AVISynth splicing many AVCHD clips - is it possible?

[Redrussky]

Hello!

This is my first use of AVISynth. I am trying to convert 1,5 hours of AVCHD clips into DVD format. My source video is in about 200 short clips. I want to splice all files together in a single script. The problem is that I can't merge more than 15 minutes of video in a single script - AVISynth quickly uses up all system memory and throws an exception. (Actually, AVCSource() throws the exception) My PC is Pentium 4, 768 Mb RAM. Is it technically possible to process the whole video at once? What am I doing wrong?

Here is my script:

LoadPlugin("dgavcdecode.dll")
LoadPlugin("LeakKernelDeint.dll")

AVCSource("00001.dga") ++ \
AVCSource("00002.dga") ++ \

...

AVCSource("00200.dga")

LeakKernelDeint(order=1)
BilinearResize(720, 576)

ConvertToYUY2()

You should ask neuron2 at doom9.org. He wrote DGavcdecode

If you cant get it to work with Avisynth, you can always merge all clips together into one with TsMuxer. You may have to rename all extensions to m2ts.

Thank you for the replies!

As a new user at doom9.org, I can't post there until Friday.

Is it in general a good idea to make a single movie from several hundred short clips by splicing them in AVISynth?

I have concerns that AVISynth is not meant to do this task. It has no problem frameserving a single file regardless of its length, but as I add more splices to the script, memory usage explodes. I used both DirectShowSource and AVCSource, they both fail at some point because of memory starvation. If I use DirectShowSource (with CoreAVC and Haali Splitter), the tray becomes full of Haali Splitter icons. Therefore I suppose that for each splice AVISynth at least starts a new instance of decoder - which consumes lots of memory.

So, have you ever successfully used AVISynth for merging many clips together?

After I failed with AVISynth, I demuxed video and audio with xport.exe, then merged the .264 files using the copy command. It also did not work for me... But this is going to be my next question. For now I would like to know whether it is technically possible to use AVISynth for my purpose at all.

Here goes my slightly-insane suggestion of the day :

Wrap all your "NNNNN.ext" video segments in an uncompressed .ZIP archive,
change the extension of the .ZIP, try to open it with Avisynth's DirectShowSource().

So, have you ever successfully used AVISynth for merging many clips together?

Yes, but I have never tried to join more than ten or twelve video segments.
