@rica

What does your out.avs look like? Is has to look like the following, but with the correct number of frames for your situation.

Code:

LoadPlugin("H264StereoSource.dll")
H264StereoSource("decoder.cfg",136392)

Check your actual output file rica. It is 24 fps. It always says 25/1 even when encoding at 23.976. Trust me.

Are you SURE you have the right number of frames in your .avs file as Limobar says?

Yes, i got the info from the left file over eac3to since i cut it.

My actual output file?

WinDVD says it is 25p: check one of my previous posts: (the result of my previous code without --fps 23.976)

http://forum.doom9.org/showpost.php?...5&postcount=95

rica · 14th December 2010, 02:35

OK, the latest code gave 23.976 with --fps 23.976 switch, (even it says it is 25/1)
thanks:

EDIT: But Vegas didn't like that and it doesn't want to open it.

Greetings Limobar.

I'm using two Panasonic HS700 camcorders to record independent left/right 1920x1080/60p h264 mts streams and would like to encode them into single 3840x1080/60p side-by-side video.

Appreciate if you could provide any guidance.

Many thanks and best regards.

Limobar · 14th December 2010, 08:28

@mariner

You could use an Avisynth script like this:

Code:

VideoLeft = directshowsource("C:\x264\left.mkv", audio=false)
VideoRight = directshowsource("C:\x264\right.mkv", audio=false)
VideoStacked = StackHorizontal(VideoRight,VideoLeft)
ConvertToYV12(VideoStacked)

Be aware that all your equipment (Video Card and television) must be HDMI 1.4a compliant, otherwise it probably won't accept 3840x1080. The use of nVidia Vision Video Player is recommended. Other players, like MPC-HC will only show half the resolution.

Thanks for the kind reply, Limobar.

1. Does this work on .mts streams directly? This is way over my head, so would appreciate if you could provide full script.

2. How to select the audio track used?

3. The 3840x1080 video is to be spanned over two projectors, so hdmi 1.4a is not required. Do you know any video card that will decode this is DXVA?

Many thanks.

crl2007 · 14th December 2010, 12:28

1. No, it has to be re-encoded, so you have to use mkv. That is the full script for full SBS. It works on m2ts streams if you have 2 m2ts streams, but you have to re-encode the right eye, so mkv is the only way. You can use SSIFsucka or multiAVCHD, it would be much easier for you if you don't know to handle avs scripts.

2. You merge them in with mkvmerge after you demux them from your blu-ray disc.

3. Any video card that is DXVA capable. As far as I know, the only cards capable of HDMI 1.4a are from nVidia's 4xx series and above and ATI's 5xxx series and above.

Full script for half SBS:

Code:

lv = DirectShowSource("left.mkv")
rv = DirectShowSource("right.mkv")
stacked = StackHorizontal(HorizontalReduceBy2(lv), HorizontalReduceBy2(rv))
ConvertToYV12(stacked)

If you have a video that requires crop, then the script becomes:

Code:

lv = DirectShowSource("left.mkv").crop(crop values)
rv = DirectShowSource("right.mkv").crop(crop values)
stacked = StackHorizontal(HorizontalReduceBy2(lv), HorizontalReduceBy2(rv))
ConvertToYV12(stacked)

BigPines · 15th December 2010, 03:26

Like rica, my right eye video is too short so it is completely useless. It is approximately 30 seconds too short for a 2 hour and 41 min film (I'm sure you can guess which film I am working with). So I am bummed. It seems there is something wrong with the 3D decoder or the x264 encoder. I'm starting to think I am going to have to look for another solution.

UPDATE: eac3to calculated the original length of the video to be 232607 frames. However, once the right eye is encoded, it is only 231893. This is 714 frames short. I am trying to figure out if this could have anything to do with the message from x264 indicating it sees the video as 25 fps even though I forced it to encode at 23.976.

I changed my right.avs file to the following:

LoadPlugin("H264StereoSource.dll")
H264StereoSource("decoder.cfg",232607)
AssumeFPS(23.976)

Let's hope that does the trick. It seems to be working so far. I guess I'll know for sure in approximately 14 hours. :|

rica · 15th December 2010, 12:02

Mike, this code gave me 23,976 but 60 frames are missing again:

Code:

C:\H264StereoSource_a2>x264 --fps 23.976 --level 4.1 --sar 1:1 --aud -o right_new.264 out.avs

crl2007 · 15th December 2010, 12:20

A few frames are bound to be missing. About 2 seconds of film is acceptable to be missing.

Thanks for the reply, crl2007.

1.The source is two complete 1920x1080/60p 28mbps h264 mts streams captures by two Panasonic hs700 camcorder, not 3DBD. A step by step guide to combine these two into a single 3840x1080/60p video would be most appreciated.

3. ATI's UVD2 found in 5 series card cannot cope with these 28mbps 60p streams in DXVA, yielding only 50fps.

While Nvidia's PV4 can deal with it, it remains unclear if it will cope with 3840x1080/60p streams. Feedback will be appreciated.

Many thanks and best regards.

crl2007 · 15th December 2010, 12:54

For 3840x1080 you must use Limobar's avs script. Just that instead of mkv you use m2ts. Directshowsource is capable of opening m2ts streams. Only that you will have a mkv file as a final result.

I have an nvidia 4xx series, but I never tested with 3840x1080/60p over hdmi 1.4a. I don't have a 3dtv.

You mean we alway miss some frames at the end? Can you tell me why? h264stereosource error or source error?

Not sure about that. If it is only 2 seconds cut off the end, I agree but that is not what I am experiencing. If you have 2 seconds of video lag with your audio then that is a different story - not to mention the headaches you will get trying to watch this in 3D. I believe my video speed was increased somehow and I think it is related to the default 25 fps of the detected source.

I know the error at the end is expected but do we know what causes it? Maybe if we understood that, we would understand that it is not normal. *shrug*

Please enlighten me.

Mike

invincible · 15th December 2010, 16:32

I think there're something wrong in cfg file and that's why it miss some frames:

Code:

DisplayDecParams      = 1                # 1: Display parameters; 
ConcealMode           = 0                # Err Concealment(0:Off,1:Frame Copy,2:Motion Copy)
RefPOCGap             = 2                # Reference POC gap (2: IPP (Default), 4: IbP / IpP)
POCGap                = 2                # POC gap (2: IPP /IbP/IpP (Default), 4: IPP with frame skip = 1 etc.)
IntraProfileDeblocking = 1               # Enable Deblocking filter in intra only profiles (0=disable, 1=filter according to SPS parameters)
DecFrmNum             = 0                # Number of frames to be decoded (-n)

BigPines · 15th December 2010, 16:46

Yeah, I looked at that too. I noticed the DecFrmNum setting and wondered if that had anything to do with it. Not sure though because I don't really understand how it all works yet.

Not working. The output was about 100KB. This is what I did:

1. Created a 3D700.avs file with following:

Code:

VideoLeft = directshowsource("D:\3D\left.mts", audio=false)
VideoRight = directshowsource("D:\3D\right.mts", audio=false)
VideoStacked = StackHorizontal(VideoRight,VideoLeft)
ConvertToYV12(VideoStacked)

If you have a nvidia graphic card, please try to run your mts streams through DG Tools. But if you don't have a secondary right eye stream, the stereoscopy is useless, because you will see 2D. The right eye is slightly shifted or lowered for stereoscopy to take place.

Those frames are missed because of the decoder. The guy that made the decoder said that this is normal. We have to deal with it until something better and faster will surface. And free, of course, because with about 5000$ you can have a professional encoder/decoder. I only had 2 seconds missing from an entire movie, never had such problems as to miss more than 2 seconds from the right stream.

But if you don't have a secondary right eye stream, the stereoscopy is useless, because you will see 2D. The right eye is slightly shifted or lowered for stereoscopy to take place. Those frames are missed because of the decoder. The guy that made the decoder said that this is normal. We have to deal with it until something better and faster will surface. And free, of course, because with about 5000$ you can have a professional encoder/decoder. I only had 2 seconds missing from an entire movie, never had such problems as to miss more than 2 seconds from the right stream.
