While we are discussing GUI complexity can I please request that some attention be paid to the "filters" which can be selected in the "profiles" or in the "preferences". Many of these seem to be historical hangovers, with little/no documentation and odd bugs. In particu...

Thanks for your quick reply. Sorry I forgot to mention the version of windows, you are correct (I've updated the original post with version info). I saw the use of "cmd" in an old example, but it appears to do exactly the opposite of what's needed (ie. it runs the command in the background...

I want to convert a series of MPEG2 files to MP4 (for example), using a windows batch file. *Edit* I am using Windows 7 64 Bit, running VLC 2.1.5 32 bit (for compatibility with Firefox). I have successfully used a command line of the form: vlc.exe "E:\Input Files\Test.mpg" --sout=#transcod...

Thanks for the quick reply. I had not seen the new VLC "stream" menus .... I can see that they now refer to the same named profiles as the "convert" menus. This is a significant improvement. I knew that the "stream" menu provided the parameter string (for editing), but ...

I totally disagree with the earlier comment that it would "complicate" matters if the "Convert/Save" function could handle multiple inputs and multiple outputs. VLC already supports a "Playlist" which therefore means that a list of multiple inputs is available by defaul...

VLC seems to be incapable of performing a "convert/save" to the same video format as the input (it just silently does nothing). Unfortunately it seems to make the assumption that there is nothing to do if the requested output format is the same as the input, regardless of any other prefere...

Can you please let me know what is the current syntax I should use for VLC in a Windows batch file? The various references I can find are old and much has changed in VLC since they were written. I made a couple of attempts, but just got unhelpful error messages. What I would like to do is convert va...

I am running VLC 2.1.3 (64bit) on WIndows 7 64 bit. I have no information as to whether this issue is specific to WIndows, or a general VLC issue. Details of problem: Attempting to transcode MPEG2 to MPEG2 (to reduce the bitrate / filesize) I found that the video "bitrate" field had no eff...

I am running VLC 2.1.3 (64bit) on WIndows 7 64 bit. I have no information as to whether this issue is specific to WIndows, or a general VLC issue. Summary: The "cropadd" filter does not appear to work when the input is MPEG2 video. Background: I have some old 4:3 aspect ratio MPEG2 video (...

I think it is a big mistake to assume that all users have the same cultural background and sense of humour. On the other hand I think it's fair to allow the developers to express themselves if they wish - after all they are doing this for free. And it is not an overtly political or religious symbol.

I am recording output from a security camera. I would like to only record the frames where motion is detected to reduce the amount of stored data. I enabled the "motion detect" video effect filer. But this just seems to add square boxes to the video where it thinks it has detected motion. ...

Nope. VOBs are program stream (PS).

Sorry - my mistake. I should have double-checked what I wrote.

.REC files are TS (from DVB-T).

Glad to hear about the enhancement for VLC 1.2.

Thank you for your reply.

I've no idea what the filter does, but I'll play with it and see what happens!

I too have this problem with DVBT TS files. If I (edit/demux and) re-multiplex them eg. using DVD Author then the resulting VOB files work fine and display time information correctly. This is rather curious as VOBs as just TS files. Obviously VLC understands the DVD specification time codes. Ref &qu...

Is there a way for VLC to convert a (short) piece of video into a series of still frame-dumps? I know VLC can do a snapshot, but this method would be tedious, and I would like to dump each source frame, not some arbitrary display frames. I don't mind what the output format is so long as it retains a...

With reference to (1) above. The MRU list of recently opened URLs for Convert/Streaming is stored in a VLC configuration file. In WIndows this is located at: "C:\Users\<user name>\AppData\Roaming\vlc\vlc-qt-interface.ini" (and probably other similar places too depending on how your machine...

Oh, good, I finally found radio buttons for the four chapters. But they don't play anything. And they only appear when the directory is opened, not when the video file is selected. Chapters are DVD Objects. They are stored in the IFO file of the DVD directory. So if you open the VOB (transport stre...

Thank you.

Sorry I haven't played around with chapters on VLC, though the documenation indicates it should work. [When I've made a DVD with a few episodes/parts, I've always just done each bit as a seperate video (ie. a seperate menu item). It's pretty easy to automate the DVD menu to play menu items seamlessl...

You could try viewing messages (under tools) and setting verbosity level to 2 (or 1).

The log messages should give you a clue as to what VLC is doing and maybe why there is a problem in your case.

I can assure you that VLC does play TS files and has done so very well since before version 0.8 when I first started using it. Note that this thread subject is 8 years old and hasn't been active since until someone posted a spam link. You don't say where your TS came from. You mention getting only a...

It sounds like you may be trying to add a negative delay to the audio. Obviously this is limited by the length of the internal buffer (cache) which is being used. ie. if the buffer is say 300ms (VLC file default) then you can't add a negative delay longer than that (as the video would have already l...

I don't know specifically about VLC and DVD chapters, however I wonder if you are trying too hard here. VLC can play the DVD directly, either directly from the DVD media, or from a folder (just copy the complete DVD files to a folder). Then use either "open disc" or "open folder"...

Well yes, I know that the TS format has PTS (and DTS) fields. However when I use VLC to transcode my network stream to TS and then play it back using VLC all I get in the GUI is "-:-:-/-:-:-". So there's something strange happening either in the recorded file or the VLC playback. To my kno...

I understand. It would be a nice feature if VLC put the timestamp into the TS file which it created. (Presently it leaves the time blank ie. no time shown on playback, no total time value shown. Note that if I re-mux the TS file then VLC will correctly show timestamps which are created by a third-pa...
