I use adobe premiere elements 7 for editing video.  Have read some complaints about version 8 though.  It's fairly easy to use, I did look at some youtube tutorials to help when I started.

Don't know if your camera is good enough, have you tried searching on Pond5 to see if anyone uses your camera?  I would just upload 1 clip and see if it is accepted.

Encode your video in QuickTime .MOV format using the "PhotoJPEG" codec at 85% to 95% and remove the audio track.  That is supported everywhere.

You can just do it with QuickTime if you have Pro version.  You might try the free trial of Sony Vegas, it's fully functional for 30-days.  Or search for MPEG Streamclip which is used by many hobbyist stock footage people.

The biggest advice I can give you with footage is BE PATIENT.  It can takes months sometimes for your first sale, depending on how saturated the subject is for your clip.

Hope you don't mind if I jump in your thread to ask some beginner questions also.

Is there a general rule of thumb for length of the clip?

Will a simple keyword search show how saturated a subject is?

Is it best to leave the clips in original format for buyer to decide or should they be graded for maximum effectiveness?

Is shooting in anamorphic an acceptable format?

I know obviously branded objects are one to look out for but what about larger objects like cars, boats, houses, buildings?  Say i wanted to shoot something luxurious and shot a ferrari, avoiding the obvious badges, because everyone knows what a ferrari looks like, will there be an issue?  I see it in music video clips all the time, do they have to get release forms for that from manufacturer even though it is owned by someone?

Same question applies to say taking people shots and they are wearing branded clothes, shoes, etc...does the rules differ because it is video stock rather than print stock?

Cheers.

i had tried to consolidate summary i got from few websites about footage format..

Film clips that are uploaded with the PAL standard of 25fps are also fine.

The technical requirements regarding uploading content are easy to follow. Currently, we accept HD and DV broadcast quality content with 16:9 aspect ratio in a Quicktime .MOV file container format and the most relevant codecs: PhotoJPEG, DVCPro 25/50/100, ProRes HQ, HDV, XDCAM, IMX50, DNx and DNxHD. Our system does not accept .avi containers. If your content constitutes a different codec, please contact us and we will try to accomodate your needs. The minimum resolution requirements is as follows:  720 x 576 (if anamorphic) or 1024 x 576 square pixels in PAL (25fps) or 720 x 486 (if anamorphic) or 864 x 486 square pixels in NTSC (30fps). Furthermore, each individual clip must have a duration of at least 2 seconds, and should not be longer than 60 seconds. In addition, the file may not exceed 750 MB. If any of these technical requirements are not fulfilled, you work will automatically be denied.

I don't think buyers are looking for long clips in particular. Mostly, unless the length is very specific to the essence of the clip, 10 - 15 seconds is fine.

Keyword in a couple of the most popular combinations and read the results carefully. Look at the top and bottom of each page . This will give you an idea of the quality of the category if you examine it carefully. Do the shots with some production value indeed sell? When do the downloads and views stop? Can you compete in this category with a new angle on the image? For an interesting interview addressing some of these research questions see this my interview at www.stockvideoseller.com/public_html/interviews-2/bob-davies-picworkflow-and-.html

For my particular take on format see www.stockvideoseller.com/public_html/topics/3-the-universal-formats-wha.html. In short, why not streamline workflow and offer the most easily digestible format for all users, Motion or PhotoJpeg at this point. Animators/graphics may need other formats to maximize sales.

Some sites, perhaps most are conscious of the branding issues, privacy rights issues, etc. Even dogs can be identified from their markings. Numbers on boats, planes, trains and license plates are things to watch out for. Ouch! Pond5 puts the burden on the user and anything goes up, whereas iStock vets the clips for the consumer and you'll get a high number of rejections of reasons you might consider strange on buildings, urbanscapes, etc. Some sites let you mark shot of Times Square with its adverts and swarms of identifiable faces as editorial. See: www.stockvideoseller.com/public_html/topics/editorial-a-different-way-t.html . You are right, it's a mine field. Just have to know where to step.
