danicx Posted May 11, 2016 Share Posted May 11, 2016 Hi! Is it way to save maximum quality of output video without re-encoding? When i join few videos with same parameters (fps, dimension and codec) and my output video have the same, it seems quality is lossing. (in codec option I select maximum quality if possible) You can see artefacts and blir in screenshot Link to comment Share on other sites More sharing options...
borate Posted May 11, 2016 Share Posted May 11, 2016 Effective with version 3.89, the VP release notes stated the following... "When exporting video in H.264 format. VideoPad will perform lossless transcoding whenever possible. It will increase exporting speed dramatically while maintain the original quality of the video. Lossless transcoding can only be applied to non-altered (no overlaying, effect and transitions) sections." Link to comment Share on other sites More sharing options...
c_major Posted May 11, 2016 Share Posted May 11, 2016 Lossless editing can be enabled in Options->Export->Other->Enable lossless video exporting. Link to comment Share on other sites More sharing options...
danicx Posted May 11, 2016 Author Share Posted May 11, 2016 c_major, thank you ! I will try this. P.S. Just installed new version of VP and see there is no effects zoom and rotation. Is it deleted forever? Can I copy some files from folder with old version of VideoPad to return it? Link to comment Share on other sites More sharing options...
borate Posted May 11, 2016 Share Posted May 11, 2016 Click the VIDEO EFFECTS tab, or the FX icon in the clip on the time line, then the green + sign to add an effect. Both rotate and zoom are among the choices. Link to comment Share on other sites More sharing options...
danicx Posted May 11, 2016 Author Share Posted May 11, 2016 Borate, all effects is a loosing information from moovie. But I try only to save it. So I did some experiment. First I set option "losless exporting" and set export settings to avi and H.264 codec: Than I make moovie from picture from post 1. Than replace picture by moovie and make moovie2. After 5 steps I compare picture, moovie1 and moovie5. (To better viewing i set levels and brightness in Photoshop). So, losless encoding is not workin or I do something wrong. Look at result: Link to comment Share on other sites More sharing options...
c_major Posted May 12, 2016 Share Posted May 12, 2016 What's the format of the original video? Lossless export only works when input video are also H.264. It simply moves the packages from the input to the output without decoding and encoding. Link to comment Share on other sites More sharing options...

c_major Posted May 13, 2016 Share Posted May 13, 2016 This currently only works for H.264 Annex B files. Lossless feature is still experimental and still need more work. Link to comment Share on other sites More sharing options...
