Timelapse video from image sequence

On my Windows machine workflow was pretty simple I shoot images in sRaw2 mode frequent enough to get at least hundred. Then I converted to JPEG with 100% quality and size slightly larger than 1080p frame, usually 2000 px for larger side. I found great free software called PhotoLapse3



I tried to find free tool for Mac that would do the same with no luck. Most of programs, Gawker for example, can create timelapse video from webcam as a source but they cannot accept folder with images as input.  This is not exactly what I need.

I was also Linux user for a while so I know that there are few command line media converters that do excellent video converting job. I decided to try if they can convert from images to video.

First, I tried mencoder.



mencoder "mf://*.jpg" -mf fps=10 -o test.avi -ovc lavc -lavcopts vcodec=msmpeg4v2:vbitrate=800
After playing with different settings, searching for answers on the net I was not able to find combination of parameters that would give me good enough quality.  First example from mencoder documentation did not help. More detailed example of encoding with libavcodec did not help either.



I do not know which step I am doing wrong. Maybe because I am using JPEGs but as far as I know mencoder would not accept TIFFs as input. After all of this trials I gave up on ffmpeg.  I think mencoder with libavcodec option is actually using ffmpeg. Also ffmpeg cannot handle wildcards for specifying input files.  I do not like the idea of renaming files to have sequential numbers in file names.
ffmpeg -r 10 -b 1800 -i %d.jpg test.avi
Results seem to be even worse than from previous attempt.



It's just to much time consuming so maybe I need to pay and something easy to use? Again browsed thru many search pages, lloked at few apps I will not mention cause eventually all seems like a joke when compared to Apple's QuickTime Pro. For just $30 I got tool good enough to make me uninstall all free converters :-)

Let's see how it works with QuickTime Pro (I could actually use TIFFs a input).


I got professional quality video with just couple mouse clicks. I think it is worth all them money I spent.
