shaking mov

Hello,

I have converted some .mp4 files (form a samsung camcorder) to .mov using iMovie.

Now .mov videos are trembling/shaking when converted in any video file format using iMovie.

.mov video files are perfectly played by iMovie but When they are converted and played by Quicktime they are trembling again.

The situation is Mac and OS X independent, i've tried to play .mov files on another Mac with another OS X (10.8.2) the problem keep the same : videos are trembling.

Perhaps, some video specialists have an idea upon the problem i met.

Thanks for your answers.

can you elaborate this …

why manually conversion, not the intended iM import routine?

what camcorder (model)?

which converter tool?

what conversion settings?

there's some exotic effect, called field order swap, which happens when interlaced sources are converted incorrect.- could be avoided/repaired.-

Files were converted in .mov when my son drag all .mp4 files from the camcorder to iMovie. I don't realy know which kind of action(s) he did, but the result is : .mov files appeared on the iMac and no more .mp4 files on the camcorder.

The camcorder is a Samsung HMX-H200P.

When i try to convert shaking .mov files to .mp4 file format, i use iMovie Film import and iMovie film export (Cmd-E)

About settings, i've tried for 5 hours basics settings and numerous personalized settings but the resulting movie is always shaking.

according to my usual source

http://www.camcorderinfo.com/content/Samsung-HMX-H200-Camcorder-Review-37812.htm

your device is a normal AVCHD recorder, no mp4.

connect your device or insert the SDcard into a card reader and choose 'Import from Camera'.

.... manual conversions go wrong in 90% 😉

Sorry, i have'nt been clear enough :

From now .mp4 files present on the camcorder import correcty on iMovie.

The problem is with some files converted by my son a few weeks ago. These files are in .mov format (shaking) and we don't have the correct and original .mp4 files.

I just need to correct these files in mp4 format without this shaking problem.

The camcorder produces mp4 (H.264) files on its hard disk.

very difficult to give useful advice ...

without knowing what#s going on on your side of the pond 😉

for instance, your cam doesn't produce nor record mp4 ... but, whatever:

give the free tool

Jes Deinterlacer

a chance

open/import your shaking video and under Project select

Change field dominance ....

probably, it will correct the shakiness.

Also, the Samsung camera is not on the iMovie Supported Camera List. Might be best to convert using a third party tool like Voltaic or ClipWrap.

It's not the problem, it works great ! This camcorder procuces mp4 compatible with iMovie.

The Apple Database is not always up to date.

I have yet import mp4 from the samsung and export these files with iMovie : no problem.

If you read my previous post you'll see that my problem is with some files converted accidentally to iMovie in .mov and that are shaking.

I agree with you !

I've tried Jes Deinterlacer but it didn't correct anything. I've tried other options from this software with no success too.

Thanks for trying to help me 🙂

One more thing to try. Right-click on a clip in the Event and see if it offers to Optimize Media. If it does, click it. That should cure it.

I've yet tried this option, unfortunately, it gives nothing more.

Thanks.

… which could mean, your manually converted stuff got somehow deinterlaced - no interlace, no fields, no changing field domination - if this was causing the jitter .....

sorry, from remote, this is end of my road, maybe others have better suggestions. 😟

What a shame 😟. Thank you for your advices.

The Exact Camcorder model is Samsung HMX-H220SP and the manual says it can encode H.264 (on the first pages).
