What are the in-car video formats?
2 Answers
Car DVD navigators generally support video formats such as WMV, AVI, ASF, 3GP, MP4, and MPEG. Here is relevant information: Car Head Unit: The car head unit is the core component of the in-car audio-visual system, primarily functioning to play audio sources, equivalent to the DVD player in a home theater. However, to better suit the limited space inside a car, the head unit often includes some amplification capability. If the speaker requirements are not too high, there is no need for an external amplifier, making it simpler to set up the audio-visual system. Functions of the Head Unit: Tone adjustment, harmonizing signals across high, mid, and low-frequency ranges for better balance; Loudness adjustment, compensating for signals with insufficient loudness to make the sound fuller; Built-in equalizer, applying different frequency gain enhancements for various music styles. For example, pressing the 'ROCK' button on the panel will enhance bass and treble to emphasize the rock music experience.
When we play videos on the car screen while driving, the common format is MP4 because it has small compression and large capacity, making it suitable for mobile devices. I load videos via the car's USB and find that MP4 files play smoothly and are compatible with most car systems. The AVI format is also good, but the resolution should preferably not exceed 720p, otherwise the playback may stutter. MOV and WMV are also well-supported, but I rarely use them because they are incompatible with some older cars. For safety, I use a tool to directly convert videos downloaded from YouTube into MP4 format. Keep file names simple and easy to recognize. The USB drive should preferably be formatted as FAT32, otherwise the system may not read it. This experience has helped me avoid several embarrassing black screens during trips. Overall, for in-car videos, keep the files lightweight—large files consume memory and may affect driving safety.
