Best eyeTV export format for H.264 encoding on different computer?

Before I post this on the Elgato forum, I thought I'd check whether anybody has overcome this here.

I'm using a Mac mini to record the occasional UK Freeview SD video - mainly 720x576 movies that appear to be anamorphic and get converted to 1280x720 H.264 letterbox format that look good enough on my LCD TV. However it's hard work for the old G4 and takes about 12 hours to encode per hour of source material.

I also have a Windows XP dual Athlon box with Quicktime 7 Pro that is running most of the day and I am pretty confident that it can do the job a little bit quicker. However, I cannot work out what format to use when exporting from eyeTV that I can then copy onto the XP box to encode into H.264. It needs to be some kind of uncompressed 'raw' format that retains the widescreen but whatever I've tried so far either cannot be read by QT7 on the PC, ends up 720x576 leterbox with no upscaling, or look rubbish because I've ended up going the eyeTV --> QT movie MPEG4 (out of G4) --> H.264 (out of Athlon) route.

I hope this makes sense. Has anybody else had to do this and perfected a workflow?

1.25GHz G4 Mac mini, Mac OS X (10.4.11), Miglia Micro TV

I have a nice workflow, using a G5 PowerMac and a Windows XP box (Pentium 4 2.4GHz). I use the Windows XP box as the DVR (ATi HDTV wonder + BeyondTV). I live in the US, so I'm recording off-the-air ATSC signals. The recordings are in .ts format (uncompressed MPEG-2). I clean up the commercials with VideoReDo (Something you're spared in the UK. I also trim the front and back of my Doctor Who recordings 🙂

To convert from MPEG-2 .ts to h.264, I've been using Elgato's Turbo.264 on my G5 and I get nearly 30 fps (1 hour = 1 hour). Turbo.264 is not nearly as flexible as VisualHub, but it gets the job done quickly.

Hope this helps!

Commercials? We're not spared those 😟 Mind you, we are with Doctor Who, because that's on BBC 🙂

I'd looked at the Turbo.264, but from the specifications and searching the Elgato forums I was under the impression it couldn't do more than 960x540, and definitely not widescreen/anamorphic. What output resolution are you using?

Sorry to hear about the commercials 😟

Yes, the Turbo.264 has a lot of limitations. It does not do anamorphic encoding and I think you are correct about the maximum resolution of 960x540.

But if your source material is standard definition, then the encoding speed/resolution trade-off is worth it (IMHO).

The output resolution I use for general purpose 4:3 SDTV recordings is 640x480. I've tried 720x400 for 16:9 SDTV material, but the output seemed to have a lot "jaggies" (don't know if this was an encoding problem, or a problem with the AppleTV scaler).

If you open the EyeTV recording package the MPEG-2 files are inside - copy that over to your PC and then convert to the final format.


Aha!

Try MPEGStreamclip for Windows at squared5.com


Thank you!

On the downside, I had to uninstall QT7 (a bit of a waste of money) and use the replacement that MPEGStreamclip recommends because that comes with the MPEG2 decoder for free. The alternative is to purchase the MPEG2 add-on for QT from Apple, which is more money and I haven't seen great comments about this on other forums.

I am also waiting for this post to be removed by the moderators any time now 🙂

I suspect that a future iTunes upgrade might break all this, but since I only tend to stream a few things from the PC I can just use it for conversion from now on.

The good news:

19 minute 544x576 anamorphic (720x576 on screen) clip...

G4 Mac mini + eyeTV AppleTv preset export = 2 hr 45 minutes
Dual Athlon + MPEG Streamclip AppleTv export = 1 hr 39 minutes

Not as big an improvement as I had hoped, but good enough. The eyeTV's preset export to AppleTV, like the one in QT7 Pro, is fixed and "get info" indicates a bitrate of 2.5Mbps. MPEG Streamclip's preset can be tweaked and by default is set to the AppleTv limit of 5Mbps.

There isn't a great difference to my eye, but the latter does look better - then again my sample clip is an old 70s movie so we'll see what happens with other, better source material.

I'm still considering the Turbo.264, but as mentioned earlier it can't quite handle the widescreen anamorphic stuff due to its 960x540 limit. Hopefully they'll come out with a v2.0.

In the meantime, I managed to convert a widescreen SD movie during working hours today, rather than it taking all my waking hours. That's good enough for the time being.

Your MPEG Streamclip solution works for me for now, so I'll flag this thread as "answered".
