adding subs to a clip for testing

[trooper11]

I need some help with some clips im trying to make.

i have been making dvds from avi files for a while. each time though, i have to resize the video and burn it to test the sizing of the subs on tv.

now the problem i have is that now im working with mkv files, where the subs arent hard coded.

what i want to do is add the subs to the avi i pulled form the mkv file so i can load that into tmpg and cut it to the 1 minute clip size i need. i dont want to have to encode the entire video.

is there anyway to load the sub file into tmpg directly? im using tmpg express btw. thanks

extract the subs with virtualdubmod or mkvextractgui. add them using virtualdub and the subfilter and frameserve.

[trooper11]

well i tried that, using frameserve, but tmpg would not start

i set up the vdr file and then loaded that into tmpg and then cut the clip to the length i wanted, resized, then set up output to be the proper dvd format, but when i hit start, it gave me an error saying there was an unsupported format.

Why not just do all your editing(cutting) in VirtualdubMod, saving direct streams. Then demux you subs and author them with the dvd files.

[trooper11]

oh ok, that would work too. how do i cut in virtual dub?

how do i do that to cut both the video and sub file at the same time?

[trooper11]

couldnt i just add the sub file to the stream list and then save the avi file?

what exactly do i need to do to get the subs on the video in vdub so i can then load it into tmpeg. framserving didnt work for me.

Encode the video in TMPGEnc without subs, then add them when you author.

If frameserving with VDub didn't work, then you could try frameserving with AVISynth or load the video via dshow and use ffdshow to render the subs.

If you mean add the subs to the streams list in VDubMod, then no it won't save them to the new avi, only to mkv and ogm's and even if it did, it is still just a seperate stream.

[Stormin Norman]

If your gonna do any editing in vdubmod, you should do it with the sub stream enabled(probally is already when loading original) and do your cutting and joining. Then do direct stream "save as": as a different name and save as your current format(.mkv, .ogm) because it supports multiple streams. Then save video with audio and subs disabled. Then while your there, demux audio, sub streams. Encode avi to dvd compliant, transcode audio to ac3 with ffmpeggui, then author mpeg2, ac3, and srt in authoring program. Depending on authoring program, you might have to author you mpeg and ac3, then convert srt to .sup with Txt2sup and add the .sup to your authored files, then burn. Its easier done than said.

well i mean that sounds like the full thing for encoding video, whihc is not what i need.

what i need to do is just get a short 1 minute clip from some of these vids so i can burn them toa dvd and check how the subs are positioned on a tv screen. i have several differnt videso so im goign to make 1 min clips of each.

what i want to avoid is encoding the entire 30 minutes episodes since that would take a day to do on the system i have. i just want a short clip with the subs hardcoded to it.

if i just cut the clips without hard coding the subs, would they even show up properly? since they would have 30 minutes of subs and the video only runs for a minute? i could author it that way, if the susb will display properly for the video time that is there form the clip.

[trooper11]

ok i have another idea. is there any way i can screen capture the video as its being played? i can simply load up the video with subs displaying and capture it.

now i tried it with snagit but all i get is black screens. is there a certain setting I need to use in order to make capturing possible? thanks.
