===Windows as of 2018===<br />
Today I prefer using [https://handbrake.fr Handbrake] for video shrinking / compression as it work in Windows, Linux and Mac.<br />
<br />
For movies captured by my digital camera or smartphone <br><br />
I use preset "Matroska -> H.265 MKV 720p30" as template and modify <br><br />
Picture -> Height 720 for downscaling to 720pt<br><br />
Video -> Quality 25 for most videos<br><br />
Audio -> 64bit Mono (for camera or telephone videos) <br><br />
(this modifications can be saved as "User Preset" which can be set to default preset)<br />
<br />
Trimming some seconds off the ends is achieved in section "Source" by switching from "Chapters" to "Seconds".<br />
<br />
Rotate<br />
On Filters tab choose Rotate<br />
<br />
===Windows as of 2010===<br />
I like the free windows tool [http://www.pcfreetime.com/ Format Factory]!<br />
<br />
====My Settings====<br />
For compressing the videos taken by my digicam (resolution=640x480px) I usually use the following settings:<br><br />
Video<br />
* container: mkv (or mp4)<br />
* codec: H264 <br />
* bitrate: between 512 and 1024 kbit/s (512kbit/s for 640x480px seems to be enough) <br>(note: 600MB/hour equals 1365kbit/s)<br />
* 2 Pass encoding: True (for better quality, but much longer computing time)<br />
<br />
Audio<br />
* only one channel (=Mono) @ 64kbit/s (as the tiny mic. in the digicam is not able to record real stereo)<br />
* sometimes I even disable the audio channel if there is nothing but noise on it.<br />
<br />
Output Folder -> "Output to source file folder"<br />
<br />
====Rotating the video by 90°====<br />
use the following settings:<br />
* Rotate = Left or Right<br />
* (AspectRatio=4:3) was needed in earlier versions, now use '''Automatic'''<br />
<br />
<br />
====Beispiele====<br />
16:9, FullHD: 1920x1080 (oder auch 1280x720) schrumpfen auf 800x450?<br />
Video Size: 800x450<br />
Aspect Ratio: 16:9<br />
<br />
====My Format Factory Profiles====<br />
Here are my custom profiles, that can be found at <br />
c:\Users\...\Documents\FormatFactory\VideoCustom\<br />

h264, 512kbit, mono, rotate (one has to set the aspect ratio by hand!)<br />
Type=MP4<br />
<br />
VideoCodec=AVC(H264)<br />
VideoBitrate=512000<br />
Width=0<br />
Height=0<br />
FPS=0.000<br />

AudioBitrate=64000<br />
SampleRate=0<br />
Channel=1<br />
Volume=0<br />
<br />

<br />
mute instead of mono:<br />
AudioCodec=AAC<br />
AudioBitrate=0<br />
SampleRate=0<br />
Channel=0<br />
Volume=0<br />
(It turned out, that FF version 2.50 does ignore the Channel=0 setting, so you habe to disable audio in the dialog)</div>Torben
