Slow Motion with no pitch shift

[UncleBruce]

I am working on creating some language training videos. Most native speakers speak way too fast for learners to keep up with, so what I want to do is create scenes with sub-titles that run at slower speeds - e.g. 50%, 25%, etc.

Initially, I'm working on showing the scenes under program control (this lets me do things with the subtitles that a DVD can't do). The programming tools I'm using run the output thru Windows Media Player which is able to slow the video down by up to 50% with no pitch shift (this is important), but no slower (or speed it up to 2X)
(Oddly, it can only do this with .WMV files - I don't know why).

To fit into this framework, I want to take my source video and create a modified video that runs at 50% normal. That way, within WMP, I can speed it up to normal or slow it down to 25% - probably all the range I need. It is critical that there be no pitch shift.

I don't have any of the high end NLEs - I do most of my editing in Womble MPEG Video Wizard. But I am a student, and have access to the Adobe line of products at student rates - so a purchase there is not out of the question.

1) can I do this which the Adobe products? If so, which one (ones) will I need?

2) are there any other (lower cost, more specialized) tools that would let me do the same thing?

TIA

I now have a partial answer to my question - I hae a copy of Pinnacle Studio 12, and it seems to do the job I want.

I tried a couple of shareware products. They would change the video rate, but shifted the pitch. The audio transform that Pinnacle does in not great, but it works.

Audio software like Sony's Sound Forge allow for speed tweaking while compensating for pitch change.

Yes - I have SoundForge, and it does a much better job than Pinnacle on the Audio part - it gives many options to reduce distortion in the final audio. My only reservation about going that route is the hassle of doing the video changes in one tool, the audio in another and then getting them back in sync.
