  1. Thank you @borate and @Nationalsolo for your great efforts and help. I'm currently getting the results I want with v7.10 even when exporting at 30fps. This is why I'll stick with that version now. I'm pretty certain now, that from v7.10 to v7.11 there was an ill-advised change in the order that speed change and frame rate are applied during the rendering process. (Hmmm, this is in disagreement with the fact, that borate managed smooth slowmo with v7.30... Anyway, I have a working solution now and am tired of testing around.) Once, I feel the need to upgrade, I'll go with what Nationalsolo suggested. However, that would still be a workaround. It may leave only 144fps from my original 240fps. And it would require an additional rendering step in order to bring down the frame rate from 144fps to 30fps for a reasonable file size of the final video. Thanks again. LeFouu
  2. v7.31 beta w hardware acceleration: smooth slowmo failed v7.31 beta w/o hardware acceleration: smooth slowmo failed v7.00 beta w hardware acceleration: smooth slowmo successful v7.00 beta w/o hardware acceleration: smooth slowmo successful support of my projects done in v7.11 by v7.00: failed ☹️ Any thoughts?
  3. I installed v7.30. Problem remains. @Nationalsolo In v7.30, the frame rate of the preview cannot be changed anymore. Only the replay speed can be altered, while the number of frames remains unchanged.
  4. I agree. What you posted is exactly the type of result I want to get out of VP but don't for whatever reason. I'm going to play with different versions now and see what I'll find out....
  5. @Nationalsolo: right click on preview window --> change preview settings... @borate: Ok, the 60fps-export (your link above) is somewhat smooth, i.e. 8 unique fps. Let me show you, though, what I'm actually expecting, by this little video: https://1drv.ms/v/s!Ahz4HZhUyUj0afw_X-4HJEwI3HA See how much smoother the slowmo is as 12% speed (30 unique fps) and even at 6% speed (still 15 unique fps)? I used to be able to create these type of smooth slomos using VideoPad until about May this year. So it must be possible. But how? Can you guys tell if this is a bug in the current versions of VP? If so, I'd expect many complains from other users. Are older versions available anywhere? Or could it be an issue of my operating system or other installed programs?
  6. Hi Nationalsolo and Borate, please be aware: The orignal file ("6 Peer Hockey oben~2.mp4" included in the zip file) has 240fps. This was the setting of the camera and this value is stated in the properties displayed by windows. And if I replay this file in the VLC media player at 0.12 speed, it looks super smooth. Even at 0.06, there is only very slight jerkyness, which is in agreement with about 15 updates per second. And this is what I want my VP export to look like. If you change the preview settings in VP to 240fps, you will see that the original clip in the bin contains about 240 unique frames, i.e. no copies, one every 4 milliseconds. When we now change the clip speed to 12.5% VP ads 7 copies of every frame. This indeed results in a slow motion and an 8 times longer clip length while maintaining the preview settings of 240fps. Hence, so far everything is fine. Now, if I export, I get the same result as described in my post from yesterday: Jerky with about 4 updates per seconds for 30 fps and half as jerky with about 8 updates per second for 60 fps (this is what Borate did). In conclusion: Even though the the original clip in the bin has 240 fps, which should result in a smooth 12.5%-slowmo (with 30 updates per second), VP exports a jerky result by first reducing the frame rate to the export value and THEN applying the speed change. Performing it the other way around would result in the desired outcome. Is there any way to change the order of these rendering steps? As I stated earlier, I used to be able to export smooth 12.5%-slowmo (with 30 updates per second).
  7. I uploaded a demo project and its export here https://tinyurl.com/y4v6bccp Usually, I don't pay much attention to the quality of the preview. Just now I noticed that, before the end of the caching-progress-bar, the preview is as choppy as the final export. Beyond the end of the progress bar, the preview showed smooth slow motion. Anyway, I hope the uploaded project allows you experts to get an idea of what might be the problem here. I didn't specify my export settings because the problem occurs for any settings.
  8. Thanks guys for your replies and sorry for getting back so late. I didn't realise until now, that my post had actually gone through. I'm glad that it did, though, because I'm still experiencing the same issue. However, I have gained additional insights: 1. The issue is unrelated to any effects as I originally assumed. Just the first time it showed up was when I added effects to an existing slowmo project that until then had exported fine. This means, I'm now always getting choppy slowmo exports even without additional effects applied 2. Original footage was shot at 240 fps. Speed is changed to 12.5%. 3. If I export at 60fps, the result is only half as choppy as 30fps-exports. To me it looks like VP, upon rending/exporting, first sets the frame rate to the desired value and THEN applies the speed change. The correct way would be the other way around. To elaborate: 240fps, speed change: 12.5%, desired result: Video at 1/8 of original speed which should look smooth in a 30fps-export. What I rather think is happening (and is confirmed by playback at reduced speed): 240 fps is reduced to 30fps (60fps, respectively), by eliminating 7 out of 8 frames (3 out of 4). Then speed change is applied resulting in 30/8 fps (60/8fps). Then the export tuns it into 30 (60) fps by adding 7 still frames making the result look choppy because only about 4 (8) frames per second represent changes from the previous frame. Replaying the exports in VLC at reduced speed confirms these assumptions. 4. I uninstalled video pad, deleted related files in the folders C:\ProgramData\NCH Software and C:\Users\(My computer profile)\AppData\Roaming\NCH Software\VideoPad, restarted my computer and then installed v7.11. Same issue. 5. As mentioned under 1.: Things used to work fine. I don't know what caused the choppy slowmotion in May. There might have been a software and/or windows update or windows configuration. Definitely no hardware changes. I'm happy to share whatever files may help to pinpoint the rootcause of this problem. Thanks in advance, LeFouu
  9. VideoPad v7.01 If I take a clip (.mp4, 1280x720, 240fps), set the speed to 30% and export (.mp4, 1280x720, Variable Frame Rate (Max 48fps)), then the result is fine, i.e. as you would expected. If I apply the video effect "Auto Levels" and do everything else exactly as above, then the result is choppy. It looks rather like a video with 10 fps or less. The same happens with the video effect "Temperature" and probably some other effects. Any ideas how this can be resolved?
