kristiansen Posted August 26, 2019 Share Posted August 26, 2019 Have some observed that Pan and zoom function with photo working erratically in spurts in version 7.25 I think the problem occurs around version 7.05 Here is an example created with version 7.25. https://youtu.be/8Y5lFqCOw5E And here the same example created with version 7.02 it's okay https://youtu.be/otrWk-IAoeo Link to comment Share on other sites More sharing options...
borate Posted August 26, 2019 Share Posted August 26, 2019 Ran a portion of your 7.02 output through 7.25 Pan and Zoom once again. Resolution is down, but the jerkiness isn't evident. Tests with other images - of various resolutions and aspects - showed what may be very subtle differences between 7.25 and 7.02. Hard to tell. What are your PC's specs?

Nationalsolo Posted August 26, 2019 Share Posted August 26, 2019 Hi I can see the "jerks" in your UT clip. But have they originated from VP? I have tested a 1920 x 1080 jpg image here with VP 7.25 both as a 10 seconds clip and then a 20 second clip. Previewing the result of both tests, Pan and Zoom from one area to another in preview showed no jerkiness and exporting each as an mp4 H264 1920 x 1080 clip (45 fps) at HQ showed a perfectly smooth pan and zoom (played in VLC) I then repeated these tests with just a big zoom into the image centre. (As big as it would go.) using the same export settings. Played in VLC there was a perfectly smooth zoom into the image centre for 10 (and 20) seconds with no sign of any jerks or stoppages. Was this defect seen in preview or only in the exported clip. I'm just running the same test with an 15 second 1280 x 720 mp4 clip with sound zoomed in at 16:9 to the centre (maximum zoom)........ My slow Vista PC did not manage to develop the green bar although I left it for some time and preview was interrupted repeatedly by "Generating Preview" messages, nevertheless I exported the timeline as above.. Again this was a perfectly smooth zoom with no trace of jerkiness. Perhaps it originates within the export to Utube (if it's not seen in VP or an export to your PC) Nat Link to comment Share on other sites More sharing options...

P_and_Zoom.mp4 My specs: Intel corei5-7300HQ CPU 2.50GHz 8.0GB RAM I agree that it looks good enough here, but I don't think the resolution is adequate. The problem was created on my PC with version 7.25. But everything is ok with version 7.02, with the same project file. It seemed like uploading to youtube also went faster with 7.02. Is the photo resolution lower by 7.02? I use a full jpg photo approx. 10Mbyte Link to comment Share on other sites More sharing options...
borate Posted August 26, 2019 Share Posted August 26, 2019 The above test was just a screen grab. Upload a few of your source photos and link them here. Someone will check them out with P&Z. Did you create the effect in 7.25 ... or simply load a project that had been made in 7.02? If that was the case, try recreating the effect in 7.25.

kristiansen Posted August 26, 2019 Author Share Posted August 26, 2019 I made the project in 7.25 and discovered the problem, then I try 7.02 and the same project, and no problems. Link to comment Share on other sites More sharing options...

borate Posted August 27, 2019 Share Posted August 27, 2019 Exported your project at the default settings, which took some time to create a nearly 1GB Mp4 file. Looked about as good as expected, and nothing like your demo above. Some jerkiness on the video, but that's seems more attributable to camera shake than VP P&Z. Have you tried viewing the project in another player, like MPC-HC? Link to comment Share on other sites More sharing options...
kristiansen Posted August 27, 2019 Author Share Posted August 27, 2019 I tried exporting an mp4 file to my own computer, and then played it in Windows Media player, it seems to work.😊 Is now in the process of uploading to Youtube, it takes loooong time. Oh no Video unavailable, I'm tired. Link to comment Share on other sites More sharing options...
kristiansen Posted August 27, 2019 Author Share Posted August 27, 2019 Ok after a while, the video was there, and it works.😊 https://youtu.be/9hscd7GC35A There is obviously a difference between uploading via the export/youtube-button compared to exporting a video (mp4) to desktop. and then use YouTubes uploader Link to comment Share on other sites More sharing options...
borate Posted August 27, 2019 Share Posted August 27, 2019 YouTube has a number of formats that it will accept. Try a few. Export to that file type, then use their uploader to see if results improve. https://smallbusiness.chron.com/video-formats-youtube-accept-79772.html Link to comment Share on other sites More sharing options...
kristiansen Posted August 27, 2019 Author Share Posted August 27, 2019 Oh I think you misunderstand me, I have uploaded a mp4 file with YouTube's uploader, and it works 😊. https://youtu.be/9hscd7GC35A but something goes wrong when I use export/youtube button in VP.

borate Posted August 27, 2019 Share Posted August 27, 2019 Specifically, what goes wrong when you attempt to use VP's direct YouTube uploader? Error messages? Link to comment Share on other sites More sharing options...
kristiansen Posted August 28, 2019 Author Share Posted August 28, 2019 The problem, the jerky rendering, no error message. Link to comment Share on other sites More sharing options...
Jack11223344 Posted August 28, 2019 Share Posted August 28, 2019 Bug is confirmed. Will be fixed in the next release. Work around is, when upload to youtube directly in vidoepad, in the setting dialog, choose 60 fps instead of 30. Thanks Jack Link to comment Share on other sites More sharing options...
Jim Tobias Posted January 3, 2020 Share Posted January 3, 2020 I'm experiencing jerky P&Z with version 7.51 when making an mp4 for direct viewing, or exported to YouTube via VP directly. I'm P&Z'ing still images, which are smooth in clip preview. See example at 1:14+, https://www.youtube.com/watch?v=1W9AIuB0VPs Link to comment Share on other sites More sharing options...
