Time-lapse Photography with Linux

INTRODUCTION:

Before I really start, I want to point out that there are simple mobile apps out there that will help you do time-lapse videos with your mobile phone and encode it all on the fly! So if you just want to do time-lapse videos as simple as possible, for fun and you don't intend to sell your work, then stick to those apps, they are OK. Otherwise if you are curious or really want to learn how to do it and sell them then read on...

Some patience will be required, depending on the amount of quality you are trying to achieve. I do time-lapses in a more semi-pro level which I sell in stock media sites such as pond5.com or for direct clients who need to re-edit the encoded video to have it assembled with other video formats and the final encoded video must have certain quality specs. Also, I am able to edit the individual shots this way such as levels, exposures, colors and some effects at some point of the process.

VirtualBox Bridged Networking and MTU Problem in a Windows Guest

Busting my head (and other valuable parts of my body) getting Bridged networking in virtual WindowsXP (Windows 7 doesn't have this issue) with Linux host because I needed it to have DHCP IP and make it available to my home network, basic websites would load and others would time out. Also accesing the machine via SAMBA would cause errors once in a while. Using standard NAT would work and resolve websites immediately, but the machine would get IP assigned by host machine and would not be seen to the rest of the home network and completely invisible in router.

UPDATE MAY 25, 2012 was on the fast-track-pro.conf file for better understanding of different modes.

UPDATE JUNE 16, 2012 changed kernel configuration in section "PROCESSOR TYPE AND FEATURES" Tickless System (Dynamic Ticks) to enabled, I wasn't thinking right, sorry for that one.

PART I - INTRODUCTION

The Fast Track Pro by M-Audio is a really nice USB Audio interface, although small, it can perform well in a professional environment. I was given one of these a while back by one of my best web design clients and good friend.

The basic specs on this device are:

• 24-bit/96kHz audio interface with dual mic/instrument preamps
• Balanced/unbalanced analog I/O
• S/PDIF coaxial; MIDI I/O
• ¼” headphone output with level control and A/B source switch
