Powerful features

Kdenlive is the most versatile video editor available today:

• Support for a wide range of camcorders and cameras, including:

1. Low resolution camcorder (Raw and AVI DV editing).
2. Mpeg2, mpeg4 and h264 AVCHD (small cameras and camcorders).
3. High resolution camcorder files, including HDV and AVCHD camcorders.
4. Professional camcorders, including XDCAM-HD™ streams, IMX™ (D10) streams, DVCAM (D10) , DVCAM, DVCPRO™, DVCPRO50™ streams and DNxHD™ streams (decoding only, encoding untested). Please note that Kdenlive does not offer the original codecs, but only that we use FFmpeg free software codecs, which can read original streams and sometimes export as well. When you own a camcorder, there is no reason why you should not be able to read your own films.

• Video and audio tracks organized in layers.
• Tools to create, move, crop and delete video clips, audio clips, text clips and image clips.
• Configurable keyboard shortcuts and interface layouts.

• Non-blocking rendering using a rendering separate application. Stop, pause and restart rendering. Continue to work on your project without any possible loss of data.
• Export to standard formats:

1. DV (PAL and NTSC).
2. Mpeg2 (PAL, NTSC and HDV) and AVCHD (HDV).
3. High quality h264.
4. Non-destructive formats.

xmgrace and grace

Grace is a WYSIWYG 2D plotting tool for the X Window System and M*tif. Grace runs on practically any version of Unix-like OS
Homepage: http://plasma-gate.weizmann.ac.il/Grace/
The most important is that batch file
My sample:
********************************

* READ NXY "He-Raja-G01.rate" *
* READ NXY "He-Raja-G02.rate" *
* s0 line color 1 *
* s1 line color 2 *
* s0 legend "ionization" *
* s1 legend "Excitation" *
* PRINT TO "asfdaa.jpg" *
* HARDCOPY DEVICE "JPEG" *
* PRINT *
*********************************

Below samples are from wiki: http://ringo.ams.sunysb.edu/index.php/Xmgrace

Sample Xmgrace input batch file

READ NXY "5M030.rmsd1.txt"
READ NXY "5M030.rmsd2.txt"
s0 line color 1
s1 line color 2
s0 legend "pose1 rmsd"
s1 legend "pose2 rmsd"
title "RMSD"
xaxis label "time (ps)"
yaxis label "RMSD (angstroms)"
PRINT TO "${system}.eps"
DEVICE "EPS" OP "level2"
PRINT

Run Xmgrace with the command

xmgrace -batch temp.bfile -nosafe -hardcopy

where temp.bfile is the name of the batch file nosafe allows xmgrace to write the output eps plot hardcopy means make the plot and exit. Do not show gui.

For high resolution png file output with transperant background: The DEVICE "PNG" DPI dpi does not seem to change anything.

PRINT TO "output.png"
HARDCOPY DEVICE "PNG"
PAGE SIZE 2560, 2048
DEVICE "PNG" FONT ANTIALIASING on
DEVICE "PNG" OP "transparent:on"
DEVICE "PNG" OP "compression:9"
PRINT

Print to jpg

HARDCOPY DEVICE "JPEG"
DEVICE "JPEG" OP "optimize:on"
DEVICE "JPEG" OP "quality:100"
DEVICE "JPEG" OP "smoothing:40"
PRINT TO DEVICE
PRINT TO "testtest.jpg"
