hard copy subs without changing codec fast

[Ceesar]

Hi

Im looking for a program with which i can hardcopy subs into a new file without changing the codec. and i want to do it fast
I already have MKV Merge. problem with this one is that the file is no longer usable on the PSP, which i am hardcopying it for.

in short
h264 file no subs -->(5 minutes later)--> h264 file with subs

Impossible.

You have to re-encode to do this and there's no way to do that in less than several hours.

MkvMerge simply muxes. It won't give you hard subs. Turn off the compressed headers feature (I forget exactly what it's called) and the file will probably play on the PS3. I don't know if it will display the soft subs though. If you have to reencode with hard subs use x264 with the "veryfast" or "ultrafast" profile. Try Xvid4Psp.

The problem with this is that the subs sometimes dont get synced well with the video, even though i sync it when its 2 files. when i make one out of it, it sometimes changes the timing of the subs completely.
e.g. there is only a intro song and you read what is said after an hour. but when i check the SRT it doesnt show any flaws.

Now, with a program like MKV Merge i have the subs and video in 1 file and i can sync it in relatively low amount of time. If it turns out something is wrong i know after between 2 and 10 minutes instead of 5 hours. and changing and syncing everything perfectly takes about an hour a film instead of a day. thats why im looking for something like MKVmerge.

BTW, what do you mean that MKVmerge doesnt give hard subs. i have one video file with the subs in it after using the program.


'in short

"Impossible.

MKVMerge does that, doesnt it? on the PC this works fine.
But its when i want to watch them on the PSP/PS3 that i encounter the problems

BTW, what do you mean that MKVmerge doesnt give hard subs.

Hard subs are "burned" into the video. This requires decompressing the video, drawing the subs onto each frame, and recompressing the video. You can't adjust the timing of hard subs after the fact -- the subs are part of the picture. MkvMerge simply muxes the subs as another stream alongside the video stream. They are still "soft" subs.

[Ceesar]

i dont quite get that because i end up with only 1 file. if i see everything isnt synced well i do the proces all over again.

do you mean that in a hard subbed video file, the subs cannot be extracted?


and the problem with AnyVideoConverter is that sometimes the subs are synced with the voices but the voices not with the picture, you know what i mean?

[filmboss80]

Ceesar, you don't want to hard sub. If the subs are timed well to the audio, leave them alone. You need to look for ways to sync the picture to the audio and subs. This may involve demuxing and changing the audio stream to CBR (if it is VBR) and/or shifting the timing of the video to better match the audio and subs. AviDemux might be a better tool for you.

[Ceesar]

yet again i am left with questions, not answers.

my source files:
file #1: Video and audio( synced)
file #2: Subtitles (Synced)
So the 2 files above are synced and can be used on my mediadecoder on the pc.
-->
AnyVideoConverter
-->
my new file:
file #1: Video, audio and subtitles
If i am lucky all three are synced, leaving a good result
If i am unlucky 2 of 3 are synced and the other isnt.


What i want is to sync a video file fast with the subs. so that even if it does go wrong, it wont be an entire night or afternoon wasted waiting for this to happen.
if it has gone wrong and it is an easy fix to use the AviDemux than thats oké, as long as i can do it fast.

the above stated by filmboss seams a time consuming enterprise, is that so?

[filmboss80]

Not what I was trying to say. There are ways to demux video and audio streams, then change only the audio stream to CBR (instead of VBR). Audio conversions are fast. There is no need for a time-consuming, quality-diminishing video conversion. After you remux the new audio file back in with the subs and video stream, see what happens. If there are still sync problems, come back here.

Go under the Tools section of this site and type "matroska" in the search box. Forget AnyVideoConverter.

[Ceesar]

so...
you're saying:

Convert the video files and add the subs while converting so that, even if it goes wrong, i can demux using avidemux to set the whole thing straight.
I'm gonna need a manual though for that avidemux program :S

Another thing:
The already converted videos i converted using AVC are converted using CBR. just wanted to say that

Huh? Where did I say that? Honestly, I give up.

This right?
but i dont need to change the audio thing because it is already CBR right?

As I understand it the PSP doesn't support soft subs whether they are separate files or muxed into the video file. You will have to go through the slow precess of adding hard subs and recompressing the video.

[Ceesar]

Thats too bad because that isnt always relyable.

and the whole point of this topic is that i want to add subs to my videos. so if its hard or soft subs, it doesnt matter as long as my PSP/ PS3 can read them.

[jagabo]

You can try muxing your soft subs into the MP4 with Yamb. But I'm pretty sure the PSP won't display them.

[Ceesar]

Sadly, that is correct.
but that isnt the only problem.

now my PC doesnt even display the soft subs


i think ill change a few settings at vobsub, hopefully that will allow me to watch vids with soft subs
