Video stalls during rendering batch file. How can i recover it?

[Master Tape]

Been having this problem for a while now where i render a batch file with FFMpeg, but it can stall at any random point. I just left a file to render overnight and it only had a couple of minutes left to render, but it stopped. So now i have an unplayable MP4 4GB file.

How can i recover this file, so i can just render the last few minutes and splice append them together? As i really dont want to start from scratch again only for the same thing to happen. I really need to get a new CPU.

few Questions ..

1 - have you tried more forgiving playback tools like VLC?
2 - Can MPC-BE play it?
3 - can Media Info be generated from it?
4 - Have you ran ffprobe on it? Any output?
5 - is the original file damaged towards the end? seek problems, etc ?
6 - what container is it in? Mkv, Mp4?
some containers handle file corruption better than others. [ex: Mkv, Mov]

Tip for future encoding [rendering]:
- Use a GUI, which can retry, skip, continue or close the already
rendered part with proper headers when failures occur.

VLC or MPC wont play it.

Media Info isn't generating anything besides this

General
Complete name                            : D:\Video.mp4
Format                                   : MPEG-4
Format profile                           : Base Media
Codec ID                                 : isom (isom/iso2/avc1/mp41)
File size                                : 3.72 GiB

Not sure how to use ffprobe.

No, the original file plays fine. It's a 1080i MP4. And is being rendered as an MP4 at 1080p.

Oh the GUI would be handy, and would have saved me alot of hassle before if i knew about it sooner. Thanks for that.

As for the 4Gb file, don't bother trying to recover it.
IMHO, it is not worth the time and effort. just re-encode
the file ..

Try Clever FFmeg-GUI ..

Another free tip : use FFmpeg 8.x, it is faster ..

I'll cut my losses then! Hopefully there'll be no more stalls with the GUI version.

Shame i can't choose libx264 from the drop down menu, it's what i usually use on my batch files. Would x264 (avc) give me the same quality?

Glad they've just released a faster version of FFmpeg, but will need to figure out how to install it, as can't see any installation file in the folder.

In the future use the "-movflags faststart" option.

<EDIT>
Nevermind, doesn't work.

Use one of the MP4/MOV repair programs. They copy the MOOV atom from a similar good file onto the end of the bad one.

x264 (avc) = libx264
but will need to figure out how to install it
I have a script for that ..
