EPD - Instructor Resources - Camtasia 2 Mac Video Settings
TechSmith products Camtasia 2 (Mac Version) and Camtasia Studio 8 (PC version) are frequently used by EPD for producing recorded lectures. This document provides the basic process and settings for exporting MP4 (.mp4) video files on Camtasia 2 for Mac.
Step 1 Confirm Audio Quality
Check the audio at the beginning, the middle, and the slide transitions.
Step 2 Adjust Canvas (if size is lower than 1280x720) - Optional
Check the canvas size that the project was recorded at. It is best to have an HD quality video (720 pixels or higher), which means the canvas size should be 1280x720 or higher. If the video canvas size is lower than that, adjust it up to 1280x720. If it is higher, it can be carefully sized down, but it is not necessary. It is easy to crop out some information when sizing down.
- Make sure to always preserve the aspect ratio to avoid image distortion.
If the dimensions (or canvas size) need to be edited, go to Edit → Adjust Canvas.
Step 3 Advanced Export
Go to Share → Advanced Export and check the settings.
Step 4 Basic File Settings
Use the drop-down list to select "Export to Quicktime MPEG-4". Enter a proper file name and choose where to export the file. Click Options for advanced video settings.
Step 5 Video Settings
H.264 is the widely accepted file codec. 1280x720 is EPD's recommended size. Frame rates should be set as follows, depending on motion in the video. Lowering the frame rate can help reduce the file size in videos with only slides.
- Set as 5 frames per second for PowerPoint slide-based lecture video
- Set as 10-15 frames per second if there are PowerPoint animations in the video
- Set as 30 frames per second for videos with live action, people, movement, etc.
Lowering the data rate can also help reduce the file size in videos with static slides (no live action/movement/animation).
Step 6 Audio Settings
AAC-LC (music) is the recommended format.
Step 7 Streaming Settings
Please follow the recommended settings.
Step 8 Quality Check and View
Check the following to ensure desired product:
- Desired file size (should be small)
Make sure to scrub through the final video to review its audio and video qualityMake sure it sounds goodEnsure no cropping has occurred and that all information is visible in the video
- Ex: A 20 minute slide-based recording should be well under 50MB
