AVCHD analysing tools

Do we have any idea how much these analyzers cost? If nobody has emailed them yet for pricing and perhaps a discount for this effort (maybe in exchange for advertising?) I can send them an email...

I emailed MiraVid.
As for Tektronix you can do it, but I do not see big chance here.
Both products seem to be extremely pricey.

    MPEG-2 Transport Stream packet analyser enables decoding and low level analysis of ISO/DVB transport streams. It can be used for fault-finding, equipment and system testing, software development and learning more about how MPEG-2 systems work. AVCHD supported.
    MPEG-2 Transport stream analyser is compliant with the following international standards.
    Compliance: ISO/IEC 13818-1, ISO/IEC 13818-2, DVB ETSI EN 300 468, DTG D-Book,

I haven't tried it tho.

I tried this software. Complete crap.
All I get is runtime errors and freezing even during opening.
We need really pro tools as StreamEye is also not developed for quite long time and is amataur.

That's too bad. It provides more information than StreamEye

It works for other compliant streams, from other camcorders, blu-ray, software encoders. Many developers use it.

Something about these firmware modded streams causes it to crash.

I tried it on many MTS files, included unpatched ones and on NEX5 footage.
It either freezed or showed runtimes errors and closed, or showed other strange errors. This is buggy completely unusable software.

Use the raw avc file, demux from transport stream or container. If you have a transport stream, you can use tsmuxer, if you have a .mov container, use yamb.

It works fine on 7D, HMC40 files for example.

It does crash on modded GH1 footage, but not on native GH1 footage. But it doesn't provide as much information on native GH1 footage as it does for other cameras for some reason (it can't read the predicted & residuals)

What system / OS are you running ?

I listed it as an option because many codec developers and testers use this tool.
 
OK, I tried after demuxing on two clips.
It worked with native 24p and 720p60.
Information is hard to get really. Interface is also quite strange.
Stability is non-existant, it just crashes without warning sometimes.

I want to see tool that help you understand how it works, and this one generally require reverse process :)
Anyway it'll be helpful if you can describe info that it shows (manual is also non-existant :) ).

Only useful thing that I get from it is that slices number in 1920 mode is simply calculated from MB total number divided on 360.
 
Exactly what kinds of information you're looking for?

This is a low level stream analyzer that's used usually for software encoder optimization. It's normally used to compare MB pixel info for different streams (e.g. you test a stream with one set of settings , and compare to another). It has PSNR utility, but you need a reference stream (you won't have this with GH1, you would need HD-SDI out and record uncompressed stream to have something to compare to).

I don't understand all the info it shows , but I know many codec developers use it because it's quite comprehensive. I thought you would understand it all :)


The manual is sparse, but you can download it here

It sounded like you wanted something more advanced than StreamEye, well this is it.

Anyways, if it doesn't meet your needs or is unstable for you, time to move on and not waste your time :)

You can get slice number in StreamEye as well

Yes, this tool just helped me to understand possible reason why we have so many slices in 24n.

And I am certainly not codec developer despite that I understand some info :)
For me TS is also quite important and ability to look at correspondent binary data is also good.
So, pro tools are much better.

It's too bad the manual isn't more comprehensive or explains things more clearly ; they assume the user knows all the basics already (I guess this tool is geared to advanced users)
