Fusion HDTV Pro Tuner - 1280 x 720 .tp conversion problems

[oz_surfer]

I have Fusion HDTV Pro Tuner (Australia).

I have captured Ch7 (HD, 1280 x 720, 50FPS, 16X9,9.600Mbs), AC3 (654, BitRate 448kbs, Channels 2, Sampling Rate 48000Hz).

1 Minute = 75Mb

I am trying to find a simpleway to downsize the converting so that it can be saved as a .MPEG file, and then burned as DVD.

VideoReDo will convert to mpeg, but only the sound.

As a person who is employed in the education sector, i have access to certain copyright permissions, one of them being, the recording and distribution of TV programmes, so copyright will not be an issue.

Hey, how did that file extension thing go on the last mpg playback issue you had ?

[mats.hogberg]

Not that I've tried, but what about HDTV2DVD?

I don't think it will do the 50-25fps conversion, mats

Needs an Avisynth SelectEven()

[mats.hogberg]

Probably not, no. Didn't think of that.

To Soopafresh - i sent a recent reply to your last suggestion as a direct reply to the post you sent me.

To mats.hogberg - i have tried HDTV2DVD? - no luck.

Fusion comes with a convertor that converts the streams to .mpeg, DVD, XVid.

What i think the issue is that the tuner For Ch 7, can record in HD (1280 X 720) or Digital (720 x 576). The digital converts easy. Other channels have sizes upto HD 1920 x 1088).

All the digital channels convert, but all the HD chanells don't

What's the codec of the HD stream? Still mpg? Can't you just feed it into some mpg encoder (and reencode to DVD specs mpg video)?

Yes - it is an MPEG encoder

Iamge is from VideoReDo

[oz_surfer]

Sorry - this is the correct image

[mats.hogberg]

Without knowing anything really about this particular kind of video, (but some about video in general) I'd load it in VirtualDubMod and extract the audio stream. Then resize to 720x576, set frame rate to 25 fps + Process every other frame (Video -> Frame Rate) and frameserve to some mpg encoder like MainConcept.

Okay, I believe the following script will work with your files. Download the following app, it includes a very short sample 1280x720p transport stream file for testing.

Click "Download File" Button. 19MB

You must install Avisynth if you haven't already. Not to worry, all of the complexities have been shielded from you.

Double click on _encode.bat to test. The output.mpg file it creates will be PAL DVD ready. You can test it out on your own 720p source files as well, just name your test file "Example.ts" and copy over the one that I originally included.

As you know, the Aus Mpeg2 transport stream can be a bit different than the various other world standards out there. If your example.ts file doesn't work, please cut a 20MB sample and post it to one of the many free file hosting sites out there. We'll get it working, no question

[Soopafresh]

This might work as well. Quality isn't as good, but it is pretty easy. Test it out.

Ideal solution would downscale to 720x576p/50 then encode for a progressive PAL DVD. Or, for a 576i DVD, use an MPeg2 encoder that accepts progressive 720x576p/50 and outputs 720x576i/25 where each field derives from a separate 50p progressive frame.

Aka Avisynth and a decent mpeg2 encoder

The funky part with some Aussie sources is the PID and subchannel placement of the audio track on the transport stream. The tools to demux/index/etc are more limited (but available). Just takes some clicking around. From what I've read, it hasn't been that long for the major broadcasters to transmit in HD, and the structure of some of the TS PID placements have changed during the move from Test Mode to Full Production. Channel 7 in particular sounds like a bit of a mess, especially since the bitrate of 1280x720 streams is in the DVD res range ! (see pic above)
