How to convert a 23fps Xvid file that a Daytek 707 can read?

[redkater]

Hi there,

The last 2 weeks I spend every free hour to convert a couple of XVid files to a DVD+RW so I can play them on my stand alone DVD player, without any success.
A file that was encoded in 25 fps Pal was easy converted with Tmpgenc thanks to the guide on this site.
But I tried almost every guide and tool on this site (and others) to get the $#%^^#^@ 23,94fps files readable (yes I read a lot of simular topics in this forum)

The problem Description;
NTSC -> pal conversion gives a jerky file, even played on my PC. ( it looks like it happens every second, maybe the 25th frame?)
NTSC + Pulldown -> reads ok on the PC but on the Daytek it is crap: parts not played, sometimes 'hangs' etc

A lot of people seems to use the Daytek, so how did you guys (or girls) manage to get a decent play on the Daytek 707 ?

more info;
Windows 98 SE
258MB Ram
120GB disk
Nec 1300 DVDburner
tools sofar: TMPgenc, DVD2SVCD, Procoder -> same results.
Nimo codecs, Fddshow codecs -> try seperate installation and together

Please help
Or should I buy a videocard with TV-out?

NTSC->Pal need not play jerky, you just need to do the conversion properly.

Briefly, here is how I would do it.

Open the avi in virtualdub. Select Audio->full processing mode, Conversion to 48Khz (if needed) and Compression = none (PCM), now File->save wav file. This gives you the audio file. You can the encode this to mp2 or Ac3 or keep as wav, but change the length to match 25fps using BeSweet.

Now the video. Still in vdub, select audio->none, video->direct stream copy, Video->Frame rate, change to 25fps.

You now have two choices. Save out the video to a new avi at 25fps using file->save avi (it will have no audio), or frameserve to Tmpgenc.

there is a guide on framserving here

In fact there is a guide on the whole process here

Hi Bugster,


Thanks for your response.
I did some tests and the frameconversion in Virtualdub seems to work great.
After stressing for 2 weeks it's a relief.
Thanks again, I owe you 1

PS The sound is not so good as in the original file (a little bit digital distortion), but I can live with that

Hi Bugster,

PS The sound is not so good as in the original file (a little bit digital distortion), but I can live with that

This is often caused by poor sample rate conversion. Try doing this part of the process with toolame. Its a command line tool tho' so I hope you can figure it out!

Ok Bugster!

Thanks again 8)

Hi Bugster,

Maybe you can help with a new problem that I encountered.
The audio & video are out of sync, only by files with a change of framerate.
There seems to be no errors in the source-avi.

I searched the forum for the same kind of topics but I din not find any usable solution
Since I use the same method as you described I guess you encountered the same problem and found a solution fot that.
Please help me again

Did you adjust the 'framerate' of the audio correctly. Besweet has preset options for doing this.

Hi guys,

for crying out loud, can someone give the command-line string that
beweet uses to change this fps for the audio please ??

thanks,

Yes I seems to work now

Since I needed an MPEG as final result (to put 3 or 4 files on one DVDr)
I tried to convert Wav2Wav with Besweet and it worked with the presettings.

Vhelp - this is the string that was used:

"g:\program files\besweet\BeSweet.exe" -core( -input "f:\han1.wav" -output "f:\hanbesweet1.wav" -2ch ) -ota( -r 23976 25000 ) -ssrc( --twopass ) -profile( ~~~~~ Default Profile ~~~~~ )

May it is useful for you

Hi,

Here is my simple guide ;
How to convert a 23fps Xvid file to a 25 fps .MPG-file
(that standalone DVD players like Daytek 707 can read)
Apx 1 GB for 1 hour of nearly DVD quality

Video
Open the avi in virtualdub
select audio->none
video->direct stream copy
Video->Frame rate, change to 25fps.
Save out the video to a new avi at 25fps using file->save avi (it will have no audio),

Audio A
Now the audio, still in virtualdub,
Select Audio->full processing mode
Conversion to 48Khz (if needed)
Compression = none (PCM)
File->save wav file.

Audio B
Start the BeSweet GUI
Set the path to BeSweet.exe, input and output files.
Select the output format and choose WAV-stereo
Check downsampling if necessary. (normally not needed)
At the OTA section choose Presets NTSC -> PAL (23.976 to 25.000 fps)

Encode & Multiplex
Open Tmpgenc
Load DVD-Pal template
Install Toolame.exe as External audio encoder (options, enviromental setting, external tool, layer-2)
Set Full Screen ( keep aspect ratio)
Save by System (video+audio)
To process more files use Batch encode (save every file as project and add them at the batch)
