Tutorial - Stock video footage prepare/export as Valid Quicktime files
Stock footage business has become a major income method for lot of video artists, producers, animators. Some people are doing this as a hobby while making passive income from it. I'm too into video animation and shooting, and have uploaded few videos myself too.
This is one of best selling stock footage here on dremstime.com (not mine.. ha..ha..)
If you are a new video producer or If you are new to stock video footage business, then you may be having confusion with correct requirement for footage clip submissions. So I would like to share my knowledge on the area.
In here, I'm going to discuss some brief details about stock footage and export quicktime mov files with several software. (Adobe Premier Pro, After Effect, QuickTime Pro)
What is the basic technical requirement of stock footage?
- Quicktime MOV format (.mov) compressed using PhotoJPEG or Motion-JPEG (MJPEG) codecs.
** PhotoJPEG codec for Progressive scan video files.
** Motion-JPEG codec for Interlaced scan video files.
- Compression - 95%, Best
- Audio. Any ambient sound that is relevant for the clip or voices are acceptable. But for Animations sound should be mute.
Does my camera able to shoot quality enough videos?
First, Let me start by explaining about Progressive and Interlace videos. Now as you know.. Video means "Sequence of images". That means video is made by sequence of images presented along with time. So..25 or 30 images per second etc. Now these two method represent how the each image is recorded to the camera.
- Now Progressive Scan video capture each full frame and store or display it. If the frame rate is 30, then It has full 30 frames recorded per second. Progressive Scan method can record higher data quality. If you see something like this " HD 1080p " , here "p" means "Progressive", then you should know that it's a Progressive recording format.
- Interlaced Scan method is using at TV broadcaster systems. It is made for less data quality and easy process. On this method, if the frame rate is 30, then it has total 60 frames which are odd and even lines and blending elements from two adjacent frames one after the other, splicing odd and even lines together to form each frame. So when it displays it becomes 30 full frames. So know that Interlaced scan method means less quality than Progressive Scan method. This represent as "HD 1080i ".
So knowing the Progressive or Interlaced is useful when deciding the compressing method for Quicktime MOV. Now a days most of camera comes with different video resolutions recording options as well as option to select Progressive or Interlaced as well.
These are the main basic video resolutions and frame rates which might be available on your camera. If does you are good to go. :)
Full HD - 1080p, 1080i / (1920x1080) / 23.98, 24, 25, 29.97, 30fps
HD - 720p / (1280x720) / 23.98, 24, 25, 29.97, 30fps
PAL 720x576 / 25fps
NTSC 720x480 / 29.97fps
all above video sizes are accepted by dreamstime as well any stock site.
Why QuickTime MOV(PhotoJPEG/MotionJPEG) as stock footage ?
Now you may be wondering, what is so special about this QuickTime mov format.
This mov video format is the container for video information. Think it as a special kind of box. Then PhotoJPEG/MotionJPEG means the codec. Codec, think it as the pattern that you would fill if you given small bottles inside of the box. So you can use different patterns to achieve different quality, safe level. So if you used a different pattern that might be different Codec and compression.
So If you used PhotoJPEG or MotionJPEG codec with QuickTime MOV file format, then you can achieve very best video quality and can preserve highest original quality of the video. When you using this format, data loss is very low, so you can have highest quality files for your customer. That's why stock agencies ask for QuickTime MOV files. (for your knowledge this compression type called "Intraframe").
If you visit Dreamstime video requirement page, this concept explain there too in great detail.
Which software to use for editing and export valid QuickTime MOV files?
Now to the real deal. As you probably know, we can't shoot exact correct footage with correct duration. So surely we'll have to edit, cut, trim videos and select the best part as a stock footage and export it. There are lot of pro video editing software like Adobe Premier Pro, Final Cut Pro, AVID, Sony Vegas. As well as there are consumer level editing software like iMovie, Quicktime 7 Pro etc. So I will show you how to export QuickTime MOV files from few of above mentioned software.
Now Here I've three software with explaning how to export QuickTime MOV files with correct Setting. Appologies, but I'm linking you to my external site with complete tutorial with screenshot.
(I find a way , but..it seems we cannot upload any screenshot images to blog. )
If you follow-up above tutes, this is the approved footage file here on dreramstime which I submitted.
Good Luck with your stock footage business.
I'll be happy to help with any question.
