God damnit Max. He needs to learn to swallow his pride sometimes and shoot again when the time is right. I love the kid and I think he's doing great, but man he gets heated easily.

Is it possible to extract from the video the velocity profile, gear, and engine rpm over time?
A more refined version might even include position on the track, but this requires a bit of extra effort. #-o

I think this will dramatically improve our ability in comparing cars, performances, set ups and will make the forum a little bit more *technical*. :D :D

It shouldn't be too difficult:
1. extract frame from video
2. cut frame in specified position
3. run digit detector / machine learning / whatever you please
4. plot the results over time

I was thinking to writing some code myself, but then I thought some of you might have already thought about it, might already have access to graphs with all this data, or might be a better coder than me :-)

Cheers

I'm pretty sure something like this has already been done and there's even a python script somwhere on github which runs OCR and then auto plots speed vs time. I think it even did some sort of interpolation between speed readings for better accuracy and easier understaing. Thing is.. i can't find it anymore.

There's also this guy (maybe even the same one who did the script, dunno) who was doing it some time ago, but seems to be inactive now:

Maybe try contacting him how he did it.

Vettel braked too late into turn two and compromised his exit. probably not relaxed as he looks.

My word, if their qualifying pace is indicative of race pace, at least one of the Ferrari cars will be caught by the Red Bulls tomorrow. Even if they get ahead at the start, surely they're too slow to prevent being passed with DRS?
I still can´t understand how RB is faster than Ferrari in this track. This makes clear how bad Ferrari has been here so far. Even if they overtake the Mercedes pair they will be smashed during the race. Hope I am wrong though.

And Hamilton also messed up his last lap too, so maybe he is equally not as relaxed as he looks? :lol:

Disappointing showing from Lewis. Now he's alongside Vettel, and he will show no mercy.
Who will show no mercy? If they both crash and DNF, it's better for Hamilton, as the gap stays the same with one race less. I'd expect Hamilton to be the one showing no mercy.
Well, Hamilton showed no mercy @ Monza - it was a "back off or crash my lad" move. Look how that turned out. With 6 races out, things are far from over.
Disagree, it was a clean and in the light of Vettel's defense that went wrong underrated move. That's why I didn't think it was very bad driving from the latter, it would have been fine against slower and not as well positioned car.

With 5 races to go neither driver has any crashing on purpose strategic advantages, especially with dubious refereeing by Charlie W..

As probably most I'm surprised by the gap between Ferrari and Mercedes. This Q showed also how performance is affected by competition (Hamilton), even limited to one driver and a team-mate.

Red bull wouldn't be faster than ferrari in Q3 with max power. Not on this track.

Perhaps all the rumours about the team not being in harmony are true. Zero unity with everyone doing things their way would result in the sort of shockingly poor setup that they had through FP and quali (and most likely, the race).

It seems for whatever reason that the drivers are either not throwing information at the engineers or the engineers just don't give a damn.

From fastest car, easiest on the tyres; to one that suddenly loves tyre sandwiches for lunch with feet slung up in a lazy chair behind Red Bull is not a great story. Not a great story at all.

However one chooses to deal with it, grief is personal. And it's all slipping away once again. I, like most of us, was hoping for a showdown in Abu Dhabi.

Might also look at the fact that they were running close to Merc for the Championship with Vettel, but after a few hiccups the lead is vanishing. It could be hurt morale and people are just in a 'depressed' state; which absoulutely effects performance that you don't expect.

Ferrari look less composed since the Raikkonen-Leclerc news. The more I watch, the more I think Arrivebene took a gamble on Leclerc's potential, rather than Kimi being old, as he's lost patience with Vettel.

Wasn't Raikkonen half a tenth from pole after two sectors on his last lap, before making a mistake in last sector?
