Slow motion video is the same as regular speed

Slow motion video is the same as regular speed
It looks like "slow motion" checkbox does not affect the speed of the video.

Here's the example:
http://www.webpagetest.org/video/compare...YT-r:1-c:0

Both videos are the same speed:
http://www.webpagetest.org/video/view.ph...N_1DYT.1.0
http://www.webpagetest.org/video/view.ph...T.1.0.slow

Might be related to video auto-generation (or am i wrong that it WPT is doing that?).

RE: Slow motion video is the same as regular speed
Hmm, looking into it now. The "slow motion" videos are just encoded at 2fps instead of 10fps and when I play back the pre-rendered script it is playing at the correct speed but the mp4 seems to be losing the slowdown.

It definitely used to work so I'm sure I broke something - hope to have it fixed soon Sad

No problem - it's quite useful and I create them at our Meet for SPEED sessions to help people understand what's going on. I'll keep an eye on it Wink

RE: Slow motion video is the same as regular speed
ok, fixed - thanks for pointing that out. I broke the directory parsing when I added an extra level of nesting to the ID's so they were both being written to the same location (single-test videos only). Whatever was created first is what would have been used for both so if you only created a single video of a test it would be fine.

I put some backward-compatibility code in place so any affected videos from the last 2 or so weeks will still work. Any newly created videos will not have the problem.

Thanks,

-Pat
