RE: DVGRAB/XDVPLAY testing

[Arne S. <ar...@sc...>]

I thought resp. was an abbreviation for "or". But it seems not to. If I think 
about it, it is even longer than the original word. Maybe it is a german 
abbreviation.

The beach AVIs are the known good ones, if these do not play then it is a 
problem with the player software or the codec.
This theory does not explain though why the dvgrab created type2 AVI plays and 
the reference AVI fails on your NT box.

On my NT 4.0 SP5 system the playback of DV AVIs is very sluggish. Actually 
unuseable. The hardware is a bit better (AMD 400 / 96 MByte vs. AMD 333 / 64 
MByte on the Windows98SE/Linux system). I am not sure whether this is an effect 
of the AVI format or a general feature of Windows NT. Playback of AVIs under 
W98SE is flawless though.

dvgrab --format dv1 --frames 25 type1_ resp

?? What is the resp at the end?

Anyway, results of my testing under NT 4.0:

			WMP		RP_Ver.7

type1_001.avi	fails		fails

type 2_001.avi	plays		plays

beach_type1.avi	fails		fails

beach_type2.avi	audio		audio
			only		only

I'll try these out tonight under 98SE at home.

BTW - I think that 1 second clips will make it difficult to see if things
are running at the right speed. They're too short to tell if they are 1,
1.5, or 2 seconds long.

Cheers,
Mark

Gread idea. I have just uploaded 4 different AVI scenes:

http://www.schirmacher.de/arne/samples/

in dvgrab: one Type-1 and one Type-2 AVI files, PAL, 25 fps, 25 frames (1
second)

The command line was dvgrab --format dv1 --frames 25 type1_ resp. dvgrab
--format dv2 --frames 25 type2_

in ulead: one Type-1 and one Type-2 AVI files, PAL, 25 fps, 25 frames (1
second)
I created these files with ULead 3.0 completely on the Windows98 box,
including
grabbing the raw source material. No dvgrab was involved. The two files show

the same scene.

I would consider the ULead generated AVIs as "the reference" (I don't have
any
other commercial grade DV Editing program, though I would like to use some
of
the real expensive programs to create my reference files).

I can host about 250 MByte of test data, that's my limit for the website.
Should be sufficient. I doubt however that testing a huge file would give
any
more information than testing a short one.

Could you create a NTSC version of such test files? 2 files created by
dvgrab
(30 frames for NTSC) and 2 files created by some Windows Application.


Regarding you new compatibility list:

1. Windows 98 plays both Type-1 and Type-2 NTSC AVIs generated by dvgrab.
Great. The speed is correct too?

2. Windows NT fails with Type-1 NTSC AVIs, Type-2 NTSC AVIS play at half
speed.
I would like to try your AVIs here on my NT system.

3. RealPlayer Windows and Linux: The Linux version certainly doesn't have
the
right codec. I could not get RealPlayer to display my ULead AVIs too. So
maybe
this is not a dvgrab problem.

4. Quicktime: I need to reactivate my old PowerMac 7500 again...
