to use. You could also use native C++ code in your C# app to use the latest version of GStreamer. E: Actually it seems the continued development, the latest C# bindings are from 2014! Last time I checked the latest code was from 2009.

Very weird issue you have there. One thing you could try besides looking what commands this tool used internally is to omit the time constrain (´-t 60´). I'm somewhat believing that cutting h264 like that could cause problems without transcoding. FFmpeg could have just cut in the middle of some P or B frames that dont decode without an I frame which may have caused the video to corrupt depending on how a player would handle such a case.

comment After Adding a few Clips to the timeline, audio is no longer imported?
Can you try import clips from a different source and see if they have the same error? Also a Mediainfo output would be helpful. mediaarea.net/en/MediaInfo

Could you try the tool Mediainfo instead of ffprobe and see what is says about the framerate? mediaarea.net/en/MediaInfo
