Simultaneously play back multiple video files

Re: Simultaneously play back multiple video files

Dear Omar

I have used Wax 2.0 (www.debugmode.com) with success for vieweing three videos simultaneously. It has very good video mixing abilities but sometimes problematic with audios. Another software which I have used and worked well for me esp. with the audio part is Zwei-Stein 3.1 (http://www.thugsatbay.com). Both these are freeware. Now, I use the Wax for mixing videos, Zwei-Stein for mixing different audio parts, and then again Wax for mixing the resulting mixed video file and mixed audio file into one full file having both video and video. It has worked for me like this till now.

I found out that if you have the videos with 24 frame per second, then the audio part of the Wax 2.0 works well. You can use Factory Format (http://www.formatoz.com/) to change the frame/sec of the videos and then import them into Wax for editing.

Dear Omar,

Please refer to the following web site, if you prefer a programmingless tool.
http://www.dkh.co.jp/en/product/vide...reference.html

This software (commercial product) will simultaneously play AVI files side-by-side, and also overlayed(superimposed). You can export them to a new video file.
For further applications (for example, 2D anlysis, drawing annotation), please see a brochure on the web site.

Re: Simultaneously play back multiple video files

Dear Omar,

There is an open-source software named Mokka which is now able to play video files (see "Mokka 0.5 is available for free download" posted few days ago on Biomch-L). I never tried to read 4 videos at the same time, but it is possible in theory. You have all the tools to select the frame to read, select the speed of the playback and if necessary you can play on the delay of each video to synchronize them.

However, the current limitation is that you have to load first an acquisition file recorded by a motion capture system (Vicon, Motion Analysis, BTS bioengineering, Codamotion, etc.) and then you can import your video files if they are not detected automatically. If you don't have any of these acquisition files, we can imagine to develop a function in Mokka to import directly videos without the required acquisition file.

Regards,

Arnaud

With MotionTwin you could Playback as many video synced as you like. http://www.simi.com/en/markets/ortho...win/index.html
There is also a small version of it for just about 100 EUR

Re: Simultaneously play back multiple video files

Hello,

I am looking for software that will allow me to load and simultaneously play back multiple video files. I have found software that will allow me to play two files side-by-side . e.g.

http://www.kinovea.org/en/

However, I would like to be able view more than two (my current need is to view 4 at the same time).
Does anyone have any suggestions?

I know I could open multiple instances of a video player (which is what I'm currently doing) and I know another solution is to load the files into a powerpoint slide and set it to play back all videos together. However, I'd like to find a more fit-for-purpose and less clunky way of doing it.

Thanks

Omar

Omar:

Send me your e-mail address and I'll send you a copy of our shareware application that will play more than 20 .AVI streams in sync. The program also lets you perform some simple manipulations of the streams (scaling and rotation of individual streams) and make basic 2-D measurements.

Hi Omar,

You should definitely check out ELAN: http://www.lat-mpi.eu/tools/elan/

It is free for use in non-commercial s/w applications, great for synch'ing & annotating video and audio files, and easy to learn. We have used it successfully to synch and analyze 4 video clips (this was an ergonomics-related task analysis). You can also save your synch'ed files as a project for later use.

Hope this helps.

Hi Omar,

One 'hands on' method would be to write simple AviSynth scripts and load using VirtualDub. VirtualDub is a pretty decent & free video editing tool but there is some learning curve.

For instance, I created an .avs script that loads 3 video files (must be the same dimensions) and uses the "StackHorizontal" function to place them next to one another.

clip1 = AviSource("file1.avi")
clip2 = AviSource("file2.avi")
clip3 = AviSource("file3.avi")
StackHorizontal(clip1, clip2,clip3)

The output can be saved as a single .avi file.
