I took a few stills and some video of the commemorative Lancaster bomber flyover near to where I live yesterday. I was using my point and shoot Sony DHC-HX20V which is really difficult in bright conditions (no viewfinder) so the video was unsteady. I managed to rescue some clips to make a short video and stuck a few scrolling titles on the bottom. Nothing fancy at all and then uploaded the result to YouTube and accepted the video stabilisation that was offered. It improved the footage but had an effect on my titles that was unexpected (about 2 minutes in).

I've had PD for quite a while now but still only scratching the surface. Should I be trying to stabilise footage during editing?

I bet it was fantastic seeing it fly so close and so low.

For the most part video stabilization is just a way of making a video look less shaky. For instance, video taken from a moving bus, train or car. It works by simply zooming in slightly. It will not center an objsct. Keep that in mind.

Also, do all the stabilization BEFORE you do anything like adding titles. It looks like you may have added the titles while you were cutting/editing the video. .

Hmm.. Just looked at the help file re "Stabilization" and to be honest it never occurred to me I could do it in PD . I produced the wmv with titles and it was then stabilised by YouTube. Ah well another day and another lesson learned.

p.s. Yes it was a wonderful sight to see. Majestic would be a good description I think. The plane just seemed to hang in the air more like a glider at times. Living just a couple of miles away meant I knew where to get a good view

Hi Longedge -

I've had YouTube report videos as shaky when I absolutely knew they weren't. They were comprised of screen captures and stills! This occurred regularly when I used conversion software called VidCoder, which I've since stopped using.

Once I decided to click "Yes" to see what it came up with. Haha - it made it shaky! I guess the bottom line of that is - Don't necessarily trust YT's shaky video detection or processing.

Probably, if you hadn't used scrolling titles, the effect wouldn't have been so noticeable. Scrolling titles in PD have jerky motion anyway!

Cheers - Tony

Hi Longedge,

I've learnt to ignore YouTube's suggestions to improve my videos. PowerDirector could do a bit of a job there but I think that particular video of yours is as good as anybody else's footage taken without a tripod. I'd probably myself prefer the original resolution to sacrifycing it in the image stabilization process. The story and the uniqueness of the video are more important than the technical merits, in my humble opinion...

Hi Bolda & Tony

Yes I think you are both correct. As I said - another lesson learned, I'll be a wise man by the time I'm about 150 yrs old

Longedge,
Thank you for this post and the story of what Youtube does to your video.

I have seen that suggestion by Youtube many times and have always said no.

Like the Tony said, I knew my videos were not shaky. Whatever Youtube's detection method is, it does not work.

You can apply stabilization during editing in PD, it will not affect the other elements of your timeline. AFTER producing a video, it will affect titles, time-codes, anything like that. I might add that applying stabilization will stress your computer, so I often will stabilize, produce, THEN edit the new file.

I have seen videos on YouTube do that, but never knew why. Very curious. __________________________________

Speaking of stabilization, the last I did in PD11 I think was an improvement when it ticked the option Fix rotational camera shake.
Anyone ever bercebeu this too.
