Apple TV 3 Puzzles

Post by Harry_The_Bustard » Wed Jan 25, 2017 7:33 pm

I record off DVB-T in the UK - which is MPEG-2, 704 x 576, 25 fps with a (varying) bit rate depending on the channel but usually close to 4 Mbps - using an Elgato EyeTV device.

In recent years I used HandBrake - most recently 0.10.5 - and exported the programmes I wanted to keep (naughty I know) using the "Apple TV 3" preset.

With the arrival of the 1.0 version of HandBrake (actually 1.0.2 now) I'm wondering whether the "Apple 1080p30 Surround" preset is best or, given the source, another Apple one with smaller dimensions may suffice. So, if anyone could answer that I'd be grateful.

By way of an aside I did a test export from 0.10.5 with the "Apple TV 3" preset (i.e. as all were exported of late) and the same from 1.0.2 using that preset in the "Legacy" category. To my surprise there were small but significant differences in the bit rate and so file size. I wonder why this is. N.B. I've not included the scan or encode logs as as I doubt such would be of value - rather someone probably knows the answer regardless.

Here is a log for the version 1.0.2 "Apple 1080p30 Surround" encode of an EyeTV version 2.5.3 DVB-T (UK PAL) recording. Let me know if a log for an alternative encode is needed to answer my main question. N.B. I may - or may not - pick up the "aside" later.

The legacy AppleTV 3 preset uses slightly higher video quality, RF 20 compared to 22 in the Apple 1080p30 Surround preset. Feel free to adjust the RF value in small increments such as these after selecting your preset.
