I'm posting on behalf of my colleague who is looking for software with the following characteristics:

- Compatible with Mac OSX v10.7.
- Able to seek video frame-by-frame.
- Able to zoom and pan.
- Compatible with MPEG-2 Transport Stream files (he's working with *.mts files).
- Must be frame-accurate. Specific events at specific times will be recorded from these videos.

Some notes: He's a graduate student and requires the software for research purposes. The ability to edit is not important as he has no need for this, all the software requires is the above characteristics. Converting or demuxing is not feasible. Loss of fidelity is unfavorable and with the volume of media he has it would be a very daunting and time-consuming task.

I'm a Windows user that has software for the same purposes. I use AviSynth (with the AvsPmod frontend) in conjunction with the ffdshow codec and Haali Media Splitter. It does all of the above things without issue. Is there a MacOSX equivalent for my colleague's needs?

There is a Linux port of AviSynth called AvxSynth (https://github.com/avxsynth/avxsynth/wiki). They have a thread on doom9 (http://forum.doom9.org/showthread.php?t=164386).
OS X is able to run many Linux apps using MacPorts (https://en.wikipedia.org/wiki/MacPorts),Fink (https://en.wikipedia.org/wiki/Fink) or Homebrew (https://en.wikipedia.org/wiki/Homebrew_%28package_management_software%29). I've had a quick look but I don't see AvxSynth listed on them but if your friend asks I'm sure it could be ported over.

Would VLC (https://en.wikipedia.org/wiki/VLC_media_player) fit the bill? Or maybe Avidemux (https://en.wikipedia.org/wiki/Avidemux). Or according to Wikipedia Avisynth is a frameserver (https://en.wikipedia.org/wiki/Frameserver) and so is Blender (https://en.wikipedia.org/wiki/Blender_%28software%29)

[Sorry if these ideas are way off the mark, I don't use or know what AviSynth is, I'm just an OS X user trying to help another :-) ]

@Mak0rz, can you post an example 30s clip? (exactly the type that will be used)
