Mini Guide - AVCHD to Anything Using DGAVCdec

[Soopafresh]

s0tt0 - I think they're the same, but Google "MTS vs M2TS" to be sure


avnishb - I've seen that problem. There's something different with the file and DGavcdec doesn't decode it properly. It works using CoreAVC with DirectshowSource, but you need to buy coreavc



dgavcdec_00009.mp4

directshowsource_00009.mp4

[avnishb]

Soopafresh,
Thanks for looking into it. I have one question though all your bat files use DGavcdec. Which file should I run to use CoreAVC ? I have CoreAVC on my computer now.

Thanks
Avnish

[Soopafresh]

I'll write you a batch file to automate it for you. This one outputs to 1024x576. Just edit it to the dimensions that you want.

Soopafresh,
Thanks a lot for your help buddy. You are a great help to everyone on this forum especially for people like me who have zero experience with video editing.

Thanks a lot
Avnish

[Soopafresh]

No problem. Looks like others have reported the same issue to neuron2, author of DGavcdec. Seems to be related to libavcodec.

The *.bat isn't working for me.
I don't get 5 files, just 2: bits0001.mpa and bits0001.mpv

Any idea what's wrong?

[Soopafresh]

Post a .MTS file somewhere.

@Soopafresh

I have Sony Sr12E (PAL) It produces different MTS file for each clip I record. Your DOS copy command for joining the files gives error when xport is run on the joined file.

When converting the files to DVD should I deinterlace or keep it interlaced only? Which a good method for both using avisynth?

In a recent experiment I individulally processed the MTS file using xport to demux and then used CCE to encode to M2v but I had serious issue in A/V sync muxing the files and joining it. Non of the free tools gave me a good join, atlast videoredo was able to solve the problem. I used Tmegenc's MPEG tools to mux individual mpg and then joined it with videoredo which gave me a finished mpg which dvdauthorgui accepted. If only I could join the MTS files properly it would have solved most of the problems of A/V sync.

Any suggestion on the workflow? tools?

Great Help, thanks

Raj

rajkhand - I would try ConvertXtoDVD . It'll really simplify things for you, hopefully. I don't even own an AVCHD camcorder, and there are so many variations to the way these devices save files, I just can't be of much help.

[joviparagon]

OK I have been lurking here reading for about 2 months and registered to day as I really am still in the dark on how to well.......

My cam: Canon HF100 my audio recorder: M-Audio Microtrack 24/96
My system - Athlon 64 X2 Dual Core 4400+ with 2GB Ram and XP pro SP2, 1.75TB HD space.

I want to do a few things I have never tried before.
a 2DVD set and a Blu Ray disc of a live music event
I have most of the Video I need as 8 MTS files, I need to edit in a little footage from youtube to cover memory card changes, and a flub where i stopped recording accidentally.
I also have the complete show on audio in very nice quality 16 bit 48khz wav.
I have saved archive copies of all the raw audio and video to an external 1TB firewire drive.
I want to assemble the audio and video in full HD quality and author a BluRay and then a 2DVD set from them. I do not want to use the cam audio as it is pretty shabby.
I also want to snip out a song or two and post them on youtube to help drag some more footage out of folks who might have filmed my breaks. I want to use the good audio there as well.

Software I am used to using for DVD creation - TMPGEnc DVD Author 2.0, Boilsoft Video Splitter and Joiner.

Software on my machine that I have seldom or never used, some gotten at the recommendation of the videohelp guides - avchd_convert_v6, avisynth 2.5, ffdshow, flash_addon (mencoder), haali media splitter, Nero 8, Sony Vegas 8, TMPGEnc Xpress 4.0 trial, Virtualdub 1.8.1

I am stumped as to a workflow, I am pretty sure I need to edit in HD and then after getting a blu Ray image change some settings to transcode a DVD and then further edit and downgrade for the FLV for Youtube.

I tried the Xpress 4.0 trial but can't figure how to sync up audio so it matches exactly, I put the first vid and the nice audio up but can't match them.

If there is a tool for all this that costs some bucks I am ok with that, just need something that works or some guidance.

All helps greatly appreciated
Dave

Oh and yes I intend to share when it's done

[Soopafresh]

Hi joviparagon - it would help you out if you posted your question as a new thread so more people will read it and contribute their expertise.

What I would do is this:

MTS files ---> AVCHD_CONVERT_V6 ---> Save as Lagarith AVI in VirtualDub

Vegas ---->Load Lagarith AVIs --->Load Separate Audio Track ----> Line up/sync Audio and Video --->Edit

Vegas ----> Render out to Final Lagarith AVI

TmpgencXpress---->Load Final Lagarith AVI----> Convert to HDV for Blu Ray / Convert to h264 MP4 for Youtube

[joviparagon]

A million thanks for the suggestions Soopafresh, this was the thread that seemed closest to my own problems and was the one I refered to the most in trying to work it all out.
I am gonna give your workflow a tryout and it isn't all wine and roses I will start a new thread.
Again my thanks
Dave

[rajkhand]

Ok thanks now only one question

How to join MTS files so A/V sync is maintained?

[Soopafresh]

rajkhand - Maybe TSMuxer . You must change the file extensions to .M2TS for TSmuxer to accept the files. And choose the "Append" button as you add files.I hope it works for you.

[Darkflame]

To start with, Id like to thank Soopafresh for all the help he has given.
I'm probably one of many lerkers looking at this thread after being shocked their new comera exports to a format nearly no-one supports.

The scripts work for me, only I am also suffering from the problem avnishb had, that is, unacceptable image artifacts when converting with DGAVCI.
I have also installed CoreAVC as recomended, but I dont know how to adapt the
"__1920x1080_Same_As_Source.bat"
to use it instead.
Any pointers?

I tried the;
DirectShowSource.bat
Above, but tht didnt seem to do anything but delete the old files. It flashed up and went too quickly for me to read any errors or messages.

(I'll make a sample mts file, and link it in a mo)
www.darkflame.co.uk/00001.mts

[Soopafresh]

Hi Darkflame:

The DirectShow batch file should only leave you with the original .MTS file and an AVS file. It's very different from the other batch files. There's no demuxing or WAV files being created. It runs VERY fast. So, in your case, you should see your 00001.mts and 00001.avs files in the folder. Load the AVS into VirtualDub and voila. Let me know if it doesn't. We'll make it work for you

00001.avi

[Darkflame]

Thanks.
I did actualy try that after making the post, it seemed to load, but I got this error;
http://www.darkflame.co.uk/Image1.jpg
When I tried to play or step forward a few frames.

[Soopafresh]

You have a really old VirtualDub version. Try a later one >v1.7 http://tongari.at/modplus/VirtualDub-1.7.8-modplus-20080304.zip

[Darkflame]

hmz..I was rather out of date.
But I just tried with v1.8.1 and got the same problem

[Soopafresh]

1)The .AVS file should look like this

load_stdcall_plugin("yadif.dll")
DirectShowSource("00001.mts").normalize()
fadein(15).fadeout(15)
Lanczos4Resize(1024,576)

2)Do you have FFdshow installed? Turn off support for h264. You want it to use CoreAVC

3) Reinstall Haali Media Splitter

4)Double click on a .MTS and make sure your PC can play it

[Darkflame]

1)
load_stdcall_plugin("yadif.dll")
DirectShowSource("00001.mts").normalize()
fadein(15).fadeout(15)
Lanczos4Resize(1024,576)

Seems identical.
So the problem must lie elsewhere.

2) I'm pretty sure FFdshow is now removed, I cant see it in the
ControlPanel>>Sound & Audio>>VideoCodecs>>Propertys list.
CoreAVC is installed. (demo version, I'll happly buy that if it works)

3) Reinstalled. done.

4) I cant play it by double clicking..no. Should I be able too? Nothings associated with them.
They load and "play" in DGAVCIndex.exe if I use file>>open.


I'm still getting a crash.
I'm going to try the resulting files on another machine, just to make sure its not a ram/cpu issue.

[Darkflame]

Ok, just done some tests and it works!
It seems it the PC simply wasnt good enough to open it in vdub, probably not enough Ram.

Thanks for all your help, I really should have thought of this earlier.

Theres still one slight issue remains;
My output is clearly interlaced, but the mts file was progressive.
Is the bat file expecting the input interlaced?

[Soopafresh]

It's not interlacing, but perhaps the source is interlaced?

Try this one:

directshowsource_deint.zip

[Darkflame]

The camera is a brand new Panasonic HDC-SD9, it should be outputting to 1080p at 25p.
I'll check in case the default is 1080i or something though.

I'll give that one a go.
I can always deinterlace in Vdub anyway, but Id rather keep a progressive source if it starts that way

[Soopafresh]

Do a test in an evenly lit area and look for interlace artifacts. If you're panning a shot, count to 7 when you go from point A to point B. That will keep your scenes from "strobing". CoreAVC has built in deinterlacing, so it might be masked when you go to play back the .MTS file.

Thanks for this excellent guide, I used your xvid script to create avi files, they play fine on my computer using videolan, but when I tried to open them in virtualdub, it complaints that "cannot locate decompressor for format 'xvid' (unknown)". Are you using a special xvid codec? How do I get virtualdub to open the files so I can join them?

I have installed xvid codec and xvid encoded files using other software like TMPGenc opens fine in virtualdub.

I tried to play output xvid file in media player classic, it also complaints about the missing xvid codec.

Any ideas?

Thanks!

[Onceler2]

I am trying!how do I get an avs file from demuxing the video and audio,I assume that is what I am supposed to be doing.
Just how do I get an avs file,I seem to be missing something here,I have tried demuxing with the gui and also runing the batch files from command prompt.
Please help me to understand.

[Soopafresh]

Hi jiaowangxin - Install Ffdshow and have it decode XVID.


Onceler2 - post one of your .MTS files and I'll take a look.

[jiaowangxin]

Thanks so much for your help! It works now.

Another question, is there any mpeg2 encoder available for virtualdub?

[Soopafresh]

No, but you can feed the AVS files into any Mpeg2 encoder, such as FAVC, TmpgencXpress, ConvertXtoDVD, etc.
