Video of last Friday (july 1 2011) mapping in Barataria Bay

[Jeffrey Warren]

With inspiration from Shai Efrati, I compiled the raw imagery from Shannon Dosemagen and LUMCON's mapping last Friday into a video, and uploaded it to YouTube. The original is 4000x3000px, but I can't figure out how to get it in HD on youtube... any suggestions?

It's pretty fun to watch, and is an absolutely great flight.

Hi there Jeff,

I've been on the listserv for some months now, but I have not really been a part of any discussions as I am not in any of the areas that are currently doing work. I am a graduate student at Texas A&M so I'm mainly in College Station or Houston. If there is anyone doing this kind of work in these areas let me know because I would love to gain the skill to obtain aerials in remote locations. 

Anyway, about the HD video onto youtube. Having photos at 4000x3000 is humungous, so you are going to have to cut that down to the largest resolution available which is 1920x1080. The best way I know how to do this is make a script in photoshop that either crops the image to that resolution, or that resizes the original photos to something similar to that resolution and then crops it to exactly 1920x1080. It is pretty easy to make a script (they are called actions in photoshop) by just going to Window-->Actions and then hit record.

Let me know if this helps or if you figured out a different way to do it. I assume you are using Quicktime Pro to make the timelapse?

thanks tyler, I hope you get a chance to hook up with some more folks in Texas.

there's a really fast way to scale down a video and letterbox it to standard HD sizes, if you have quicktime pro-- 

Window--> Show Movie Properties

click on the video track

scale the video down.

File-->Export

the file will already be at the dimensions you scaled it to.

click Settings

chose the aspect ratio of a standard format, and click preserve aspect ratio by using a letterbox, which will add black spacers to the size you want.

Wow! That's quite a peppy video.  I like it! 

I just posted a similar video last week from my work in California on my research YouTube channel: http://youtu.be/BDXoB7fognM  I used an open source program called Photo Film Strip (available at SourceForge.net).

best,
Michele

Thanks for all the feedback - that's a much more understandable way to do the conversion. It looks like YouTube just takes a while to finish the 1080 HD versions, because they're up now; take a look.

For reference, I was using the "mencoder" linux utility with the following options:

mencoder "mf://*.JPG" -mf fps=25 -o output.avi -ovc lavc -lavcopts vcodec=mpeg4 scale=1920:1080:1

but I wasn't sure the scale thing was working. I guess it must've been if the final movie filesize was only 250mb. It takes every file named ANYTHING.JPG in the current folder and creates a movie called "output.avi". I'm going to try running it on every raw data set we have.
