serafin Posted June 5, 2016 Share Posted June 5, 2016 Hello, having used videopad V2.20 for quite a time I recently wanted to update to the newes version to be able to have more than one videotrack. I installed the actual version 4.42 and encountered a serious problem: Every time I press play in the sequence preview (or move the play cursor while playing) there is a delay of about 2 seconds with video frozen and no sound audible (although the peak meter displays), after which the video and audio play correctly in sync and smoothly. The project is small, just one MOV-movie of about 3 minutes duration, no effects, no other video or audio track. My computer runs on a Intel Core2 Quad cpu with 2.4 GHz and 3GB RAM and there is no noticeable cpu load when playing the video in the editor. I got the strong suspicion that the problem has to do with the Windows XP operating system where I installed Videopad. With Win XP only DirectX9 can be installed, maybe that ist the cause of the delay. I installed the same version of Videopad on another computer (weaker hardware) with Windows 7 as operating system and everything runs smoothely. Do you have any idea what might cause the preview delay on Win XP systems and maybe a clue how this can be avoided? Thanks in advance Sincerely Serafin Link to comment Share on other sites More sharing options...
c_major Posted June 5, 2016 Share Posted June 5, 2016 We've done some work on preview performance since v4.44. Please try the latest version(4.45). Also please make sure your XP have SP1 or later installed. Link to comment Share on other sites More sharing options...
serafin Posted June 6, 2016 Author Share Posted June 6, 2016 Hello Einstein, thank you for your quick reply. When I download and install the latest version from your web page, it still displays "Version 4.42" on the startup- and info screen. Where can I get the actual latest version 4.45? I got Windows XP with service pack 3 installed. I was able to narrow the issue down some more: The 2 seconds freezing whenever I press play in the editor (or move the play cursor while playing) does even occur with pure audio files: When I load a mp3 audio file into the editor, drag it to the timeline and try to start it by pressing play, there is no sound for about 2 seconds although the peak meter displays audio playing. Considering the fact that everything (video too) is playing smoothly after the initial 2 second freezing this seems to be more of a general problem of videopad with windows xp, not so much a performance issue of the codec. One noticeable difference between videopad 2 (which doesn't have that issue) and the latest version is the ffmpeg19 folder along with the ffmpeg10 folder. Videopad 2 has only the ffmepg10 folder. Any other suggestions? Thanks for you efforts so far Yours Serafin Link to comment Share on other sites More sharing options...

serafin Posted June 6, 2016 Author Share Posted June 6, 2016 Hi Einstein, thanks, I'll try that. Yours Serafin Link to comment Share on other sites More sharing options...
serafin Posted June 6, 2016 Author Share Posted June 6, 2016 Hello Einstein, I tried the 4.45 version. Sorry, same effect. Odd thing is that the freezing doesn't happen every time I start the preview or move the play cursor while playing, just most of the time. About one in five times the preview starts immediately and everything plays fine. But most of the time there is the 2 second freeze before the video starts playing and the sound is audible. Do you have any recent experiences with vidoepad on windows xp operating systems? Are there any config settings for vidoepad I could try to change?

c_major Posted June 6, 2016 Share Posted June 6, 2016 Hi, Thanks for your effort to help us clarify the issue. From what you've described, it sounds like an issue with the sound player. When playback for preview, VideoPad sync video to audio. So if audio was delayed, the video will delay too. This should have no effect on the final export result. We have XP systems here but could not reproduce your issue. My best bet is to check your sound card driver make sure it's up to date.

serafin Posted June 7, 2016 Author Share Posted June 7, 2016 Hello Einstein, thanks for your suggestion. I checked the sound driver, seems to be up to date (Mainboard: MSI P6N SLI Platinum with realtek onboard audio chip, Driver Version: 5.10.0000.6849). Following your hint I tried with a video alone, without audio. I opened a 3 minutes MOV video, dragged it to the sequence, uncoupled the audio track and deleted it. Still the video freezes most of the time when playing back from the sequence or moving the play cursor while playing. Maybe another hint: I do have several audio editors installed on the same windows xp system without any lagging or freezing. And I used to play some quite hardware-intensive games (like the Witcher) on that system, also without video or audio problems.

borate Posted June 7, 2016 Share Posted June 7, 2016 If you haven't done so already, upgrade to this NVidia video driver. It is appropriate for both 32- and 64-bit systems and may affect the behavior you are seeing. If problems arise, roll back to the prior driver via CONTROL PANEL|DEVICE MGR|VIDEO ADAPTERS|<your adapter name>|DRIVERS tab. Link to comment Share on other sites More sharing options...
c_major Posted June 8, 2016 Share Posted June 8, 2016 When I was testing on XP, I did noticed the playback cursor sometimes jumps back about 1.5 seconds when start playing. The video will wait until the playback cursor moves back to start position. This is an known XP specified DirectSound issue. Unfortunately it's a system inherent issue and we can't do much about it. VideoPad activates sound player even when there is no audio to play. That's because the video preview playback is driven by the sound player to get A/V exactly sync.

Best Regards, Hello Einstein, that seems to be exactly the issue I'm encountering. But I never had those problems with videopad version 2 on windows xp. Could you be a bit more specific about "sometimes jumps back"? I think there has to be a reason why this happens in some circumstances under windows xp and in others doesn't happen. So it seems there is no known solution to this issue. I could provide a procmon log (windows sys internals) with all file and registry accesses during the 2 seconds between pressing play and the video actually starting to play, if this could be of any help.
