Files don't play right after encoding with Avidemux.

[ROBO731]

I am trying to hardsub to an mkv using avidemux. I am using avidemux version 2.5.5 since it is the latest version that includes the subtitle option. I open the original mkv file and receive the following message, see picture 1. I click no and the second dialog box opens, see picture 2. I choose yes and it opens the video. For my video option I choose MPEG-4 AVC and I choose copy for audio. I leave the encode mode on Constant Rate Factor (single pass). I then add the ASS subtitle filter along with my subtitle file. I choose MKV as my format and save it. When the process is finished I end up with a longer file than the original and the audio is out of sync with the video, but the subtitles are burned in. I ran the original file and the new file through mediainfo. I noticed several differences that seem like they are important and then there are several of less importance like the names of tracks, etc. The results of the media info scans are below. It seems like an issue that happnes with mpeg audio and that Builiding a VBR time map would help, but the audio is aac. I also don't know how to install MAD (mpeg audio decoder) so that Avidemux can build the time map. So I can't even try it.

I would really appreciate any help anyone can give. If there's anymore information that you need please let me know.

You forgot to set the fps when encoding the video ... you had 23fps and gone to 25fps which is why there's problems.

Note: I wouldn't personally do anything in avidemux with h.264 without converting it to a more compatible form which lessens these issues.

[mgh]

Your original video is shown as 23.976 fps and of duration 23 min 19 sec
Your encoded video is 25 fps and of duration 25 min 20s (something wrong- with 25 fps, the video is speeded up, so should be of less duration than your original)
You can try loading your final mkv in mmg.exe from mkvtoolnix package, and remux. specifically use 23.976 as your fps,
and audio delay as 9 ms (as in original video)

in mmg-select Format specific options- then highlight video stream to access video options- highlight audio stream to access audio options.

If that doesn't work.
Demux the original mkv with MKVExtractGUI-2
re-encode the video with subtitles. Then mux the original audio with reencoded video using mmg.exe as indicated above.

Thanks guys. I hadn't mentioned it, but I had also tried a file with the exact fps of the original, but it came out even longer than this file. I know that avidemux doesn't handle h.264 well. It's just the easiest way to hardsub my file. I'll give the mkvtoolnix suggestions a try and let you guys know how it goes.

[ROBO731]

I tried both of these solutions, but neither worked. Any other ideas?

[davexnet]

I downloaded version 256-1 from here, http://avidemux.razorbyte.com.au/ , but had similar problems.
Perhaps give version 2.60 a try? (build 8266).

I did successfully encode it with Staxrip version 1172. I used FFdshow and activated Subtitles.
Set Staxrip to use directshowsource as the source filter.

[ROBO731]

Thanks, I'll give it a try. The reason I was the older version of avidemux is because the newer version doesn't supported the subtitle filter.

[ROBO731]

I think I'm just going to use handbrake. It gets the job done. It may not be the fastest or the best, but it's the most simple. I have been struggling with this issue of finding a good, easy, fast, high quality way to burn in subtitle for a long time. It seems to me that there is no way like this for the files I'm trying. Hopefully there will be one in the future. Thanks anyway guys.

[davexnet]

I got it to work using Staxrip; perhaps I'll post the output to see if it's what you mean.
By enabling subtitles in FFdshow and using the directshowsource source filter in Staxrip, the subtitles
are merged in automatically through dshow. No need to even address it in Staxrip, they're just picked up automatically.

When I looked at the Staxrip produced file, the ASS subs were there in the file as a separate stream. I ran it through
mkvmerge and deselcted the subs. I played back the resulting file and the subs still appeared, so I I assumed they were
burned in?

[ROBO731]

Yes, they are indeed burned in. I guess I'll give it one more go. Can you give me specific instructions on how you did it? I'm not really sure what you did.

[davexnet]

See if this is file is how it should be (it's 77MB) :

[ROBO731]

Yup, you got it. Can you leave some instructions for how to do it.

[davexnet]

I used Staxrip 1172. I mentioned the process at a high level, but I'll fill in some details.
Install Staxrip. If you see any errors concerning DGdecNV or DGindexNV, see the comment by arto65 on this page.
http://www.techsupportalert.com/best-free-video-encoder.htm

Uninstall or deactivate vobsub if present.
Render the source file with Graphstudio and confirm that FFDshow is the decoder.
Turn on FFdshow's subtitles.

Open Staxrip and under "Filters", deselect all except "source". Right click "source" and choose directshowsource.
Click on "source" (top left) and load your file. On the right where it says "divx plus", (above the white box- right)
click it and choose your x264 profile (I used x264 animation). Set up your audio .
On the bottom right where it defaults to aac 96 vbr, you can click that and
set to "just mux" if you'd like to use the original audio. That's all. Hit "next" and "start"

[ROBO731]

Thanks, I'll give it a try tomorrow (well technically later today lol).
