ts/mkv? Apple’s encoder only encodes to .mov, .m4v, or .mp4, all of which can be transferable between each other. I am pretty sure that QT doesn’t have any real support for tranpsort streams.

MainConcept full definitely allows changing and customizing frame size, but I am not sure if this might be a limit in the demo. In any case, I did try to see what the max frame size the retail version can encode to and it appears to be only 1920×1080.

I am pretty sure ProCoder doesn’t support this resoltuion. You would need something like the MainConcept MPEG Encoder.

ProCoder is the closest for the PC in that price range (sub $500), although there hasn’t been an update in almost two years so QT7 support is pretty shoddy. For about $1K though, you can get the new app from the developers of ProCoder, called Carbon. It has much better support for the newer formats that have been released/updated in the past few years.

Most of the encodes on apple.com are encoded by Apple themselves. They are “true” H.264 files, just that most often they are included in a .mov wrapper in order to better support web embedding and metadata. In order to verify .mp4 compatibility, all you would have to do is open one of the .mov H.264 encodes and select Export to MPEG-4 and choose the option for pass-through for both the video and audio.

.m2v is an extension for MPEG-2 video elementary streams. What you want to likely encode to is a .mpeg, .mpg, .ts, or .m2t. What is probably happening on your encodes from Compressor is that you are compressing to elementary .m2v and .aiff or .ac3 streams. If you were to mux the .m2v and .aiff streams together and play this back in QT, you would hear audio. But if you mux .m2v and .ac3 together, then you would not hear audio as QT for some continued assinine reason doesn’t read AC3 tracks in MPEG program or transport streams.
In order to mux the elementary streams together, I would suggest using MPEG StreamClip. Its free and as long as the .m2v and .ac3 or .aiff have the same file names, it will automatically recognize the two and mux them together so that you can export a valid .mpeg stream. To verify the audio is in the resulting .mpeg, either open the file back up in MPEG StreamClip or VLC and play it.

Tested on a PC here w/ a 8Mbit connection and it does indeed not load as fast as it probably should. I would seriously think about lowering the resolution to 480×360 or 320×240. The quality should still be very good and you could lower your bitrate to something like 1200Kbps or lower and have better loading results.

What is your PVR software? I use EyeTV a lot on my macs and the demuxing is very fast with it. For separate MPEG files, try MPEG StreamClip. It should be able to demux your video very quickly.
-
No, MPEG StreamClip will demux the audio and video automatically when exporting from MPEG-1 to QT. I have done this many a number of times and it has always worked. Maybe there is some issue with your file, but this does definitely work.

Go for it then. If it is just a matter or changing the header, which it could be if the encoding parameters didn’t negate something from one profile to the other, then a simple editing of the binary should be sufficient. You wouldn’t even need to write anything, just download a binary editor and you would be good.
