Do Magix care?

@Stephen Crye – I am maintaining a list of links to the standalone installers in section 2b of this. The latest update is https://dl04.magix.net/2016/VEGASPro14/update/VEGAS_Pro_14.0.0.252_update_Retail_x64.exe.

John, just for clarification, doesn’t alot of computer video run at 30 or 60 fps to match the 60hz of electricity, or is refresh rate not the same as fps? I know with working with ATEM switchers, it is imperative that I have a computer or laptop that can match the 29.97 or 59.94 fps or my switcher will not recognize the signal.
Just want to make sure I am understanding this all clearly. Video does 29.97 & 59.94 fps, film is 23.98 and 24 fps, and pal is 25 or 50 fps. Not sure how computer video fits in there…

Thanks in advance.

Scott, You are correct that the refresh rate of computer displays is tied to the AC current frequency of 60Hz and the frame rate of televisions is also ties to this as well. That’s why countries that have a wall current of 60Hz use 30fps while countries with a wall current of 50Hz use 25 fps (exactly half). They use a timing circuit that is synced to the electrical currents frequency. The problem of 29.97 came about when color TV was introduced. The additional color information was having phase problems with the audio signal so they offset the video by 0.03 fps to move them out of phase and restore picture quality. We’ve been stuck with this solution ever since.

Computer video has adopted the analog standard simple because it was the standard. There was no technical reason to propagate it except for the fact that, at the time, all computer video came from analog sources which were 29.97fps. Now that everything is digital it seems silly but here we are, with an analog “ball & chain” around our ankles until someone declares a new standard.

Judging from the fact that the transition to HD was the perfect opportunity to do away with interlacing and they couldn’t even agree on that, I would guess that the standard will never change. The sad fact is that existing body of work is keeping us from moving forward.
