Speeding up a section of video.

Hi Again Folks:

Before I get to my PD questions, how do I get spell checking to work when I compose an original post for a thread of this forum?

Replies seem to have their spelling checked.

Anyway...

Like most powerful software, PowerDirector is a challenge to the uninitiated.

My current project is to fast forward at 10X speed to 1:17;22, then drop into normal speed for awhile.

It wasn't hard to find that the "Create Time Shift" was in the "Action Camera Center", but I still haven't found the "Tools" referred to in the following description on page 89 of the User's Guide.

Note: if your video clip is already on the timeline, you must select it and then click Tools > Action Camera Center to open it in the Action Camera Center.

But if I click on the video in the library window and select "Action Camera Center" from the menu popped up by the the plug-ins button it seems to work, kind of.

I hit the gear icon and select "Remove audio".

I hit the "Effect" tab.

Clicking on the "i" button next to the "Create a time shift" section of the action camera center displayed this, can't copy and paste, sorry about typos.

Move the timeline slider tot the point where you want to start editing the effect and then click the "Create time shift" button.

Drag the boundary to select the segment. Specify an expected duration or choose a playback speed for the selected segment.

The slider starts at zero, so I leave it there and hit "Create time shift". I set the slider to 1;17;22 and set the speed multiplier to 10.

Then I try to play it in the action camera center's preview.

It fasts forward just like I want, but it doesn't stop running in fast forward until 4:22. At that time it drops into normal speed but it seems to have no sound.

Why doesn't it drop out of fast forward at 1:17;22?

When I click "OK" to quit the action camera center and watch what I've done in the preview window, the video fast forwards far past where I want it to go to normal speed.

After that it has an inconsistent kind of slide show, then run fast to catch up quality, that suggests to me the two video tracks are competing with each other for CPU time.

The timeline section looks like this:



I had to shove track 2 to the right in order for the fast forwars to start at frame 0.

I kind of thought I'd just tell PD that I wanted 10X speed from 0 to 1:17;22 and everything would be golden.

What am I doing wrong?

Thanks
Larry

Hi Larryl

just off the top of my head I am not at my PC so I can't test this. But why don't you split the clip where you want the speeded up section to end and then just speed up the first section of the clip. Hopefully this will give you the result you are looking for.

Regards

Thanks Collie:

Look! The spell checker works when I'm replying.

I've been slammed with work but I'll check it out tomorrow.

Track 2 is the fast forward track.

I suspect I just need to snip the part I want to fast forward over out of the start of track 1, snip off unwanted stuff at the end of track 2, and slide track 1 so it follows track 2. I think, with help I've received from my two threads and stuff I've been reading I can do that.

Does this sound right? Is there an easier way? Is there a way to know track 1 is butted right up against track 2 with no gap or overlap?

I was working on that until 3:00 AM last night and my mind was going soft.

Many more questions to come.

Thanks for your assistance.

Hi, Larryl!

Just by way of explanation, Track 1 is the "master" video track(with accompanying audio track), Track 2 is a fixrd(permanent) overlay or Picture-in-Picture(PiP) track(again with accompanying audio track) There is an effects(FX) track between the two which applies effects on to Track one. Any subsequent PiP tracks need to be called in via Track Manager.

For your effect(speeding up) to work best, it might be an idea to isolate the portion you want to speed up, by splitting the video at the point where this effect should start, and split again at the point where the effect should end, highlight the area between the two splits and apply your desired effect.

Cheers!

Neil.

Thanks Again Collie, Neil and JL_JL:

First, a couple of very simple questions;

Is the term "clip" used to to describe the items I've pulled from the Media Room into the timeline for editing? Or is that a term to describe a piece of video that's been split from another piece.

Are there things people who know what they're doing do and don't do to Track 1, master, and Track 2, fixrd? At this time I'm not interested in fancy fades or wipes, so I guess I don't need to deal with the FX track.

On to the issues I'm struggling with.

I've tried a bunch of different approaches in a frustrating Saturday.

The video in my first editing project is of a session someone gave me showing how to strong players move about on the battlefields of a video game, World of Tanks.

It's me following this guy around as he gives commentary.

I'd like to shorten the video by fast forwarding through less interesting parts of the presentation and then play sections at normal speed. The idea is to give the viewer a context of where we are and how we got there.

It's been a frustrating day.

Splitting the video into sections I'd like to speed up and sections I want to run at normal speed sounds like a great idea. I'm not sure the tools I'm using recognize those splits.

From what I've read and seen, I believe I'm looking for the "Time Shift" effect, with ease in and out.

These features are accessed through the "Action Camera Center". Is there another way to get to them?

If I select a segment I've just split, the Action Camera Center text is grayed out and I can't access it. It seems on only be accessible when no part of the video is selected.

The Action Camera Center seems to have no respect for, or even notice, the split I've made in the video. It seems to create a new section of video consisting of the entire collection of segments without regard of the video segments, and plops it down at a split point in the timeline. That's not what I want.

Here are some screenshots I've made of my latest effort. Perhaps you can see what I'm doing wrong.

This is the first odd thing:



I don't think this has anything to do with my problems, but it's a bit annoying. It tells me the video is at 30 FPS but my preference is for 29.97 for some reason.

However...



It looks to me like my preferred frame rate is 30 FPS. Why am I getting the warning, and is it impacting the result of my editing?

Jeff's reply that follows looks like it resolves the following issues.

Here is the Action Camera Center menu I get when I have any segment selected:



So, splittng the video doesn't seem to have much effect.

I drop down to the Effect Room and back to the Media Room, and I can open the Action Camera Center.

Here I've identified the section of the video I want to fast forward:



And this is what the timeline looks like after I close the Action Camera Center:



The actions performed in the Action Camera Center seem to apply over the entire video, without regard to any splits, then plopped down, in this case, at the split.

This seems to work, but drops out of fast forward a second too late. I lose a word in my dialog. I've been very careful to tell the time shift to end at the exact frame that will end before the missing word.

I just noticed that while the frame to stop on is 1:17;22, the durration of the speed effect is 1:18;10. I don't know why there is a discrepancy, but perhaps I can make use of this to revert to normal speed at a better time. This might be easy for a speed effect that starts at frame 0, it might get complicated for latter sections of the video with speed effects.

When I look at the segment that has been modified in the preview screen, it starts ok, but after a couple of seconds the presentation turns into a slide show. It pauses for a second, then runs fast forward for a half a second, and repeats this past the point it should drop into normal speed. Eventually, perhaps after 10 seconds everything synchs up.

I produced the video and the result is fine, except for a 1 second delay that causes me to lose the first word after I drop out of fast forward.

I have several sections I want to fast forward through. It looks like I won't be able to check my work in the preview screen. If I have to take the time to produce the video each time I want to see how the edit looks, it's going to be a long process. Production takes about a second of real time for each second of video. After the Action Camera Center duplicated the video, the production took a long time. I know I won't have to product the duplicate video, but it still seems inconvenient.

My computer is reasonably capable. It's a high end ASUS G750, a two year old gaming laptop with 32 GB of memory. Is this not enough horsepower to preview a video as it's being produced?

I hope you experts can help me over these bumps.

Again, I appreciate the time you've taken to help me.

Thanks
Larry

THERE is that Tools menu item.

I was looking all over for that thing, I guess I didn't have a clip selected at the time.

This looks like the way to bring up the Action Camera Center when a clip is selected.

Running the time shift on a clip resolves almost every issue. Thanks.

One annoyance is the preview. It still stuttres. The final production looks great. The delay that was causing the first spoken word following the shift is gone because the time shift is limited to the select clip.

Now that I can be confident that the time slip will be constrained to the clip, I don't think I need to preview for this task.

I can imagine there are other times I'll want to preview. Any way to get better previews when using the time shift?


Thanks
Larry

Hi, Larry! A "clip" is a portion of the video you're editing. A lot of SD Card-based cameras now, store each sequence of video shot as separate "clips" on the card. So, if you've shot five separate sequences in, say, a 24-hour period, they will likely be stored in a folder on the SD card(in some cases the camera stores them in the "root" of the card rather than in separate folders for any given day) In one way or the other they'll be identified for easy assembling in order of when they were shot. In the case of folders, the folder will be labeled for the day on which the sequences, or "clips" were shot. So, yes, the term can be used to describe the piece of video dragged onto the timeline from the media library. The FX track is not for fades or wipes, they're transitions, which are slotted in between the "clips" to create an impressing segue from one clip to the next, particularly if the content of the first clip(a beach scene, perhaps) doesn't relate to the next(a scene in the snowfields, maybe). The purpose of the FX(effects) track is to create delay(sort-of like strobing), glassy appearance or whatever effect you may want to use. Go to the FX room to see what is available. The next below FX is PiP Objects, then there's particle effects. Just tried a couple of these, they cannot be superimposed over a clip as they cover the clip for the period they're on screen. There's no chroma-key provision, so the best use for these is as backgrounds for title sequences etc. PiP objects can be overlaid on your clip to give a decorative effect. But it's entirely up to you whether you use any or none of what I've just described.

Cheers!

Neil.

P.S. I realise I haven't addressed the speeding issue. I did a video some time back of myself, packing a tent after an Easter weekend camping trip, and for comic effect, I sped it up to 12X and put Boots Randolph's version of "Yakety-Sax" on the audio track. The Speed adjustment is in the "Power Tools" accessed just above the timeline and is fourth of five options, the other four otions are 2D to 3D, video in reverse(also good for comic effect), crop and zoom, and video rotation.(turns the video on its side, either side, or upside-down or possibly and degree in between. You could shoot a scene, turn it upside down and say you shot it in Australia ha-ha!

Preview of sped up video will always stutter with PD14 until approach is modified by CL. It is difficult to skip frames to simulate speedup effect with highly compressed encoding of common consumer camera source footage and maintain playback fluidity. You can reduce this effect by reducing your preview quality (icon just to the right of camera under the preview window) but yes that comes at the expense of visual clarity in just the preview.
