Well, if you try to load the SA footage from an mpeg-editor (I use Mpeg Wizard), you get this :

Whole video: 00:40:43:08

Animated video: 00:23:41:04

............from 00:23:41:05 to the end.... BLACK! 17 minutes of nothing!

why the hell ?!?

Can we just cut the unecessary video and keep the m2v smaller than ever ? Or those 17 minutes of nothing, need to syncro the whole video ?

ps: this is from the regular DVD-ROM to Daphne conversion with latest DaphneLoader (have all the originals), I can't compare with previous SA version cause they are splitted in multi-part .m2v footage (I mean the oldy and glory mpeg floating around years ago for 0.99.7 Daphne)

See ya

Hmmm.... I just checked, and it does seem that there is 40 minutes worth of frames there. I have no idea how this happened. The important question is, how much disk space are the extra frames taking up?

Were these encoded with a variable or constant bitrate? If a constant bitratge - it would definitely be a benefit to remove the frames.

hope today to get freetime and handle this .m2v, cutting off the remaining 17 minutes of black video and see what happens...

for sure the disk-space will be resized, but I haven't any clue about how much and if the video results in syncro with .ogg audio and .dat

we'll see

ps: DL & DL2 seems ok, all the .m2v parts are filled of video/data (no idea about TQ coz it's the only DVD-ROM missing :)

Personally, I don't think that more than 100MB would be saved and -for me - is a negligable amount.

Here goes the results:

Original ace.m2v

Format MPEG-2

Size 640 x 480 (1.000 (square sample)

Frame Rate 23.98 Frames/Sec

Bit Rate 10000 kbps (Variable)

Total Lenght 00:40:43:11 ( 2445.90 / 58643 )

File Size 1.01 Gb

Clip Lenght 2445.90 Sec

-----------------------------------------------------

Cutted ace.m2v -

Format MPEG-2

Size 640 x 480 (1.000 (square sample)

Frame Rate 23.98 Frames/Sec

Bit Rate 10000 kbps (Variable)

Total Lenght 00:23:41:05 ( 1422.63 / 34109 )

File Size 986.08 Mb

Clip Lenght 1422.62 Sec

Both fully working with latest Daphne.

In fact, I think that bunch of megs cutted off does not complain the size of the video at all, buuuuuuuuuuuuuut this was just a test and we still asking why the hell all those minutes of black-video in the original DVD-ROM conversion.

See ya folks!

My file is from the official Daphne download release (as it's the recommended file).

Congrats - but I'll keep my version.

Orko,

I was under the impression that you were complaining about the auto-downloaded version of Space Ace that requires a DVD to authenticate. But now I am not so sure. Can you please confirm or deny this?

Sure m8, I confirm.

It was meaning the DVD-ROM > authenticate conversion (if you need I could post the crc32 dat of my DVD-ROM)

mine too, but as I wrote, there are several DVD-ROM version from Digital Leisure, and each one is decrypted from daphneloader (even if authenticated). Scan-proggy, does the right crc's check and reveals if you have a genuine or fake version.

the DVD is used to unlock the footage Daphne uses - your file should be the same as everyone elses. If you are using Windows XP, is your file system FAT32 or NTFS?

if you mean the .bf file, yes, but you need a genuine dvd-rom to decrypt (and I was referring those about "several versions")

Post subject: 
Like I said...It doesn't matter what DVD you use...the file that Daphne plays is the same for everyone - size included (this includes the decrypted files not just the .BF ones). I'm just trying to determine why the size variation of YOUR original file compared to mine - thus the question of either FAT32 or NTFS.
