I need serious information down converting WMV/DTS..experts welcomed

[darkmantis]

I recently purchased a screen play pro for my media tank. I soon found out that the device cannot handle higher quality videos that I re-encoded for playback on my computer so I need to convert those to a format that my device can handle. I really do not want to re-rip the dvds, so recoding these movies would be a perfect idea. Of course, in my ripping experiences, I played around with all sorts of file types and a few are in WMV/DTS.

My device requires an AVI container, Mpeg 4 standard codec, Mp3 256 2 channel/ dolby/, or AC3 2 or 6 channel high quality. I have successfully converted most of my standard blu-rays that were in mkv format to this without losing much video quality and they look and sound great on the hdtv.

But, I have a few pesky WMV with DTS audio videos that I cannot, for the life of me convert. They are WMV vc-1 streams. I would like to convert this video into Mpeg 4, avi container and AC3 2 channel or 6 channel 48k 300+kb audio. Using programs like Avanti, format factory, media coder, Super, when converting my wmv/dts into Ac3, I usually get A) Out of sync by 5 seconds or longer (especially down sampling audio to mp3) or B) Sounds great and in sync except the voices are only heard on the right channel!

Here is the information for the audio and video on the file that I am currently trying to convert:

Video
ID : 2
Format : VC-1
Format profile : AP@L3
Codec ID : WVC1
Codec ID/Hint : Microsoft
Description of the codec : Windows Media Video 9 Advanced Profile
Duration : 2h 13mn
Bit rate mode : Variable
Bit rate : 7 451 Kbps
Width : 1 280 pixels
Height : 544 pixels
Display aspect ratio : 2.35
Frame rate : 23.976 fps
Resolution : 24 bits
Colorimetry : 4:2:0
Scan type : Progressive
Bits/(Pixel*Frame) : 0.446
Stream size : 6.96 GiB (90%)
Language : en-us

Audio
ID : 1
Format : WMA3
Format profile : M2
Codec ID : 162
Codec ID/Info : Windows Media Audio 3
Description of the codec : Windows Media Audio 10 Professional - 768 kbps, 48 kHz, 5.1 channel 24 bit 1-pass CBR
Duration : 2h 13mn
Bit rate mode : Constant
Bit rate : 768 Kbps
Channel(s) : 6 channels
Sampling rate : 48.0 KHz
Resolution : 24 bits
Stream size : 735 MiB (9%)
Language : en-us



So, with that information, can someone please help me with? Avi container, Mpeg 4 max 9600 bitrate (can be lower), ac3 2 channel at 48k or mp3 256kb 2channel, dolby stereo (prefer dolby or ac3). I think my device cannot handle 6 channels, but it does play 5.1 dolby just fine.

Some avisynth scripts have worked on different formats in the past, but I can't find anything that will successfully do this. I see so many programs on converting to wmv/dts but not the reverse. Any help will be most appreciated!

ps. If I need to demux the video and audio seperately to convert the audio using a program, can you please let me know what programs to use if not a program that can handle everything.

I think my device cannot handle 6 channels, but it does play 5.1 dolby just fine.

6 channel is the same as 5.1 , and your audio is WMA10pro, not DTS.

Do you need to resize it? or can your device play HD?

DirectShowSource() and avisynth should work fine as input into vdub if you have WMP11 installed. You can encode with xvid and ac3 (ac3acm) in vdub . If there is a problem with the audio channels, you can always remap the channels in avisynth

The much talked about Western Digital TV playback device can play videos from USB devices and it should easily be able to handle your videos without re-encoding. Consider making your life easier and saving tons of time and just buy one of those for about $100. See our ongoing thread about it here:

I have thought about getting the WD player, or better yet, maybe the popcorn or some other nmt that plays HD mkv natively, but right now, I'm broke and my SPP is all I have right now. I would rather have a nmt that contains a hd inside of it like the popcorn, spp or many others out there. Unfortunately, I fell for the mis-representation of what the SPP can actually play that was printed on the backside of the box when I purchased it. Of course it says that it can play mkv, and every other file, but I soon found out that's only true if one computer transcodes the movie and sends the signals via network...whatever! lol. I like the support for the WD player, but I don't like the fact that you need to plug a standalone into it, so that's why I'm thinking more along the lines of a popcorn hour, but that's a different story for a different day..

Yes, poison, it does support HD natively, just not mkv streams because it has an older Sigma chip in it that doesn't support it. I can view 1920 x 1080 easily, as long as it's in an avi container, mpeg 4. I have converted all of my video into that and they look absolutely great but this is the only file that has caused me problems. I have tried vdub but it reports back "asf files are not supported." I have vdub and vdubmod installed currently. I never re-size my video at all, it's always original, as my player can play them correctly. Basically, all I need to do is convert this into what I originally asked, avi container, mpeg 4 standard 9600 br (or under) and ac3 audio. Programs that I have used to convert this either won't accept it because it's an asf file or the audio is always messed up in those 2 ways. I have a host to put an avisynth script in, but I haven't been able to find one or possess the know-how to write the exact script. I used the program from WinnyWindows xvid4psp to create a avisynth script and I tossed that into super but the audio was off. I don't mind learning avisynth but I can't find a good reference page that gets into detail. The wiki page didn't really help me much. I usually learn from examples. if you could toss a script my way, I would be very happy to try it out and if you recommend another program to run the avisynth script in, let me know also. thanks..

Install recent avisynth, and WMP11 or the SDK

Open a text file, type the following and rename the extension from .txt to .avs. Change the path & filenames to match

DirectShowSource("movie.wmv")

Preview the .avs in MPC , or WMP. If there are constant sync issues (not progressively worsening), use the +/- keys to shift the audio, determine the delay. e.g. if it was 500ms delay, add DelayAudio to the script, and recheck for AV sync and adjust.

DirectShowSource("movie.wmv")
DelayAudio(0.5)

Note you could also fix the sync in the encoded avi (after the encoding) if it was a constant sync issue. Just shift the audio with vdub or avidemux

Open the .avs with vdub, and I assume you know the rest of the steps. You don't have to use vdub for the encoding to xvid, but it's proven and stable with a solid track record. But super on the other hand....

If the audio is a progressive sync issue (lengths don't match), has glitches, or is VFR, there are other approaches
