Is it just me or does film play back faster than live?

Is it just me?

I've always felt that film viewer files replayed the game footage too fast as compared to when I actually experienced it. I've always felt you had to slow down to about 0.8x on the film playback to get a better "feel" for how things went down.

On my new system I set up AH as a test to see how well it handles the full detail sliders and shadows (answer: great!) but when playing back some film I copied over from my other PC's setup it seems very fast. Not keystone cops, but definitely 1.5x or more (subjectively guessing).

P-39D 37mm tater rounds are very slow firing, but they were popping out rapid fire in the 3-4 round bursts I was firing on film. Almost looked like 20mm fire.

This was the new system:
Intel i7 960 running stock (3.2GHz I think?)
6GB 1600MHz DDR3 tripple-channel
Radeon 6970 2GB
OCZ Revo x2 100GB SSD as primary (also game/film installed here)

Running 1280x1024 (monitor max) with full details, maxed out everything except smooth shadows was off.


So is it just me? Surely it can't be. I've read a couple comments about folks making AH videos from film clips that suggest slowing it down to 0.8 or so as well.

Use your watch or other clock to time a minute or two of film.  Does it take one minute of time for one minute of film to pass?  If it does then the film is playing correctly.

A possible cause for the film to look like it is running faster is your adrenalin level is not elevated while watching the film.  Adrenalin makes your brain process information faster (over-clock) which makes the action slow down.  The phenomenon is know as Temporal Distortion and is the reason it seems like it takes 15 seconds after rotating the handles before the canopy separates from the aircraft and another 30 seconds before the seat catapult fires.  For those who thought they had all the time in world, it can take the rest of their lives before the parachute opens. 

So yes, it could be just you.

I had considered that relativity of time, hence why for the longest time I thought it was me.

However, most times when I'm doing something such as flying or fighting etc, I'm not stopping to start a recorder.

I may have to record FRAPS on film viewer files to break down the individual frames of bullets on that P-39D example, then break down the exact firing time "live" and compare the two. That should be a good indicator, right?

I'm also a bit miffed that some older films are all broken. I didn't have a fast enough system to really make decent AH videos before now, and now all my footage is useless!

Just did a simple test, started a sortie (offline with autofilm) and started timer right as I launched.  Ended flight at 1 minute (by my digital watch) and saved film.  Opened up film viewer, opened up film, it was one minute.  Played the video against my watch again, one minute.

I'm going to agree with the adrenalin theory.
LOOK EVERYBODY!  I GOT MY NAME IN LIGHTS!

Folks, play nice.

Did you check the playback speed in filmviewer to ensure you did not kick it up a little??  :salute
