eddyg: HandBrake Snapshot 4 is now out - which fixes the Windows decomb and deinterlacer.
Cheers, Ed.

Quick question. Since on a quick look for H.264 encoding (which I tend to use) Handbrake calls x264.exe, how is Handbrake different from say MeGui? Let's say you have started with a ts stream recorded from Freeview. Does Handbreak now incorporate the Monogram AAC filter to be able to demux the AAC audio out and then encode is something more friendly?

Thanks

HandBrake does not call x264.exe, HandBrake is a self contained program that links in all the libraries that it uses. For Windows only, the GUI is actually just a front end to HandBrakeCLI which does all the work. The Mac and Linux Guis are linked directly to the HandBrake application. Hopefully Windows will be too soon.

For Freeview it looks like this, assuming you are going from a Freeview MPEG-TS to an MP4 file:

HandBrake reads the file
HandBrake demuxes the stream
HandBrake sends the AAC-LATM to a modified version of ffmpeg to decode
HandBrake sends the H.264 to ffmpeg to decode
HandBrake rewrites the timestamps and syncs the streams
HandBrake crops and resizes the frames
HandBrake applies built in filters such as deinterlace, deblock, smooth
HandBrake sends the video to x264 for encoding
HandBrake sends the audio to faac for encoding
HandBrake muxes the video and audio into an MP4 using mp4v2

Cheers, Ed.

That sounds good so must give it a try. But not clear on this part

HandBrake sends the video to x264 for encoding

Looking at the Handbrake FAQ it seems it does call x264 to encode to AVC/h.264. Not that this is a bad thing since there is huge development in that area and it would be silly to duplicate that

[edit]

On reflection since x264 is open source, you could take the code and compile it any application. Perhaps that is what handbrake does?

Exactly - Handbrake takes all of these open source libraries and calls them directly via their public APIs, not using their stand-alone executable. That way you get better control over configuration, pipelines, and timing.

Well not too successful for me. On Vista with SP1 as soon as I open a ts file (TV3) I get an error
frmReadDVD.cs - startProc()System.OverflowException:Arithmetic operation resulted in an overflow

etc.

This is on a dual core AMD.

I really should post this on the Handbrake forum but I am likely to be pursuing this solution at this time so this just a FYI

This looks as if it is coming from the Windows GUI - Have you tried the Windows CLI as well?
Maybe the Windows GUI (which is just a front end to the CLI) is not correctly parsing the output of the scan for Freeview TS.
If that's the case I need to get the Windows GUI developer to look at it.
Cheers, Ed.

FYI - The WinGUI developer is reproducing this issue - so hopefully it will be fixed soon.
Cheers, Ed.

Thanks to the feedback - that HB WinGUI bug is now squashed. Thanks, Ed.

So when can we expect a binary release of the result?

Tricky to say, because I don't really get a say :) - any day for another snapshot and then soon (a week or so) for a full release. There's a feature freeze on at the moment so that the bugs can get ironed out, which is working well thanks to people like you letting us know when things are broken - which has historically been an issue especially with the Windows releases (even though there are 1.6 Million Windows HB users, which is higher than the 1.5M for the Mac).
Cheers, Ed.

OK - quicker than I anticipated - Snapshot 5 is out now with the Windows fix in it.

I can confirm it finally flawlessly encodes your sample. 60mb down to 10mb, though quality was noticably lost, i couldve dropped it to 720p and it shouldve been perfect for archiving

Used default settings, ticked decomb (no deinterlacing settings), added the AC3 and it encoded. Which setting is best to use now, you mentioned fast had issues, but what should i be using? fast, slow, slowests or just decomb?

Quick question about CRF, i've heard 59% is the new magic number for perfect quality. What kind of file size am i looking at for an average movie encode? Currently im using around 1-1.2gb per movie using h264 2 pass, i think around 1200kb/s, what should i be looking at for similar quality in CRF? Will i be able to get higher quality at 1.2gb using CRF instead?

However by default if no path is specified it writes the file to the doc folder instead of the program directory, source file was in C:\
