This is "F"ing confusing

No worries. All G Rated here!

RE: HPX special recording functions-

About the "F" in the menu settings for Interval Recording Time (2F,4F,8F...30S...10M).
I get the S&M (insert joke here), but I'm guessing the "F" stands for "Factor(?)". I know it's not frames because the 2F seems about 2X faster on playback than normal (hence the factor guess). Is this correct?

However, it seems the "F" for One-Shot Recording Time menu settings does mean frames, right?

One more question-
If I am correct (8F Interval = approx 3fps), what is the advantage of using the frame rate hack vs Interval? Is it so you are not locked into 30/60i/p and Video Mode?

Thanks.
 
This is really confusing. Is this a joke... lol.

2F = 2 frames per sec capture ... playback speed depends on your recording options, aka 30fps playback/recording would be faster than 24 fps playback/recording. 30s = 1 frame captured every 30sec. 10m = 1 frame every 10 min.

Interval recording means the camera will take, for example, 2 frames per sec for as long as you are recording. One Shot means the camera will take 2 frames every time you hit the record button and then stop until you hit record again.

Interval recording would be for a continuous time lapse, one shot more for stop motion animation.
 
The F can't be frames on Interval.

If you record a moving object with Interval Recording Time set to 2F and then set to 16F, the 2F plays back slower than the 16F. If 16F meant 16 frames/sec as you say then it should play back slower than 2F.
 
I don't know because I have never shot with this camera or interval record, but it sounds like F means frame. Seeing as your scale goes from 2F to 4F to 8F onto 30S(econds) and 10M(inutes) to is gradually becoming a longer period of time between capturing. My guess would be 2F records 1 frame for every 2 frames of time, 4F records 1 frame for every 4 frames of time, 30S would record 1 frame every 30 seconds.

Basically the recording interval would be: 1 frame/interval of time.

Click to expand...

The interval = your setting. Meaning the camera captures a frame every 2 frames.... or one frame for every 16 frames passing in time. So if your shooting 24 fps with a 2F interval then you actually capture 12 frames per second. Playback at 24fps would give you the illusion of 2x speed. A 16F interval would give you 2 frames per second, and playing that back at 24fps would give you even more speed.

Remember frames is a time code measurement in this instance. 2frame in time is you interval.

edit: what keller said
 
You can only shoot VIDEO CAM and 60i/30p, so everthing is calculated from 30fps. I'm just guessing here, but looking at the progression, I would say

2F = 2/30 = 1/15 sec interval (essentially one frame on, one frame off)
4F = 4/30 = 2/15 sec int.
8F = 8/30 = 4/15 sec int.
16 = 16/30 = 8/15 sec int.
and the next interval is 1sec, and so on.

This would seem to fit with Colonel Panic's experience that 2F plays slower than 16F.

(Again just guessing here - need to experiment I suppose). Manul page 47, and page 106.
 
bottom line is if you want to just hit record and walk away the only amount you can record on interval is 1frame at a time. they you pick the "interval" you want that one frame to record at. i.e. every 2frame, 4frames, .... 1sec, 5sec, .... 10min. if you want to record longer than 1frame at a time you have to use one-shot, but then you have to manually hit record every time you want to record. not sure why they didn't just combine these and let you record, say, 5 seconds every minute, or 3frames every 2 minutes, etc. oh well
