Re: Intel Quick Sync?

Seems to be very confusing if the RF settings aren't compareable to each other. Not only isn't RF scales comparable between different encoders (x264 vs x265 vs QSV), it's not always comparable between different settings on the same encoder! If you use the same encoder and don't change settings too ...

Re: h.265 and GOP-structure

Their answer is kind of hard to decode (to me) but my best guess is that they're saying that the file they got had 3 GOP but that their code incorrectly didn't pick up that x265/Handbrake is using "Open GOP" and as a result their code decides that it's really ONE large closed GOP, presumably it does...

Re: Filesize and x264 Preset

Hello, I recently tested with which x264 Preset I will get the smallest Files. So I set RF to 20 and encoded the same input file with all different x264 Preset settings.

Re: How can I test for successful encode in bash script?

True. But (ever since Maxym added more return codes, IIRC), any known errors will result in a non-zero exit code. HandBrake can't report errors that went by undetected I'm afraid… I guess if one wanted to catch even more failures one way for full encodes might be to compare the run-time for input a...

Re: Slow Encodes on 10.1 w/new proc

Various benchmarks suggests your new processor "should" be on the order of 10-15% slower than the old one, though I expect the massive difference in TDP (35W vs 15W) means the difference will be much larger in anything that runs for extended periods like video encoding, half the speed is by no means...

Re: [RESOLVED] Can I have an mp4v2 option back?

Yes, just changing the "brand" to mp42 fixed it. Go figure.

Here's something thing to consider: Display pixels are always square, so whether it is better to interpolate and resample in the encoder or the playback becomes a pretty minor discussion.
