comment How to add my logo for the first 30 seconds in a video with ffmpeg?
@Rajib: The reason for the -framerate and -loop for a still image is so that the fade out will work. If there is only a single frame then it has no way to fade out over a 1 second interval. Ideally it should be the same frame rate as the video so that the fade will be as smooth as possible.

@iwocan: Sorry, add -shortest (or -t and the desired duration) before the output file name. Otherwise the png will be looped forever.

comment Creating a movie from images using ffmpeg but getting only one frame
The second command should work. Are your files named input-00001.png, input-00002.png, etc.? What does the output from ffmpeg say?

comment dividing a video clip by 4 areas
@Saeid87: It's working for me. You can also specify numbers if you know the width and height.

comment Converted MP4 not playing in Chrome
MP4 is a container and can contain video and audio using various codecs. In VLC choose Media Information from the menu, click on Codec Details and expand the streams. Verify that the video codec is H.264.

comment Converting avi to mov (pro res format) using ffmpeg
Looks ok, although normally the frame rate (-r) is specified in the container and you shouldn't need to change it. You shouldn't need to set the number of samples per audio packet either. What is the issue that you are encountering?

comment Put loudness of many video files to the same level
Are you using a program to edit/encode the videos? If so then look for a normalize option (ideally EBU R128 loudness normalization) in that program. If you don't want to re-encode anything, many formats have a way to add a tag that asks the player to adjust the gain by a specified amount.
