Time lapse...

I will be using my camera next week on a shoot where I need to use the time lapse feature. I am doing a consumer reports type shoot with a new oven that claims it can cook a completely frozen turkey in 2 hours. I want to use my DVX100 for the time lapse part of it and I will be shooting the rest with my Betacam. What is the best interval setting to use for a 2 hour block of time?
 
Re: Time lapse...

thanks for posting a thread. I just did a search and found only what I originally posted about. I am not sure why the search feature on this site is like that. I have had problems in the past with other archived threads I was trying to find.

I don't know why you can't find the results that you are looking for, but just in case... Make sure you check the bottom of the search page after you type in "time lapse" or whatever you are searching for, and CHANGE the "number of days" for the search, otherwise it defaults to "7". You can also change the number of posts to show.

Good point! :D That probably explains a lot of users frustrations with that dang search page. I think I'll PM Jarred about changing that default.
 
Re: Time lapse...

I did a time lapse test today and it didnt turn out like I was hoping. I had REC time set to 1 second and the INTERVAL time set to 1 minute. I recorded some trees with leaves for about 30 minutes which amounted to 30 seconds of video. I had the camera locked down on a tripod but when I played the video back it was choppy. Choppy meaning it wasnt a smooth time lapse effect. Would I have to import that footage into my NLE then smooth it out to get that? Or should I change the REC time and the Interval time?

I have a shoot this week where I need to record a turkey being cooked. The cooking time is 2 hours. I wanted to shoot a time lapse of the cooking.
 
Re: Time lapse...

I think you need way more footage and maybe half a second less recording time then speed it up in your NLE.

Choppy can also be caused by your subject matter. If you are shooting objects that are moving around a lot then you will get chop.

Ok, so you cook for 2 hours and want to show this reduced to how long? Let's say you want it reduced to 30 seconds. Now, what's the framerate of your final output? 60? That means you will need:

(30seconds) * (60 frames/second) = 1800 frames of video

Next, calculate the interval for the total time of 2 hours but converted to seconds:

(2 hours) * (60minutes/1hr) * (60seconds/1hr) = 7200 seconds

Finally, divide the total time by the required frames:

(7200 seconds) / (1800 frames) = 4 seconds / frame

Therefore you will need to shoot one frame every 4 seconds. But, the DVX only supports shooting a minimum interval of 15 seconds. So what to do? Well, you could change the length of time you want the final time lapse. Or, you could record normally and switch tapes when the first is almost done. Then import both and reduce in post.

One good thing about filming the cooking is that each frame will change gradually and shouldn't look that choppy.
 
Re: Time lapse...

Thanks Hans....I will have another attempt to practice tonight before my shoot tomorrow. If anything I guess I could just do like you said and just record it normally then use the time remap tool in FCP to speed up the footage.
