Combine files with different properties

[dmz]

Greetings,
I have three video files. Each has a different frames per second. Each has a different audio format. Each has different bit rates. One has upper field first, one has lower field first.
Im assuming that I cannot simply drop the three files into the time line and produce one output file (obviously with the lowest bit rate and fps).
Do I assume correct? and if so, how does one combine files with vastly different properties to produce one output file?

Thanks
David

Hi David

Frame Rate—frames per second
Changing this from 30 to 25 will result in removing 25 frames, 1 in 5
Playback may show jerky especially when panning.

You are in Austraila using Pal at 25 fps, do a little test.
Using the libries sample video V10, drag to the timeline the film runs from bottom to top.
Notice the properties are 29 fps NTSC.
Share Create Video File DVD will convert the file to 25 fps.
Play each clip from the library to compare.

Interlacing

Upper and Lower fields, where possible you should try to keep the original field order.
Changing the field order may show as jagged lines within the video.
You should be able to convert to Frame Based which is used for internet and some HD video types.

If you have to change things, change the shortest clip.

Data Rate or Bit Rate
Not a problem and can be altered usually to create a smaller file size allowing it to fit to disc.

Audio
Should not be a problem.

David can you tell us what you are trying to create, a video for the internet or a DVD, or are you working with HD?

Can you provide the properties of these video files and maybe their duration?

I think two of the above are the same...
Anyway they are videos of our band from three different cameras and I want to do a multi angle sort of thing combining bits and pieces.

Hi

A lot of info, you can view the video files properties via Video Studio, simply right click any clip and select properties.?

I asked “David can you tell us what you are trying to create, a video for the internet or a DVD”

Ok
The first appears to be standard Pal DVD 16:9 25fps, Interlaced Upper Field First.
If you are intending to burn a disc then these properties are suitable for burning a DVD. These are the settings you should be using for your final video file.

The second is Mpeg4 progressive using NTSC standards
Widescreen 16:9 1440 x 1080 at 29.97fps

The third is Quicktime Mov AVCHD 23.976fps progressive.

The only issue is the frame rates 25fps, 23.97fps and 29.97fps

Combining these videos may/will show some playback issues.

One of the three will be the main video, ideally the longest would be used for the final video retaining those properties.
For a DVD then the first should be used.

So are you trying to make a DVD disc?

Combining these will show some playback issues, whether these are noticeable or acceptable really depends on the video content, if the video was quite static with little panning then the effect will be minimal.
Beauty is in the eye of the beholder………..give it a go.

Once you have the project constructed you can create different video files to see which is best, for the internet that is, for a Disc you are stuck with the first type, Pal DVD
