Vegas 18 detects wrong source video frame rate
I just came across this problem today, and have been searching the forum. I was trying to edit a short clip shot on my iPhone using the 4K 24fps setting, my project is 23.976 and after rendering the project with a frame rate as the project the video was all jacked up. This is when I noticed that the source media properties frame rate was 25fps PAL. I was able to render it some what acceptable video after disabling the resampling but still not completely satisfied about this issue. After reading several post and found out about the VFR issue. I tried hand break but when I set it to constant rate of 23.976, same problem, and Mediainfo also still states that it is VFR for the new file. When I set hand break to 24 constant it then shows it as 24fps Film in Vegas. My question is will this cause an audio sync problem when rendering longer clips? Plus these files are giant compared to the original. Also why does Vegas default to 25fps PAL for VFR files vs. defaulting to 24 Film or even 23.9? Its not like the variable rate ever goes higher than 24fps after the hand break conversion, so why does Vegas interpret it to be 25fpsPAL?

audio fx multiplying and distorting / destroying waveform event clip
Thanks Nick and Friar for help and testing. I would provide a sample WAV but not sure about how to share it. The forum upload will only allow mp3 attachments. I still had problems even with the preset "Fletcher-Munson curve" with my file. Although I have to say Nick, that I didn't see my problem with the organfinale.wav either. I noticed that it is 44k Hz instead of 48k. Small difference but perhaps enough that my system does not take issues with it. Using Vegas I did a re-render of the file from Audition, and selected the same settings from the wav selection of the 48k Hz and 32 bit float, and have the same problem with the Vegas rendered file as the Audition file, i.e. around the third loop being very distorted and clipping. I also found too like you said Friar, that if I just minimize Vegas window and then go back the file is momentarily normal until about the third loop. Again using Vegas to re-render the file from Audition only this time selected 16 bit WAV, and this render setting doesn't have any problems using the same FX (using Track EQ with increasing the 3rd frequency band by a little bit). I also used Audition to open the 32bit float file, then "Save As" this time with a setting of 24 bit fixed integer and put this file on the timeline and it plays with the FX just fine. Also did another save as with Audition this time with 44k Hz 32 bit float, no problems with the FX. I also again tried the FX on the track vs the event and it plays the 32 bit float file/s with the FX without any problems either. So it appears that 48k Hz 32 bit float WAV files at the event level FX's are not compatible. Anyway not with my system. Very odd.

audio fx multiplying and distorting / destroying waveform event clip
Thanks for the suggestion/help... I also wonder if it was somehow an odd thing. Not embedded projects. If I start a new project, add a .wav file then add Track EQ to the event, not the track, select the event, turn on the loop, hit play, add an increase to one of the frequency bands and then just let it loop, before long the event is screeching like a poltergeist and very loud. Ok, in writing, I had a thought, I said a .wav so I decided to try a mp3 file different source, no problem, now I just render the problem event as a mp3 and put on the time line no problem with the new file, still have a problem with the audio event. The attribute of the file is 48K Hz with 32 bit (IEEE Float). The file is a dialogue replacement dub that I had used Adobe Audition to fit the timing to the original video clip and when I save it, it saved to the above attributes. So to double check, and just make sure that it was the wav file format, I added the original video clip (.MTS) to the time line and added the same Track EQ to the audio event with similar adjustments and well, no problems. Not sure what to think. My fist thought was that I perhaps had some setting change by mistake, but now it appears to be file type specific coming from Audition. Any guess as to why a wav file with 32 bit float cause problems like this. I guess I can change all of the clips to mp3's, but what a pain.

Paste Event Attributes bug - VP13 & VP12 - Fixed in VP14
Last week using VP13, I was doing a bunch of color correcting for an hour long program and having crashes one after another until I realized that it had something to do with when I left the FX dialog box open. Now I see it is not just my system. I however do like how that it deletes the old FX's vs. stacking the new on top of the old with the pasting event FX. Never liked having to go in and delete the old manually every time when I was pasting over many events.

rendering for dvd ?
For my recent HD 24 progressive frames project to SD render, I used a slightly different approach; but for my approach you need a large hdd with plenty of room. I did the same as PeterDuke for the audio. I didn’t like the results I was getting when I rendered directly from my HD project to the widescreen DVD main concept template, soft/blurry and artifacts, so I made a custom AVI intermediate file by rendering to an uncompressed AVI, with these settings: starting with Sony YUV 1080 24p, and chaged it to a custom frame size of square pixel aspect ratio, 854X480 at 23.976 fps, no audio. Then I put the AVI file back into my timeline to verify that the audio still was in sync (it was) and then changed the settings in the project properties for the default project template to NTSC DV 24p Widescreen (720x480, 23.976 fps). (saved as a different project name so I didn’t mess up my HD project) Now render using the default DVD NTSC DV 24p widescreen. It will correct the pixel aspect ratio to the needed 1.2121(NTSC DV Widescreen) and put in the necessary 3:2 pull down too. Put this render into DVD architect along with your audio as PeterDuke has stated. The results were considerably clearer. I think that the pixel aspect ratio from square to not square plus losing resolution is asking for too much to be done all at once. One other thing is that I was working with only progressive source files, there are other issues if you have interlaced that I did not have to worry about.

CPU question
Wow! Just changed a couple of settings and instead of taking five and half hours to render, it only took one hour and 20 minutes. I changed project properties from 32 bit video color to 8 bit and then changed in preference the default 16 threads to 10 (12 available) and kept GPU enabled. Also eliminated some track FX, in particular broadcast color that was causing a problem with my blacks not being black (may or may not have had much impact). The CPU jump up to max usage around 92 to 94%. It would only drop down when I had motion graphics that are already at 24p (14%) or in the areas that I had resample disabled (about 40%). Thanks videoITguy for the tips and where to look.

CPU question
Yes, I'm using the 64bit install. I have not instaled any plugins other than what comes with Vegas, so I'm not sure what versions they are. I unistalled the newblue titler. I breifly had the 32 bit VP-11 because I had read that it didn't crash as much, but still had crashes and so I unistalled it, because of the limit in memory usage. I am using 32bit color space vs 8 bit in my project.

HD 1920x1080/60P (not 60i) to a SD DVD resolution?
My results when I tried the 30p in a 60i render and then looked at the results in AE, it says that it is interlaced and I could see interlaced artifacts (staircase look on diagonal lines). With resample off, I tried 0.5 vs. 1 undersample rate, but it did not make much difference concerning being interlaced, nor did I see a difference when played on my computer, it had noise on the diagonal lines. I have read that viewed via DVD or BD player it will appear as 30p but I think that it is still interlaced. Bob (frass) said this in another thread: http://www.sonycreativesoftware.com/Forums/ShowMessage.asp?Forum=4&MessageID=718970 “I'm assuming you'll deliver 30 frames per second, either as 30p or 60i and in both cases for a 180degree shutter, the shutter speed should be 1/60. Vegas should do a perfect job of converting 60p to 60i, it simply converts each frame to a field” To me that means that it will take a frame and convert into a field i.e. half of the information/odd lines of the frame and the next field would be the rest of the information/even lines, and then when viewed from the DVD player they would be combined back together to make the whole frame. In a sense it is 30p but still interlaced all the same, that is my thinking so if is wrong, oh well, I will just accept it as that, thanks anyway. I also did a test with a custom render at actual 30p and it is sharper than the 60i played back on my computer and in AE no artifacts. While I was at it I also did a test a render at 24p both undersample rate at 0.4 and 1.0. The both the 24p with the two different undersample settings look pretty much the same when played and when looking at frame per frame in AE, definitely a different cadence than 30p of course. From this article I think that possibly the undersampling properties switch has more of an FX effect if you are using a different rendered frame rate/project properties frame rate from the undersample setting. http://www.sonycreativesoftware.com/creating_a_stutter_video_effect I also read from another forum for the Panasonic tm700/900; that it eliminated artifacts seen on his burned BD when he did not use the 0.5 undersample rate setting when going from progressive to interlaced i.e. 60p to 30p to 60i; therefore when going to interlace it may have more importance. I’m not sure. After all of this, I still think that a 24p BD is the way to go for this project. The clip that I did my test at 24p was very acceptable. The clip with resample off compared to smart resample on is clearer for the 24p render. I will try some additional testing in the areas that I saw ghosting on other clips in the project. The test clip that I was using did not have any ghosting in these last tests. I originally chose it because that it is where the down res to DVD results are really bad of which I haven’t resolved yet. Mabye the 60p to 30p to SD 60i would be better for the DVD results.

HD 1920x1080/60P (not 60i) to a SD DVD resolution?
Well I did a test by using the same MTS file in Vegas to an AVI 1920x1080p60 then to AE to change the frame rate to 24p did not work out. Worked fine for the original MTS file but the AVI file from Vegas looked pretty bad after being changed to 24p. Not sure why, but I’m glad I only did an 8 second clip. It is looking like this is just not going to happen and I will just have to accept what it is. It’s too bad to. Have great looking 60p footage and not being able to put it on a BD without it being mucked up a bit and nothing that I have tried looks any better and actually a bit worse than just letting Vegas do its own thing by rendering it to 24p and blending the fields. 24p cadence wasn’t so much the goal as was keeping it progressive without the occasional ghosts. 30p in the timeline then render to 60i I think still ends up as interlaced as far as I know and I just did not want interlaced, but I will give it a try.

HD 1920x1080/60P (not 60i) to a SD DVD resolution?
Concerning going from 60p to 24p from what I have read, is that it is not straight forward and not recommended because of the mixed and unpredictable/undesirable results. That being said however, I have what footage that I have, so this is what I’m thinking of doing and wanted to get your feedback. Set the time line as 60p, change the 30p files (not that many) to 60p, change my motion graphics to 60p and then render project out to an AVI file at 60p and then put into After Effects and use Andrew Kramer’s preset FPS Converter to change it all to 24p. I did this with a small original 60p MTS clip in AE (not an AVI file) and the results were clear with very smooth motion and no ghosting. For rendering to an AVI file what video format would you recommend, i.e. Sony YUV vs. Lagarith Lossless for example? Settings? With an AVI file at 24p from AE I then would put it back in the Vegas pro project and render out for a BD in DVDA and also try to do the down res for a DVD; any other thoughts or suggestions? Should I think about going to a different file type than AVI to take to AE? AVC? MXF? I looked at the Genarts speedo and tried it, but the free trial period is over and it put hundreds of watermarks all over the place when it was rendered that made it impossible to watch and to make any determination of what the results were like. Even if the results were good I did not see a way to buy just the speedo function. If I can use what I already have and save my money that that’s the way to go. Bob; thanks for the suggestion though.

HD 1920x1080/60P (not 60i) to a SD DVD resolution?
Again thank you for your input, I’m still here and haven’t vanished as often happens with OP’s. I’m still reading all of the threads that musicvid has pointed out and trying to digest the information. One thing that makes me wonder and I had read parts of those post before I decided to post my questions, was that the threads were about 60i not 60p, but I’ll hold off on my questions about that until I have finished with my reading assignments. I have a question about Bob’s (frass) in having all 24p material changed in batch render. I see an advantage of all video being 24p and if using a third party software that changes rates and gives proper emulation 24p like film very well, would be even more desirable. Would "disable resample" and then converting the entire project to an AVI file at 24p and then resize be at all a comparable process? (All be it not possibly as good as the process suggested) I wanted to ask the question in case it has already been tried but if not I will give some small test a go after I do some more reading.

HD 1920x1080/60P (not 60i) to a SD DVD resolution?
I’m still really struggling with how to get my project to a DVD resolution and have it visually comparable to my previous SD projects. Pilsburypie, I’m not sure I understand the 0.5 under sample, the only place that I know how to set under sampling is on each clip. I have tried various settings on a clip and rendered that clip, but didn’t see much to think that it was the answer to the problem, so I’m not sure I know exactly what the setting that you used, and in PAL land vs. NTSC land it makes it a little harder to translate what you were saying to do because there are 24p and 29i options. In my actual project there are over a thousand files and the MTS clips would easily be over 800 or even more considering a file can be used for multiple clips, so if I need to change each clip I think I would end up pulling what hair I have left out. Is there a way to do multiple clips settings for under sampling at once without copying and pasting clip attributes to each clip, and however would mess up color corrections, video fx, etc.? I still would like to know if there are any other approaches and the specifics on how to take 1920x1080p60 clips to SD resolution and if possible have it look similar to footage that had been shot using SD equipment? What was the process? Ideally it would be project wide in process vs. individual clips. Thanks for the responses and I understand that there are possibly better frame rates other than 24p for a BD, but let’s just say that for instance a project is going to use the source files listed above and they are going to be authored into a 24p BD project. Would there be any settings different from the defaults for rendering to MEPG-2 in Vegas Pro that should be considered in a technical approach other than frame rates to optimize the results?

HD 1920x1080/60P (not 60i) to a SD DVD resolution?
Thanks for the suggestions and gives me some ideas to think about for doing the BD differently. I just watched a good portion of my Blu-Ray version and for the most part the 24fps looks fine to me. It does have a soft feel to it but is pleasant (soft more on the motion side then the resolution), probably because as pointed out only 40% of the frames are being used. There are only a couple of places that the motion is fast enough that I could see what looked like ghosts trailing but really had to look hard for it and perhaps going to 30fps using 50% of the frames would change that and sharpen the resolution some but then again maybe not. I really like the areas that I have slowed the video down on some clips for a nice artistic emphasis look and that would still be there in a 30p project, not so sure about 720p60. I think that a 24p BD compliant format is the way that I should take the BD but just wanted to understand if I should have my settings different than the defaults. Would having the project being a 30p help the DVD output? The DVD is very blurry… lots of jagged lines etc.

I have the same problem with Pro 9 64 bit. SCS customer support said that I should uninstall it and reinstall. I did but it didn't fix the problem. The knowledge base says to fix help is to uninstall and reinstall all of your SCS software... sounded to me a bit extreme... The question is; is this truly the only way to fix it?

Thank you all for your input. In a long round about way, my original question about levels has been answered. I don’t know where I got the impression that everything should peak at 0 db but obviously that was a mistake. To borrow a word from another web site that I read today is that I basically “squashed” the dynamic range. It’s something that just isn’t cover in instruction manual for “So you want to be an editor by the seat of your pants”. I found some more post about this topic at DVi forum that’s pretty informative too. http://www.dvinfo.net//conf/all-things-audio/119644-levels-post.html http://www.dvinfo.net/conf/all-things-audio/73903-eqing-video-film.html Looks like I need to redo everything.

Thanks newhope. I have been wondering about that from the start, and I agree it doesn't seem right about what I have to do with the dialnorm. It does almost seem like watching an hour long commercial. LOL Just kidding it's not that bad, but close. You put this condition in there that leads me to my next question. "(assuming it has dialogue and not just music based)” My project is probably about 90% music, 9% dialogue and 1% FX' like explosions, etc... If the dialog should be -24db to -10 db what should the music levels range be? Another question is. If the source is already compressed, can it be decompressed? Thanks,

I would like to confirm this limitation based on what I’m experiencing. For a DVD, I can only use AC3 5.1 or AC3 stereo at bit rate of 448 Kbps or 192 Kbps respectively and not anything out side of that like 3.1 with a lower than 448 bit rate without it being re-rendered for DVDA pro 5?

Wow, I didn't think that it was going to end up being such a debate. Anyway… I have been trying many things. Burned up ten DVD’s or so and this is where I am. Not 100% happy but... Using AC3 Studio did not make any difference from Pro, actually it was worse. DRC set to none did not make any difference ether. What I have been reading is that it is a Meta tag for the user to match the program to their environment, i.e. if it is midnight they could put on the DRC so that the explosions doesn't wake everybody up and if they are on an jet liner they could use it so they could hear the crickets chirp during the quite part as well as hear the explosion all at the same volume level. I think the DRC depends on how you have your equipment set up; determines if it is used or not. I just don’t know but it doesn’t seem to make much difference on my project though. Moving on... The only thing that has helped is to put the DialNorm to -15db moved the LEF tracks down -6dbs and try to adjust the timeline items if any areas sounds loud after it is burned by moving the peak for those areas away from 0db to more like -3 dbs . Like I said it's not perfect but at least my windows are not blown out from going from a commercial DVD to a burned DVD. It doesn't seem right to do it that way. Maybe my source audio is over compressed to begin with, or the logic of having everything up to 0 db isn’t the best thing to… particularly if the source material is overly compressed to begin with. I’ll keep trying different things out but I’m running out of steam…

I just played a commercial dvd in my computer system but I'm not able to compare apples to apples though for Vegas monitoring. My PowerDVD player only allows me to use SPDIF and my Vegas uses the six channel input to my reciever. The volume was equal comparing the Vegas with PowerDVD playing Kelly's Heroes and my timeline. All though not the same path of getting there. When I tried changing the settings for PowerDVD, it didn't let me and wanted me to buy the upgade. So to compare apples to apples I played ing my dvd using PwrDVD and it was extremely loud on my computer system. I didn't go past my leader it was so loud.

I checked all of my pan types and all except one is balanced 0 db center. The other one is balanced -3 db center for a P51 fly over. Has anyone used the film type pan. I tried it but it kind of muted everything, and I didn't like how it put everything into the center speaker, music specifically. From my understanding of DRC it is a meta tag that a user could impliment on their own system. Perhaps I'm wrong on that but anyway it proably is not need in my project. I didn't change any of the setting when I rendered it so it would have been all of the defaults. Question on the meter levels. On my project I have a leader prior to the movie with my logo. The music is loud on this too. I would think that if it was only music and the dialnorm is set to -27db that it wouldn't be.

Thank you for all of the replies. As this is my first 5.1 project it is probably a combination of all that has been said. I'm going to go over my timeline again. There is one thing that seems to be a contradition in what is being said, and that is should all of my levels be at 0db vs having dialog at -15db. When I was doing my editing I was under the impressiong that it should all be at 0, but after hearing the actrual results on my HT and reading more about it I was starting to think that there should be a difference between the dialog say at -15db and the explosion at 0db. and the music somewhere inbetween. Can all the levels be at 0db and still have a difference in how loud it will be in the final product?
