Help with H264 Caps

[Ricey]

Iv had a search about this already but im finding nothing too help me. Sorry if i missed something i just really need the help of the doom9 members :)

Ok im capping BBC HD and its h.264 in a .ts file

I don have the first clue how to encode this.

There are two ways id like to learn how to do it.
encode to x264 720p and to XviD.

I would really be forever grateful if someone could show me what i need to do as all iv ever done before is pdtv, thanks and any help no matter how big or small will be great.

:thanks:

Your uploaded RAR includes only an AC3 audio track. Where is the transport stream?

I've received a TS sample too today, I wonder which demuxers, AviSynth and DirectShow filters exist to read it and how robust they are, specs are:

Sorry about that my bad :thanks:

I've received a TS sample too today, I wonder which demuxers, AviSynth and DirectShow filters exist to read it and how robust they are, specs are: You have to post a TS stream sample!

[neuron2]

There are two ways id like to learn how to do it.
encode to x264 720p and to XviD. It's MBAFF so it works fine in DGAVCDec. It's 1440x1080 interlaced 25fps, so you'll either have to bob it or deinterlace it to get progressive. And then you'll have to resize it to get 720P. You can do both in your Avisynth script. Then you can encode it as desired. For X.264, use Megui. For XviD, use VirtualDub.

[Ricey]

K i can load it into vdub and megui but i keep getting a error
saying that the imag size is too small or something.

[Ricey]

This is the error im getting

http://img176.imageshack.us/img176/5519/errorqk9.png

Script im using

LoadPlugin("F:\Documents and Settings\RiCeY\My Documents\+APPS\dgavcdec100a24\DGAVCDecode.dll")
AVCSource("BBCHD.Preview.Football.dga")
crop(2,2,2,2)
BilinearResize(1280,720) # Bilinear (Soft)

[Atak_Snajpera]

Just use RipBot264

[neuron2]

This is the error im getting

Script im using

LoadPlugin("F:\Documents and Settings\RiCeY\My Documents\+APPS\dgavcdec100a24\DGAVCDecode.dll")
AVCSource("BBCHD.Preview.Football.dga")
crop(2,2,2,2)
BilinearResize(1280,720) # Bilinear (Soft) Don't know about your error because I can't get your image link behind my firewall right now, but the video is interlaced, so you can't just resize it like that without first deinterlacing or bobbing. Didn't you read what I posted above?

[GodofaGap]

Correct script is:


LoadPlugin("F:\Documents and Settings\RiCeY\My Documents\+APPS\dgavcdec100a24\DGAVCDecode.dll")
AVCSource("BBCHD.Preview.Football.dga")
crop(2,2,-2,-2) # <---- correction
BilinearResize(1280,720) # Bilinear (Soft)

Crop(2,2,2,2) creates a 2x2 image, Crop(2,2,-2,-2) chops 2 rows of pixels of each side. For more information about crop look in the avisynth documentation.

If the source is interlaced you must indeed bob or deinterlace before resizing. The only resizing you can do without deinterlacing is Verticalreduceby2.

[Ricey]

so i would have to encode to deinterlace, then encode again to resize? is that what your saying.

Thanks for the help lads i need it :P

No, try this script:

LoadPlugin("F:\Documents and Settings\RiCeY\My Documents\+APPS\dgavcdec100a24\DGAVCDecode.dll")
AVCSource("BBCHD.Preview.Football.dga")
tfm()
LanczosResize(1280,720)

[neuron2]

It's interlaced; tfm() is not the right tool!

tdeint()
LanczosResize(1280,720)

You don't have to encode for each step. Just put them in series in your script as above.

[Ricey]

Nope

avssource could not open one of your files

its line 2

[neuron2]

Find out why it can't open one of your files. Your thinking cap will help you immensely. Look in the DGA file to see the referenced path and see if the file is actually where it is supposed to be. Or maybe you need a full path and you have a (wrong) relative path. Maybe you moved things after you made the DGA or something.

Try remaking the project and script, etc. If still no go, then post the script because we can't read your mind.

iv got it into megui and im encoding to x264 720p but its as slow as ****.... i have a quad core pc with 4gb ram should be better i think..
im only getting 10fps :/

That sounds about right, I have a dual core and I'd probably be getting 4.5 to 5 fps,

[neuron2]

10fps is good for HD decode/deinterlace/resize/re-encode to H.264. Be happy!

Go to bed and check it in the morning.

[Ricey]

so on a quad core 10fps is good?

[neuron2]

Should I duplicate my post or would you be willing to just read it again? :devil:

[Ricey]

bro not trying too be bad im trying to learn how to do something here thats all you know..
I was just sure i could do this faster thats all, but seems like im been flamed here for
asking questions that i need to ask.

I bet there was a time you were like me and knew nothing about this.

[neuron2]

I was just sure i could do this faster thats all If you are so sure, why are you asking me? If you are not sure, why won't you accept my answer? What answer are you looking for?

[PlazzTT]

10fps is definately normal on a quad-core for decoding H264, deinterlacing, and encoding with x264.

Do you know what x264 profile you used in MeGUI? Different x264 settings affect the encoding speed.

(Another good idea is to load the .avs in Media Player Classic before encoding. It will be very slow to playback, but it's to see if the picture quality after de-interlacing is okay)

[Ricey]

Look im sorry if i offended anyone all im doing looking for advise from the people that know
what they are doing. Would 64bit xp make encodes faster?

Thanks for all the help i honestly and truly appreciate it.

If you reduce the resolution you'll get much faster speeds, you can also tweak some of the settings in the encode in megui, what video profile did you choose in megui? What was your file size when you finished or if you didn't what size was megui predicting for it? How long is the clip?
