The menace in London are people who drive Chelsea tractors. Oversized vehicles whose owners think theyâ(TM)re too good for the TfL. We need to take a leaf out of Paris' book and increase the charges for congestion and emissions, especially in zones 1 and 2, and perhaps even 3 (letâ(TM)s say everything inside and including the north and south circulars.). Cycling is the only sane way to get around this area. Driving isnâ(TM)t an activity that scales and weâ(TM)ve sacrificed enough on that experiment.

Davinci Resolve is wierd, it still can't do AAC on Linux. The last post in this thread was July this year: https://forum.blackmagicdesign...

It's free or cheap because Black Magic are a hardware company. They're not interested in feature parity on all platforms. In fact they're not interested in any codecs and formats that cost them money, hence MainConcept's plugins.

If what you said were true, online video services would use MKV, they can't afford to waste so much moneyÂon a streams that are 140% bigger. But that's not true is it? HLS and MPEG-DASH and CMAF are all based on MP4/base ISO media format (fragmented MP4 to be precise). It wouldn't be in their commercial interests to use such an inefficient format.

I never said it was a codec. It is a file format that offers better compression. That's why a 1920 x 1080 video in an .mkv container is smaller that the same video in .mp4 format

That's simply not true. MP4 and MKV are containers with low overload, unlike MPEG-2 TS where the container overhead can add up to 8-10%, especially for low bitrate audio and video.

Containers have nothing to with how much video is compressed. While MKV can have compressed headers, this makes little difference unless you're dealing with video that is either low resolution or was compressed so much that it has a very poor quality. MP4 does not have 700MB of overhead compared with MKV, and if you're finding that the file sizes are that different, it means the video has been compressed significantly more in the MKV by the video encoder, not the muxer (multiplexer). Or maybe one has used a different codec, such AV1 vs. AVC. Demux your streams and then see what the size of the elemental video streams are if you want proof.

Yes, I work at a codec company. And no, I haven't seen MKV for years, it's a format popular with certain online communities like the DivX crowd or pirates (often the same people).

Comment Re:Sleep monitor? (Score 1) 40

I don't like wearing watches and I haven't for over 25 years. I can't imagine trying to sleep with one on.

Correction: I do wear a watch, when I go running. I've got a Garmin that I've had for about eight years and it's still going strong. I can't see it being replaced by an Apple Watch that costs more and whose battery doesn't last as long.
