Hi

My overly ambitious plan is to capture sufficient video footage of pipits doing their tail wags, foraging etc, so that we can reliably use these behavioral characteristics to improve our ID skills.

Oh what joy it was to finally see a pipit, and to have a Canon 7D with 400mm lens in hand <!-- s:bouncy: --><img src="{SMILIES_PATH}/bouncy.gif" alt=":bouncy:" title="Enthusiastic" /><!-- s:bouncy: --> So I managed to capture a few seconds of a (what I think is buffy pipit) walking and foraging in full HD!!!

Now for the reality check! A full HD video (even a few seconds worth) is a massive file that is unsuitable to post on a web site etc and further, even at 400mm, the bird is tiny in the frame.

So, is there anybody out there who knows enough about video editing to help with cropping a video (is this possible) and resizing the essentials to a "you tube" size file?

If there are any willing volunteers, I will gladly e-mail you the file to work on, or post it on a free cloud server to download and work on.

Regards,

Mossie

Hi Mossie.

I guess somebody had to be brave enough to post a reply! Firstly, I'm not sure if video clips can be cropped, at least none of the editing software I have offers that function.

In terms of editing software, I have tried a few different ones for the clips from our camcorder which, although not HD, does produce very high quality clips with huge file sizes. A 30 second clip is over 300mb! The software that came with our camcorder (a JVC Everio hard disk recorder) was Cyberlink Power Producer, Power Director and Power DVD. Personally, I'm not keen on them, I don't find them particularly user-friendly. I generally use Nero 7 Premium's 'Nero Vision' for video editing and don't find it too difficult to get to grips with. I've heard good things about U-Lead Video Studio too but haven't tried it.

In terms of file sizes, the easiest way to reduce them to something manageable is to load the clip into one of the aforementioned programs then select 'export'. Usually you will be presented with various options for the format that the exported file will be, such as MPEG, AVI, WMV etc. Some, I think, offer you the options of formats that are web / e-mail friendly. What you need to bear in mind is that reducing the filesize does necessarily involve reducing the video quality. Reducing the frame size is certainly one way that can be achieved but then with small birds at a distance, the smaller frame size is going to make it even more difficult to see the bird! You may need to improve your stalking techniques to get closer to your subjects <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: -->

I hope at least some of that information will be of some use to you. If you need any more help, please feel free to PM me and I'll help out if I can.

Hi Dave,

Your bravery is much appreciated. If you have ever tried to stalk a pipit.... its easier to crop the video frame by frame and stick it all back into a movie <!-- s:biting: --><img src="{SMILIES_PATH}/biting.gif" alt=":biting:" title="Frustration" /><!-- s:biting: --> Perhaps I should have a go at posting this on another forum... but then I would have to explain what a pipit is, and why on earth anybody would want to do this <!-- s:bomb: --><img src="{SMILIES_PATH}/bomb.gif" alt=":bomb:" title="Frustration" /><!-- s:bomb: -->
