I bought Sony's Movie Studio Platinum some years ago. I am very satisfied with it. Well worth the price!

Ta - but I can only find a reputable download from Amazon for that.. which is OK, but I'd prefer to be able to trial it for free first....

I think it has to do with the nature of the MP4 video format. It results in extremely high levels of compression and that requires processing the entire video to achieve. Other formats do not compress as much and don't need to evaluate the complete video. They are probably not as lossy either, if at all. Formats used for intermediate storage, before the final version, need to be as lossless as possible to retain quality.

SO would I do better to convert to another format before editing? And if so, what - given that I want to be able to play the final result on a PC?
I guess what I'm trying to find out is what the best format and software is for video editing on a PC? Given that a) I don't want to spend a fortune and b) by "best" a key metric is speed...

Avoid Corel Video Studio - it's nice to use, but slower than a stunned slug on Mogadons.
Avidemux[^] can handle cut and stitch jobs pretty well, provided they are the same size, frame rate, and similar data rate. The interface is poor, but it's effective - particularly if it can copy the video and audio streams instead of re-encoding them.
It's well worth checking if your video card supports CUDA - many video apps can use it to offload the donkey work from the processor to massively parallel GPU, and that can save significant time.

Thanks! I'll give it a try...

Another vote for Avidemux. It has a very clunky interface, but for trimming, joining and/or splitting videos it's quite excellent.

I am no expert, but it is probably re-encoding the clip from the start. This is the simple (but stupid) way to do it. I know you have had other answers, but thought I'd chip in as i had a similar issue some years ago, with MPEG-2 video from a cam-corder that I wanted to trim bits out of, before committing to DVD. I eventually ended up paying for VideoRedo VideoReDo MPEG Video Editor[^] after reading, and confirming, that it somehow [*] blends the end of the first clip with the start of the second, without re-encoding everything after the join.
When I bought it only MPEG-2 was available. I see they have a TV suite that will work on H264 files (the guts of MP4 as I understand it).
[*] Something like: Insert more I-frames, and tweak the GOP count over a few seconds (?) to get the new I-frames synchronised with those of the second clip, then its a straight stream copy.

That looks interesting - thanks!

Have you tried FFMPEG? I was using it last night to trim the beginnings and ends off some MP4s and it was fast and easy. I put the command line into a BAT file and drag the videos onto that. I manually tweak the command line as necessary for start and duration, etc.
- I would love to change the world, but they won’t give me the source code.

I haven't - thanks! Something else to try

Given that so many 'tools' are nothing more than a front-end for either ffmpeg or mencoder, yours is the suggestion I'd have made.

Interestingly I went down this road about a year ago. My requirements were a bit more wide ranging from WebEx screen capture sessions all the way up to crop and chopping clips from GoPro and my Sony HD camcorder.
I ultimately decided on Cyberlink PowerDirector. It's overkill for simple crop and chop clips. Does lean a bit more toward hobbyist/professional end of the spectrum. But I found it balanced in codec abilities, ease, and performance. It has a 7 day free trial. Also handy at remastering and producing the final cuts into multiple formats from H.264 to wmv to mobile friendly formats.
Honestly, I'm not sure you can do chop/cut editing on the fly unless your source and final production are raw uncompressed formats. Compressed formats require recompilation. To use a programmer like comparison, If you have a CSV file with 5 million rows in a zip file (because no one has ever had that happen  ), go in and delete 500k rows from the end of the file, it still requires the file to be rezipped.

This has made my morning for some reason. Love this stuff and it is so relevant, imo.
Code included in the video. I can say I have compiled and ran TensorFlow on ubuntu, then made a clonezilla of the build on my laptop.

What's with the hairdoo? I thought Halloween was over. 
Otherwise, interesting video!

Yes. makes me want to reimage my laptop to play around with this but I would need to make an another clonezilla image of my current OS. I was chosen to be a STEM mentor for a student on my son's high school FIRST robotics team on this project competition [^]
I am wondering if we can use this as the student is, and some of you on CP might remember way back as this was my interest to at one time, predicting and simulating NFL games. Not exactly the "question of tomorrow" but it could use some tech from tomorrow. hhmmmm.

If you are selling your own software and get a request for a quote from a software distributor for a license for a single customer, do you play along or decline? I've been selling directly to the users of my software in the vast majority in the past but did sell a few licenses via distributors. But I didn't see any benefit of doing so in exchange for the expected discount... So today I declined another RFQ from a distributor.

For a single licence? Probably the same as you - a polite decline, with a comment that if they want to set up a licensing agreement with targets and discount levels, you'll be happy to see what they propose.
Distros can be useful - they can reach into customers you haven't met or can't meet, and provided they make a good profit so can you!

Holy man's book takes a short time to devour - then it's gone. (9)
[edit]
Someone (who wishes to remain anonymous for now) has got this, but pointed out a slight issue with the tense. It didn't hinder them though, but perhaps the clue might be better as:
Holy man's book takes a short time to devour and get rid of (9)
if that makes it easier...
[/edit]
This being my first one here, I don’t think this is hard – don’t want you getting stuck and thinking “The new guy doesn’t know what he’s doing!” – but I discovered something while thinking of different puzzles: it’s hard to judge the level of difficulty when working backwards from the answer. They all look easy - but of course most problems do once you know how to solve them.
So here are a few bonus ones – no prizes for these, but I’d be interested to know if they’re as easy as I think they are (I’m sure the first one is!):
1. A bid to oust the President? (3, 2, 5)
2. Is it a bird? Is it a plane? It's a troll! (7)
3. Build a fake type (9)
4. Music an extreme revelation (8)

Difficulty is in the eye of the solver. I've posted clues that I'd worried were far too easy and people have struggled. I've posted clues that I thought were absolutely fiendish and someone's posted the correct answer within a couple of minutes.
I'm sure that many of us will have have had the experience where we've gazed at a crossword for half an hour, written in two answers and given up, only to pick it up the next day and polish it off in a few minutes.
One thing that can be relied on with absolute certainty in the CCC OTD is that whenever the setter declares a clue to be easy, people struggle with it.
It should be noted, by the way, that we can't use the T-word round here.

Yes - as I say, it's really hard to judge when you know the answer already. Solutions to any problem are nearly always obvious in retrospect.

No, not those! Oh, God! You're going to make me say it ... T***derbirds!
To me, it was a rather innovative if somewhat repetitive bit of television but to others it was lazy, ill-considered and pushed the boundaries of plausibility way too far. Let's not discuss it any further or before we know it certain people will be calling each other a snow-globe or a librarian or something and threatening to shoot each other in the faeces or whatever it is that they do. I've said too much already, if there's going to be any further discussion on this matter, let's move it to The Dopebox ...

I'm thinking "eliminate" but it would still have a tense issue with devour.
