Joining two or more videoclip in a single frame.

[morsan]

I have two videoclips that I would like to be displayed simultaneous - one over the other. I am currently using Studio8 for editing, but I dont see how to do this using that program. I would also like to trim the clips (remove part of top and bottom) before joining them.

If this cant be done in Studio8, can this perhaps be done in VirtualDub?

Best regards, Morten

I would say do it in AviSynth. Ibid:

a1=AVISource("C:morsan1.AVI").Crop(0,0,640,120)
a2=AVISource("C:morsan2.AVI").Crop(0,120,640,0)
StackVertical(a1,a2)

Change the "120" value and you will see how it affects your videos.

I have just downloaded AviSynth and tried a couple of sample scripts - it seems to be a very powerful instrument! But it wont open my clips (DV format).

I have tried several other formats, including MPEG (using the plugins found at avisynth.org) with no problems.

I try to open a DV-file:

AviSource("c:\docs\My Videos\Kompressor.avi")

The result: AVISource: couldn't locate decompressor for fourcc dvsd

Any tip for this situation?

It must be DV type 1. Try to convert it to DV type 2.

I'm not sure if I get this right (never considered the subtler variances of the DV format before). But from what I found out, it seems that I loose audio if I convert to type 2?

Pasted quotas from thetechnozone.com/videobuyersguide/Codecs/Type1-Type2-DV.html :

"Split the DV data into separate audio and video streams, with types auds and vids. This is known as a type-2 file."

and

"In Type 2, the audio data is duplicated in the interleave, which means it must be extracted first, then rewritten in the interleave. This can lead to audio sync problems."

Shouldnt it be better to keep the DV-format as type 1, considering the information quoted?

Last quote:

"In addition, some Direct Show capture software can capture Type 2 DV. An example of this is the Pinnacle StudioDV software. It captures via Direct Show. (The StudioDV hardware is also OHCI compliant.) Yet, the resulting files are Type 2. The difference is they are Type 2 Direct Show DV files."

I use Studio8 for editing, shouldnt the captured clips I have, appear as Type2, regarding to the above quote?

How can I check whether I have Type1 or Type2 format, and how can I convert from one format to another?
