danik56 Posted February 28, 2021 Share Posted February 28, 2021 I am trying to trim a few min from the tail end of a 1.2GB MP4 file. Original bitrate is 3800 kbs The output file created is 187MB with 600 kbs bitrate Is it possible to keep the original bitrate ? Link to comment Share on other sites More sharing options...
Nationalsolo Posted February 28, 2021 Share Posted February 28, 2021 Hi You can set the export bitrate in the Export File Settings window. Set the File Format (mp4) and then click the option to the right in blue (Default Quality/File Size.) This brings up the mp4 Encoding Settings. Click the VideoQuality/Bitrate option down chevron and select the required bitrate from the drop down list. Nat Link to comment Share on other sites More sharing options...
danik56 Posted February 28, 2021 Author Share Posted February 28, 2021 Is this export bitrate setting really working? Even when I select 40000kbs the file size is less than 200MB with bitrate of 300kbs. Link to comment Share on other sites More sharing options...
borate Posted February 28, 2021 Share Posted February 28, 2021 Works here. Try LOSSLESS (from the toolbar). 39.9Mb bitrate 1.53Gb original exported at nearly the same bitrate with resulting file size of 1.67Gb, after trimming off several minutes. If that fails, try H264 with Off (Re-encode Video) selected in the Lossless Export field. Result Link to comment Share on other sites More sharing options...
c_major Posted March 1, 2021 Share Posted March 1, 2021 The best way to avoid quality loss is to use lossless export - by leave the default export options. VideoPad support lossless transcoding for h.264 and MPEG4 codecs. Video data are simply copied from the input video to the output, without the trimmed section. Please note that if the input and output format does not match or the codec is not supported, the video must be re-encoded. Re-encoding is always lossy.

danik56 Posted March 1, 2021 Author Share Posted March 1, 2021 Exporting with MPEG4 and lossless seems to maintain the original bitrate. Thanks Link to comment Share on other sites More sharing options...
borate Posted March 1, 2021 Share Posted March 1, 2021 Should do the job nicely. Just click the LOSSLESS button on the toolbar. Link to comment Share on other sites More sharing options...
