Anyone knows of a free bulk image downloader? Preferably web-based. I searched the thread but the links I found were dead.

Are we talking for imagehosts, galleries on legit websites or both?

Looking for a program to cut mkv / mp4 videos without affecting the quality specially hd videos

For more accurate editing, AVIdemux will do the job.

For more general raw cuts, mkvmergegui will do the trick

AVIdemux always stops , and in mkvmergegui i can't find a way to cut a specific part .. any help ?!

You can use "mkvmerge GUI" to cut parts out of .mkv files without re-encoding.
It's not that comfortable to use but it should do the job on almost every .mkv file.

You have to do the following:

Download mkvtoolnix from [hxxp://www.bunkus.org/videotools/mkvtoolnix/downloads.html#windows]
I'd recommend the .7zip archive, so you don't have to install anything
Start the mmg.exe
Add your .mkv file within the "Input" tab
Also, specify the output file name
Go to the "Global" tab and select "Enable splitting... after timecodes"
Enter the timecodes (hh:mm:ss), where you want to split the file (separated by commas)
You have to find out the timecodes by playing the .mkv in your media player
Hit "Start muxing" if you're ready


Well, it's not the best solution but if you only need a few parts it should work fine this way.
Since mkvmerge just splits the video, you have to delete the not needed parts.
