  1. I am on a Mac, and VP freezes when I try to go to Preferences -> Disk -> Clear Unused Cache Files. How do I find the cache files via the operating system and remove them that way (unless there is Another way to make VP clear them... it freezes even when turned on without a project and trying to clear cache). Thanks.
  2. Thanks! On a Mac (which is where I am trying to export to the PC FROM), I image I will find a similarly-titled file "EffectTemplate" that I can move over.
  3. I have developed several custom video effects (i.e., saved sequences of existing video effects with particular parameters set) on one computer with VideoPad. How can I install them on another computer with VideoPad? Are they stored in some file that I just need to find, transfer, and connect to the VideoPad in the new computer?
  4. Though putting the resolution of the iMac Pro on its lowest setting still has some jerkiness, there remains an unusable level of jerkiness on feedback to real time actions such as cropping... as you move the mouse to define the crop boundaries, they sit still for a while, then respond to your mouse actions all at once, overshooting what you want. Likewise, other actions such as minimizing a track height, starting or stopping play, and the like all have a delay to them.
  5. What a great suggestion... to scale down the iMac Pro monitor resolution. It helps tremendously. A little experiment... turns out the jerkiness of the image is matched by a jerkiness in the cursor timer, which displays only about 2 sub-second values within each second demarcation of the counter (on the PC, the sub-seconds advance smoothly, as the frames play smoothly). Here is what I found: PC: 1920 x 1024 smooth - continuous subsecond advancement on counter and smooth motion in image MAC: Default - 2560 x 1440 - jerky, 2 subsecond advancements per sec on counter and two frames per sec MAC: Reduced Res: 1280 x 720, 1/2 as wide window - about 1/8 the number of pixels as Default - almost smooth, jerkiness too little and frames too many per second to count MAC: Closest pixel count to PC - 2048 x 1152 - more jerky than Reduced Res above but not as much as Default - usable. Thanks, borate, for all of your help. The example you presented (done with a PC) is exactly what I get (with a PC) - the singer tiles are NOT all in synch, because it is from a Zoom meeting with separate electrical paths for each image - however, in the final product, I can and do fix that (but need the non-jerky resolution to do so!)
  6. Here is a link to a MS OneDrive with a folder 2020-10-12 17-38-2..Diagnostic: https://1drv.ms/f/s!AgsUsCgrY2hLjJVtRP97aeiQfplG0Q There is one video file and one audio file. If you run the video file as a clip on a MAC (iMac Pro, specifically), it is not too bad in jerkiness. If you put it on the timeline and run it as a sequence on a MAC, it is jerky, at less than 2 frames per sec. If you then put the audio file on the audio timeline, mute the audio from the video clip, and try to synchronize the audio file with the video (the audio file starts about 5:32 min:sec into the video), you will see how hard it is to synch, as the video jerks through several syllables at each frame. It works fine on a Windows PC! Anyone able to do this on a Mac? Let me know... I cannot! Thanks!
  7. I downloaded the latest version, which indeed is 8.90. By the way, how do you learn the version number without actually loading it and looking at "About?" I tried turning off hardware acceleration... no difference - still less than 2 frames/sec. Other diagnostics suggest that the preview processing does not use the GPU (where this machine is so much more powerful) that much... the graphic processing does get heavily used in the Export step. So maybe turning it off would not affect Preview that much anyway. The iMac won't accept any driver updates... it reports that all its software is up to date. Still stymied! Thanks for your help so far! Does ANYONE here have experience with preview playback on a Mac? Is it smooth or is it jerky? Even that bit of info would help (as well as size of image, type of Mac, etc.) Thanks!
  8. Thanks! I have VP 8.79, which was the version linked to me about 3 weeks ago by NCH as part of their debugging, so I think it is the most recent. The download file at the link you posted does not have a version number in its title... do you know what version it is? The iMac Pro arrived three weeks ago new from Apple, so likely has most recent video drivers. When I try to do a software update, it tells me its software (including video drivers, I presume) is up to date. I don't have another Mac to try it on... I am just sticking my toe into the Mac world. The hope is that NCH has a Mac to try it on, but so far no answer. I do (and have always had) Hardware Accelerator turned on. Thanks!
  9. I have submitted this problem to NCH Software over 40 days ago, and they have elevated it to their developers, but (despite my paid-for support), they have not yet been even been able to determine whether or not they can reproduce the problem. ([TK-wt7i400001-A12] Pty4 VideoPad TechnicalSupportRequest Mac) Hence, I come again to this forum in hopes that some Einstein, Borate, or other kind soul can tell me what to do, and whether this problem occurs on all Macs, or just on mine. In short, previewing a video clip on my iMac Pro, in either the sequence or the clip previewer, only occurs in very jerky manner, with a frame rate less than two frames per second. My iMac Pro has 18 processors, 64 GB RAM, Radeon Vega 64X GPU. This jerkiness renders VideoPad useless for my basic task of synchronizing video of singers' mouths to their audio... you cannot see just when their lips change shape! The capability is just fine on my HP Pavilion 27-a210, which has only 4 processors, 12 GB RAM, and an on-board GPU from Intel. According to Geekbench 5 scores, my iMac Pro is 2.5 times more powerful than the PC on CPU tasks, and over 10 times more powerful than the PC on "Compute" tasks (which include a lot of graphics processing). Yet its preview is much jerkier. I surmised, and someone here confirmed, that the fact that the pixel density on the iMac Pro was 7.5 times greater than on my PC was contributing to the problem. So I reduced my preview window such that its area was less than 1/7.5 of the area of the preview window on the PC, hence assuring no more pixels were involved in the Mac preview than in the PC preview. I also cleared the cache as suggested. Neither of these helped. In fact, I intermittently got the problem that the iMac could not process .wav or .mp3 audio files... it would just sit "Processing." without conclusion. Has anyone here had a problem with jerky previews on the Mac version of VideoPad (besides me?). Anyone have any idea how to fix this? So far it seems to have stumped the NCH software developers. Is Videopad truly a product for the Mac as sold by NCH, or is it either unsuitable or needs something more? Thanks!
  10. I have had a rather plain vanilla all-in-one PC (3-year-old HP Inspiron with 4 processors & Intel graphics processor - Geekbench 5 CPU single score of 1021, CPU multi score of 3746, Compute score of 5758, 12 GB RAM) and have just gotten a much more powerful iMAC Pro (10 intel W processors w/ Radeon Vega Pro 64X graphic processor and SSD, 32 GB RAM, Geekbench 5 CPU single score of 1126, CPU multiscore of 9488, Compute score of 62856). I have VideoPad version 8.45 for the PC and version 8.66 for the iMac Pro. For the SAME stored VP project, the sequence preview on the PC (after appropriate waiting so that the CPU settles down after completing preview processing), is smooth... I can easily synch singer mouth movement with a separate audio track. On the MAC for the same VP project, the sequence preview is jerky... maybe 1 to 2 frames per second, confounding the synching of lips in the video with music on the audio. Investigating this, I found that for the same VP project, the PC exports an .mp4 video file that is only 1/8 the size of the MAC mp4 file... with same resolution and frame rate, both at "default quality and resolution" settings and same H264 encoder. Why??? More observations on my problem above... I read that when VP removed the option of selecting preview resolution, it instead chooses something based on the resolution of the monitor being used. My PC monitor is 1920 x 1024; my MAC monitor is 5120 x 2880 pixels, a total of 7-1/2 times as many pixels. Could it be that the 2-1/2 speedup on CPU processing of my MAC is being overwhelmed by the 7-1/2 times more pixels? How do I get around this? Is there a way to reduce display resolution that VP sees? Also, perhaps the greater resolution of the MAC causes VP to treat my 1,920 x 1,024 video as is, no resampling, while the lesser powerful PC with fewer display pixels triggers some kind of down sampling in VP, hence leading both to better preview behavior and smaller exported file sizes. How can I set or control this possible resampling or lack of resampling? Finally, I notice my MAC has a slightly higher rev number of VP than my PC (8.66 vs 8.45). Where do I find old versions of VP so I can go to an older version (maybe even one of the versions so old that I can control sequence preview resolution and frame rate... how long ago or what rev number were those still user-adjustable?) Thanks!
