If graphedit shows ok,
.....then try loading into my virtualdub
Just drop the mp4 onto my virtualdub, and it should automatically pick the correct plugin to use etc

Just for anyone else reading
Problem's solved
Disabling the "pdt ipp" codecs that come with the flip hd software
Getting haali's media splitter working
Getting ffdshow video and audio codecs set for h264 + aac (or coreavc if you have it, for video)
And bob's the family relative of your choice

Thanks for your help, time and patience Karl. Without Karl's help I would had been very lost. I hope to someday be able to help somebody else like this.

| QUOTE (dloneranger @ Aug 27 2010, 11:24 PM) | Just tried, and both methods of adding large batches work with mp4's here
That's
1)the batch wizard
2)the job control dialog. menu->edit->process directory |
Can I get in on the Karl help desk?
I'm trying to batch process MP4s - using Directshow input plugin, to make a AVI with ffdshow Mpeg-4 compression.
#1 If I use the Batch Wizard, it shows the output file as .MP4 - can I just rename the extension to AVI on the output files?
#2 "Process Directory" actually works, thanks for the suggestion. I'm having issues with the compression, though - most of the output files are about 30% smaller than the original - but some are almost double the size of the original! This is with one pass, 85% Quality compression setting. I guess that's a separate issue from the batch processing, though.
Thanks,
Matt |

#1
Yes you can just rename the finished files to .avi
As far as I remember, this is in the list of 'things to be fixed' already (but I've re-reported it just in case)
#2
The problem you are seeing is due to using a quality mode
In this mode, the video takes as much size is it needs to reproduce it at (in your example) 85%
Now, you'd think that'd make the file smaller, but as you see, it can be larger
It can be extremely larger, if the source is very bad quality for example
Sounds odd, but if the source is low quality, and the codecs trying to reproduce a similar quality, it actually has to go to some efforts to 'accurately' reproduce the blockiness, and general awfulness
For these, you're better off either (in no particular order)
1) Leaving them alone
2) Using filters to clean them up
3) Using a 'size' method for compression instead of 'quality'
Compressing interlaced video as progressive, without deintelacing it first, can also make larger files, as the codec struggles to reproduce all the combed lines
Use the deinterlace filter, or if that doesn't produce the correct results, see if the encoder you choose has an 'encode interlaced' option

Cool, thanks for the fast response!
I'm processing 1080P videos - they have an average bitrate of ~17 Mbps.
The max setting for the average bitrate compression is 10 Mbps, I tried it and it made the file about 40% smaller. I feel this might be too much compression... Any suggestions for compression settings? Would 2 pass help? Quantizer? Different encoder?
Thanks,
Matt |

Compression settings vary depending on the codec used - you haven't mentioned which you are using 
Settings will vary depending on the source video
The best way to check the finished quality is still by eye, % differences don't really mean a lot
eg a 40% reduction could mean either a) it's over compressed and bad quality now, or the source was under compressed
If the finished video looks ok with the 40% reduction, then there's no reason to make it larger just for the sake of it
(of course, you could encode the same video with a variety of settings and then compare them, to get a feel for the differences)
x264 currently gives greater compression for a given file size
(depending on which version you use you'll have a few settings to play with, or pages and pages of settings)
2 pass generally is used for getting a file to hit an exact size
If you're using a bitrate based encoding type, you'll usually get better quality from 2 passes
Using the filters can change how much bitrate is needed
eg
the smoother filter, with the right setting, can reduce the bitrate needed, without visually compromising the picture (there's 101 smoothing filters... I like 2d cleaner personally)
msu smart deblocking, can work miracles on over compressed sources
In the end though, you'll end up with looking at the finished video to decide if it's over compressed
