double video editing?

[kr236rk]

Hi,

i have a short video that i want to bring out certain details from -

gone as far as duplicating the captured footage and positioning it above the original footage 'video 1', with copy footage now on 'vdeo 2' line above it.

now for the tricky bit

is it possible to work on video 2, cropping into details then, when finished, slotting these into Video 1, so that the continuity of the original video is not interrupted please?

this is important because the video has a synched soundtrack so i want to keep the action in line with it at all times, whatever i do to the visuals

it's video of a guitar player playing, and i want to zoom into the instrument here and there, without breaking the consistency of the music

there seem to be two possiblilities: either a) carefully deleting sections of the original footage and slotting in the details from the copy footage -

or b) keeping both time lines intact but 'toggling' from one to the other when required.

I don't think b) is going to work if i also want to add transitions / 'fades' though, that will require keeping all the footage on one video time line only?

suggestions appreciated!

thanks

I don't think you need a second image if all you are doing is zooming in, panning around, and then zooming back out again. Just use keyframes at the critical points and control with the position and scale properties. If you don't know how to do that, hollar and we will find some more help or tutorials.

Thanks Bobby,

I will have a go on a trial piece of dv and hollar if i get in a fix! [lol]

sounds like what i want is achievable anyway, which is great news

If you are wanting to edit between the tracks with cross dissolves this tutorial explains the multi track editing: The Learning Series, Multi track transitions part 2. Scroll down the page:

That's the kind of stuff a lot of us do all the time Ric, and the tutorial that Cheryl points out explains it all. If you have questions you know where to turn

I think the idea of having a duplicate on track 2 will be of benefit in this particular case. It will be easier to just zoom in on the whole second track and then transition between track 1 and 2 when you want a zoomed in shot. Should work out very well but you will need be fairly good at keyframing, we have plenty of tutorials and articles for that as well

Thanks Chuck and Cheryl,

I could not open that tutorial btw

Why don't i just select the frames i want to zoom in on, crop out what i don't want, select 'zoom' to fill the frame, and proceed accordingly? That way i am not actually breaking up the time-line at all, just enlarging sections of it every now and then. This will actually help with the dissolves because the cropped sections will mark exactly where i wanted the dissolves to be?

That still means i can keep video line 2 up the top as back-up just in case!

That will work too Ric.

That will work too Ric.

Thanks Chuck,

i split the line into half-a-dozen segments and experimented: one thing i noticed that the smaller you zoom a detail the greater the pixelation on zooming it, but i don't think there's any way round this - adding a sharp filter [@ 100] may have just slightly improved it?

one serious no-no was a segment i messed up in and got it back to a comfortable crop, then noticed to my dismay that the crop started undoing itself half way into the segment, like if i cropped left 35, it starts going 34-33-32-31, etc all the way back down again. can't stop this, i must have hit the wrong button somewhere? can i freeze the crop at set parameters please?

all the other segments have remained where i set-zoomed them ok

cleared the second (duplicate) video line in the end cos it was getting confusing.

thanks again

This sounds like it might be a 'rogue' or 'orphan' keyframe on the timeline. In the effects control panel click on the direction toggles for the keyframe. The CTI will jump to the next keyframe along each time you click. You may find a keyframe that has been left behind from previous edits. If there is one then, like as not, that will be the cause of the problem.

Thanks John - will update: it was the first segment i cropped and the crop didn't appear to be working, so i started messing around and have probably confused the software. All the other segments are working excellently. I suppose I could also 'clear' the rogue segment of its crop filter and start from scratch?

You might want to start giving the two track approach a try, it will be much easier in the long run I think. All you have to do is keyframe the Opacity between the clips, add a cut and a transition. But in the long run I guess it might not be that much different, just seems more natural because that's how I would do it.

The pixelation can't be helped, you can only zoom so close before it causes problems unless the video is very high definition. And even then you would see pixelation at some point

Thanks Chuck,

Will update - apart from that one segment this experiment has gone very well

Thanks John, you were right! Can't remember what i did but when i clicked the arrows the cursor bounced about 3 times within the offending frame, and several of those bounces corresponded with the eccentric crop parameters. Eventually i cleared the whole filter and re-set it. This time it stuck So that's great, this part of the project is sorted.

Now i guess i ought to load a rough piece of audio-video to PE3 and experiment with unlinking the audio (or copying it?) and adding sounds to it in a multitrack software, so that i can neatly plonk it back on the timeline, still in synch with the video?

thanks again

Glad that solved the problem for you, Ric.

[kr236rk]

many thanks - am going to return to the dual video edit at some stage due to the limitations imposed by cropping. Maybe i need two cams running, one wide, one zoomed, then parallel the video time lines and cut back and forth between them for better detail shots?
