Sequencing question/problem


Guest guest
 Share

Recommended Posts

I am working on a new squence and just discovered that you don't have the play the entire song every time. I am sequencing/editing and playing just the visible portion of the song until i get it like I want it and then scrolling on to another section. This has been much easier and I don't get nearly as tired of the song.



Here is the problem/question. when I play the segment, it is squenced perfectly (or as close as my abilites allow) but when I play the entire squence it appears out of synch. then I go back to that section and play the visible screen at it is fine.



Is this something that happens regularly or am I most likely doing something wrong?



I am new to this so it is very possible that I am missing something or omitting a step in the process.

I haven't tested the sequence on my lights, just the animation window.

and playing the full sequence, it doesn't play all the way to the end. I have a big finish that plays perfectly on viible screen but the song cuts short when playing full sequence.

Hey Andy,

I think you are seeing what some of use see...as you play the whole sequence in the editor, the vertical bar hangs for a few seconds then it catches up. This will probably be fixed in LORII. If/When you have lights hooked up and your are actually running a show, the sequence you built screen by screen will run like you designed it.

I believe that's because the length of your audio file and the length of your lighting sequence don't match. I don't recall the solution (you might find it in another LOR forum topic) ... but that's the area I'd been looking to modify.

If the time is off by that much then I would guess the file is variable bit rate. You should check that out and if so convert it to fixed bit rate.

i'm gonna take a complete stab in the dark here, as i have NO experience with LOR (yet)... but i'm assuming you're playing an mp3? If Dan says it might be caused from a variable bit rate file, then why don't you convert it to wav and re-encode it using a set bit rate (160, 192, 256..etc)

I'm still new at this and learning so much every day. But I'm willing to take a stab here.

Looking at the length of music you are playing, let's say 4:05 minutes to play the whole song. Is the sequence for the song/music as least 4:05 minutes?

My first time messing with sequencing was oops, my sequencing display was shorter than the full length of the music mapped to it.

I know that sounds too simple to goof up but I admit, I did it.

Anyway, it's something to look at.

UPDATE!

Andy sent me the MP3 and I must say it was way way way off in the Sequence Editor...Not Andy's work but the Sequence Editor's Visible Screen vs Entire Sequence. I re-encoded it without making any changes, same bit rate and it because 1 meg larger so my guess is that it was variable bit rate. The strange thing was the play time difference. When I hover the mouse over an MP3 file it gives a play time. That play time changed by 20 seconds with the re-encoded file.

I think that it will work OK now BUT the work Andy put into the sequence is pretty lost. Sorry:(

Maybe i should give more detail. I downloaded a free program to convert my audio files to MP3 because for some reason my software doesn't recognize an audio file from a CD. Like if I rip a CD using Windows Media player, I can't open that song using LOR, it doesn't recognize it or show it in the window so that I can open it when making a new squence. If I convert it to MP3, the squencing editor recognizes it just fine. I better double check and see if there is a setting on the conversion program for varible or fixed bit rate.

Andy, here's what I do. It may not be the easiest but it works for me. I rip the cd with windows media player then find the folder with the music and minimize it. The I open the sequence editor, click on new file --> new musical sequence. When the window comes up with "Open Audio File", I click on the up one level tab. The I open the "Audio" file foe LOR. Bring your music folder back up and copy and paste the music to the LOR audio file. That puts the music where you want it. When you go back to work on the sequences, in the open audio file, type *wma in the file name box and the wma files will show.

Dan,

How about another feature request. I think you can detect if you've got a VBR or CBR audio file programtically using the media player API. I'd suggest checking that when the audio file is picked or associated with a sequence. If it is variable rate, either don't let them use it or give a really big warning.

OK, I did my homework on a particular situation before asking a question. From reading the fix above (back in late December) and my situation which is very simular, especially on longer sequences. The longer the song plays, the longer the delay of animation versus the music, BUT if I play in "visible screen", it seems to be in sync. Since I took down my test lights, I can't test it right at the moment. Will there actually be a delay in the lights? Dan, what did you do to re-encode it and what was it that was re-encoded? Also, does the bit rate make a difference? How can I change it?

Andy,

You can get LOR to use a windows media WMA file. It's just not preset to recognize that there are files of that type to choose from. Dan touched on this in another thread at an earlier time. I looked and couldn't find that thread, so I'll just tell you how I do it. But before I do I'll tell you something else he wrote that helped me immensely. LOR editor seems to work best with WAV files. I had two MP3 files that wouldn't sync at all. I converted them and they work fine now. OK now for the WMA files. Click on the filename for the WMA you want to use. Then click it again and it will go to the filename edit mode and highlight the entire filename. Now just hit ctrl and C at the same time to copy the filename into the windows clipboard. Now go start to create a new Musical Sequence and paste the filename into the dialog using ctrl and V at the same time(even though you can't see it in the dialog) it will then be displayed below that filename including the .wma extension. Click that filename and you can continue on as if it were any of the other file types. I hope this makes sense.

Let me try this again, Dan? any suggestions?
