Latest Nero Express will transcode HD transport streams

[wakebrder]

This is probably old news over at the Nero section, but I thought I would post it here.

After struggling with various programs like HDTV2Mpeg, PVAStrumento, ProjectX, etc, I downloaded the latest Nero suite and Viola! .tp files can be directly transcoded to dvd, nero digital, vcd, svcd, etc. Although the processing time is painfully slow. Around 5 hrs for 1 hr of HDTV.:eek:

I'm in the process of transcoding CSI:NY from last night. I'll let you guys know how it goes.

The latest Nero trial versions can be downloaded here. (http://www.nero.com/us/nero-up.php)

5 hours for 1 hour???? Your rig must be impressive. I get 25 hours for 40 min of HDTV (Imax Antarctica, 1920x1080i) with my Athlon 3600 and HDTV profile.

Not really. P4 2.6 overclocked to 2.9 w/1 GB RAM.

Are you capturing OTA HDTV? I'm sure there are differences in the .tp streams in Spain & the US.

I'm capturing with a Fusion 3 card w/ a (lowly) Radeon 8500. (My 6800 GT is reserved for my gaming rig) Recoding with Nero and cutting commercials with TMPEG Author.

Do they air IMAX movies in HDTV in spain?

Let me know your process.

How are you loading the streams in Nero Recode. I was able to load them into Nero Vision Express, but not into Recode?

Will Nero maintain the DD5.1 audio track within the TS file?

It's one of those mpeg2 transport streams posted in alt.binaries.hdtv, so it comes from US. We have no hdtv broadcasts in Spain (well, maybe a couple of experimental sat channels in Astra).
My hd is full with these IMAX documentaries and the 'Band Of Brothers' series. I'd like to recompress this material and Nero Digital quality is amazing, but it's also painfully slow, as you said.

I am loading them into nero express, but I think Recode is doing the work?:p Look here (http://www.nero.com/us/Nero_Recode_2_Release_Notes.html)

My Fusion card has the option of capturing HD in native .mpg or .tp.

My first test was captured in native .mpg, and the Nero output produced no audio.:angry:

I switched to capturing .tp, and the audio seems to be fine.

I am transcoding Friday's episode of CSI right now. The good news is Nero reported a transcode time of only 1.5 hrs.:D

Obviously, Nero must like the .tp files better than native .mpg.

I'm not sure if CSI broadcast in DD 5.1, but there are audio options in Nero to select it.

Also, Titan Tv allows you to select your capture card in their setup menu. This lets you go into your tv listing, and pre-program your card to record by simply clicking the "record" icon next to your program of choice. Sweet!

I'll keep you guys posted, I'm hoping this process will save people a lot of trouble.

As far as I'm aware NeroVision Express can't generate encodes with 6Ch (5.1) DolbyDigital audio, only 2Ch AC3 @ 192Kbps/48KHz or 2Ch Mpeg1 Layer2 @ 224Kbps/48KHz!


Cheers

Not true. I just finished transcoding "24", and Power DVD reported 5.1 DD on the resulting DVD.
Keep in mind not all programs are broadcast in DD 5.1. Most are just 2 channel.

After I cut out the commercials of my CSI clip with TMPEG author, the audio went out of sync. I suppose I could try and edit the .tp file before transcoding.

I did a test clip of a sporting event that was broadcasted in DD5.1. When I bring the DVD source into a program such as Nero Recode it says it is a DD5.1 source, when I play it back you can tell by the crowd noise that the 5.1 is encoded properly.

1. Record HD .tp stream with Fusion HDTV (DVICO).

2. Edit out commercials with Fusion software. This will leave you with several .tp clips of the program.

3. Start Nero Start Smart > Photo & Video > Make Your Own DVD-Video.

4. Go to Add Video Files. Add your .tp clip(s).

5. Choose a target for your project & burn.

6. I leave the Video options on default (Automatic). 1 pass is 1.5 ~ 2.0 hrs per 1 hr HDTV. 2 pass is 3.0 ~ 5.0 per 1 hr HDTV.

Why is it that my Nero Smart Start does not recognise the .tp files.
I have the latest update for Smart Start, so why the problem with .tp files. Even when I have followed your steps as above.

You can edit the commercials also - in the movie maker portion - and then just transcode to Mp4.

In recode I am getting 1920-1080i HDTV AVC 720p at 7FPS on a P4 3ghz (HT, 512K cache). This is all options MAX EXEPCT FOR SEEK PREDICTION QUALITY is "BEST" not "EXTRA"

If you use extra with AVC you will be literally 3x slower and no gain in quality.

MP4 is by far the most amazing (AVC) format. Crushes XVID and I was a huge xvid fan.

I can't wait for faster dual core AMD cpu's

Thanks for that, but I really need to know why when I use Nero Smart Start it doesn't recognise the .tp files? "wakebrder" has given steps how to achieve this with Smart Start, but I can't get not satisfaction!!

Rename Enterpise_so_sad_its_over.tp to Enterprise.mpg

REcode will see the file - just "add title"

Now, if thats does not work your nero filters are messed up. Use graphedit and make shure your enterprise.mpg is using all AHEAD decoders

It will work

if you ever read the specs you will probably realize that MP4 is by far the
most difficult format to handle ever conceived, full of complications and of useless data, while in AVC there are
incredible ingenuities in the syntax of the bitstream that
were not present in mpeg1/2/4 (excessive resort to golomb-rice
coding, optionality of basic parameters that should never miss such as framerate/timing, etc).
All in all, from a coder's perspective, both MP4 and AVC make you regret the
good old mpegs.
All of the above IMO, of course.

[sjchmura]

I am simply shocked at the quality. Enterprise, with alot of fast moving shots, dark scenes

1920x1080i source ->720p @ 1 Gigabyte/Hour (so 700megs for 40 minutes) is simply stunning using AVC. XVID is so much softer and has so much more blocking.

Can you tell the differnece on the Nero Codec between Best and Ultra search preceision? I simply cannot.

Don't get me wrong - xvid was great and its encoding speed is 1000x faster.

Btw - any suggestions and AVC settings that will keep the quality almost as high as my current 2FPS encodinf on my P4 3ghz :) I keep changing 1 variable at a time but could not find any suggestions or tests of other "options" to disable.

For example, is Off vs low vs High psychosocial enhancement make a big difference?

Any info on how it handles corupted streams, crook Gop's or dropped frames? All part of the Digitial TV capture experience!

[sjchmura]

Literally every ATSC HD stream has some corruption - hard not to. So far I have had no problems with the transcode and the audio actually stays in sync. So far no need to ever reprocess - just AVC is slow as hell :)

[Pyscrow]

Ta for that, It was only of academic interest, I prefer to run SDTV straight to DVD, cant be bothered with HDTV, I dont have a DVD player capable of playing anything better than SD
