Hi,

I'm doing a few video tutorials and need help joining a couple of videos. Unfortunately, they're quite high quality and my graphics card won't do it without reducing the quality severely.

They can be found here: http://www.mattireland.org/tuts/c++/c++vidtuts.php

You'd get full credit on my site for joining them.

Thanks very much,

Matt. Ireland

The graphics card does not matter really. It is the software you are using that matters. Also I don't think that variable sizes are limited by the CPU.

Downloaded the files, I'll see if I can make them into a wmv so it can be streamed. I'll post the link when I upload it.

BTW, pretty cool idea and very well written and spoken. I dont know C++ but sounds fancy.

Variable sizes are dictated by the CPU. One can escape that by using around the block solutions (as in a bignum library), but atomic operations are an inextricable part of the hardware design.

Never forget that your machine is characterized by hardware. Software is merely manipulative of the underlying reality.

Matt, I might also suggest using youtube.com to host your videos.

Thanks everybody! Thanks ghost - that's a really good idea. I was thinking of streaming them from my own site but it would save a lot of space and might also increase popularity. Thanks also for your help - I really appreciate it!

@Wizard1988:

I'm using pinnacle studio 10 titanium and that says that I haven't got a good enough graphics card so I immediately assumed that it would be hardware. However, you might well know better...

@DaWei: Thanks also!

Thanks! That's a really good program... but... they have different sampling rates for some odd reason?

Can anyone else please help?

to join the video files together they must be the same size (frame), fps, etc, if you are using vdub, as in the guide posted previously, so it's likely that the videos differ somehow? I didn't check but if that's the case they would need to be re-encoded. alternatively you could use avisynth, it's a "scripting" interface for dealing with video and audio, it allows you to "edit" the video before processing it with the main application (vdub)

an example of joining 2 videos together, with different fps/size etc.

"in.avs" (opens with vdub) Syntax (Toggle Plain Text)

clip1=avisource("some_random.avi", audio=false).Lanczos4Resize(640,480).ConvertToYUY2().ConvertFPS(23.976)
clip2=avisource("different_clip.avi", audio=false).Lanczos4Resize(640,480).ConvertToYUY2().ConvertFPS(23.976)
clip1++clip2

Though I'm not sure if this would cause audio skew (if fps was the case), you'd need to know how the clips differed, you could also just remove the audio like in the example and add that separately.
edit: using avs would need a re-encode too, so it's all the same in the end, i guess, just some time saved..
