Recording and Editing Lectures / Presentations

DMC staff helped to record and edit Fondren Fellows Showcase on April 6, 2017. Below is a summery of recording set up and editing techniques:

Recording:

Equipment:

The camera was mounted on the tripod, the rode shotgun mic was mounted on the camera using the mounting bracket that comes with the camera set. The audio level was between -12db and 0db. Camera recording mode was set to Auto, recording format was AVCHD –> FXP.

The high-pass filter was selected¬† and the audio level switch was set to 0dB since the audio meter on the camera LCD monitor showed the level was good and fell between -12dB and 0dB. If the speaker’s voice is low and the audio meter drops below -12dB when you are monitoring the audio level, you may consider to switch to +20dB to boost recording level. For more information about the Rode Shotgun microphone, please refer to the following note:

“Easily accessible on the rear face of the microphone are the power, the level controls and a selectable high-pass filter at 80 Hz. The filter will prevent low-end noise such as air conditioners and traffic from being recorded. Furthermore, the -10 dB (or pad) is suitable when recording loud sound sources such as live music, motorsports, or interviews, where the subject is very close to the camera. There is a +20 dB level boost designed for use with DSLR cameras, so the user can reduce the camera’s preamp level, effectively reducing the amount of noise generated by the camera’s audio circuitry.”

Editing:

The recording was imported into Final Cut Pro X and split into three segments. Trim tool was used to remove unwanted clips. Title, transition, and lower third were added to each segment. Each final video was exported as Master File for Apple Devices with the highest resolution (1920×1080) as .m4v format. Apple Devices format is suitable for web upload or longer videos as it reduces the file size while maintain decent audio video quality.

Things can be improved:

The video quality can be improved by setting up two cameras with one focusing on the slides and the other focusing on the presenter. However, muticam editing will be involved in the post production phase thus more time is required for editing. It depends on user’s recording need, if a simple recording and editing is what they need, you may refer to this case’s set-up, however, if both presenter and the information on their slides are important to be recorded with better quality, then using muticam to record can be considered.
