Reduce video file size
The maximum file size you can submit to Kaltura is 1.8GB. While this is OK for short HD clips recorded on your mobile, you might hit the upload limit for longer videos.
If you used a video editor such as iMovie or Movie Maker, the best thing you can do is to change the settings to a lower quality when you export.
Alternatively, you could also use a program to transcode the video file you’ve already got. Here’s how to do this using Handbrake, which is open source. The screenshots below are from Windows, but the OS X version looks and behaves in a similar way.
Open the video file
You can drag and drop a video file onto the Handbrake window, or you can select one:
Select a destination
Click Browse to select where to save the converted file. If you’ll be doing more conversions in future, you can set the default location in Handbrake’s options.
You can tell Handbrake to automatically select a destination folder each time
Click Tools, Options, and then Output Files where you can set the default directory to save the converted files.
Select a preset
- On the presets list, click iPad – you might need to expand the Devices list if it isn’t already.
- Click on the Video tab, and select Same as source from the Framerate (FPS) dropdown
This may take a while depending on the type & length of video, and the speed of your computer. You might want to go and make a cup of tea ☕.
When the encode is finished, you should have a much smaller file which you will be able to upload to Kaltura. The original file, from a digital camera, is on the left and the file transcoded in Handbrake is on the right
If you’re converting videos from your mobile phones, you might not get the same levels of compression (as mobiles already compress their video), but it should be enough for you to successfully upload to Kaltura.
