HDTV2DVD, WOMBLE, What programs shouldi use with my .ts files?

HDTV2DVD
Hello ive been capturing video from my motorola dct6412 box for a week now and am a little confused on what software i should be using. ok i heard that hdtv2dvd converts hdtv material to dvd specs. i dont capture hdtv, i capture sdtv. Now my quesion is Are most standard def captures dvd compatible?? and also what specs should i look at to see if the capture is in dvd specs already.
And if it is already in dvd specs,and i use hdtv2mpeg, does hdtv2mpeg just convert this file to mpeg or does it rencode or transcode the file like hdtv2dvd? or should i not even be using hdtv2mpeg for my SDTV captures because i heard it creates A/V sync issues?

Can someone please give me suggestions here?


also what program could i use or how do i get the video bitrate for a .ts file?


and which is better. Editing out commericials with the .ts file or the resulting mpeg file after using hdtv2dvd/hdtv2mpeg?

Well for editing I would recommend VideoReDo. It will work on the .ts or mpeg. Do your editing first.

HDTV2DVD will process SD mpegs as long as they are transport streams.

As long as you have 720x480 video at 9000kbs or lower you only need to convert to a mpeg program stream (and then author with your authoring software)... So VideoReDo is good for this conversion (as it is a muxing exercise rather then reencoding).

MediaInfo, Gspot will give you the details about your source files.

Try HDTV2DVD and SVCD2DVD (Demo) as the latter will do the same but will also just do the muxing (like VRD) if you have as TS @ 720x480, 9000kbs.

Someone told me this

I sometimes run into cases where Womble introduces audio/video sync problems after editing. This is usually for "bad" .ts captures where there is some fundamental problem. HDTV2DVD seems to deal with these "bad" .ts files better while re-encoding and thus keeps audio/video in sync.So the safer method is just take unedited .ts through HDTV2DVD and then edit the .mpg later with Womble to remove commercials.

Is this true? Why do you suggest editting first?
And also why do you suggest videoredo instead of mpeg video wizard?
Does videoredo have manual cutting out of the .mpg instead of automatic commeercial cutting and is it frame accurate?


that same person told me this

hdtv2dvd doesn't give you any control over bitrate or any other encoding settings. It uses a variable bit-rate with peak of 7800Mbps

Does this mean hdtv2dvd will make SD a higher bitrate than the original SD file? and that wouldnt improve quality right? that would just make the file bigger?

Why does it have to be 9000kbs, isnt that a very low bitrate? when hdtv2dvd makes dvd mpegs that are in dvd specs, the bitrate is 7800mb i think so why does my SD have to be 9000kb to be in dvd specs?
What is muxing? Is Muxing all my SD has to go through to be authored?
And doesnt womble do muxing too, its called multiplexing right?

MediaInfo, Gspot will give you the details about your source files.

are you sure gspot works with .ts files because i could have sworn it wouldnt take my .ts file last night

I have no idea about the fact that womble introduces av sync issues but "someone" is correct about HDTV2DVD and its ability to maintain sync. VideoReDo does too. I suggest VideoRedo because it does all of the the things you mention and it does them well (from a technical point of view)

The reason i suggest editing first is that if there are problems after editing you know that the editing introduced the issues.... Your mileage may vary with this approach.

Correct. The assumtion of the tool is that you are loading up HD material and so the bitrate is usually well over 10Mbs - hence you are reducing bitrate not increasing it..... That said, the "Auto Fit" feature implies that if the duration of the assets are such that at 7800 you would go over the DVDR capacity, the bitrate is reduced so that the output does not go over the capaticy.

As long as you have 720x480 video at 9000kbs or lower you only need to convert to a mpeg program stream (and then author with your authoring software)... So VideoReDo is good for this conversion (as it is a muxing exercise rather then reencoding).

"9000kbs or lower": to be sure of compliance:



Muxing: Yes it is multiplexing. What i am saying here is to go from a mpeg PS from a mpeg TS is a muxing process rather than a encoding one. I'm sure womble can do it but i have not used it for years.

Well Gspot does take my TS files but doesn't show the bitrate 100% of the time.... Where a lot of identifying programs fail - MPC always comes up trumps:

If you want to do HDTV to MPG/DVD, VideoReDo is very useful. I have
tried several tools, like HDTV2MPG, HDTV2DVD, and etc. VideoReDo
is the only tool to fix A/V sync problem in the original .ts stream,
caused by signal drop or mixed video programs (like ad). I always
use "QuickFixStream" to extract A/V synced MPG from .ts first.

Hey Media player classic worked for the bitrate, thanks.

VideoReDo

How can videoredo fix a/v sync issues, does it have an option in the program to fix a/v sync issues? and what is signal drop and ad?

I always use "QuickFixStream" to extract A/V synced MPG from .ts first.

why do you do this, what does this do. sorry, im not to technical. can you explain in non technical terms?




So if i have SD Captures that are in dvd specs already and under 9mb video bitrate then there would be no need to using hdtv2dvd. I could just use Videoredo to cut out any part of the video, then videoredo can convert Standard definition transport stream to program stream(or in other words muxing or multiplexing), so i can author this video?

were there any cases that when cutting out video with videoredo, it causes a/v sync issues? what is the latest version of videoredo?

[xxiangg]

OK, let me say first that my working flow is to feed either DV or
MPG to Pinnacle Studio 9 for editing, add manu, then burn DVD.
(I know many people have problems with Pinnacle product. But it
happen to be that the product has worked for me for years.) So
I always want to convert whatever video source to either MPG or
DV, then go with the normal Pinnacle/Studio flow to get final DVD.

For HDTV video, the important thing for me is to find a good tool
to convert .ts file to MPG or DV for Pinnacle to edit. I tried
several tools to extract MPG from .ts files. I found all tools
I tried produced MPG with A/V sync problem, except VideoReDo.
Then, I read somewhere that there are two main reasons causing
A/V sync for HDTV. The first one is signal drop-off. If you
record OTA HDTV and your reception condition is not perfect,
your recorded .ts has some bad data signals. The bad data can
cause A/V out-off sync. The second cause of the problem is due to
mixed contends. Your recorded video very likely has main program,
as well as several different commercial ad inserted in the middle.
All these different video contents may originally produced at
different place, by different equipment, with different video
audio standards, and etc. So the signal itself has some variations.
These variations can cause A/V out-off sync. When I extra MPG using
VideoReDo, there is a report at the end giving you some data about
what A/V re-sync the tool has done. In addition, it looks like
the MPG extracted by VideoReDo has no A/V sync problem. So I use
VideoReDo as the first step of my HDTV flow.

[mikej3131]

hmmm xxiang,
Do you use videoredo to rencode to dvd specs instead of hdtv2dvd?

I found all tools I tried produced MPG with A/V sync problem

did you have a/v sync issues with hdtv2dvd?
Do you cut out commercials with videoredo or pinnacle?

When I extra MPG using
VideoReDo, there is a report at the end giving you some data about what A/V re-sync the tool has done. In addition, it looks like the MPG extracted by VideoReDo has no A/V sync problem. so i use VideoReDo as the first step of my HDTV flow.

So If i use hdtv2dvd to rencode my video, do you think i should cut out my commercials with videoredo before using hdtv2dvd or cut out the video with videoredo after i put it through hdtv2dvd?

[ChrissyBoy]

mikej3131: What are the specs you your videos?

So If i use hdtv2dvd to rencode my video, do you think i should cut out my commercials with videoredo before using hdtv2dvd or cut out the video with videoredo after i put it through hdtv2dvd?

I use VideoReDo to just extract MPG which has no A/V
sync problem. I tried HDTV2MPG and had A/V sync problem.
I also tried Mpeg2Repair and had no luck. I only had
luck with VideoReDo. I do not use VideoReDo to editing.
Once I got MPEG2 from VideoReDo, I go 2-ways. If possible,
I feed the MPEG to pinnacle for editing and burn DVD.
BUt pinnacle is poor in MPEG handling. It may or may not
work. It it does not work, I feed MPEG to VirtualDup
and resize the video to 720x480 @29.97fps using PicVideo
codes to generate AVI file. I have never had problems
with pinnacle using AVI. And the A/V sync every well.
(But last HDTV capture for Oscar show was 6 hours long.
I did get A/V sync problem after 2 hours. Total 6 hours
A/V sync is about 45 frames (1.5sec). SO I separate
Audio and Video to 2 streams. In pinnacle, I cut 2-3
frames every 10-15 minutes. So I still got a good
final results in 3 DVD's. I know my flow is not very
efficient. But I run jobs over night. I do not wait
there for immediate results.

[xxiangg]

Oh, I need to make it more precise. Most of the A/V sync problem
for captured video is video running faster than audio. So I cut
a couple of frames length audio once a while. I did not cut video.

[mikej3131]

I do not use VideoReDo to editing.

What do you use for cutting out video? and if you dont use anything, can you recomend any program to cut video which doesnt produce a/v syns issues????


hey chrissy boy i deleted the SD captures i had on my Pc but tomorow i am gonna capture an hour of HD and see what i can do with this. Probably just gonna put it through hdtv2dvd first. I am getting mixed opinions on wether i should cut out commercials first before hdtv2dvd or after hdtv2dvd so i dont know, i might try both.

[xxiangg]

Several years ago when I used Dazzle DVCII for capture
and editing in MPG, frequently I found the resulting
video has A/V sync problem. After I switched to DV flow,
I have never had A/V sync problem. So I know if I can
convert HDTV to a/v sync AVI/DV, I will not have any
problem during editing. Let me explain what I did for HDTV.

1. Load .ts to VideoReDo to extract MPG, producing A/V
sync problem free MPG in its original resolution (so
no re-encoding here). I also tried other tools for
this step, the resulting MPG had A/V sync problem
for other tools.

2. Load MPG to virtualdup to extract audio AC3.

3. Load AC3 to BeLight, converting it to WAV. (I do
not have AC3 capable Pinnacle Studio).

4. Load WAV as audio and original MPG as video in
virtualdup and converting them to AVI using PicVideo
codec. Following tasks also performed during the
coversion, i.e., resizing HD resulotion to SD
resulotion (720x480), converting frame rate to
29.97fps, cutting black boundary in the video.

5. Load AVI to Studio, editing commercial out, add manu,
then burn to final DVD's.

So I do not use VideoReDo for editing. It just happened
that I am used to use Pinnacle for editing, and it is
working for me. I know that this process is not very
efficient. But I always got acceptable results. I have
spent tons of time in the past try to fix A/V sync
problem before I go through DV/Studio flow. This flow
takes a significant amount of CPU resource. But the
result is almost always predictable.

Ok im goin to use videoredo right now. so i go to file load and load my video, now where is the option to extract to mpg?


@chrissyboy

What are the specs you your videos?

Well i was just gonna post some specs on a HD capture for ya but after i captured with capdvhs i noticed the file wouldnt play with any program so i checked the channel on the tv i recorded it from and it was 5c protection . Is there anyway to bypass this protection?

[xxiangg]

Tools -> QuickStreamFix.

[mikej3131]

oh i thought "quickstreamfix" was for a/v sync issues. is that just for making the .ts to a mpeg?


Do you kow anything about that 5c and getting past it xxiang?

[xxiangg]

Yes, it is used to fix A/V sync problem. It is also used to extract MPG from .ts.
I used the option for both to get a A/V sync problem free MPG. And I always
got a summary at the end of the process, statubg number of A/V re-sync has
been done during MPG extraction. I tried other tools. This tool is the only one
let me get a good MPG file. Once I had a good MPG to start with, I have less
problems in the subsequent process. If I started with a MPG having A/V sync
problem and try to fix the problem during the subsequent process, it is very
hard.

[mikej3131]

at theend when you get a summary of the process, Does it show if there were any erros?

capture fine hd2dvd works fine, plays in computer fine;however, dvd player says no disc. tried several dvd players including latest one on market by Samsung. tried other computers works fine with Media player. converted from .ts to MPEG fine. pleas help
