Speeding up the video speed without effecting audio pitch

What would be just awesome,.. if you could speed up the video and the pitch of the audio wouldn't change.
Just like in the VLC player,.. you can make the clip go faster,.. the sound (voice) is of course faster too,... but the pitch of the audio does not change.
This is great for watching tutorial videos,.. most of the times they are too boring to watch at 100% speed.
If Camtasia Studio would offer that we could speed up what we have recorded (just like it is now) only without it effecting audio pitch,... well that would just be a phenomenal feature and you would have a much better product.

best,
Met

Hi Met,
Thanks for taking the time to post this great feedback. I took the liberty of tagging this with additional products, including Screencast.com. Are you thinking that the viewer would have control over the speed, or as the content creator, you would set the speed for your viewers.

I'm sure a case could be made for having both, but I was curious to see how you would use this capability.

Thanks again,
Mike Curtis

Hi Mike,

Sorry for my late reply - this post sort of got under my radar :)
Anyway.... Let me answer your questions:
no I'm not talking about control over the speed of playing the videos on the viewers end.
Like I said as far as "on the viewers end" goes,... people use different players (whatever they like,... also depending on the operating system) to play back their video tutorials and other video content created by your products.

What I'm talking about is the control over the speed on the content creating side. In Camtasia Studio,... you can already control the speed of the video.
You can speed it up or slow it down and then export it. However if you change the speed of the recording the pitch on the soundtrack (voice over and/or background music) also changes. On this point you can develop a new and phenomenal feature - the possibility of speeding up the video without the pitch shift for the soundtrack.

What do you think?
I'm not sure I did a good job explaining this. If anything else is not clear, don't hesitate to ask... and I promise, this time I'll keep an eye out for your reply.

Windows Media Player allows for playback of videos at increased (or decreased) speed, without changing pitch of voices. Following up on the thread here, is there a way to RECORD videos at increased speed without altering pitch? Thanks

So basically when you speed it up you only want it to effect the tempo not pitch?

We have lots of students on our campus that watch Introduction to Accounting videos which support variable speed playback. Nearly all of them use this to watch the videos at double speed. I frequently make use of the 2x function for podcasts in iOS. Having that flexibility on the client side would be awesome. Since that is a function of the player and not the media produced by Camtasia, it would be nice to have some outputs on the production side for 1.7x or 2x speed videos.

Thanks for the discussion. This seems like a really interesting problem to solve. On one hand, you might have a controller playing the video where the viewer can have a lot of personal control. But, there are a number of likely cases where the content creator might want to (quickly and effortlessly) create "high-speed" versions of the video to make available.

We like a challenge though, and this is a great topic for our product teams to talk about.

On a personal note, I often crave a 1.8x speed or there about. For example, if I'm watching a recorded webinar.

Thanks, and please keep your feedback, examples, and ideas coming!
Sincerely,
Mike Curtis

Hi Mike,

Please let's drop the discussion about playing the video.
The whole point of this thread that I started was on the production side.
Also we are not talking about 2x speeds but only a slight increase,... lets say to 115%.
This would make a huge difference in creating just enough tension to keep the viewer more alert and open to information.

I will try to take the time to actually record a sample of what I am talking about.

I work with a number of audio tools that include this capability...within the edit environment, so it is a mature technology. Right now I am trying to edit a talking head segment where the speaker is going very very slow. If I could speed him 10-15% even, without raising the pitch...it would be perfect.

I have good news! This feature is implemented in Camtasia for Mac 2.1 which released April 24. Clip Speed is one of the new features in this release, and it speeds up or slows down both video and audio without changing the pitch. Simply drag and drop it onto a clip on the timeline, and you can adjust the speed. You can learn more about the release here: http://www.techsmith.com/camtasia-mac...

While Camtasia Studio does have clip speed, it does not have the ability to not change the pitch for sped up audio. This is under consideration for a future release of Camtasia Studio.

Best Regards,
Shane Lovellette

Hm. Clearly this must be easier to implement on the Mac then it is on the PC, because you would have done so for your larger installed base of customers....right?
However, to read that it is not on your development horizon - but only a "consideration" - at least as of two years ago, is a cause for concern. What's the status now? I know my coworkers at Intel would love to have this capability on the PC.

George, I echo your frustration, although I must admit I ended up buying a license for the Mac version (merely to get the capacity to keep the original pitch in a speeded up clip).  This was only possible because a colleague had just replaced his old Mac so I was able to use it.  NOT AN OPTIMUM SOLUTION (at least for me...)

@CAMTASIA @TECHSMITH - What's the status of this feature for PC? We need the ability to increase clip speed (when creating content) without changing the audio pitch. SIX YEARS AGO it was implemented for Mac's, why not for PC???? Please make this possible!

What I would do is change the clip speed in imovie, then detach the audio and load it into say garage band to mess around with the pitch. then import it back.

There are probably 20 ways to accomplish this, but as you suggest above it would be a many step workflow. The technology for maintaining pitch with changes in speed are now so basic - even Apple's free Garage Band include this. Techsmith's clearly does not see a need or they cannot envision how to market such a feature. Those here would need to make the case.

In our world, we have many step procedures that do not need to be shown in real time. The ability to speed these would be a big help.

While camtasia for mac does have an "adjust speed of clip", I'm running into issues while using it.

First: There is no "ripple adjust". I cannot say "Make this clip faster, and then move everything after it up on the timeline". I cannot say "Make this clip slower, and move everything after it down later on the timeline".

Second: There is no way to adjust any other track to compensate. Just looking at a typical recording, there will be a video track and two audio tracks -- yet only one of those audio tracks can be adjusted with the video, and only if you have not separated them into different tracks. There is no "adjust the speed of all of these tracks at the same time".

Third: When previewing at high speed -- if I set the clip to 300% speed, and review it, when I find the place I'm interested in doing something -- if I try to set the clip to 100%, to fine-tune what I am doing, then the playhead position in timeunits does not change, but the section of film that I am looking at is now very different. I cannot lock the playhead to the frame, and adjust the time setting, the playhead is always locked to the time offset from zero.

Fourth: While one potential work-around is to make a split, and adjust clip speeds, this has problems in that:
1: Lacking ripple adjustments for speed, I cannot select an entire track of mixed speed recordings, and set them all to 100%.
2: Lacking any ability to adjust multiple tracks' speed together, I cannot do this if there are multiple tracks of adjusted speed,
3: Lacking any ability to say "This section really does need to be locked at speed X for exporting", there is no way to both make sure everything is reset to normal, EXCEPT for what actually does need to be altered.

EDIT: 4: This litters my track with clips. And there is no way to unsplit the splits; stitching is not acceptable because it does not behave the same and looks distracting.

===

I cannot control the speed of multiple tracks together.
I cannot ripple-adjust all the right sides of all the tracks to account for speed changes -- this is useful for "Fit this piece into that space", but not for "This section of the whole thing needs to be faster because it's boring".
Attempting to use this for highspeed preview during editing wants a different set of features than using it for it's intended purpose -- adjusting the speed of a clip in export

ok it has been TWO YEARS & no ability to speed up videos & normalize pitch to match for windows users?

LOOK, if you don't understand the VALUE, let me help:
#1 - NOBODY HAS TiME for videos to playback at normal speed now.
#2 - YOUTUBE has a double speed option for almost a years now, FiNALLY,
proving this to be true.
#3 - ViDEOS that we can speed up & keep the speaking voice pitch normal mean:
****SMALLER ViDEO FiLES*****************
************FASTER UPLOAD SPEED*********
*****LESS HARD DRiVE SPACE******
*****MORE CONTENT IN LESS TiME
CONSUMED BY THE END USER*******

ALMOST EVERY ViDEO ON THE MARKET
CAN BE iMPROVED BY SIMPLY SPEEDiNG
UP PLAYBACK AUTOMATiCALLY AT __LEAST 15%__
IF NOT 50-100%.
================================
PLEASE ADViSE ON WHY NOT & WHEN WE CAN GET THIS FEATURE
INTO TECHSMiTH SNAGiT & CAMTASiA STUDiOS,
BECAUSE I CAN PROMiSE YOU, YOUR COMPETiTiON iS
ALREADY ON THiS, OR WiLL BE SOON.

thanks,

Has this been implemented for Camtasia Studio yet? I see above that it has for the Mac version.

When you are editing a clip with audio on the timeline, and change the clip speed, we really do need the option to adjust clip speed without affecting the pitch. It is not a useable feature when used with any audio clips unless you want your voiceover to sound like a chipmunk or a 500 pound gorilla.

I understand that I can alter the clip speed in another 3rd party program, but I really shouldn't have to. This should be a checkbox within Camtasia properties, or something within the preferences where you can enable or disable pitch change with clip speed adjustment.

Please add this feature!

Venture capital applications often require a 60 second introduction video to accompany the application. As hard as I try, I never can get the actual recording time to be exactly 60 seconds. Shorter is ok, but I typically run 65-70 seconds after clipping front and back. And we're never sure if they trash any application with a video longer than prescribed as a way of winnowing down the application pile. Would be perfect if I could adjust clip rate to 60 seconds without sounding like tweetie bird.  Also, as a university professor, I create video tutorials for my class. By policy, these need to be no longer than 60 minutes in length, and of course I always run over a couple of seconds. If I run over too much, I have to chop out something. But if I am just some few seconds over, it would be great to be able to compress the clip rate without, again, sounding like Tweetie. Audacity, the audio editor, has this feature, so sometimes I edit the audio in Audacity, add the shortened version back in to Camtasia, and then just adjust the clip rate of the video to match....but that doesn't always result in a perfect lip sync.  Please add this feature.

you can do what you want by applying clip speed adjustments in Camtasia and then applying pitch adjustments using free Audacity ...

I too am distressed this feature has not been added to Camtasia for PC.  Due to many edits to videos being improved for many years, I cannot use Audacity for this.  I need it in Camtasia.  Since the Audacity code is open source, one would think it could be added to Camtasia.  Can some one from Techsmith speak to whether or not it is being planned for any release?

Come on Techsmith! What a f*ckin joke! You guys should be ashamed of yourself for not releasing this feature. Time to use another screen capture software (plenty to choose from). Get your act together.
