Video file size can be tricky and the concept of reducing video file size has many technical variables associated with it. You may want to reduce file size to more easily send to your co-workers, or complete your upload to YouTube quicker. It can be hard to know where to start when trying to reduce file size. Below we’ve put together some helpful information to get you started on your file reduction journey!
From Camtasia for Windows/Mac supported file formats list, we can see that the Camtasia Studio for Windows only support to import MP4 files enocded with H.264/AVC at no more than 30 frames per second. As for Camtasia Editor for Mac, you are also highly recommended to use the MP4/H.264 (AVC) formats for importing. The TechSmith Screen Codec v2 (TSC2) is included with Camtasia. Download this decoder to play an AVI or MOV file that is encoded with TSC2 on a system where Camtasia is not installed.
Video Format and File Type
**If you’re new to these concepts, please don’t stop reading just because we use a lot of jargon, we will try to explain each, and by following the associated links, you may also better comprehend each one.**
There are many different video formats you could export your finished video into. To help you understand video codecs and containers we wrote an in depth post about the differences of video files types. Codecs encode or compress streams of data for storage, playback and video editing on a variety of platforms. Learn more about codecs here. You may have heard of the h.264 codec (you may not have, but hang in there). This codec produces an MP4, which typically delivers the best quality, with smallest file size. Because of this, MP4 is very popular for web-based delivery including YouTube, Facebook, Twitter and Instagram. To help you not worry too much about file size, we’ve created Camtasia and Snagit video outputs to default to the MP4 file type, and will recommend MP4 in the majority of cases for online sharing.
Other common video file types include:
- .MOV (Apple Quicktime Movie)
- .AVI (Audio Video Interleave – Microsoft)
- .WMV (Windows Media Video – Microsoft)
- .FLV (Flash Video Format)
And many more! You can learn all about the different video file types listed above by reading this article.
Takeaway: Use the MP4 file type to keep quality and reduce file size.
Video Dimensions (in pixels)
The resolution of a video determines the size in height and width that the video will be created in. Resolution is defined by the number of horizontal lines the video has from top to bottom. Larger resolution videos will dramatically increase file size. As you can imagine a video that is 1920 x 1080 (1080p) will have a larger file size than a video that is 1280 x 720 (720p). A 1080p video has more horizontal lines (more information), thus making the video file size larger. Some screen recordings taken on high density displays can even produce videos at or above 3840 pixels × 2160 (4k). High density displays have millions of pixels and thousands of horizontal lines; even more information! Don’t record your entire screen unless it’s really necessary, or consider using zoom and pan actions while editing your video. This way you can scale the video down, but still focus the viewer’s attention on a specific portion of the screen. In Camtasia, you can change the project settings to produce your video at your desired resolution.
Takeaway: Export at a suitable resolution for your project. Exporting at 720p or 1080p will work for most people.
How Much Action Is In Your Video?
If you have a lot of transitions (wipes, blurs, animations) along with fast-paced imagery, your file will be larger. For example, recording a fairly static presentation of slides (less action) will yield a smaller file size than recording some on-screen live video (more action). Using the MP4 video format will also help mitigate some of the file size issues associated with movement, as MP4 is highly efficient in this regard.
Takeaway: Adding lots of movement and transitions will cause your file to be larger.
Sometimes audio can create larger file sizes, though most of the time recording devices and software will compress your audio so as not to create large file sizes. In addition, it is very rare that uncompressed audio is going to make an audible difference to your viewers. After you’re done editing your video, make sure to export with compressed audio. Default outputs for Camtasia and Snagit MP4 format uses AAC audio compression which has a good combination of sound quality and file size.
Takeaway: Compress your audio on export. It’s rare to need uncompressed audio in most projects. Take a look at our audio best practices.
Frame Rate (FPS)
What is frame rate? Glad you asked! For an in-depth description, take a look at the beginners guide to frame rate. The short answer is that frame rate indicates how many frames (think: pictures) are shown per second to the viewer. Most films are shot at 24 fps. Home videos and camcorders typically default to 30 fps. Which is better? That’s a subjective question and depends on your intended audience. Are you aiming for a video look, or a cinematic look? The custom production settings in Camtasia allow for between 1 and 30 frames per second (fps). While the default, 30 fps, is standard for video, if you’re looking to get more cinematic you can lower it to 24 fps. A higher frame rate will often times create a larger file size when you export.
Takeaway: Use the frame rate that is right for your project. Know that higher frame rates will cause slightly larger videos.
Hopefully these tips will help you reduce the file size of your video. If you’re ready to try it yourself, download Camtasia! Let us know how it goes on Facebook or Twitter!
