Waveforms are different. [IMG]http://images.vfl.ru/ii/1604493972/481e6920/32179778_m.jpg[/IMG] And different are every peak, I marked just most visible. This can be seen even without approximation. Of course its not native language for you and its hard for perception, but distortion are really present and it looks like snarling at low frequency.

Long time I could not understand why I recording video with good sound, but after downloading it to youtube the result is with bad sound. I assumed problem with youtube's re-encoding (but why only in my video?). Bot now I understand that sound is getting bad after export by Videopad even if nothing changes and make lossless export. I chek it in versions 6.32-8.33 - everywhere the same. The problem is clearly audible when sounding just talk voice - low frequencies distorted to much and its sounds like some overload. Lowering the volume even to 50% doesn't help - result are quieter but with the same distored. It's very strange, considering that export are lossless and without any changes. So question - how get rid of this problem? Attached 2 files - original sound.m4a and result sound.mp4 (exported with 1*1 pixel black screen video, so it does not need export portable project) - https://drive.google.com/drive/folders/17SI6t7C8KmgHd58uC-Mo4iL4VmUaEejY?usp=sharing. Distortion audible very good, even at bad sound system like phone speaker. But especially if open both audio at audacity for example and turn on solo in rotation.

As early - my exported video doesn't have photo at the end - just last frame from video few second (VLC player) or even nothing in google drive player (youtube same) - https://photos.app.goo.gl/8gE4xvxuDsgLkg4J9 Using lossless too.

Some times ago I started other topic with same problem - http://nch.invisionzone.com/topic/30531-lossless-export-stick-2-video-files-stick-video-photo/. Unfortunately problem wasn't resolve so i still use version 6.xx. Today I try again version 8.33 (russian) and understand where are problem - when I add some photo cache doesn't create for it! That's why it can't export correctly. I use Windows 7 64 bit (and 32 bit try too).

Its very strange... What system you use? I do it windows 7 64 bit and additional testing on windows 7 32 bit - both have same problems. I upload my result video same folder. What interesting - when I open it with VLC player there is no photo with 4 fingers at all, just last frame with pause; if it play by google drive player (it do new converting when upload) - will just one photo middle; if using GOM player you will see both photo, but rewinding work not correct this area.

Yes , my video meets the requirements. Step just one - lossless export of my project. In result second one should have picture with 4 fingers a few seconds two times - middle and end video, but after export I haven't it. In first project 3 videos should be stick without converting, but 2 of 3 do full converting/

Last ~6 month I used version 6.32 RUS and have one problem: when I try stick few videos maked by same camera and export it with lossless options - just one part realy export with lossless (fast), but every other one with full converting (slowly). For version 7.xx and 8.xx its the same problem. So i should first use other videoeditor to stick videos, and after videopad for editing 1 big file. Second problem reveal itself when I update to 8.20 (en or ru nevermind): when I try add pictures or text to video after lossless export I take no this picture, but just last frame of video before or even nothing. For version 7.xx its the same problem, but 6.32 have no it! So I return back 6.32. I make 2 portable projects with this problems - https://drive.google.com/open?id=17SI6t7C8KmgHd58uC-Mo4iL4VmUaEejY

I think you have same problem as me - your video using not the H264 encoder. As borate wrote - video "does not meet the requirements for lossless export". Exactly such error wrote VP, but unfortunaly without details about nesessery encoder. And russian version VP wrote just "Failed"...

Thanks for result - downloaded it! Didn't know about such requirements, VP doesn't notify about it when starting export. I'm not sure,but it seems to me that problems sometimes happens and with correct codec. Will try further... Thanks one more time!

I have the same problem not first time. When after editing I start lossless export very often export stop at some split point (where was cut some part video) and take error. Using ver 6.32 (last russian) or 7.39 (en) - same problem both. Error something like "your file can't be export". But if I add some picture or text on this split - export can continue to next split. Also sometimes help additional cutting little parts near this split. Anyway its torture while video will export... By the way, esealy define where export stop (which second) - open export file (part of it) in videoplayer. VLC for example. I use windows 7 64 bit, videopad cache try clearing too, unistall/reinstall - nothing help. So maybe someone know good solution - I will very appreciative. upd: trying export at other pc with windows 7 32 bit - same result.
