Creating Screencasts/Technical issues
File Size
[edit | edit source]Before starting a screencast, you want to make sure you will have adequate space to store the final video. It's generally a good idea to have at least double the space you think the resulting video will be.
Controlling Video File Size
[edit | edit source]Not all these options may be available to you when recording and may instead be hard-coded into the software as presets.
- Resolution
- This is the size of your video's width and height in pixels. Generally, more pixels = more memory, so having a larger resolution will result in a larger file size.
- Capture rate
- How often a frame (still picture) is recorded. This is usually denoted in milliseconds (ms). A lower capture rate will result in more frames being captured during a given interval of time.
- Framerate
- This represents the amount of frames played in a given time period. Usually it is denoted with frames-per-second (fps).
- Bitrate
- The maximum amount of data allowed to be recorded at a given time. Usually measured in Kb/S.
- Compression \ Codecs
- The encoding scheme used to store the video.
- Keyframes
- This stands for whole or complete frames.
Easy on the eyes
[edit | edit source]Fullscreen VS region recording. Maintaining a descent file size without sacrificing readability in compression.
Controlling Audio Size
[edit | edit source]- Channels (mono vs stereo)
- If you're just recording your voice from a microphone, mono (single channel) is recommended.
- Frequency
- Measured in Hertz
- Bitrate
- The maximum amount of data allowed to be recorded at a given time. Usually measured in Kb/S.
- Compression
- The encoding scheme used to store the audio data.
