.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 Last edited by keeper182; 27th July 2022 at 16:41. |

You can use clever FFmpeg-GUI.
https://forum.doom9.org/showthread.php?t=181206 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. Last edited by ProWo; 27th July 2022 at 10:09. |

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.

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: video 1 Quote:

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. Last edited by takla; 31st July 2022 at 13:11. |

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

That's why I obtained huge files that are the recording of the whole cassettes. Maybe I could have imported files with separated chapters for every footage, I don't know if that was possible, my only hope is that I haven't lost quality from the cassettes. Now, I'd like to convert these files because I'm pretty sure I can have almost the same quality for way smaller files (now they are around 10-12 giga for like 1 hour of 1440x1080 resolution), also in order to get better performances in the video editor if I decide to edit the footages. I tried TsRemux, there are 3 formats for the output: TS, M2TS and BlueRay. I remuxed the mpeg to TS, but still got a file with different lenght from the original. Should I do something different? Instead, HDTVtoMPEG doesn't even open the mpeg format Quote:

Did you change the file extension from (the incorrect) .mpeg to (the correct) .ts?

Now I did it and I still get a new file with different lenght.... BUT I did what I should have done since the beginning: take time to watch the footage carefully and I found that sometimes there are scenes that are repeated during several seconds. If I move the slider on the player back and forth sometimes they disappear or it gets stuck. I believe those are the deleted frames that are missing from the original lenght. Thank you very much for helping a newbie, I appreciate |

If the HDV-cassettes are still there, I would capture new.
There were not many safely working HDV-Capturing softwares out there. I remember to have tried my way through and found only 2 softwares to be working reliably: Mainconcept HDV capturing and Sony Vegas HDV capture. With other softwares drop-outs and corruptions were not uncommon.

Ah, good old DV25; 720x480 of 4:1:1 color (in NTSC). The convolutions we had to run through to make DV25 (4:1:1) into DVD (4:2:0) for the lovely net color space of 4:1:0. (The trick was to do titling and graphics on-computer without ever rendering back to DV25). |

Getting OT, but do you have any idea why 4:1:1 was chosen for NTSC mode instead of 4:2:0? I'd like to slap that engineer / committee with a nice big trout
