Record a TV Program To PC

Overview One of my customers occasionally asks me to record a TV program as her daughter is an actor and she would like to use the program clips for her portfolio.

Equipment (Rack#1 equipment and setup)

  • TV monitor (optional)
  • A/V switch box
  • Canopus ADVC300
  • PC - SPACE
  • Vegas software for capture
  • Telus optic box and remote

Solution Summary

Plug the Telus box into the network.  The output from the box goes into the switch box that in turn feeds to the Canopus and the firewire to Space.  Vegas records from the firewire.  The TV monitor will monitor the output from the Canopus.

How To

  1. Get the Telus Optic box
    1. Plug in the network cable into the box...should be able to plug directly into the little swithc box under the modem by FLAG
    2. Power it up the box
    3. keep in mind that the box requires 15 to 20 minutes or so to initialize before one can use it
  2. Connect composite video and L and R audio cable to the outputs on the back of the Telus box and the input #5 of  the switch box
  3. Turn on the Canopus ADVC300
  4. Turn on the TV monitor (optional)
  5. Open up Vegas on SPACE and capture using DV
  6.  May have to open up Canopus Picture Controller to get the canopus to switch to analogue

 

 

Transcode for 4K TV

Objective: To get the highest quality transcode possible specifically focused on ProRes film transfers.

Resources:

4K ProRes 422HQ

2K ProRes 422HQ

4K smartTV Samsung

Current Myffmpeg and ffmpeg

Results:

  • 422 does not seem to work with myffmpeg – error
  • If 16:9 is not specified, then the TV shows a 4:3 with black bars
  • 4K, 4096x2160, only works once on the TV and then the TV shows black screen
    • Turning TV off and on makes it work again…only once more
    • Audio works
  • H265 does not seem to work
  • What does work:
    • 16x9
    • H264
    • AAC
    • UHD 3840x2160
    • 2048x1536
    • MP4
  • AVI and MKV are supposed to work….but could not get one working maybe due to the combination of other items.

MyFFmpeg parameters:

These parameters seem to work fine with our 4K TV:

  • UHD H264 High 16x9 MP4
    • Should work fine for 4K ProRes files
  • 2K H264 High 16x9 MP4
    • Should work fine for 2K ProRes files
