botar Posted April 5, 2015 Share Posted April 5, 2015 Hi, I read the other posts about this and tried the suggestions. This is a little lenghy but I going to try to help troubleshoot by laying out what the issue is and what I've done. HP/Win7pro /8GB ram/integrated audio (realtek) I've have had VideoPad a few weeks and progress has been slow but steady learning how to do things. At first, I had an out of sync problem and then it just disappeared and the video and audio were matched perfectly. Then it went back to out of sync yesterday and I"ve spent hours trying to remedy it without much luck so hopefully I can get some help fixing it. All I want to do is just record live video of me performing on guitar and make video clips for promotional purposes. I found another thread that suggested lower preview resolution and I tried that to the lowest setting didn't fix it. I cleaned all my temp files everywhere hoping it was a cache issue and that didn't help. did a defrag, no help. I updated my sound drivers and the download and install was fairly extensive. Figured I solved it: figured wrong. OK, so the reason I got this software was because Windows 7 Movie maker is so lame, BUT, to verify if it was a hardware or software issue, I recorded a min of video using Movie Maker and lo and behold it was synced perfectly with the audio. Movie Maker video was not out of sync. I'm hoping it's a VideoPad setting that got changed somewhere but I've been through hours of clicking and reading and searching and I"m stuck. , VideoPad did record videos without this sync issue a few times but either something was changed or corrupted. I am hoping to get some ideas of things to check, or all else fails I guess I can try a reinstall. By the end of a 1 minute video, the audio goes on for about 8 seconds after the video stops. thx for some suggestions Link to comment Share on other sites More sharing options...
botar Posted April 5, 2015 Author Share Posted April 5, 2015 I did try to uninstall and I tried the repair option with no help. Then I uninstalled and reinstalled and activated, no help there either. I reviewed the first 3 videos I made and they are in perfect sync. The sync now is way out of whack, about a 15 second difference at the end of a 45 second clip.

borate Posted April 5, 2015 Share Posted April 5, 2015 FIFTEEN seconds out in only a 45-second span! Something is decidedly amiss... What video format? Which audio format is being recorded? Did you try others, and experiment with different encodings? Is it out of sync only in preview, or in the produced result as well? Link a completed file here if possible, so folks can check it out.

botar Posted April 6, 2015 Author Share Posted April 6, 2015 Hi thx for the reply. The title bar of a video says My Video - 0015.MP4 The earlier ones that I recorded and saved (via export video) became .avi files and played normalliy in media player. I took a recent video that was out of sync and saved it. It became an .avi fiile and when I played it in Windows Media Player it was out of sync like the .mp4 from videopad. I am sending a signal from my mixing board to my sound card. I believe it's just a standard .wav file. As I mentioned, Windows MOvie Maker works normally and when I first started using VideoPad it worked normally. Not sure why it changed to this out of snyc status. About attaching a video file, I didn't have any luck using the "my media" icon to attach a video. It doesn't seem to work. When I hit 'search' it just momentarily flashes some status dots in a small window that disappears and nothing happens One thing I didn't mention that might be related (as I don't remember seeing it when it was recording in sync). I have this message whenever I open videopad "The sound linked to the clip youare playing is still processing. You will not hear sound until procesing finishes. (Displayed in a yellow bar at the bottom of the window, belolw the audio track"" I was able to hear everything anyway, but it was out of sync. The warning has been there for the last few days. Maybe opened VP it about 20 times Now to support what I've been saying about working sometimes and not working some other times, I closed and opened Video Pad again and now the warning bar is not there I recorded a short video and it recorded in sync. I haven't changed anything. It seems to be an intermittent issue. I will post again if it re-occurs Link to comment Share on other sites More sharing options...
botar Posted April 6, 2015 Author Share Posted April 6, 2015 I recorded 5 videos that all worked fine. The only thing that is curious is that the first one I recorded was an .avi file (in title bar of video). the next 4 were Mp4's . I did the same as always, hit the record button and selected 'record video'. This seems strange but I guess it's working so I'm happy to be able to record but I have no idea why this problem just h appens at random. Link to comment Share on other sites More sharing options...
c_major Posted April 6, 2015 Share Posted April 6, 2015 If you replaced a video with the same file name, the old sound cache files could messed up with the new video. Please try restart VideoPad and do not load anything, then select Options->Disk->Clear Unused Cache Files. Best regards. Link to comment Share on other sites More sharing options...
botar Posted April 6, 2015 Author Share Posted April 6, 2015 Thank you very much, I'm glad it was something easy. I had 866 MB of cache. Another question please, Is there any reason why I would want to save the cache and not check the option to "delete on exit" ? I either save or discard a clip or sequence when I close VideoPad.

borate Posted April 6, 2015 Share Posted April 6, 2015 Having files in cache makes for faster loads. Unless you return to the same project frequently, it's probably wise to clear the cache and session's end. Link to comment Share on other sites More sharing options...

botar Posted April 6, 2015 Author Share Posted April 6, 2015 Seems to be out of sync again. I submitted a summary of this issue to tech support. Link to comment Share on other sites More sharing options...
c_major Posted April 7, 2015 Share Posted April 7, 2015 Hi, Are the clips you just recorded (the one appear in the media folder after finish recording) out of sync? If it is a recording issue, then probably something to do with the video camera driver. Could you try update the driver or another camera? I've tried a few cameras available for me and they work fine. Best regards, Link to comment Share on other sites More sharing options...
botar Posted April 7, 2015 Author Share Posted April 7, 2015 Hi, got it in sync again. I noticed that the resolution under Capture Video/devices was at the highest setting (640X480 30.00fps YUB and I tried lowering it and went way down to 175/144. Recored about 6 times opening an closing the program and it seems fine now. I don't see much difference in the quality of the picture but not sure, still have more experimenting to do. Preview resolution was reset to a high setting by one of the reinstalls and I dropped it down a notch for good measure. I'll try to increase the Capture Video /devices settings as high as my hardware will allow it all to stay in sync. thanks again and for you paitience Link to comment Share on other sites More sharing options...
c_major Posted April 7, 2015 Share Posted April 7, 2015 It seems like there was not enough computation power for recording at 640x480 resolution. In theory it could cause out of sync when recording. But that never happen before. 640x480 video frames are in fact quite small for modern hardware. Please check if there are other CPU intensive programs running in the background and close them before recording. Best regards, Link to comment Share on other sites More sharing options...
botar Posted April 7, 2015 Author Share Posted April 7, 2015 Per your suggestion, I checked system resource usage and there isn't much running. This is a recent install of the OS and it runs very clean. have a good A/V program. \Resource usage is very low and taking it a step further, I shut off my A/V (Malwarebytes) and disconnected my router to zero out resource usage from a network connection. I also set preview resolution down to lowest setting,(320) and also selected the lowest setting on the Capture Video/Devices resolution (160 X 120). I cleared the cache manually as well as checked the box to clear on exit When I record, the audio track is immediately off sync. It's almost like it is offset from the git go. I really don't think this is a resource usage issue. My processor is an I3-2100 with 3.1GHz and 8 GB of memory. I again tried Windows Movie Maker and it plays back in sync. I would think that if it were a resource problem than Movie Maker would also be out of snyc. And as I've mentioned, VideoPad did work perfectly a few times, even before I learned about clearing the cache, which made it work but only until the next time I opened the program. I still have 2 weeks to figure it out before the 30 day return is expired. I really need and really like this program but of course I have to be able to use it. It's weird that it's so intermittent and the sync is so far off, but on occasion is perfectly synced. I do have a 64 bit OS. Could this be an issue ? It wouldn't explain the intermittentcy but thought I'd mention it. Why would Movie Maker work and VP not ? I looked at the resources numbers in resource monitor with VP open: VP is using 479. Chrome was listed as 6,000 and system was listed around 15,500. Nothing else was running. Link to comment Share on other sites More sharing options...
c_major Posted April 7, 2015 Share Posted April 7, 2015 Could you please tell me what kind of recording device(video camera) you are using? I'll see if I can get one and replicate the problem. Link to comment Share on other sites More sharing options...
botar Posted April 8, 2015 Author Share Posted April 8, 2015 Hi, I am using a Logitach C170. Not exactly high end but fairly good quality . After getting nowhere again today, I reinstalled the program and it worked perfectly again. Even at the higher resolution settings for preview and device. The only thing I noticed that seemed a tad odd was that in encoder settings, after the fresh install and it working normally, I noticed that the settings were MPEG4 (compressor), and other two settings were 768 average, 1024 max. I would think that these are the default values since it was a fresh install. But when I click the button that says, "restore defaults" , the compressor changes to H264, with a 23 value of quality. I tried recording to see if this would affect the sync. It did. The sync was way off again. So I changed it back to MPEG but it did not correct the out of sync recording as would be logical. Probalby should have left it alone, but I wanted to verify the issue. I just reinstalled and it loaded with MPEG4 as the compressor but it is out of snyc again. Had it for today. Doesn't make sense Link to comment Share on other sites More sharing options...
c_major Posted April 8, 2015 Share Posted April 8, 2015 I've tried switch between the two different codecs. Occasionally I got a few seconds frozen image at the beginning of the video. I'm not sure but it seems to be a choking when the codec starting to work. But after the frozen part the video plays fine and the sound did not out of sync. Have you seen that frozen part? It could be the frozen part was somehow skipped and cause out of sync. Are you using the latest version (v4.00)? Added: When I press the record button, the UI look empty for a few seconds before showing the first frame. Please play attention to that time since it might be as well the duration that you got out of sync. Link to comment Share on other sites More sharing options...
Nationalsolo Posted April 8, 2015 Share Posted April 8, 2015 Hi Just to add my twopennies worth... ..I used to have a similar problem some time back with a much earlier version of VP. I found that HD MPEG4 h.264 video shot with my camera, particularly in the larger formats, always became graually out of synch with the sound, sometimes, as you have experienced by several seconds with quite a short clip. After a lot of messing about I found that if I converted the MPEG4 to MPEG2 format the problem went away. There didn't seem to be any visible difference in the output...in fact the MPEG2 clips seemed clearer with more contrast. Couple of previous posts... http://nch.invisionz...ynch#entry47182 http://nch.invisionzone.com/index.php?/topic/18614-sound-out-of-synch/page__hl__%2Bout+%2Bsynch Just a thought Nat Link to comment Share on other sites More sharing options...
c_major Posted April 8, 2015 Share Posted April 8, 2015 Hi, Please try Debut which is another NCH product dedicate for video recording. It shares some of the underlay components with VideoPad but exposed more options. It may help us identify the problem. Here's the link for the free non-commercial use version: http://www.nchsoftware.com/capture/debutsetup.exe. To recording from a webcam, simply click Device on the tool bar. In Option dialog please try switch the Use original frame timestamps option on and off. See if it makes any different: Best regards, Link to comment Share on other sites More sharing options...
botar Posted April 9, 2015 Author Share Posted April 9, 2015 Hi, I tried to use the Debut software and clicked use demo version. When I clicked on the red record button a pop up box said I had to purchase it. Maybe because it tried it a week ago ? Anyway, just came back from Best Buy and I got a better webcam (Logitech C310) and it seems to have corrected the issue. $$37 was worth getting a clearer picture and hopefully getting the sync issue corrected. Keeping my fingers crossed that that was the problem. thanks again Link to comment Share on other sites More sharing options...
pusmuky Posted April 22, 2015 Share Posted April 22, 2015 Excuseme but i dont speak english, si alguien me entiende y me puede ayudar se lo agradeceré, despues de exportar abro el archivo y no se ve imagen sólo la musica Link to comment Share on other sites More sharing options...
c_major Posted April 22, 2015 Share Posted April 22, 2015 Google Translate (Spanish): if anyone understands me and can help me I would appreciate it, after export open the file and no picture is only music Could you please describe the problem in detail, for example: Which version of VideoPad are you using? Are you getting the problem all the time or just for one project? Have you applied any effect or transition? Which codec have you chosen to export?

botar Posted April 22, 2015 Author Share Posted April 22, 2015 All is still running good after 2 weeks so definitely the old webcam quality.. Nice call on the suggestion. thanks again. Link to comment Share on other sites More sharing options...
