.mpeg to h264

I have few .mpeg files which are aproximately 1 hour long and weight around 10 giga each.
I'd like to convert them into mp4 h264, but Handbrake doesn't even open them (it gets stuck at 0% while loading). Could you please suggest me another software or way I could convert them?
Also, the videos are anamorphic 1440x1080. Would you recommend me to convert them into 1920x1080 with pixel ratio 1 or is it better to keep the same parameters?
Thank you for your attenction

You can use clever FFmpeg-GUI.

I would mantain the actual resolution.
If again the file cannot be loaded, please post a mediainfo report (text mode) of the mpeg file here.

Takla, I aint no ffmpeg expert, but looks like your solution is simple remux to mkv, he want to re-encode as x264.

EDIT: To takla below. Oooo, I see.

Oh I know. But with my solution he can make the file readable by handbrake 👍
(I probably should have said that though, lol)

Thank you so much for you advice. I didn't like FFmpeg-GUI very much since it doesn't have many options like HandBrake (for instance, I was looking for the Variable BitRate ) or maybe it's just me that I'm not very skilled and I can't find it. Also, it looked like it was taking a very long time to convert the videos (and I'm not sure it was exporting the audio as well I decided to abort because it was taking too much)

Thank you very much, it helped me a lot (and also I learnt something new). I think I will go study this FFmpeg better

sorry, it's me again. I thought I had this covered, but there's an issue with the conversion.
On 3 conversions I had these results:
1) the mpeg and the mkv are both 54:09 long
2) the mpeg is 1:05:09 long and the converted mkv is 1:02:25
3) the mpeg is 1:01:02 while the mkv is 57:36

It looks like there are no missing scenes in the converted videos, since the initial and the ending scenes are there. Also the FPS of the converted are the same of the original videos, I really don't get where are the missing minutes.

The following are the logs:

What software did you use to check the video length before converting with ffmpeg?

With an mkv container you could have an audio stream offset, which would make the files playduration longer then the actual video. But since the video is longer BEFORE it is muxed into an mkv, my only guess is that what ever software you used to measure the .mpeg playtime, is simply inaccurate.

As long as there are no missing frames and audio is in sync I wouldn't worry about it. ffmpeg is usually very accurate.

The encoding time is exactely the same as with the ffmpeg commandline.

Audio can be converted or muxed as is.

The ones that have these corrupt packets, possibly have dropped frames resulting in different duration

You can try "fixing" them first with tsdoctor, videoredo quickstream fix

Out of interest... What does MediaInfo report about the MPEG-2 sources?

According to the MediaInfo file report, the .mpeg file extension is actually incorrect as this is used for 'program streams'. Your sources are in-fact 'transport streams' so a .ts file extension should be used.

Transport streams are quite different to program streams as they are used for less reliable forms of transmission (ie: terrestrial and satellite broadcasts) and as such they have to be chopped into typically 188-byte sections or 'packets' in order for them to be more resistant to errors.

Sufficed to say, if your streams contain any errors this will interfere with the re-encoding process. So if you first run your streams through an application such as: TSremux or HDTVtoMPEG this should help...

EDIT: VideoHelp offers links to quite a few 'Transport Stream' tools
