AudioI rely on Sennheiser G3 for recording the speaker. Batteries (2xAA) can be swapped during the breaks for continuous recording.
Sony PCM-M10 recorder. Batteries (2xAA) can be swapped during the breaks for continuous recording. The recorder has space for more than 10 hours of recording, so the daily backup is desired. I record in PCM16/48kHz. The built-in 4GB flash is sufficient for 5h 45min of recording so daily backup is required.
Desktop/Slides RecordingMy tried and true solution is a hardware recorder with HDMI pass-through. External power brick is used, so no batteries to worry about.
AverMedia C285 is probably obsolete by now but it certainly does the job - it supports resolution up to 1920x1080 at 30fps.
The recorded stream is stored on the internal 2.5" SATA drive - I have a set of three such 128GB SSDs. Each can store more than 13 hours of 1080p 30fps video/audio stream in MP4 container.
Speaker/Audience RecordingUse GH5 with 12-35 2.8 zoom lens to record speaker and audience. 4K recording recommended so that a no loss zoom-in on the speaker face can be done in post. A single battery will comfortably power the camera for about 2 hours. I have 4 batteries, so daily recharge of those will be required. Camera has 2 SD card slots. Usually I record 4K 30fps in MOV container at 100 Mbps rate. Two 128GB cards should suffice for 6 hours or live video recording. Daily backup will be required though.
Post ProcessingDuring post processing the following tasks are performed:
- clips are synchronized;
- dynamic compression for audio is performed;
- video exposure/color adjusted ;
- content is edited to maintain tempo into clips of reasonable length - less than 45min;
- content is rendered to desired resolution (720p? 1080p?) and bitrate - YouTube guidelines recommended;
- Opening/closing credits are added. Adding corporate branding is an option as well.
Storage Requirements SummaryFor a week-long events the following storage is required:
|Recorder||Built-in Storage||Storage for a week-long (30hours) event|
|Audio||4GB, 5 hours||20GB|
|Screen||120GB, 13 hours||300GB|
|Video||2x128GB flash, 6 hours||256GB*5 - about 1.4TB|
Seems to be totally manageable. If full time video can be avoided, those become totally trivial.
