I often use clip speed, and at times, more so recently as low as 20% to slow down 60fps high speed recordings. At times iv used upto 900% to speed up longer live sculpting sessions, why?

Thankyou?

Daniel,

Sorry it's not very clear. Clip speed is limited to a range of (50%-400%) if the clip has audio. This is because of processing issues involved with applying really low or high clip speeds to the audio.

You can get around this by splitting the audio and video (it's in the right-click context menu), then applying clip speed to the video separately. Video-only clips have a much broader range for clip speed, all the way down to 1% and up to several thousand (it fluctuates based on the length of the clip).

We figured that most people don't use clip speed on audio (since we don't yet support pitch correction), so having to split the audio out, while annoying, still supports most of the workflows our customers use.

Randy - this is a great tip! Thank you. It's too bad this tip isn't presented in an abbreviated form on the Clip Speed dialog pane. Instead the user, unaware of the reason for the 400% limit, is left with the impression that they can't speed it up any further.

Consider expanding the note on the pane:
Note:Audio will be impacted using Clip Speed. To increase speed of video beyond 400%, split and discard its audio.

Hi Randy.

I actualy keep the audio in when clip is slowed down to add to the effect. Im putting together some fishing casting videos that are recorded at 60fps, and am slowing down the casting for the viewer. Hearing the swoosh of the rod at slow speeds aids in the impact gicing the impression of power when viewed at very low speeds. Im guessing that this is not somthing that everyone will want to do, but I am using Camtasia as a Video editor for movies, not just for screen capture which I do alot of as well.

Having now know I can have the flexability of lower speeds without audio, I will spit the video from audio as its more improtant to me than the sound aspect of it.

Thanks for the infomation.

Hi Daniel,

Thanks for your feedback! Your use of Camtasia Studio sounds really interesting. Would you mind sharing a link to your fishing video when it is done? We like to hear and see how customers are using Camtasia Studio in unique ways.

Thanks,

Hi Shane.

The Fishing video that iv just completed is not a public video, but id be glad to send the link direct to you. I can produce a public video which shows the methods im currently using if that would help.

In a nut shell however its a good way to show your viewer somthing full speed, half speed, then half speed with extended frames at certain points to create a pause effect. The extended frame allows to me add arrows, now thankfully animatable, callouts and voice narration. After the break down of a certain task like a distance fishing cast, a pendulum cast for example, the full clip can be shown at full speed again. Its essencial that the zoom level and position remains consistant between these sliced clips.

The good thing with version 8 is the quick way in which I can now add transistions, This realy speeds things up for me.

In camtasia studio 8, i cant adjust the clip speed beyond 400%. And also after adjusting the clip speed, it is running frame by frame where as in camtasia studio 7 there is no problem in adjusting clip speed and also clip is running smoothly, if i increase the speed.

OK...now I get it. You have to split the audio out from the video, then delete the audio and then you can change the clip speed to 999%.

I'm still wondering why the record in time-lapse was removed in the first place. I was able to make way smaller size movies and still get the same effect. Now that I record in 1920X1080 I have huge video files that are 30 - 60 min long only to reduce them down to a shorter time period.

I really wish the record mode would come back.

I do like the fact that I can see how fast or slow the clip is within the timeline, but agree that it was handy to record in timelapse. I still would like to slow it right down with audio in place, maybe somthing that can be added in future updates.

I downloaded the trial specifically because I thought it still had the time lapse functionality. Is adding that feature back in on the roadmap for 2014?
