Hello ,
I make a TAS on Super Mario Bros and , for the time of the TAS ,1 frame = how many milliseconds or seconds? I suppose 1 frame = 1 millisecond but I am don't sure...
Thanks!
Hello Alex76FR
It depends on the system framerate, which is usually around 60. So a frame is 1000/60, or ~16.667 milliseconds long.
On NES, the exact framerate is around 60.0988 fps, so it's probably closer to 16.639 milliseconds per frame.

OK...
So how to calculate the time of the TAS?
If you know the frame count of a TAS, you can find it by using BBCode like [frames]12345@60.0988[/frames] on the forum. It'll show like this: 03:25.41
Alternatively, you can upload the movie to userfiles and it will show you the movie time.
Alternatively if you want to manually calculate the time of a TAS from a framecount, divide your frame count by the framerate and you'll have the length of your movie in seconds. E.g, 1234 frames / 60.0988 fps = a 20.533 seconds long movie.

<dwangoAC> This is a TAS (...). Not suitable for all audiences. May cause undesirable side-effects. May contain emulator abuse. Emulator may be abusive. This product contains glitches known to the state of California to cause egg defects.
<Masterjun> I'm just a guy arranging bits in a sequence which could potentially amuse other people looking at these bits
<adelikat> In Oregon Trail, I sacrificed my own family to save time. In Star trek, I killed helpless comrades in escape pods to save time. Here, I kill my allies to save time. I think I need help.

The emulator usually displays it somewhere and you don't need to make any calculation. The movie format can register the time too. But if you need it anyway, here is how you do:
seconds = frames/framerate
Be careful. If you use the European version of a game, the framerate can be lower. Example:
frames = 25400
system = SNES NTSC
Therefore:
seconds = 25400/60.0988138974405 = 422.637 secs = 7 mins and 2.637 secs
It seems like you don’t understand what a frame is. A video is made of images. A frame is each individual image that makes a video. Each one of those images is 1 frame. The framerate is how many images (frames) appear in a determined amount of time (usually 1 second). If the framerate is 60fps (frames per second), it means that there are 60 images in 1 second. Once you know the framerate, as has been said, it’s simple mathematics: frames ÷ framerate = time in seconds. 60 frames (images) at 60fps is 1 second. 30f at 60fps is 0.5 seconds. 60f at 30fps is 2 seconds.
My explanation sucks but maybe you understood something from it. Wikipedia has a page on this, which may be of help: http://en.wikipedia.org/wiki/Film_frame
