avidemux


Folks,

This is perhaps more of a comment than an actual question. Why is it so unclear how to use avidemux or to do any video stuff ? Why is it that one has to be a rocket scientist of video encoding and YUV whatever and PS A+V + TS and somesuch just in order to cut a part of a VOB file and put it as a mpeg file ? Not to mention being able to put it down using x264. Why is it that just about every tutorial on doing video stuff is loaded with a thick layer of technobabble that scares anyone who simply does not want to get involved in all those details and just want to have some fun doing some video conversions for friends ? Is this for fear of copyright violations that plain instructions are not given ?

"If audio and video are not synced, you can use A/V shift, even in copy mode." - avidemux wiki

That's just about like Chinese to me.

Anyone know of a good web site that gives plain avergae Joe instructions on how to do video stuff using Linux ?

Sorry to sound like a moron, but I'm way too busy with other programming concerns that are not related to audio/video and I'd like to just get some video tasks done. Maybe it's the same complexity in the Windows world, I don't know. Maybe audio/video encoding/decoding is _really_ a rocket scientist thing after all !

Cheers.

It can be.

*They do have a linux specific forum, but it is not all that active. I would expect you could receive just as much help here, but the site does have very good tutorials on video in general.

Editing digital video can make it very difficult to keep the audio and video streams in sync (especially editing mpeg)



I haven't used avidemux a lot, but in general, just mark your start frame and your stop frame, set your output type, and start the job. (In theory) it's pretty simple.

Start avidemux2, open a video file. At the left you will see a column where you can choose which audio/video format to save. At the bottom of the audio section there's a litte checkbox titled "shift". Test some values. For my dvb-t recordings for example -550 ms is fine, but YMMV -- and I have to use it, else the converted file as some significant audio-video-delay, it's just not synchronized without it.

I'm no rocket scientist. I also think this video stuff is overcomplicated. A bunch of formats, another bunch of things I really think are too technical (hit me with I-Frames, B-Frames, Interlacing and so on). I shiver thinking of the day I might consider installing cinelerra from source
