HD WMV w/5.1 Sound Conversion to iPod Format Problem -- Help Please!

[VixenofVenus]

Ok, so this is my first post here, though I've always been able to find the answer by just being a lurker and doing enough searches here, you guys are all great and knowledgeable!

So, I have a 7.75GB HD Movie in .WMV format with a resolution of 1920x816, bitrate 10200kbps, and FPS of 25. The audio is 5.1 with 384kbps.

I am trying to create a really HIGH quality iPod video conversion for personal use only, since the files will be way too large for anyone else to want :P

Personally, I love using both Videora & SUPER for iPod conversions, and I'm fairly competent using Videora as a power user and editing the conversion profiles to fit my needs, but I can't seem to get past the problem of the 5.1 Sound and ffmpeg having issues with that sound format.

So here is what I would love (but I'll take any help you can give me):

1) Help getting Videora to convert the file, because then I know I can get the settings just right for how I want the file converted. ... or ...
2) Help converting the WMV file so no video quality or audio quality is lost, though the audio is converted to a much more simple Stereo 2-Channel audio.


With any help you give me, please try to be specific so I can follow along ... and any programs you refer me to get, please either provide a link or tell me where I can get it.

Thanks ahead of time!

You could try frameserve using avisynth, install avisynth, open notepad and type
Directshowsource("c:\folder\video.wmv")

Replace the c:\folder\video.wmv" with the location of your video file and save it as video.avs (be sure change to save file type: All files(*.*)).

Open the video.avs in Videora. See http://www.redkawa.com/forums/showthread.php?t=480


Or try convert to ipod using xvid4psp, load the wmv, choose the ipod profile, convert.

Actually ... I found XviD4PSP while waiting for a response and at first I thought it might not really accomplish what I wanted, but I found how to change more of the settings ... very nice program!!

If this works without any Audio-Sync issues, I may have to bear the creator's children ... lol

Thanks for the reply though, and anyone else with any suggestions, they are most welcome!

[VixenofVenus]

Hrm ... ok, so I got this error with XviD4PSP ... if anyone can help ... please do!

? Help Please ?

[Baldrick]

Try change to 1-pass encoding(or quality/quantizer mode), in Xvid4PSP click on the E right to the Video Encoding and change to 1-pass under Encoding mode.

[VixenofVenus]

Alright ... I'll try that, but won't I lose Quality that way? I'd prefer to get the highest quality conversion possible @1500kbps 640x272 ...

I'll try that in the mean time though

Thanks again for all your help Baldrick!

[Baldrick]

2-pass is better yes but I just want to know if you get an error with 1-pass also.

The "b_adapt method specified in stats file not valid"-error doesn't say much....and a google search doesn't give much info.

[VixenofVenus]

I did a quicker 768kbps 640x272 conversion on 1-Pass ... looks good, no audio-sync issues ...

I'll try a two-pass later at a higher bitrate ... but I think you've helped me with an issue I thought I'd never solve ... and I've found a very cool new toy!

XviD4PSP is pretty cool so far ... I'll really have to test it out a bit more though, but so far so good ...


ONE Question though ... how can I get XviD4PSP to do a shortened ENCODE ... for instance, in Videora, I can set the Encoding Duration to a number of seconds which gives me a nice short test of a particular video to encode and I can usually tell if there will be any audio/video issues ...

Can I make a "testing" profile or do something like this in XviD4PSP?

[FulciLives]

I love XVID4PSP but I almost always do 1-pass quantizer type encodes with it yet one time (and so far only this once) I tried a 2-pass encode (setting it to a specific file size output) and it finished without any errors listed in the log screen but my A/V file stopped at around 1 hour 20 minutes on a movie that was about 1 hour 59 minutes.

I could never figure out why it did that ...

[VixenofVenus]

Any ideas for my question though ... I really can't figure out how to do this ... and maybe it's just something I'll have to suggest for a possible feature to add to the program ...

EDIT: One possibility ... is it possible to add a duration to the AVISynth scripting which is conveniently available to the user prior to starting the encoding process? I'm guessing this is how I can accomplish this, but I just don't know how to do it ... lol

[FulciLives]

Trim(0,1500)

Add something like that to the end of the AviSynth script.

The example above will encode from the very first frame to frame 1500 which is about 1 minute.

Trim(0,3000)
This would be 2 minutes.

Trim(0,4500)
This would be 3 minutes and so on ...

By the way the encoder will give you a time estimate based on the full running time of the source file but when it gets to the end frame indicated in the AviSynth script it will end. I just tested it.

P.S.
Attached is a MP4 file using the Trim(0,1500) at the end of the script. It was encoded using XVID4PSP v5.035 using the MP4 iPhone/iTouch profile.
