Is it possible to have a mute button just as you do an include/exclude

If H2 supported NULL and PID stripping this would be possible. At the last include you could select an option to drop the audio PID. You would just get the video and the audio would be effectively muted.

Alas, H2 doesn't support NULL and PID stripping.

Is it possible to get it down to tenths of a second?

Anything is possible given enough time, energy, determination, and money. Unfortunately, I'm lacking in all of those.

Seriously, the amount of time between edit points is determined by the number of i-frames in the transport stream. The number of i-frames is determined by the encoder I assume. To edit between i-frames, the GOP(Group Of Pictures) has to be decoded, edited and re-encoded. This would be really hard, not to mention the problems trying to keep the audio synced. Thats one reason why really good TS editors are so expensive and why H2 is free.

Not sure what you mean here...

H2 doesn't support PID stripping yet, although it would be nice if it did. Programs like NullPacketStripper(free) and TSReader($99) can strip PID's like sub-channels and NULL packets from transport streams.

Cris--

I just tried v 1.10.5 for the first time. Great work! Congratulations to all the team of contributors. It really is easy to use now and I especially like the brightness&contrast gadgets for those too-dark scenes that then fade to black.

Here is one glitch I noticed and a suggestion for further noodling:

1. The shortcut keys (which I dearly love!) now interfere with editing the file extension string. I tried to change ".0000.ts" to ".000.tp" and discovered that I couldn't type either a "p" or an "s" in that box--had to paste them to make my edit.

2. Even though it isn't 100% accurate, the scan function usually works and (given that 4:3 commercials are probably not here to stay) I doubt that it's worthwhile to put much effort into improving the edge-detection algorithm. But...it would be more useful as a "first cut" if it were faster. It could be speeded up enormously if the search were to proceed by 1-minute jumps plus interval bisection, rather than frame-by-frame, as it does now.

I used a different technique in implementing the short cut keys than Alan used because I wanted to get rid of the "letters" in the keys. Looks like I missed a box. Should be an easy fix.

Cris,

Could you remind me what are the shortcut keys and what they do?

Thanks,

This is what they should be:

Timeline:
J - forward 1/2 sec
K - forward 10 sec
L - forward 60 sec
F - back 1/2 sec
D - back 10 sec
S - back 60 sec
I - Begin Include
E - Begin Exclude

Edit points:
P - Prev
N - Next
V - move edit point back
M - move edit point forward

Misc:
A - Add files dialog
O - Output file name box
C - convert

Alans original post is here

TPeterson,

PM your address and I will send you the fixed version. If you give it a thumbs up, I will send it to balazer to replace the existing version.

Please,

Call me Jacob. Or at least don't put me in quotes.
post #158 of 2239
Jacob and Cris - thanks so much for keeping this going.

I didn't notice that things were happening in this forum - I mostly watched the HD Recorder forum...

Anways, can't wait to try out the Scan function and see what it does.

Also, a quick feature request if you get a chance...

I noticed that if you add segments, the output filename will change to be based on the filename of the new first segment. Can we have this happen if we delete segments from the list also? Then we would never have to fiddle the output filenames...?

Regardless, great effort, much appreciated!

Cheers!
DAve.

I knew after I posted that it would probably be confusing.

Can I delete WABC 7.1 out of the Channel Stream Info during the convert?
post #160 of 2239
Chris

Another feature I would like to see. I like to put about 5 seconds of pure black video at the beginning and ending of my programs so it doesn't start and stop so abrupt. Looks a little more professional to me. I do this now with a couple files of black video that I put at the beginning and the ending. Would it be possible or feasible to have the program generate black for a series of say 1 sec, 2 sec 5 sec and 10 sec and insert it at any point within the time-line? Some may want to add a short burst of black where the commercials where. Just be a nice to have feature.

I have been using the program for quite some time now. I think you guys have done a great job of enhancing it. Keep up the good work.

If I understand what your saying, this would be part of the PID removal stuff.

What I would like to be able to do is just select the Channel I want to edit, like we do now, and then when converting, remove all of the other Channels from the transport stream and remove the NULL packets.

I now find this tool an indespensible part of my system.

I have found that taking 169time recordings, converting to MPEG2
using HDTVtoMPEG2, then playing back with WinDVD5 is the best way
to play them "glitch free" on the PC. Better than Fusion, VLC or Elecard...

I am still using the 1.10.03 version that Jacob posted a while back with
his fixes. Is 1.10.05 still "just as good" (or even better) in terms of
making good MPEG2 from all sources?

With 1.10.03 the only problem I had was that sometimes the app
would put up a crash dialog part way through some long jobs,
but the disk(s) would keep on writing until it was done. Sortof like
one of the threads crashed but the others kept going.

Do brightness/contrast controls actually change the saved MPEG2 files, or is that just for the little playback window inside of the HDTVtoMPEG2 application?
post #164 of 2239
Here is a history of the 1.10.X versions that I can remember:

1.10.5(Merger of Alan Haverson's code and my own)
NEW:
- Hot key short cuts
- Basic Contrast\\Brightness controls

FIXED:
- Possible freeze during file transitions
- Should also have picked up the fix to the problem with the mpeg conversion creating 3Kb files.

1.10.4
NEW:
- Auto save of region edits
- Mouse wheel steps by i-frame

FIXED:
- >>| Seek to End would not move the bar to the end of the slider
- Crash in Progress dialog when showing progress image
- |<< Seek to beginning would not display first i-frame
- Channel resolutions were sometimes swapped

1.10.3
FIXED:
- Resolution\\FPS\\Aspect Ratio\\Bit Rate not displaying for some transport streams
- No preview picture for some 720p streams
- No preview picture for WB HD transport streams recored with TSReader
- Channel display now favors PSIP data if available and now displays digital and analog channels. If no PSIP data is available, you will get the familiar NONAME channel

In theory, everyone should now be using v1.10.5. It supposedly has all of the fixes that are available. Well, except for the quick fix I did for TPeterson today that he is testing.

The Contrast/Brightness controls are just for the preview window to make it easier to see what your doing.

Does this include the latest conversion to MPEG-2 and back to TS also, or is it considered broke in this version? Thanks.

Mike,

It sounds like your saying H2 could at one time convert a MPEG-2 file to a TS file? I wasn't aware it could do that. I though it was strictly TS file in, TS file or MPEG-2 file out.

Cris
post #169 of 2239
I don't really know for sure, but it acts like it works anyway. I was using Alan's version from December.
post #170 of 2239
Thanks again for all the work guys... And answering questions here.

I am using 1.10.5 now, and all seems well.

Being able to convert MPEG2 back to TS would be nice to have someday...

You need a transport stream multiplexer to convert from program streams to transport streams. Why not just leave everything as transport streams?
post #172 of 2239
Hello all: I'm new to posting here, but have been following along for some time. I've used the latest version ( and BTW, thanks for all the hard work in codeing ) to convert .tr streams from an HDP100 card to mpeg2. If I play the converted mpeg file with ATI's video player I get perfect video, but choppy audio. If I try to play the file with windows media 9 player I get good HD video but no sound at all. I was hopeing to be able to convert HDTV files to HD WM9 files as that would preserves HD quality, but compress the files by about 4 to 1. The process would go .tr to .mpeg then .mpeg to wmv9. I've been sucessful only in getting video converted into wmv9; no audio. ( It looked really good too.) The sampler files in HD of wmv9 are truely impressive to me. HD quality at 5 to 7 mbits/sec. Anyhow, I'd be interested in knowing what the recommended "player" is for the mpeg files produced by H2. If you can vector me to any other forums on this subject or have suggestions, it'd be much appreciated. I got into this a little late, and I've some catching up to do. Thanks

I have started to convert many TS files from my library to raw MPEG2.
They play well with WinDVD5, but someday I might want to turn them
back in TS files for HiPix playback. Pulling out the raw MPEG2 shrinks
the files in one step which is nice.

I know I could use "null-packet-stripper" on the TS files, but I like the one step process of stripping out the wanted PIDs and just saving the minimum needed data for playback.

Oh, and of course I don't trust the muxing on the AVX1 streams very much, so I would just as soon junk that as well.
post #174 of 2239
H2's mpeg conversion still has a lot of problems and is not the best thing to use right now if your trying to get to WM9 format.

The best working solution for taking a transport stream to WM9 is here:
The Comprehensive Windows Media 9 HDTV Encoding Guide

It is very involved, but produces very good results from what I've heard, if you have the time and patience to learn. Sorry I don't know of a short cut that works.

Also, not sure you intended this, but when program alphabetizes the file segments, it will move any file from c: drive to the top, then d: drive, then e: drive etc.

So for example, even if you add in correct order, the program will move them to where you get:

c:\\csi_04.ts
d:\\csi_01.ts
e:\\csi_03.ts
f:\\csi_02.ts

Any chance you could post that "kqed-fix" utility?

Can't find any mention of it on a search ...

thanks

The list box is just doing a standard alpha\
umeric sort(default setting). I assume it was done this way so that you wouldn't have to worry about accidentally selecting the transport streams out of order. You are the first person that I know of that has consecutive streams on different drives. Why?

Cris
post #179 of 2239
I just had a few final files spread over a laptop drive and discovered it when I tried to add the last 3 from the c:\\ drive .... that's all.

Then did it over 4 c:\\;d:\\;e:\\;f:\\ to confirm that it would go by drive letter and then file name in alphabetizing.

Trust me when I say I am overjoyed with the work on the program. This really isn't a biggie at all, but thought I'd mention it here.

Can you elaborate on this? If it completes the MPEG2 conversion without generating any errors is it creating "good" MPEG2? Or is the MPEG2 somehow damaged and worse than what was in the original TS files?
