"The single reason"? So I'm control of the keyboard of all participants in this thread? There was in fact no response necessary to this thread at all, other than Carl's original email, which actually gave an answer to the person's question. All other comments could be deleted with no loss to the thread. Patrick's comment had no relevance at all to the actual question. > Someone who took the time to read the new user's question asked a polite > "Please include your command" request, that is all.

These are all excuses you're inventing to play devil's advocate, which has nothing to do with actual thread. The reply in question was just your typical, ordinary, everyday "OMG SOMEONE BROKE A RULE, MUST REMIND OF RULES" response--as Carl's followup proved. I ask again: how does giving the command line used help in any way solving the user's problem, in this particular circumstance? Interestingly, Carl didn't even bother asking for the command line in his own response. Seems he didn't need that information to actually answer the question. > Even if your messages were intended to increase friendliness to new users, > they had the opposite effect due to how confrontational they were.

So you wouldn't be at all bothered at being called an idiot by a certain loser, because your subject line wasn't so great, but would instead be bothered by the guy actually sticking up for your noob self? > My 2¢, > Tom Thanks for your input, Tom.

Re: [FFmpeg-user] New user question
> And how would that help this situation in any way? Do you have anything better to do than make snarky comments? The guy posted an open ended question without any context. And yes having the command makes a difference. I know eff all about HAP and perhaps had he included his command I would have had some more context. You could have ignored the thread, instead of cheapening the discourse.

Ironically the single reason this thread has devolved into personal attacks and irrelevance to the original question is your own contributions. Someone who took the time to read the new user's question asked a polite "Please include your command" request, that is all. Maybe they wanted to test the command on their own system for comparison; maybe they had one of the reasons Carl mentioned. Even if your messages were intended to increase friendliness to new users, they had the opposite effect due to how confrontational they were.

[FFmpeg-user] Frame rate discrepancy
Hi all, I'm pulling video off a capture card for a surveillance application. I use the -t option to ffmpeg to record a 6 hour segment of video, then stop and start another segment.
