The VideoLAN Forums

I think VLC, which is already a prefered streaming and playing solution, must become a prefered transcoading solution too.


These are the features that would be welcome in the vlc's transcoader:

1. A better GUIed wizard with more options on the formats, bitrate, vbr/abr/cbr, timeframe, framerate.

2. Options for enhancing the quality(postprocessing?) of video, audio before transcoading.

3. Corping video as in a video editor, with ability to use a slider to corp video

4. Auto corp, to remove the black bars on the borders of some video.(dead useful in reducing the size)

5. Intelligent transcoder that tells the user that beyond a certain value for bitrate, the quality wont become higher because for the chosen raw file, this and that is the max quality

6. Option to suggest the user different codecs for different perposes, keeping in mind the size of video. for example - you may suggest divx, xvid, etc for dvd perpose, flv for posting to youtube, mp4 format for iPods, and H.264 + HE-ACC + MP4 for maximum quality and size reduction.

7. Ability to convert contentents of an entire folder to another format without increase in size and decrease in quality, and original file deletion

8. drag and drop interface for transcoading

9. intelligent wizard convertng a file to another format resulting in maximum reduction in size and no reduction in quality(automatically choose codecs, bitrates, FPS, etc along with container)

10. Information about usability of different codecs and lots of suggestions.

11. a help file

12. ability to split and join videos, audios

13. ablity to join even non similar videos/audios and combine them to a different format(useful with live recordings...

14. ability to specify what to do with each file(apply blah blah blah format/bitrate to one, halb halb halb format/bitrate to another, and process them all together(have dinner and see your job ready)

15. This is the best(and easiest) feature yet: save the settings for the output(for instance, you can save a setting for that 320Xsomething, 20 fps, 44 kbps HE-ACC along with 256 kbps H.264, for just suffitient to see template, MP3 mono audio 128 kbps for those with old mp3 players who share the earphones, etc

16. automatic file name extention for chosen container and option to choose the extention if more than one are possible for the same file(asf, wma & wm for windows media audio, etc)

17. Most Importantly, this feature must gain more prominence, as VLC doesn't prominently display this feature due to which many are in ignorance that vlc can transcode

18. VLC can be able replace audio/video tracks in a file? It will be useful for adding better audio to youtube videos

19. ability to apply equiliser effects to a file before transcoading.

20. ability to add subtitles into a file and then transcoading it.

21. ability to add/remove audio tracks and subtitles... the remove part is the most useful, as we can reduce the size by a huge amount.

22. Ability to create compresed files( ex: 7z files from waw files). useful for those wanting a wav coppy in their comp. (but I recomend flac...)

23. ability to save a transcoading job

24. if vlc could make it possible to add visualisations to audio it would be awssome, as you could have goom in your dvd player....

25. a tag editor, which edits multiple types of tags(real, vorbis text, id3, etc) will also be welcome. one can put in fresh tags to a transcoaded file, along with album art. this is much useful in syncronising different tags, as some files have multiple tags with different information

26. VLC can also have a transcode while playing option. this saves people from the boredom of waiting till the log transcoading job is over.

27. transcode all files from a playlist file.

28. if vlc can out put all converted files, from a list of files to a single folder in the same format, without we having to specify a file name and extention.
this is useful when say we have an mp3 player and drag and drop a bunch of audio or even video files to the transcoder's window and ask it to convert them all to mp3 with the out put folder being the mp3 player's directory. if this is used with the automatically detect minumum required bitrate for each file for no reduction in quality feature I requested, vlc can be a boon to all those people who have primitive mp3 players that play nothing other than mp3. No AAC, no OGG Vorbis, No WMA, No FLAC, No ATRAC, NO VIDEO TOO.

29. and now for a request that most will want: can a playlist be transcoaded while it is playing? I hate to wait 1.5 hours to rip a DVD, but watching the movie while ripping will be awssome. all I need is a load of popcorn and food, along with a more comfortable chair.

30. if you have noticed on a windows desktop, left clicking the mouse, holding it and draging it will produce a rectangle. can a similar methord be used to corp videos in vlc?

31. borrow code from OpenSource softwares like VirtualDub which have some features I asked for(thanks to hschulze for this one)

----------------------------------------------------------------------------------------------


If you have more suggestions relating to the transcoading capabilities of VLC, please post them here.

Is it OK if I add to this?

2. Options for enhancing the quality(postprocessing?) of video, audio before transcoading.

Also the ability to set the post-processing to a higher level for computers that can handle it.

4. Auto corp, to remove the black bars on the borders of some video.(dead useful in reducing the size)

This might go well with this request: viewtopic.php?t=33342
For fullscreen anyway.

7. Ability to convert contentents of an entire folder to another format without increase in size and decrease in quality, and original file deletion

Useful when ripping a DVD (that you own) from its original MPEG-2 format to something like Xvid or H.264 format.

8. drag and drop editing

What exactly do you mean by this one?

9. intelligent wizard convertng a file to another format resulting in maximum reduction in size and no reduction in quality(automatically choose codecs, bitrates, FPS, etc along with container)

Pretty much what I said about #7.

Pretty much what I said about #7.

1. yes it is(I am trying to expand this as much as possible)

2. sure... or you can just process a video twice(the old long methord)

3. maybe... a good media player MUST recoganise black bars and their perpose( I don't know yet anything that does though )

4. XviD is out. H.264 is in

5.you know just drag and drop fies to a window for processing

6. yup.... I think the alogrithm can be easily written If you sit around for some time with a calculator...(H.264 rox along with HE-ACC and aoTuV Ogg Vorbis)

1. ability to specify what to do with each file(apply blah blah blah format/bitrate to one, halb halb halb format/bitrate to another, and process them all together(have dinner and see your job ready)

Most of the things are doable now with VLC, but lack a GUI (1/)
2/ possible

3/ GUI related too

4/ hmm... needs to be developped

5/ Gui related once again

6/ I might add something already for 0.9.0, IF I got time.

7/ ...

8/ ?

9/ same as 6 to me

10/ 11/ Help is easy to write.

automatic file name extention for chosen container and option to choose the extention if more than one are possible for the same file(asf, wma & wm for windows media audio, etc)

what about replacing audio/video tracks in a file? useful for adding better audio to youtube videos

10/ 11/ Help is easy to write.

great! can I help?

ability to apply equiliser effects to a file before transcoading

ability to add subtitles into a file and then transcoading it

sbility to create compresed files( ex: 7z files from waw files). useful for those wanting a wav coppy in their comp. (but I recomend flac... )

ability to save a transcoading job

hey j-b, do you think I have to wait for vlc 2.0 for these many features?

if vlc could make it possible to add visualisations to audio it would be awssome, as you could have goon in your dvd player....

a tag editor, which edits multiple types of tags(real, vorbis text, id3, etc) will also be welcome. one can put in fresh tags to a transcoaded file, along with album art. this is much useful in syncronising different tags, as some files have multiple tags with different information

phew.... one often tends to notice that one's thread tends to go unnoticed when the requests are too many all I can do is to add more and more stuff here for personal pleasure

if vlc could make it possible to add visualisations to audio it would be awssome, as you could have goon in your dvd player....

make it goom not goon sorry

Do you know the edit options of your posts ?

VLC can also have a transcode while playing option. this saves people from the boredom of waiting till the log transcoading job is over.

Do you know the edit options of your posts ?

what? oh you meen goon ? sorry forgot

hey j-b, this just reminds me of the frequent to hell with VLS polls. why cant you abandon VLS and concentrate on VLC? it will help a lot in my features being realised to reality soon

VLC could also have a facility to change only the container insted of transcoading the entire file, in case one wants to change such stuff in videos.(mkv to wmv, etc)
