thefsm93 Posted August 7, 2017 Share Posted August 7, 2017 Hello! I'm new to the forum and new to video editing. I am a huge fan of VideoPad and I bought the professional version of the software. That being said I keep running into an issue with the software where the preview seems to lag even after it has been played before. I have increased the video cache to 20GB and it still runs into this issue. Looking at my computer specs I wouldn't think this would be a problem, but maybe someone here can correct me: I7-6800K (Clocked at 4.0GHZ) AMD Fury-X 4GB Graphics Card 32GB 2133 DDR4 Memory 256GB Samsung 840 Pro SSD (boot drive) 2x Intel 750 400GB PCI-E NVM Drives Anyone have any further tips for how to get the video preview to buffer less or process quicker? Maybe I have some settings wrong or maybe I can configure something differently so this isn't a problem? Or is this just something Video-pad does? This happens even though my preview is set at 360p.

borate Posted August 7, 2017 Share Posted August 7, 2017 Choose a lower preview resolution to see if that helps. If practicable please share the project so others can attempt to duplicate your issue. Click FILE|SAVE AS PORTABLE PROJECT. Upload the resultant folder/files to DropBox, Google Drive, MS OneDrive or the like and post a public link here.

thefsm93 Posted August 7, 2017 Author Share Posted August 7, 2017 Lower resolution doesn't seem to help, and the processor doesn't seem to spike in usage when there is a delay/buffer. I'll try to upload something tonight I can share. Link to comment Share on other sites More sharing options...
borate Posted August 7, 2017 Share Posted August 7, 2017 You might also look under the OPTIONS|EDITING tab. Check or UNcheck the "use hardware-accelerated video effects" box to see if that affects performance. Link to comment Share on other sites More sharing options...
Nationalsolo Posted August 7, 2017 Share Posted August 7, 2017 Hi If you are using 16:9 video (720p or 1080 etc.) Click Tools/Options and under the Display tab click the down arrow next to the right of the Preset box. Select 512 x 288 (16:9) and see if that speeds things up. (Ought to) My PC .... Vista Windows Vista Édition Familiale Premium 32-bit SP2 Intel Core 2 Duo E4500 @ 2.20GHz 2.00 Go RAM Single-Channel DDR2 @ 266MHz (4-4-4-12) NVIDIA GeForce GT 730 (Gigabyte) 2047MB .....nearly always shows a Preview buffering warning if the preview is greater than 1074 x 576 and if set any higher there is a huge delay while the thumbnails in the bin and the timeline are regenerated and playing a sequence is a non starter. At 640 x 360 it runs fine. Nat Link to comment Share on other sites More sharing options...
c_major Posted August 7, 2017 Share Posted August 7, 2017 The current caching system is clip based meaning that tracks are composed during playback. If you have a lot of tracks, it will slow down preview significantly. Link to comment Share on other sites More sharing options...
thefsm93 Posted August 8, 2017 Author Share Posted August 8, 2017 Dropping to 512 x 288 didn't seem to have much effect, and turning off hardware acceleration made things much worse! I did however start giving it more time to process and buffer and that seemed to help I might also try re-imaging this machine at somepoint in the future to see if that will help.

Dangerfreak Posted August 12, 2017 Share Posted August 12, 2017 I have the same problem, powerful computer, but I always get "buffering" while previewing (the more clips, the worse). Changing the preview resolution or the fps doesn't help. The preview also gets stuck nearly after every clip/scene. And once the preview is running, I often can't stop it anymore - the video is stuck, sound is still playing, but videopad does not respond to any interactions. Sometimes I have to wait until the whole sequence is over, before I can continue working with videopad. However, I think I know the reason for that. If I change the preview fps to any value, the preview doesn't get stuck after one clip (no buffering) - unfortunately for a few seconds only. I'm pretty sure, it has something to do with the background queues (videopad is always working in the background). These background processes obviously are so demanding, that the preview doesn't have enough CPU time to work correctly. Unfortunately there is no way to stop these background processes...

Nationalsolo Posted August 12, 2017 Share Posted August 12, 2017 Hi Check the CPU % usage in the task manager. Is it running at 100% when VP is working? Also do you clear the cache after every editing session? If you do, then VP has to recache your files from your project file data and although it may load them and give the appearence that it is ready for you to edit ,it may still be generating thumbnails and organising the clips and edits in the background, particularly for a project with lots of clips, effects, edits and tracks. Trying to change things or play the project while this is happening will be subject to stops and starts and building preview messages. If you only have one project, load it and then clear the cache of unused files. You only need to do this once . That project will load much more quickly when you next come to edit. Obviously if you clear the cache before you start a session you delete, in effect all the project data which then has to be regenerated.

Dangerfreak Posted September 16, 2017 Share Posted September 16, 2017 Unfortunately it has nothing to do with the cache. Even after I let VP do all its caching and the cpu has enough free time, I have the buffering problem as described above. Link to comment Share on other sites More sharing options...

No matter the computer, hardware, or preview setup, performance is bad. This is because unlike the rest which uses real-time processing, VP processes all effects and what not, then encodes them for preview (at least that's what I can infer). Sadly I don't think they utilize hardware encoding which makes lives soo much easier for us. QuickSync and alike is very common today. Everybody should be able to duplicate the problem. I just want to sign this statement. It happens for me all the time as well. I've spent $60 on a software, and the developers should put all their effort in improving the preview video. It has never been an issue when I used Adobe Premiere Elements, which is somewhat comparable to VideoPad in many aspects. Link to comment Share on other sites More sharing options...
