DL.TV Wallpaper Remembered

January 30, 2015

From DL.TV Episode #160

Ah, the good old days!

After ZDTV/TechTV vanished, geeks were left with a knowledge void that left us sad and despondent.  Until that is, when DL.TV was launched.

Hosts Robert Heron (left) and Patrick Norton (right), pictured above in episode 160, entertained and informed a large fan following on this free webcasting network.  Their insightful musings about the current state of all things technological was a much-needed relief.

Relive those glory days by displaying these enhanced original computer wallpapers:

DL.TV, however, now only exists in archives and on YouTube.  And, of course, in the minds and hearts of the fans who still remember.



The TWiT Logo Wallpaper

Leo Laporte is The Tech Guy

The TWiT Network uses this image as a billboard behind Leo Laporte on a dedicated Skype computer when no video calls are displayed.

This image is also employed as an editor’s mark during video productions.  The logo screen is inserted by the engineer to allow the video editor to quickly locate and identify segments that need to be “spliced’ into the finalized program.

Tweaking OGMRip Settings

January 12, 2015

OMGRip: Main GUI Screen

OGMRip is a Linux only DVD transcoder that allows users to create a wide variety of different file types.  The program works best as an AVI encoder, incorporating the XviD/DivX codecs…

With a few modifications.

Edit > Profiles > DivX for Standalone Player:

OMGRip: Edit Profiles Dialog Box

You can tweak the settings for any output file format by selecting the desired combination of audio/video codecs and then click on the Edit button.

The General Tab:

OMGRip: Edit Profiles General Tab (Constant quantizer)

The default settings are adequate for the task, but by changing the encoding method to “Constant quantizer” you have more control over the quality and size of the completed file.

The OGMRip User Manual states:

Constant quantizer: Also called constant quality, this encoding method gives very high quality videos but very big files. A lower quantizer gives a better result.

You don’t get something for nothing.  The lower the quantizer number, the higher the quality and the bigger the file size.  The higher the number, the lower the quality and the smaller the file size.

  • 0 to 2 = higher quality, larger file size.
  • 3 or 4 = good quality, medium file size
  • 5 or 6 = lower quality, smaller file size

The middle setting is a good compromise between quality and file size.

The Video Tab:

OMGRip: Edit Profiles Video Tab (Xvid Extreme)

XviD is the open source version of DivX.  As a result, the two codecs are interchangeable.

Many DVD and Blu-ray players on the market today come with these codecs pre-installed.  These machines can play a DivX/XviD encoded AVI file that is burned to a blank single-layer or dual-layer DVD.  This allows you to store and access multiple programs on just one disc.

The Audio Tab:

OMGRip: Edit Profiles Audio Tab (MP3)

MP3 is the preferred method for audio encoding.  However, the audio track on some DVD discs may not be compatible with this encoding process.

If the audio in the finished product sounds sped up and out of sync, you can do a “passthru” and embed the original sound files directly into the outputted file.

OMGRip: Edit Profiles Audio Tab (AC3 or DTS)

This method gives you less control over the audio track, but still sounds good.

One of the major advantages to using AVI over other file formats is the warmer, more film-like quality that is produced.  It’s an excellent choice for older movies or television programs.

Linux offers a wealth of free programs, like OGMRip, as an incentive to try this free and open source operating system.  You’ve got nothing to lose and a world of opportunity to gain!
