Slow Motion

[zafgev]

Hi,

Using Videostudio Pro X5. Captured video using GoPro at 240fps. Video imports fine. I want to edit the video in slow motion. I'm using the "speed/time lapse" option - I set the speed at "25%". However the outcome is that the video is choppy as if it's throwing away frames. At this setting I should be getting decent smooth frame rates but this is not the case. I'm looking to end up with at least 25-30 fps.

Any ideas or alternative ways of editing to create a slow motion clip.

Thanks

Try stretching the clip on the Timeline. Press and hold the shift key and click on to the end of the clip. Pull out the clip to give the required "slow motion" effect. This process retains all the clip information.

Would be interested to know if this creates the effect you require.

Have you tried rendering the video to see if the choppiness is in the rendered video? If the rendered video is smooth, then the choppiness you see is a result of VideoStudio trying to make sense of your video on the fly. Try creating a Smart Proxy file to see if that lets you play the video smoothly. Even with a fairly powerful computer, I find that anything unusual can look terrible in the edit window... lots of choppiness and lost frames. Creating SmartProxy files makes everything as smooth as glass during editing. It can take time if you have big files, however.

Hope that helps!

Thanks guys for your suggestions however none of these have worked out.

Interestingly it seems VideoStudio has an issue editing files with high frame rates. Found this in the online-help - "The Corel VideoStudio Pro Timeline allows 30P (30 frames per second) editing by default. To prevent video clips with high frame rates from being truncated, it is recommended that you choose Enable 60P/50P editing from the Settings menu." Problem is my clip is recorded at 240fps. So I set this feature and I can see that it addresses some of the skipped frames but still is not smooth at for example 30fps.

BTW the free GoPro app - CineFormStudio (pity though it has limited editing capabilities) - renders this perfectly so I know it can be done. So come on Corel - how do I achieve this in VideoStudio?

no point in pleading to Corel on these forums - this is a USER to USER forum administrated and answered by users - it is not an official contact for Corel customer support. if you wish to contact Corel direct you can do so here:-

If the free Gopro app renders the video to a sensible frame rate say 25/30 or 50/60 can you not do that first - then you will be able to edit the output in VideoStudio.

alternatively have you tried putting your clip in the VS timeline then going to "Share >> Create video file" and then choosing a format which VideoStudio can edit - then put that video back into the timeline for detailed editing.

If you are recording at 240 fps VideoStudio will play back at 50-60 fps? Is this correct and if so do you want to slow it down even further?

If as Brian says VS slows it down to say 50-60 fps then any further slowing down will start to show individual frames and flicker will occur.

Thanks Brian - I did not really think Corel would respond. Maybe they use text mining software to gauge how peeved I am

Terfyn - The idea with recording at 240fps is to capture in ultra slow motion action sequences in smooth detail. Effectively you then stretch this out so that the final product plays at 30fps - ultra slow and smooth with no choppiness. So a initial clip of say 5 seconds @240fps, once stretched to 30fps will play for say 1 minute. Recording at 50/60fps will not capture the action detail which 240fps does.

Have a look at this for example - http://www.youtube.com/watch?v=LwtI5Eiomik - the clip is recorded at 240fps. At 10 seconds+ the clip is rendered at 30fps but "time stretched" with no loss of frames. VideoStudio allows you to time stretch at set the speed at for example 10% BUT VideoStudio loses frames and the video ends up being choppy. I've tested a trial version of Pinnacle Studio 16 last night which provides similar capabilities to adjust the speed and it renders the clip perfectly. So guess I chose the wrong product.

I'm surprised that a new gen video editing software does not yet cater for cameras capable of capturing 120+ fps for action sequences. $90 wasted.

Thanks for the help and advise guys.

Thank you for your reply. I wish you well using Pinnacle, I moved from Pinnacle to VideoStudio because 15 was problematic. Pinnacle 16 being, in all but name, Avid Studio 2, may be based on a more robust framework.

I tried a 25% speed reduction on some of my video clips. Clearly, as the time for each frame had been lengthened, there was flickering in the movement but no frames were lost. I believe that if you go the other way and speed up the video clip, VideoStudio will drop frames in order to reach the end of the clip faster.

I started with Pinnacle Studio 5 and worked my way through to 15. 15 locked up on me and I had to take my computer to the Dealer for it to be fixed. He recommended transferring to VideoStudio as, in his and his customers experience it gave less trouble. In my experience he was right to recommend VS.

Here is a thought for Christmas.
Now Corel own both Pinnacle and VideoStudio, will Pinnacle 17 and VideoStudio Pro X6 be the same programme?
