I have researched and tested and have found the proper solution to playing any movie or video on the Bolt center display by pushing the Gallery button. :)

First, the movie/video must be in MP4 Format, and only a couple of resolutions will play.
The preferable resolution is 1280 by 720 pixels, which will display and use nearly the entire screen.
higher resolutions will not work. Slightly lower standard resolutions may work, but the picture is too small on the screen.

Unfortunately, very few Utube videos or movies are in the desired resolution.

Fortunately, there is a high quality Freeware program available that can convert virtually all other format videos to the desired 1280 by 720 MP4 format. It is: HD Video Converter Factory, by WonderFox. :)

It is exceptionally easy to use. You select the video to convert. Then you select the MP4 format. Then you slide the selector to the 720P resolution. Then you click the RUN button. It will remember the MP4 format after the first one, but you have to re-select the 720P resolution for each file.

If you wish, you can purchase the Pro version of the program for $25, which allows even higher resolutions, including 1280P and 4k ones, as well as allowing you drag/drop batches of files to be converted.

In addition, WonderFox has DVDRipper Pro for an additional $10, which can convert DVDs and ISO images to any video format.

The first video I converted and have in my Bolt is the drag race between the Bolt and a GTI. That will probably be my favorite for a while. :)

My experience has been different. Some mp4's play, some do not. Resolution is not relevant - even at exactly the same resolution, some play, some don't. I've had no problem getting full screen display of lower-resolution files, so I have no need for conversion software.

I am curious as to why some mp4 files do not play. But not curious enough to do a lot of testing...

I did go so far as to create two 30-minute files using exactly the same capture, recording, and conversion software. Exactly the same settings, resolution (not a typical/standard resolution), frame rate, etc., just different content (two different half-hour TV shows). One played, one did not. This suggests to me that there is may not be an easy answer.

Or, if you want something that works on both Linux, Mac and Windows, and no upsell, go with Handbrake (https://handbrake.fr/downloads.php). Handbrake does not break encryption (you have to go elsewhere for that), but I've never had an issue with a file converted using their "Android HQ" profile.

I have had some mp4 files that did not play, even though they were the full 720P resolution. But when I ran them through the WonderFox Converter, then they did play. It may be some weird condition of compression level being wrong on some files, I am not sure.

Probably the Bolt decoder is not sophisticated enough to handle all of the variants that MP4 files can have.
I also like using the 1280 by 720 resolution so the picture is as large as possible, because us old people need all the help we can get. :)

How do you import those MP4's - via a thumb drive?

Yeah, baxically any standard good quality USB stick up to 64 gb works fine. Bigger ones may work, but I haven't tested any because I am too cheap to spend on one yet. :)

I am playing mp4 music videos so I have a bunch of them so they play in sequence.

Naturally the screen turns off when I am driving but that is understandable as I need to focus on the road.

The music continues to play which is fine with me as I have many mp4 songs.

The issue comes when the car is driving and I want to change to a different screen, the mp4 stops immediately and hence my music stops. Frown

You Can Expand to Full Screen

FYI - You can expand to full screen lower resolution videos that show up smaller than the screen by touching the expand screen icon in the lower left of the screen.

Mp4 is a container. The files (video and sound) are inside and compressed with different codecs. The reason some files dont play is that the bolt doesnt have a full set of codecs installed
Or they don't enable it. If you troll through the FOSS licenses (warning it's long) there are a lot of shared libs compiled in. Including, I noticed, FLAC my favorite format. But you can't play FLAC, unless you do a trick apparently of naming it to .wav. Well anyhow it looks like the format is included but they didn't allow it in the file parsing.

That's what I did a year ago now and still working.
For the video, eveything here is true but, I really cross my fingers that someone will find a way to break the software and let play videos while driving.

GEOhot hear my call!!! Please!!!

I'm sure an exploit can be easily made since we're able to make update by USB stick... So the filsesystem is read/write in someway...

I can guarantee that's not the reason, or at least not the only reason. I have encoded similar files with identical software and settings, and found that one works and the other doesn't in the Bolt.

Is there anyone on the latest software (14.4.2) who can confirm that video playback is still possible?

I just got my car last night, it came with 14.4.2 and I can't seem to get the gallery to even see my video files let alone play them. I don't even have a movies tab in the galley only a pictures tab. I'm thinking this entire feature might have been removed.

Yup...mine's gone after the update. Worked only when in Park so don;t know why they would remove it.

CODECs are important, but (de)muxers are also important. MP4 is a container, yes, but to get things in/out of that container you need to know how to (de)multiplex streams of data. Not all (de)muxers are created equal and some will fail when mixing different brands/authors of (de)muxers. Despite there being a standard, even professional (de)muxer authors will shirk some parts of the MP4 spec cause time=money and they only care until users stop paying them money.

Heck, the CODEC could still be a problem. It's why "MP4" specifies profiles levels so that not every decoder needs to be a swiss army knife. They can just support specific profiles (subset of "MP4" features) and do those well and ignore wasting time effort to handle other features they'll never care about.

This is why there are always reference implementations of anything when it comes to standards. Like reference boards, 3D renderers, codecs, mux/demuxers. These reference implementations are meant to verify spec compatibility and not about the cheapest, fastest way to do something. That's where the implementers differentiate themselves from each other.
