I'd like to run this one though the deshaker plugin in virtualdub because there was no image stabiliser on the camera.

But before doing do I need to convert the file to something that virtualdub can read and process because my mov file does not seem to make virtualdub happy....

WHat would be the best steps ?

Convert the mod into h264 or whatever so that I can run deshaker or find the way to open the mov file into virtualdub and run deshaker from it 'as-is'.

Does deshaker work "better" with one video encoding compared to another one ?

Thanks for the help

Don't convert, use the latest ffmpeg input driver to import that mov into Virtualdub for DeShaker processing.

Get it here: https://code.google.com/p/ffinputdriver/downloads/list

***EDIT: here are the latest versions. http://forums.virtualdub.org/index.php?act=ST&f=7&t=20025&

You can also use the deshaker filter in ffmpeg if you do not need any other editing of the video. The ffqueue GUI for ffmpeg can help you to deshake

Or better yet.....Batch 2-pass stabilize a whole folder of MOVs with my script: https://forum.videohelp.com/threads/368117-Batch-stabilize-script-for-ffmpeg

Looks nice! Do you have any experience with the vidstab detect/transform filters getting better results than deshake filter?

[txl]

Hello and thanks for all the tips, I'm trying to edit the original mov file in virtualdub to extract 2-3 minutes and then i'll try the different methods and report the results.

[txl]

AH, first problem in virtualdub, it won't read the audio format AAC 128, what do i need to solve this ?

Thanks a lot again

[TorBru]

You need the ACM AAC codec in order to decode AAC in VirtualDub. I am not sure that it is possible to encode AAC with VirtualDub (at least not with this codec).

Thanks, i' going to be the 1 457 254th idiot to say this but why the **** didn't they come up with a unique set of format.......

[txl]

Ok, got the aac running, will keep the video in direct stream copy, encode the audio in mp3 192 whatever and then start again

Thanks, I'll report the results....

you can't use "direct stream copy" with deshaker

[racer-x]

And all you need is the latest version of ffmpeg input driver, nothing else. You don't need aac acm.

1) Use the latest version of Virtualdub (I'm using v 1.10.5).
2) Put the the ffmpeg plugin in the plugins32 folder.
3) Drag and drop your MOV into Virtualdub.

[txl]

ok, got my file in AVC1 and MP3 192....now on to the fun part

Starting ffqueue with the deshake filter on standard setting.

Then I'll start a virtualdub with the deshaker plugin and we'll see what happens.

Thanks for the tips guys...

[txl]

Ok, first try with ffqueue was a complete disaster

started with a 290megs file and finished with a 2.4gig unusable file....

Did a virtualdub deshake and deinterlace, saving now, it says it will be 28gigs....

What kind of compression settings should I use ?

Thanks for the help

[TorBru]

Please try copy the block below, open ffqueue, open preset manager and click Paste and a new preset will appear named "x264 with deinterlace and deshake". The preset uses standard settings for deshake and deinterlace filters (you might want to experiment with the settings). It uses quality setting (VBR / CRF) for video (you can lower or raise the quality by editing the preset under Video -> Quality and adjust the best / worst constant quality. The audio-stream is copied without modifications.

Hello,

First of all thanks a lot for the help, the preset was created and everything went well.

The interlace part works fine, but the deshake not really.

The camera is fixed on the front bumper of a race car so it can be vibrating quite a lot.

The camera has no stabilizer and yet with a gopro with a stabilizer the same fixing point gives out acceptable results.

Is there a way to improve the deshaking part ?

Or can I put this file into virtualdub and deshake it ?

Thanks a lot

Post a sample. Other than technical specs we have no idea what you're dealing with here -- except that it's not a GoPro.

We don't know if the shake is coming from the road, from engine vibration, from sensor jelly rolling. For all we know the image may be completely acceptable and you're looking for some kind of magical steadicam effect. Conversely, it may be so full of vibration that there are no clear frames at all.

Post a sample, please.

Is there a way to improve the deshaking part ?

Record with a higher frame rate, 120fps or at least 60fps.

[txl]

Hello

Here are samples...

Original file straight out of the camera only with the sound changed from aac to mp3

File that has been though ffqueue with the preset included in this thread

Thanks for the help maybe I can get you a ride in the car

[smrpix]

You're basically going to have to decide whether you want the sky shaky or the cars shaky.

[txl]

I'd rather have the sky shaky than the cars

It looks super nice, thanks a lot
