For movie making, the Viofo A129 Pro does about the best job, and if you don't like overexposed skies then turn EV down a step or two and you will get excellent results in good lighting.
The Thinkware U1000 has a slightly bigger sensor, and might be considered better in some aspects, but it is lacking bitrate so not recommended.
The Nextbase 622 also has a larger sensor and looks better than the A129 Pro at night although I don't think it records more detail and is a bit too new for people to be recommending it, plus it has a few issues like a wobbly mount which is not ideal.
All the dashcams tend to have exposure profiles set for picking up details in shadows and not worrying about the sky, while for movie making you often want it to be the other way around since that tends to look better at first impression, so you might consider using an action camera instead. Not so good when it comes to an accident though, and things like bicycles can get completely lost in the shadows. The Gitup F1 has all the functions required for use as a dashcam but uses action camera like exposure with quite nice results, very different to the Viofo A129 Pro even though it uses the same sensor, it is also available with different field of view lenses.
For maximum dynamic range, the Viofo A119 V3 with HDR firmware is interesting, no over exposure of skies and still plenty of detail in the shadows. Results in the images looking a bit flat, but maybe you can successfully edit it for TV use, it would be interesting to see the results.
