fredgolightly Posted March 30, 2017 Share Posted March 30, 2017 Hi, I'm trying to join and edit some .m2ts videos from a Panasonic video camera. It outputs .m2ts files which have video avc codec, as per: General ID : 1 (0x1) Complete name : E:\David\Desktop\New folder\1080p 25fps m2ts.m2ts Format : BDAV Format/Info : Blu-ray Video File size : 33.1 MiB Duration : 22 s 63 ms Overall bit rate mode : Variable Overall bit rate : 12.6 Mb/s Maximum Overall bit rate : 18.0 Mb/s Video ID : 4113 (0x1011) Menu ID : 1 (0x1) Format : AVC Format/Info : Advanced Video Codec Format profile : High@L4 Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Codec ID : 27 Duration : 22 s 0 ms Bit rate mode : Variable Bit rate : 11.7 Mb/s Maximum bit rate : 16.8 Mb/s Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate : 25.000 FPS Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Interlaced Scan type, store method : Separated fields Scan order : Top Field First Bits/(Pixel*Frame) : 0.225 Stream size : 30.6 MiB (93%) Audio ID : 4352 (0x1100) Menu ID : 1 (0x1) Format : AC-3 Format/Info : Audio Coding 3 Mode extension : CM (complete main) Format settings, Endianness : Big Codec ID : 129 Duration : 22 s 112 ms Bit rate mode : Constant Bit rate : 384 kb/s Channel(s) : 6 channels Channel positions : Front: L C R, Side: L R, LFE Sampling rate : 48.0 kHz Frame rate : 31.250 FPS (1536 spf) Bit depth : 16 bits Compression mode : Lossy Delay relative to video : -80 ms Stream size : 1.01 MiB (3%) However, when I come to export, despite no transcode-needing edits done (ie just plonking one file into the timeline and exporting) and the lossless export enabled, the file is re-encoded. Are .m2ts files not supported for lossless cutting/joining in Videopad? I'm using 5.01, and have uploaded a few sample files plus my log to: https://www.dropbox.com/sh/7wr9b4lyjvuuhcm/AAChEccuKCutX_iyAZh60O4Ua?dl=0 if anyone can help me out with what's stopping the export be lossless. Any info would be so gratefully received Link to comment Share on other sites More sharing options...
c_major Posted April 2, 2017 Share Posted April 2, 2017 At the moment VideoPad only supports non-destructive editing for H.264 codec with Enable lossless video exporting option turned on. We are continuously working on it to improve it and adding support to more codecs. Link to comment Share on other sites More sharing options...

Well I tried editing/exporting losslesspy with it enabled and on these files, which are h264 (avc is h264) but no luck. Am I doing it wrong or is this h264 file not supported?

c_major Posted April 3, 2017 Share Posted April 3, 2017 In order to export lossless, following conditions must applied: Input and output codec must be H.264 and with same codec settings. Output frame rate and resolution must be the same as input. Timeline section where effects are applied can not be lossless. Timeline section where transitions are applied can not be lossless. Timeline section where contains more than one tracks can not be lossless. We are doing a rework on this feature in order to avoid the confusion.

Clip meets all conditions, I've tried adding the same clip in twice, even just once in it's own, and it's h264 as per sample uploaded, but it still exports lossy :/ Link to comment Share on other sites More sharing options...

fredgolightly Posted April 3, 2017 Author Share Posted April 3, 2017 Great, thanks so much again! Killer app once this is fixed - I've literally spent days looking into this, tried nearly 20 programs, and none do this! Link to comment Share on other sites More sharing options...
