Hi, LeigoAndre9999!

I think what you've experienced here is the default for when videos are sped up beyond 2- or 3-times normal speed, or even 4-times normal, probably because it's assumed with the sound getting so "garbled" by the speed-up process, it's no longer listenable. That's my theory, for what it's worth. I've used speed-up effect before, for comic purposes. I've usually opted to mute the audio. I have a clip of myself packing a tent at the end of a camping weekend, sped up it reminded me a bit of those old Benny Hill Show scenes where he was being chased by all those girls(closing credit sequence) with "Yakety-Axe" playing over the top of the scene! That's where I got my inspiration for my tent-packing video, I can tell you it got the desired laughs! Perhaps that's what you're after - speeding up a video for comic effect, along with the sound... I wonder if Wave Editor may be able to give you the appropriate sound speed-up, then you could import that back to PD14 and use it to replace the muted audio in the sped-up video clip. Just a thought.

Cheers!

Neil

You can speed up the video to 2X and keep the audio.
Produce your media clip at 2X speed, then take that new file (which still has the audio) place it in a timeline and speed it up again up to 2X, keeping the audio. Do this until you get the speed with audio you desire.

EDIT: Of course your speed may be LESS than 2X, I wanted to be clear on that, it was just an example, and is the upper limit of the module/effect keeping audio. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

Hello, LeigoAndre9999!

It may be a bit labour-intensive but Try Barry The Crab's method and see how it goes, keeping my menthod(also somewhat labour-intensive) as an alternative. Let us knowe your results, okay?

Cheers!

Neil.

It is NOT labor intensive in any way shape or form. A child can do it. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

Barry, what I meant by "labour-intensive" is the amount of work needed, and I made the comment about my own method too, in case you missed it. Your suggestion was to take the clip and double its speed, take the new clip and double it again, 4X original speed. If taken again and doubled, brings it to 8X original speed, along with resultant audio, that should be adequate, and avoid too much rendering.

My method may need a bit of calculation as to what pitch to set the audio, as it involves splitting the audio and video, then processing separately. The video could then be set directly to be sped up to 8X normal, but the audio would then need to be processed in Wave Editor or(if available) Audio Director to bring it to the same pitch(and length). That's what I meant by "labour-intensive".

Cheers!

Neil.

This is ridiculous and highly agitating, the method I am stating is fast and simple, period. I wouldn't even consider your way of accomplishing the OP's goal. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

Both methods have validity as is the way with editing.

There was no need for the post ( http://forum.cyberlink.com/forum/posts/list/48880.page#256426 ) made by Neil.F.1955, adding the comment "... bit labour-intensive" served only to cause upset, compounded by a lack of apology afterwards. You need to just say "sorry", Neil.F.1955.

Hate to throw a spanner in the works...

I just tested what LeigoAndre9999 did and - here - there doesn't seem to be any need to use either of the procedures described above.

First I inserted a pre-produced - 01:18:29 - clip shot from my web cam - applied a speed multiplier of 6.0000 & produced. The audio played throughout the produced file, in preview & media player.

Next I tested a 04:40:00 clip to see whether duration might have an effect. After applying the same 6.000 speed multiplier, the audio was present throughout, in preview & media player.

2/2 ain't bad.

Please note, this post is not attempting to denigrate either of the procedures outlined above.

Cheers - Tony

I do not need an apology, I simply need Neil to think while at the keyboard, stop making assumptions, and perhaps try or test methods before commentary. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)

My workflow was really offered as a workaround as the OP seemed to be having an issue. I figure it's best to get it done and worry about potential bugs later. Edit first, debug later.

EDIT: My testing showed no issues in my module, the sped up audio was present throughout all clips tested.

EDIT2: Niether Neil nor I actually addressed the potential issue with the OP's audio vanishing in the sped up clip, only offered methods to keep going forward. HP Envy Phoenix/4thGen i7-4770(4@3.4GHz~turbo>3.9)
