comment Recording and playing video with variable frame rate
The encoder should account for that, variable framerate doesn't mean that you will heavy drops in the frame rate, its usually always around a certain values +-2 fps.

Well there isn't really anything else you can do without violating the specs I guess.

comment Play movie fragments in a loop, optionally in slow motion
Well the final goal is defined to have a specific playback option, it's still an off-topic question even if its involves playing it back in a video editor. user6251 will get better answers at a different SE like softwarerecs.stackexchange.com

Welcome to Video Production SE! This question isn't about producing videos. Questions regarding playback of videos are not on topic here.

comment Lossy output with FFMPEG JPEG 2000
Well with photoshop you can do a batch processing aswell. So that wouldn't be an issue. Fnords JPEG2000 plugin is very feature complete and implents almost all aspects of JPEG2000 there are.

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.

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.
