Well, let's say I have this picture: https://dl.dropboxusercontent.com/u/14586156/Z_Root/Clipboard01.png Let's assume I want to change all the gray color in this picture to plain black. Is there a command to have imagemagick change all grey of this image (preferableby using grey [Hex: C8C8C8] to bla...

Well even if I use this command (modified bitrate):
I still get a avi file with horrible quality. Not being comparable to the source stills used.

So… how do I have to change this code:
in order to achieve higher bitrate ?

Since the pictures used right "before" the merge are crisp.

By doubled you mean "put side by side ?"

What setting needs to be changed in order to get the picture nonblurry ?

video 1 Birate: 2931 kBit/s (.avi) (1652kBit/s according to FFMPEG, rgb24 instead of yuv420p according to FFMPEG)
video 2 Bitrate: 2931 kBit/s (.avi) (1100KBit/s according to FFMPEG, rgb24 instead of yuv420p according to FFMPEG)

combined Bitrate 200 kBit/s... (.avi)

These didn't come out like I wanted (a small border remains): [spoiler] https://dl.dropboxusercontent.com/u/14586156/stuff/0_PC_Prog_Dev_support/ImageMagick/Rm_blck_border_from_image/orig.png https://dl.dropboxusercontent.com/u/14586156/stuff/0_PC_Prog_Dev_support/ImageMagick/Rm_blck_border_from_ima...

So far so good.

However the end result looks really blurry and pixelated while the end frames "c" look much more crisp ?

Is there anyhting that can be done to help that ?

Ok, trim actually "is" simple enough. Always dazzles me how ImageMagick simplyfies thes processes

I want to crop the picture so only the white area remains.

As simple as possible.

Would be best if the command could be used on all png's in one folder (batch).

Example:



Would be nice to also get an explanation.


Thanks in advance

I seem to have trouble understanding this one.

Lets say I have 1 png in the same folder with said resolution.

What do I have to add to your script in order for it to work (as it seems to do nothing as of yet... maybe I have to adjust the SRC ?)

So let's say I have about 4000~+ images in a folder, all of different resolutions. The task now is to: 1. Find all images with resolution of 256x384 inside the current folder 2. Resize them to 322x480 (if you are fixed on certain image type, let's assume png is the one for the sake of argument) Is t...

However if you don't know the frame number ?

How about reading it from the video and saving it to a variable ?

How do I have to modify this line: for n in $(seq 1 1 500) in order for this to automatically process all frames of the video ? Also: If I have two videos with different framecount - for example they differ by 18 frames. Is there a way to compensate for this. This script actually works. I tried it. ...
