comment Combine multiple videos as separate streams in one mkv file
Not sure, I'm not an expert, just a happy Googler, but you could experiment with the -ss option. Please edit your question with the addition and add an answer yourself including the ffmpeg code if you find that it works. This will help future visitors.

comment Linux command-line option to do video lens correction?
On the Photo.SE site a very similar question was asked and answered (by me). While not directly applicable to a video file, I think you should fairly easily be able to convert video to a series of images (with e.g. ffmpeg), apply the correction to the images and combine everything back to a video again.

You could use ffmpeg. Here a similar question is asked only with another video and audio format.

comment Mix Voice to Video without losing video quality
As you're in a hurry it's helpful to give as much information as possible such that people can help you fast and don't have to guess. What OS are you on? What is the format of the video file? What is the format of the audio file? How did you sync the audio and video recording?

Do the layers maybe use a certain blending mode in Photoshop which is not supported in FCPX?

comment Correcting exposure flickering in time-lapse footage (in After Effects)
@FriendofKim Ok, I see. I understand you point that cameras are not accurate, but a big part of your answer bases itself on this "fact" so it's a pity that you don't have the source anymore.

comment Correcting exposure flickering in time-lapse footage (in After Effects)
This leads to an accuracy of maximum 96 % I don't understand where you got the numbers. Do you have a source for that?

comment Sources to learn more about Audio/Video compression, codecs, algorithms etc.
This answer is really general and doesn't really help the OP. Could you maybe edit it to make it more specific? Maybe add links to relevant Wikipedia pages.

comment Is There A Fraps Alternative That Records Different Audio Sources To Different Tracks
Hi and welcome to Video.SE. Right now the question is not very clear. Could you clarify (by using the edit function) what you mean by different audio sources? I would understand it in a regular audio recording setup, but as Fraps is used to record gameplay I'm not sure what is meant. Do you maybe mean the microphone and the game-audio?

comment How to correct shadows when parts are too bright and other parts too dark?
Why is it tedious to use region based filters (I assume you mean a mask)? By this video is amateur, do you mean that the footage is very shaky?

comment What is the most lossless way to rip a laserdisc to a Mac?
Does the guide cover (part) of your question? If not, please specify which part is not clear. If it does I guess the guide is your answer and I can post it as such.

comment How to achieve this kind of masks and transitions
You're asking quite some things in one question. Could you please ask every question separately? This keeps the site organised and enables people to answer one question, even if they don't know answers to the other questions. You could for example ask four questions about the subjects: -Intro, -Subtitle, -Transitions -Color correction.

Here's a guide to get you started by the way. It covers the hardware aspect pretty well.
